Lasix (Furosemide)

Rating of sales:          


Lasix is a highly effective FDA approved medication for the treatment of excessive edema (fluid retention) due to kidney disorder (nephrotic syndrome), heart failure, cirrhosis and liver disease. It is also used to treat high blood pressure (hypertension). Lasix works by regulating the way in which the body absorbs salts.

Bumex, Edecrin, Demadex, Sodium Edecrin, Fluss 40


Also known as:  Furosemide.


Lasix prevents excessive edema (fluid retention) in people with kidney disorder (nephrotic syndrome), heart failure, cirrhosis and liver disease. It is also used for the treatment of high blood pressure (hypertension), high levels of potassium (hyperkalemia), calcium (hypercalcemia), and magnesium (hypermagnesemia).

The active component, Furosemide, is a potent loop diuretic (water pill) that eliminates water and salt from the body. Furosemide works by blocking the absorption of sodium, chloride, and water from the filtered fluid in the kidney tubules, causing a profound increase in the output of urine (diuresis).

Lasix starts to act within one hour after oral administration, and the effect lasts for about 6-8 hours.


Lasix is available in tablets which should be taken orally with a full glass of water.

The dosage of Lasix depends on the body weight and on the health status of the recipient.

Take Lasix at the same time once a day.

Do not take more than your recommended dose, as high doses of furosemide may cause irreversible hearing loss.

Do not crush or chew the tablet.

To achieve the most effective results, do not stop taking Lasix suddenly.


In case of a Lasix overdose visit your doctor or health care provider immediately. Symptoms of a Lasix overdose include fainting, tinnitus, confusion, weakness, lightheadedness, lack of appetite.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) away from moisture, light and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

To evaluate the feasibility and efficacy of robotic-assisted laparoscopic pyeloplasty. Laparoscopic pyeloplasty has been shown to have a success rate comparable to that of the open surgical approach. However, the steep learning curve has hindered its acceptance into mainstream urologic practice. The introduction of robotic assistance provides advantages that have the potential to facilitate precise dissection and intracorporeal suturing.

Human carbonic anhydrase II (CA II), a zinc metalloenzyme, was screened against 960 structurally diverse, biologically active small molecules. The assay monitored CA II esterase activity against the substrate 4-nitrophenyl acetate in a format allowing high-throughput screening. The assay proved to be robust and reproducible with a hit rate of approximately 2%. Potential hits were further characterized by determining their IC(50) and K(d) values and tested for nonspecific, promiscuous inhibition. Three known sulfonamide CA inhibitors were identified: acetazolamide, methazolamide, and celecoxib. Other hits were also found, including diuretics and antibiotics not previously identified as CA inhibitors, for example, furosemide and halazone. These results confirm that many sulfonamide drugs have CA inhibitory properties but also that not all sulfonamides are CA inhibitors. Thus many, but not all, sulfonamide drugs appear to interact with CA II and may target other CA isozymes. The screen also yielded several novel classes of nonsulfonamide inhibitors, including merbromin, thioxolone, and tannic acid. Although these compounds may function by some nonspecific mechanism (merbromin and tannic acid), at least 1 (thioxolone) appears to represent a genuine CA inhibitor. Thus, this study yielded a number of potentially new classes of CA inhibitors and preliminary experiments to characterize their mechanism of action.

The dynamic range in which renal blood flow (RBF) autoregulation occurs was determined in eight conscious foxhounds chronically catheterized in the abdominal aorta and implanted with a transit-time flow probe over the renal artery. Sinusoidal driving pressures (amplitude of 10 mmHg) were forced on the renal arterial pressure at different frequencies by a servo-control device, and transfer functions were calculated. Only one frequency range was found below which the gain of the transfer function declined and in which the phase angle increased (n = 8). This indicates the presence of a potent mechanism for renal autoregulation in the examined frequency range between 0.0031 and 0.08 Hz, which buffers changes in blood flow < 0.02 Hz. After furosemide treatment, one indicator for autoregulation (phase shift of transfer function) was significantly blunted at low frequencies (n = 6). Furosemide, however, did not reduce the phase shift to zero, suggesting that some autoregulation still remained in the frequency range between 0.04 and 0.08 Hz. In conclusion, autoregulation of RBF during sinusoidal changes in driving pressure between 0.0031 and 0.02 Hz is mediated by a single mechanism, which can be blocked by the acute administration of furosemide. The residual phase shift between arterial pressure and RBF in the transfer function observed during sinusoidal changes in driving pressure between 0.04 and 0.08 Hz suggests the presence of a second mechanism for RBF autoregulation.

Loop diuretics are prescribed commonly, particularly in the elderly. There is no clear pattern of documented clinical features that leads to prescription of these drugs. Open access echocardiography is rarely used to aid diagnosis. ACE inhibitors are under-prescribed and under-dosed in patients diagnosed with heart failure in this study population.

A 35-year-old man, a heavy smoker, was admitted to the hospital because of lobar pneumonia. Despite wide spectrum antimicrobial therapy, he developed ARDS and was placed on a ventilator. Standard ventilation was ineffective and veno-venous ECMO was instituted. The extravascular lung water index (EVLWI) was extremely high (over 30 mL kg-1) and signs of a hyperdynamic circulation (CI 6.1 L m-2 min-1) were observed. Modification of the inotropic support and continuous infusion of furosemide resulted in normalisation of the hydration status, and over a week of ECMO therapy, the patient's general condition improved to the stage that he was scheduled to be weaned from extracorporeal treatment. On the 7th day however, he suddenly deteriorated. A lung CT-scan revealed bilateral pneumothoraces and diffuse pulmonary embolism. Three thoracic drains were inserted, but unfortunately, the drainage was complicated by massive bleeding and a subsequent thoracotomy. Two days later, a gastrointestinal haemorrhage occurred. Heparin dosage was reduced, and ECMO was discontinued and replaced with HFOV. This resulted in adequate oxygenation, however because of ineffective CO2 elimination, pumpless arteriovenous extracorporeal lung assist (PECLA) was instituted, allowing conventional ventilation to be resumed after 8 days. The further clinical course was complicated by persistent bilateral pneumothoraces, pleural effusion and Pseudomonas nosocomial infection. The man eventually recovered after 54 days in the ICU, and was transferred to a rehabilitation department.

We investigated whether in vitro human endothelial and renal epithelial cells responded to torasemide or furosemide with enhanced secretion of the vasodilator prostaglandin prostacyclin (PGI2). We also investigated the effects of loop diuretics on plasma concentrations of PGI2 and its physiological antagonist thromboxane after 25 min of administration of drugs in 44 patients with congestive heart failure (CHF) and 44 healthy volunteers.

Removal of external Ca2+ facilitated endogenous taurine release in cultured rat astrocytes. The stimulated release was not affected by furosemide, sucrose, tetrodotoxin and 3,4-dichlorobenzamil, but partially inhibited by nifedipine. Omission of external Na+ increased basal taurine release, and the effects of Na+ removal and Ca2+ depletion on the release were additive. The Na(+)-free condition did not affect Ca2+ paradox-induced cell death in astrocytes. These findings suggest that Ca2+ depletion facilitates taurine release in a mechanism independent of volume and the Na+ gradient and that the release is not involved in Ca2+ paradox-induced delayed cell toxicity in astrocytes.

The first-pass effect of furosemide was investigated in rats. Furosemide intravenous solution (20 mg kg(-1) Lasix), was administered via the jugular vein and the portal vein, orally, and instilled directly into the duodenum of rats. The first-pass effects of furosemide by lung, heart, and liver seemed to be negligible in rats. The absolute bioavailability of furosemide was 28.9 and 48.3% after oral and intraduodenal administration, respectively. Based on the gastrointestinal (GI) recovery study, 68.3 and 69.5% of furosemide were found to have disappeared mainly due to absorption and/or metabolism from rat GI tract after oral and intraduodenal administration, respectively. The results indicate that gastrointestinal and intestinal first-pass effects of furosemide were approximately 40% (68.3-28.9%) and 20% (69.5-48.3%) of the dose, respectively.

We assessed the acute bronchodilator effect of nebulized furosemide when added to conventional therapy of acute emergency department (ED) asthma. Using a double-blind design, 42 patients with acute asthma were randomized to receive 2.5 mg nebulized salbutamol and either 40 mg of nebulized furosemide or saline solution. We recorded clinical variables (respiratory rate, heart rate, and pulsus paradoxus) and peak expiratory flow rates (PEFR) before and 15 and 30 min after therapy. We found no significant difference in PEFR between salbutamol/furosemide and salbutamol/saline-treated patients 15 and 30 min following inhalation. Other endpoints were equally unaffected. However, when we examined separately those patients whose exacerbations were of relative short duration (< 8 hr), PEFR improved significantly more in the furosemide-treated group. At 15 min, PEFR increased by 82 +/- 48% in the furosemide group compared to 35 +/- 40% in the control group (p = 0.03), an effect that was also evident at 30 min when PEFR had increased by 113 +/- 49% in the furosemide group versus 61 +/- 35% in the control group (p = 0.014). Respiratory rate, heart rate, and pulsus paradoxus improved with no differences between the groups. The beneficial effect of furosemide was not evident in patients who reported more prolonged duration (> 8 hr) of asthmatic symptoms. The response to furosemide appeared to be unrelated to concomitant ED therapy with corticosteroids, to baseline pulmonary function, or to patient demographic variables. We conclude that furosemide may offer additive bronchodilator benefits in acute naturally occurring asthma of relative short duration.

The effect of furosemide infusion was studied in 6 normal subjects and 6 patients with severe COPD and right ventricular failure during normoxemia and hypoxemia. In normal subjects, hypoxemia alone caused an insignificant (p less than 0.15) fall in plasma aldosterone concentrations (PAC). Intravenously administered furosemide resulted in significant (p less than 0.05) increases in PAC during both normoxemia and hypoxemia. After furosemide treatment mean arterial pressure (MAP) was significantly lower and arginine vasopressin (AVP) was significantly higher (p less than 0.05) with hypoxemia than with normoxemia. These changes in MAP and AVP were strongly correlated (r = -0.84). Urinary losses of water and sodium were similar after furosemide treatment with hypoxemia and normoxemia. In patients with right ventricular failure, neither changes in oxygenation nor furosemide infusion affected the markedly elevated baseline PRA and PAC levels. Arginine vasopressin levels were significantly higher with hypoxemia than with normoxemia, but urinary losses of water and salt did not differ between the 2 study days. We conclude that hypoxemia does not affect the PAC increase or urinary volume and sodium response to furosemide.

Pharmacokinetic interactions involving anti-infective drugs may be important in the intensive care unit (ICU). Although some interactions involve absorption or distribution, the most clinically relevant interactions during anti-infective treatment involve the elimination phase. Cytochrome P450 (CYP) 1A2, 2C9, 2C19, 2D6 and 3A4 are the major isoforms responsible for oxidative metabolism of drugs. Macrolides (especially troleandomycin and erythromycin versus CYP3A4), fluoroquinolones (especially enoxacin, ciprofloxacin and norfloxacin versus CYP1A2) and azole antifungals (especially fluconazole versus CYP2C9 and CYP2C19, and ketoconazole and itraconazole versus CYP3A4) are all inhibitors of CYP-mediated metabolism and may therefore be responsible for toxicity of other coadministered drugs by decreasing their clearance. On the other hand, rifampicin is a nonspecific inducer of CYP-mediated metabolism (especially of CYP2C9, CYP2C19 and CYP3A4) and may therefore cause therapeutic failure of other coadministered drugs by increasing their clearance. Drugs frequently used in the ICU that are at risk of clinically relevant pharrmacokinetic interactions with anti-infective agents include some benzodiazepines (especially midazolam and triazolam), immunosuppressive agents (cyclosporin, tacrolimus), antiasthmatic agents (theophylline), opioid analgesics (alfentanil), anticonvulsants (phenytoin, carbamazepine), calcium antagonists (verapamil, nifedipine, felodipine) and anticoagulants (warfarin). Some lipophilic anti-infective agents inhibit (clarithromycin, itraconazole) or induce (rifampicin) the transmembrane transporter P-glycoprotein, which promotes excretion from renal tubular and intestinal cells. This results in a decrease or increase, respectively, in the clearance of P-glycoprotein substrates at the renal level and an increase or decrease, respectively, of their oral bioavailability at the intestinal level. Hydrophilic anti-infective agents are often eliminated unchanged by renal glomerular filtration and tubular secretion, and are therefore involved in competition for excretion. Beta-lactams are known to compete with other drugs for renal tubular secretion mediated by the organic anion transport system, but this is frequently not of major concern, given their wide therapeutic index. However, there is a risk of nephrotoxicity and neurotoxicity with some cephalosporins and carbapenems. Therapeutic failure with these hydrophilic compounds may be due to haemodynamically active coadministered drugs, such as dopamine, dobutamine and furosemide, which increase their renal clearance by means of enhanced cardiac output and/or renal blood flow. Therefore, coadministration of some drugs should be avoided, or at least careful therapeutic drug monitoring should be performed when available. Monitoring may be especially helpful when there is some coexisting pathophysiological condition affecting drug disposition, for example malabsorption or marked instability of the systemic circulation or of renal or hepatic function.

Out of a series of pyridine-3-sulfonylureas with diuretic activity torasemide (1-isopropyl-3- ([4-(3-methyl-phenylamino)pyridine]-3-sulfonyl)urea) has been proved to be one of the most active derivatives. In the rat, urinary volume and electrolyte excretions increased linearily with the logarithm of the dose, thus resembling the profile of a high ceiling diuretic. Experiments by oral and intravenous routes indicated that torasemide was equally potent both by oral and parenteral administration. Compared to furosemide, torasemide was 9-40 times more potent on weight basis in the rat. For the same natriuretic effect, however, potassium losses with torasemide were significantly less than with furosemide. The diuretic effect of torasemide lasted longer compared to that of furosemide. In accordance with the pharmacodynamic characteristics plasma elimination half-life of torasemide was about 1.5 h in the rat and bioavailability was nearly complete. Torasemide was 98-99% bound to plasma proteins. No in vitro interaction was found with the cumarine derivative warfarin.

Past research has demonstrated that when an animal changes from a previously drug-naive to an opiate-dependent and withdrawn state, morphine's motivational effects are switched from a tegmental pedunculopontine nucleus (TPP)-dependent to a dopamine-dependent pathway. Interestingly, a corresponding change is observed in ventral tegmental area (VTA) GABAA receptors, which change from mediating hyperpolarization of VTA GABA neurons to mediating depolarization.

Gitelman's syndrome is a rare autosomal recessive, renal tubular disorder, characterized by chronic hypokalemia, hypomagnesemia, metabolic alkalosis, hypocalciuria, and normal blood pressure. Patients usually present at a later age with episodic mild muscle weakness. Unexplained hypokalemia arouses suspicion. The diuretic loading test with furosemide and thiazide and the use of Bartter's normogram provides a practical and simple tool in comparison to the complex and costly genetic analysis, to confirm the diagnosis. Here we report a case of Gitelman's syndrome to show the utility of these simple techniques to explain the pathophysiology of the disease, as well as to localize the site of the renal tubular defect, to confirm the diagnosis.

Primary cultures of structurally polarized sheets of avian salt gland secretory cells were mounted in Lucite chambers for transmural electrophysiological analysis. Transmural resistance values increased during the first 3 days of culture to 293 +/- 35 omega X cm2 and then decreased slowly thereafter. There was little short-circuit current (Isc) in the absence of secretagogues. Serosal addition of either carbachol or epinephrine resulted in a Isc consistent with positive charge flow from mucosa to serosa, thus demonstrating that these cell layers were capable of active ion transport in response to either cholinergic or adrenergic neurohormonal stimulation. buy lasix Serosal ouabain or furosemide abolished the response to either agonist, while theophylline enhanced the response. Receptor specificity for the electrical responses was shown by selective inhibition of carbachol- and epinephrine-induced Isc by atropine and propranolol, respectively. The results demonstrate that these primary epithelial cell cultures are capable of active ion transport and are sensitive to known inhibitors of secretory transport, and suggest that intracellular coupling mechanisms for hormonal control are retained in culture. These cultures should be useful for studying mechanisms of ion secretory transport and their regulatory control.

A 66-year-old woman with a history of hypertension, parkinsonism, rheumatoid arthritis, anxiety and depression, and symptoms of Sjögren syndrome was seen with a 1-month history of an eruption on her upper extremities and upper trunk. The eruption had begun 2 to 3 weeks after subcutaneous injection of golimumab for rheumatoid arthritis. She had developed SCLE 2 years previously due to furosemide use and 10 years previously due to hydrochlorothiazide use. Physical examination revealed scaly, annular, erythematous plaques photodistributed on the arms, legs, and upper trunk. A punch biopsy specimen demonstrated vacuolar interface dermatitis and lymphohistiocytic perivascular inflammation. Serological abnormalities included a positive antinuclear antibody, an elevated anti-La/SS-B antibody level, and an elevated anti-Ro/SS-A antibody level. She was diagnosed as having SCLE and was initially treated with desonide lotion, photoprotection, prednisone (40 mg/d) tapered over 6 weeks, and hydroxychloroquine sulfate (200 buy lasix mg twice daily). Because of persistent disease, methotrexate sodium (12.5 mg/wk) was subsequently added to the regimen, and her eruption cleared completely.

Small cryopreserved allografts for use in neonates and infants are increasingly difficult to find. We describe a technique for surgically reducing the size of the more readily available large-diameter allografts to make them conform to size requirements appropriate for neonates and infants. This technique involves a longitudinal incision of the allograft from its muscular annulus to its distal orifice with the excision of a single valve leaflet. The two commissural posts of the excised leaflet and the wall of the allograft are then reapproximated with fine suture. Four patients ranging in age from 14 days to 11 months (mean age, 5.2 months) and ranging in weight from 3 to 8.4 kg (mean weight, 5.2 kg) underwent reconstruction of the right ventricular outflow tract using this surgical technique. Two patients underwent repair of truncus arteriosus (age, 14 days and 16 days) and two patients underwent Rastelli operations (age, 9 months and 11 months). The mean follow-up time was 22.5 months (range, 14 to 28 months). All 4 patients are alive and well. One patient requires digoxin and furosemide for moderate quadricuspid truncal valve insufficiency. Serial echocardiography documents mild allograft stenosis in 2 patients and buy lasix trivial to mild allograft insufficiency in 2 patients. Because handling characteristics and lower bleeding risks render allograft conduits preferable to synthetic conduits and, furthermore, because conduit insertion of any type in the neonate will eventually be outgrown and require replacement, we find this technique to be justifiable as a therapeutic option. In the short term, the technique results in excellent functional results and provides an alternative to synthetic conduits when an appropriate sized allograft is unavailable.

Central α2-adrenoceptors and the pontine lateral parabrachial nucleus (LPBN) are involved in the control of sodium and water intake. Bilateral injections of moxonidine (α2-adrenergic/imidazoline receptor agonist) or noradrenaline into the LPBN strongly increases 0.3 M NaCl intake induced by a combined treatment of furosemide plus captopril. Injection of moxonidine into the LPBN also increases hypertonic NaCl and water intake and reduces oxytocin secretion, urinary sodium, and water excreted by cell-dehydrated rats, causing a positive sodium and water balance, which suggests that moxonidine injected into the LPBN deactivates mechanisms that restrain body fluid volume expansion. Pretreatment with specific α2-adrenoceptor antagonists injected into the LPBN abolishes the behavioral and renal effects of moxonidine or noradrenaline injected into the same area, suggesting that these effects depend on activation of LPBN α2-adrenoceptors. In fluid-depleted rats, the palatability of sodium is reduced by ingestion of hypertonic NaCl, limiting intake. However, in rats treated with moxonidine injected into the LPBN, the NaCl palatability remains high, even after ingestion of significant amounts of 0.3 M NaCl. The changes in behavioral and buy lasix renal responses produced by activation of α2-adrenoceptors in the LPBN are probably a consequence of reduction of oxytocin secretion and blockade of inhibitory signals that affect sodium palatability. In this review, a model is proposed to show how activation of α2-adrenoceptors in the LPBN may affect palatability and, consequently, ingestion of sodium as well as renal sodium excretion.

The slower elimination and the lower total body clearance (CLtot) values of M17055 in dogs reflect the difference of the no-effect level (NOEL) between rats (0.1 mg/kg) and dogs (0.03 mg/kg) well. The diuretic response was well correlated with the urinary M17055 excretion rate by fitting to a sigmoid E(max) model in both rats and dogs. The derived ER(50) value of M17055 in dogs was approximately 10 times less than that reported for furosemide, suggesting that the intrinsic potency of M17055 is equal to or higher than those of other powerful loop diuretics. Although diuretic sensitivity was considered to be lower in dogs than in rats, the higher amount of M17055 reaching the dog kidney is likely to compensate for this. The diuretic response in female rats was predictable by using the pharmacodynamic parameters derived from male rats. These results show that the apparent high diuretic potency and the other pivotal observations for M17055 found in the pharmacological and toxicological studies can be rationalized by the pharmacokinetic and pharmacodynamic properties of the unchanged compound.

A retrospective review of 107 MRU exams obtained to evaluate for possible upper urinary tract urothelial carcinoma from 5/2005 to 5/2009 was performed by two experienced abdominal radiologists. Interpretation of the presence or absence of bladder carcinoma and lesion conspicuity in each imaging phase was made using 5-point confidence grading scales. Exams included 3D T1-weighted spoiled gradient-recalled echo images through the kidneys, ureters and bladder in the coronal plane during parenchymal phases and in both coronal and axial planes during pyelographic phases after intravenous administration of gadolinium and furosemide. Standard of reference was cystoscopy or cystectomy within 30 days of MRU. Statistical measures of performance, including receiver operating characteristics area buy lasix under the curve (Az) values were calculated.

The plasma concentration profile, urinary excretion rate and diuretic response were studied in anaesthetized dogs after an intravenous administration of torasemide or furosemide. The urinary excretion rate of furosemide decreased rapidly after administration. The plasma concentration, which is related to the urinary excretion profile, also decreased rapidly. The diuretic response, which reflected the excretion rate, occurred rapidly after administration but lasted for a short time. The urinary excretion rate of torasemide was much lower than that of furosemide and decreased slowly after administration. The plasma concentration also decreased slowly. The diuretic response to torasemide occurred more slowly but lasted longer than the response to furosemide. These results suggest that the diuretic response profile of either diuretic depends on their urinary excretion rate, and Nexium Reviews 2010 that the difference in the diuretic response between torasemide and furosemide may be explained by the different transfer rate of the drugs from the plasma to the nephron.

In the Moroccan traditional medicine, the ripe fruits of Carum carvi L. (Apiaceae) and the leaves of Tanacetum vulgare L. (Asteraceae/Compositae), two widely available plant materials, are used as diuretics. Since, the diuretic activity of these substances has not been investigated in scientifically controlled studies, the aim of the present study was to evaluate the diuretic potential of aqueous extracts of Carum carvi fruit (caraway) and the leaves of Tanacetum vulgare (tansy) in normal rats after acute and sub-chronic oral administration. Water extracts of Carum carvi and Tanacetum vulgare (100 mg/kg) or the reference drug, furosemide (10 mg/kg) were administrated orally to male Wistar rats and their urine output was quantitated at several intervals of time after the dose. After single doses of the extracts of both caraway seeds and tansy leaves, urine output was significantly increased at all time points, and at 24 h after the dose, the total volume of urine excreted was similar for the plant extracts and furosemide. Both extracts increased urinary levels of Na(+) and K(+), to about the same extent, while furosemide increased urinary levels of only Na(+) and Lopressor Hct Dose decreased urinary K(+). Despite changes in urinary excretion of the electrolytes, plasma Na(+) and K(+) levels were not affected by any of the three substances. In the 8-day sub-chronic study, all three substances induced significant diuresis and natriuresis; only tansy increased urinary potassium excretion. The plant extracts did not appear to have renal toxicity or any other adverse effects during the study period. In conclusion, water extracts of both Carum carvi and Tanacetum vulgare have strong diuretic action confirming their ethnopharmacological use. From the pattern of excretion of water, sodium and potassium, it may be deduced that there are atleast two types of active principals present in these extracts, one having a furosemide-like activity and the other a thiazide-like activity.

In vitro studies suggest that collecting duct-derived (CD-derived) endothelin-1 (ET-1) can regulate renal Na reabsorption; however, the physiologic role of CD-derived ET-1 is unknown. Consequently, the physiologic effect of selective disruption of the ET-1 gene in the CD of mice was determined. Mice heterozygous for aquaporin2 promoter Cre recombinase and homozygous for loxP-flanked exon 2 of the ET-1 gene (called CD-specific KO of ET-1 [CD ET-1 KO] mice) were generated. These animals had no CD ET-1 mRNA and had reduced urinary ET-1 excretion. CD ET-1 KO mice on a normal Na diet were hypertensive, while body weight, Na excretion, urinary aldosterone excretion, and plasma renin activity were unchanged. CD ET-1 KO mice Imitrex Tablet Ingredients on a high-Na diet had worsened hypertension, reduced urinary Na excretion, and excessive weight gain, but showed no differences between aldosterone excretion and plasma renin activity. Amiloride or furosemide reduced BP in CD ET-1 KO mice on a normal or high-Na diet and prevented excessive Na retention in salt-loaded CD ET-1 KO mice. These studies indicate that CD-derived ET-1 is an important physiologic regulator of renal Na excretion and systemic BP.

An infant born by cesarean delivery is at risk of having excessive pulmonary fluid which makes predisposition to transient tachypnea of the newborn (TTN), because fetal thorax compression during labor leads to the loss of large volumes liquid from the lungs. At birth, the pulmonary epithelium switches from predominantly facilitated Ondansetron Zofran Dosage Cl⁻ secretion to predominantly active Na+ reabsorption with the increase expression epithelial Na+ -channels (ENaC). Diminished activity or immaturity of this process may contribute to the development of TTN. Familial clustering of some TTN cases shows a genetic predisposition in the developing of this disorder. Antenatal glucocorticoids induce lung Na+ reabsorption by increasing the number and activity of channels even in hypoxia. Since a large release of fetal adrenaline occurs late in labor stimulating ENaC to start reabsorbing lung fluids, aerolized ß-agonists may be used in the treatment. Genetic predisposition for ß-adrenergic hyporesponsiveness may cause TTN in newborn period, and asthma/wheezing in older age groups. Although furosemide accelerates lung fluid resorption and cause pulmonary vasodilatation, oral or aerosolized furosemide cannot be recommended as treatment for TTN unless additional data become available.

Drug tolerance seems to develop rapidly after the administration of sequential doses of the same loop diuretic. We evaluated whether alternating different loop diuretics could achieve the same initial diuretic response in the newborn. In a randomized double crossover study, we examined the diuretic and saliuretic effects of alternating doses of furosemide and ethacrynic acid (1 mg/kg administered intravenously every 24 hours) in 10 newborns, who received the drugs in the following sequential order: (1) furosemide, (2) ethacrynic acid, and (3) furosemide (group 1, n = 5); and (1) ethacrynic acid (2) furosemide, and (3) ethacrynic acid (group 2, n = 5). Hourly urine specimens were collected for the determination of rates of urinary and fractional excretion of sodium, chloride, and potassium and of urinary flow, before and 6 hours after dosing. There were no differences between the groups at each dose for all parameters measured. A significant decrease in prediuretic and postdiuretic rates of urinary flow, in sodium and chloride excretion, and in the fractional excretion of these electrolytes was observed before and after dosing. The associated reduction in patients' weights suggested Requip Medication a depletion in plasma volume. In conclusion, consecutive alternation of furosemide and ethacrynic acid in the same newborn does not prevent the development of pharmacologic tolerance to loop diuretics, since diuresis, natriuresis, and chloriuresis decrease after successive sequential administration of these drugs.

Twenty-eight patients (11 females, 17 males), including 16 Propecia Name Brand children and 12 adults, aged 8 months-80 years old, were included in the study. The patients were admitted to hospital for hematochezia and melena (22) associated with abdominal pain (5): 3 patients repeatedly presented occult blood in their stools. Two patients only suffered from abdominal cramps and one only anemia. Patients were studied using plain abdominal radiographs and ultrasound; 10 underwent gastroscopy and colonoscopy; radiological contrast studies were performed in 5 patients. All tests were inconclusive. All the patients were premedicated with oral cimetidine (20 mg/kg in pediatric patients and 300 mg q.i.d. for adults, 48 hours before the test) or with ranitidine i.v. (1 mg/kg, max 50 mg, in 20 minutes, one hour before the test); barium meals and colonoscopy were deferred for 2-3 days after examination. An intravenous injection of 37-180 Mbq of 99mTcO4 was given followed by a dynamic study of the abdomen in anterior projection. Images were acquired for one hour or until the visualisation of abnormal foci of intake: in this case, lateral and oblique images were acquired for a better localisation of the suspicious area. Some patients were administered furosemide i.v. (0.75 mg/kg). All underwent a follow-up period of 12 months.

Recent findings in auditory research have significantly changed our views of the processes involved in hearing. Novel techniques and new approaches to investigate the mammalian cochlea have expanded our knowledge about the mechanical events occurring at physiologically relevant stimulus intensities. Experiments performed in the apical, low-frequency regions demonstrate that although there is a change in the mechanical responses along the cochlea, the fundamental characteristics are similar across the frequency range. The mechanical responses to sound stimulation exhibit tuning properties comparable to those measured intracellularly or from nerve fibres. Non-linearities in the mechanical responses have now clearly been observed at all cochlear locations. The mechanics of the cochlea are vulnerable, and dramatic changes are seen especially when the sensory hair cells are affected, for example, following acoustic overstimulation or exposure to ototoxic compounds such as furosemide. The results suggest that there is a sharply tuned and vulnerable response related to the hair cells, superimposed on a more robust, broadly tuned response. Studies of the micromechanical behaviour down to the cellular level have demonstrated significant differences radially across the hearing organ and have provided new information on the important mechanical interactions with the tectorial membrane. There is now ample evidence of reverse transduction in the auditory periphery, i.e Desyrel Cost . the cochlea does not only receive and detect mechanical stimuli but can itself produce mechanical motion. Hence, it has been shown that electrical stimulation elicits motion within the cochlea very similar to that evoked by sound. In addition, the presence of acoustically-evoked displacements of the hearing organ have now been demonstrated by several laboratories.

Furosemide is frequently administered intravenously to patients with chronic heart failure. However, use of diuretics may cause neuroendocrine activation and by itself may not consistently afford diuresis. Atrial natriuretic factor (ANF) in pharmacologic doses is a vasodilator and has favorable neuroendocrinologic effects in patients with congestive heart failure. To examine whether exogenous ANF might enhance the effects of acute furosemide injection, we studied 14 patients with chronic stable heart failure and measured the effects of the combination of ANF and furosemide on hemodynamics, neuroendocrine activation, and urine output. Eight patients were randomly assigned to receive placebo plus furosemide (1.3 mg/kg intravenously). Six patients received ANF (2 micrograms/kg intravenously) plus furosemide at the same dose in a double-blind manner. The group receiving placebo plus furosemide exhibited a slight increase in mean arterial pressure (92 to 96 mm Hg; p < 0.03), systemic vascular resistance (1989 to 2271; p = 0.0007), and pulmonary capillary wedge pressure (22 to 24 mm Hg; p < 0.04) from baseline to 10 minutes. The group receiving ANF plus furosemide exhibited no change in mean arterial pressure and systemic vascular resistance from baseline to 10 minutes. Pulmonary capillary wedge pressure and mean pulmonary pressure were unchanged. In the group receiving placebo plus furosemide.(ABSTRACT TRUNCATED AT 250 WORDS)

The ultimate goal of disease treatment is to control the biological system beyond the native regulation to combat pathological process. To maximize the advantage of drugs, we attempted to pharmacologically control the biological system at will, e.g., control multiple hemodynamic variables with multiple cardiovascular drugs. A comprehensive physiological cardiovascular model enabled us to evaluate cardiovascular properties (pump function, vascular resistance, and blood volume) and the feedback control of these properties. In 12 dogs, with dobutamine (5+/-3, nitroprusside (4+/-2, dextran (2+/-2, and furosemide (10 mg in one, 20 mg in one), rapid, sufficient and stable control of pump function, vascular resistance and blood volume resulted in similarly quick and stable control of blood pressure, cardiac output and left atrial pressure in 5+/-7, 7+/-5, and 12+/-10 minutes, respectively. These variables remained stable for 60 minutes (RMS 4+/-3 mmHg, 5+/-2 ml.min(-1).kg(-1), 0.8+/-0.6 mmHg, respectively).

In comparison with placebo, both drugs significantly reduced mean pulmonary capillary wedge pressure following the first dose administration. Only candoxatril significantly reduced pulmonary capillary wedge pressure during exercise on day 0, while both drugs significantly reduced this parameter on day 42. Changes in the remaining hemodynamic parameters were comparable for both drugs relative to placebo. Frusemide significantly increased mean plasma renin activity (days 0 and 42), and the mean aldosterone concentration (day 42) in comparison with placebo, whereas candoxatril caused no significant changes in any of the hormonal parameters assessed.

Seasonal removal efficiency of 16 pharmaceuticals and personal care products was monitored in a wastewater treatment plant in České Budějovice, Czech Republic, over a period of 1 year (total amount of samples, n = 272). The studied compounds included four UV filters, three analgesics/anti-inflammatory drugs and nine anti-hypertensive/cardiovascular drugs. In most cases, elimination of the substances was incomplete, and overall removal rates varied strongly from -38 to 100%. Therefore, it was difficult to establish a general trend for each therapeutic group. Based on the removal efficiencies (REs) over the year, three groups of target compounds were observed. A few compounds (benzophenon-1, valsartan, isradipine and furosemide) were not fully removed, but their REs were greater than 50%. The second group of analytes, consisting of 2-phenylbenzimidazole-5-sulfonic acid, tramadol, sotalol, metoprolol, atenolol and diclofenac, showed a very low RE (lower than 50%). The third group of compounds showed extremely variable RE (benzophenon-3 and benzophenon-4, codeine, verapamil, diltiazem and bisoprolol). There were significant seasonal trends in the observed REs, with reduced efficiencies in colder months.

To determine whether basolateral K channels play an important role in the basal and beta-agonist stimulated ion transport by fetal distal lung epithelium we harvested these cells from fetal rats (20 days gestation, term = 22 days) and studied them in Ussing chambers. Short-circuit current (Isc) fell with basal 3 mM BaCl2 (3.0 +/- 0.2 (+/- SEM) to 2.0 +/- 0.2, n = 18, p < 0.01) without affecting monolayer resistance (R = 693 +/- 57 omega.cm2). Basal quinine sulfate (1 mM) also decreased Isc (3.7 +/- 0.15 to 3.0 +/- 0.10; n = 4, p < 0.01). None of apical BaCl2 (3 mM), apical quinine (1 mM), nor bilaterally applied tetraethylammonium (10 mM), lidocaine (1 mM), or 4-aminopyridine (2 mM) decreased Isc. Cell monolayers treated with basal BaCl2 (3 mM) demonstrated an impaired ability to increase their Isc in response to the beta 2-agonist terbutaline (1 mM). Basal 3 mM BaCl2 also decreased Isc in amiloride (0.1 mM) and furosemide (1 mM) treated monolayers, indicating that barium also affected the previously described amiloride-insensitive Na transport by these cells (n = 8, p < 0.01). Together these experiments suggest that normal basolateral K channel function is required for normal and beta 2-stimulated Na transport in fetal distal lung epithelium.
