Tamar & Pharez Furosemide

Tamar & Pharez Furosemide Uses, Dosage, Side Effects, Food Interaction and all others data.

Tamar & Pharez Furosemide is a monosulphonyl diuretic. It is an effective diuretic that retains its activity even in low glomerular filtration rate (GFR). Tamar & Pharez Furosemide has a distinctive action on renal tubular function. It affects a peak diuresis far greater than that observed with other agents. Other features are (I) prompt onset of action (II) inhibition of sodium and chloride transport in the ascending limb of the loop of Henle and (III) independence of their action from acid-base balance changes. Tamar & Pharez Furosemide acts primarily to inhibit electrolyte reabsorption in the thick ascending limb of the loop of Henle. Tamar & Pharez Furosemide is readily absorbed from the gastrointestinal tract and considerable proportions are bound to plasma proteins. It is rapidly excreted in the urine. With an hour after intravenous injection, its effect is evident in about 5 minutes and last for about 2 hours.

Tamar & Pharez Furosemide manages hypertension and edema associated with congestive heart failure, cirrhosis, and renal disease, including the nephrotic syndrome. Tamar & Pharez Furosemide is a potent loop diuretic that works to increase the excretion of Na+ and water by the kidneys by inhibiting their reabsorption from the proximal and distal tubules, as well as the loop of Henle. It works directly acts on the cells of the nephron and indirectly modifies the content of the renal filtrate. Ultimately, furosemide increases the urine output by the kidney. Protein-bound furosemide is delivered to its site of action in the kidneys and secreted via active secretion by nonspecific organic transporters expressed at the luminal site of action.

Following oral administration, the onset of the diuretic effect is about 1 and 1.5 hours , and the peak effect is reached within the first 2 hours. The duration of effect following oral administration is about 4-6 hours but may last up to 8 hours. Following intravenous administration, the onset of effect is within 5 minutes, and the peak effect is reached within 30 minutes. The duration of action following intravenous administration is approximately 2 hours. Following intramuscular administration, the onset of action is somewhat delayed.

How Tamar & Pharez Furosemide works

Tamar & Pharez Furosemide promotes diuresis by blocking tubular reabsorption of sodium and chloride in the proximal and distal tubules, as well as in the thick ascending loop of Henle. This diuretic effect is achieved through the competitive inhibition of sodium-potassium-chloride cotransporters (NKCC2) expressed along these tubules in the nephron, preventing the transport of sodium ions from the lumenal side into the basolateral side for reabsorption. This inhibition results in increased excretion of water along with sodium, chloride, magnesium, calcium, hydrogen, and potassium ions. As with other loop diuretics, furosemide decreases the excretion of uric acid.

Tamar & Pharez Furosemide exerts direct vasodilatory effects, which results in its therapeutic effectiveness in the treatment of acute pulmonary edema. Vasodilation leads to reduced responsiveness to vasoconstrictors, such as angiotensin II and noradrenaline, and decreased production of endogenous natriuretic hormones with vasoconstricting properties. It also leads to increased production of prostaglandins with vasodilating properties. Tamar & Pharez Furosemide may also open potassium channels in resistance arteries. The main mechanism of action of furosemide is independent of its inhibitory effect on carbonic anhydrase and aldosterone.

Dosage

Tamar & Pharez Furosemide dosage

Tablet-

Edema:

  • Adults: The initial adult dose is 40 mg daily, reduced to 20 mg daily or 40 mg on alternate days. In some patients daily doses of 80 mg or higher (given in divided doses) may be required. The individually determined single dose should then be given once or twice daily (eg, at 8 am and 2 pm). For resistant edema, 80-120 mg daily. In patients with clinically severe edematous states the dose of furosemide may be carefully titrated up to 600 mg/day. When doses exceeding 80 mg/day are given for prolonged periods, careful clinical observation and laboratory monitoring are particularly advisable.
  • Neonate: 0.5-2 mg/kg every 12-24 hours (every 24 hours if postmenstrual age under 31 weeks).
  • Child 1 month-12 years: 0.5-2 mg/kg 2-3 times daily (every 24 hours if postmenstrual age less than 31 weeks); higher doses may be required in resistant edema; max. 12 mg/kg daily, not to exceed 80 mg daily.
  • Child 12-18 years: 20-40 mg daily, increased in resistant edema to 80-120 mg daily.
  • Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.

Hypertension:

  • Adults: The usual initial dose of furosemide for hypertension is 80 mg, usually divided into 40 mg twice a day. Dosage should then be adjusted according to response. If response is not satisfactory, add other antihypertensive agents. Children: The usual dose is 1-3 mg/kg body weight daily up to a maximum dose of 40 mg/day.
  • Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.

Injection-

Edema:

  • Adults: Doses of 20-50 mg intramuscularly or intravenously may be given initially. If larger doses are required, they should be given increasing by 20 mg increments and not given more often than every two hours. If doses greater than 50 mg are required it is recommended that they should be given by slow intravenous infusion. The recommended maximum daily dose of furosemide administration is 1,500 mg.
  • Neonate: 0.5-1 mg/kg every 12-24 hours (every 24 hours ifpostmenstrual age under 31 weeks).
  • Child 1 month-12 years: 0.5-1 mg/kg repeated every 8 hours as necessary; maximum 2 mg/kg (max. 40 mg) every 8 hours.
  • Child 12-18 years: 20-40 mg repeated every 8 hours as necessary; higher doses may be required in resistant cases.
  • Child 1 month-18 years: By continuous intravenous infusion:0.1-2 mg/kg/hour (following cardiac surgery, initially 100 micrograms/kg/hour, doubled every 2 hours until urine output exceeds 1 mL/kg/hour).
  • Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.

Hypertension:

  • Adults: Doses of 20 to 50 mg intramuscularly or intravenously may be given initially. If larger doses are required, they should be given increasing by 20 mg increments and not given more often than every two hours.
  • If doses greater than 50 mg are required it is recommended that they should be given by slow intravenous infusion. The recommended maximum daily dose of furosemide administration is 1,500 mg. Children: Parenteral doses for children range from 0.5-1.5 mg/kg body weight daily up to a maximum total daily dose of 20 mg.
  • Elderly: In the elderly furosemide is generally eliminated more slowly. Dosage should be titrated until the required response is achieved.

Tablet: May be taken with or without food. May be taken with meals to reduce GI discomfort.

Injection: Injection should be administered in children by slow intravenous injection

Side Effects

As with other diuretics, electrolytes and water balance may be disturbed as a result of diuresis of prolonged therapy. Prolonged use can produce alkalosis. It may also cause uric acid retention and may rarely produce acute gout. Tamar & Pharez Furosemide may provoke hyperglycemia and glycosuria.

Toxicity

Clinical consequences from overdose depend on the extent of electrolyte and fluid loss and include dehydration, blood volume reduction, hypotension, electrolyte imbalance, hypokalemia, hypochloremic alkalosis, hemoconcentration, cardiac arrhythmias (including A-V block and ventricular fibrillation). Symptoms of overdose include acute renal failure, thrombosis, delirious states, flaccid paralysis, apathy and confusion. In cirrhotic patients, overdosage might precipitate hepatic coma.

In rats, the oral LD50, intraperitoneal LD50, and subcutaneous LD50 is 2600 mg/kg, 800 mg/kg, and 4600 mg/kg, respectively. The Lowest published toxic dose (TDLo) in a female is 6250 μg/kg.

Precaution

Patients with prostatic hypertrophy or impairment of micturition have an increased risk of developing acute retention. A marked fall in blood pressure may be seen when ACE inhibitors are added to furosemide therapy. The toxic effects of nephrotoxic antibiotics may be increased by concomitant administration of potent diuretics such furosemide.

Interaction

A marked fall in blood pressure may be seen when ACE inhibitors are added to furosemide therapy. Serum lithium levels may be increased when lithium is given concomitantly with furosemide. The toxic effects of nephrotoxic antibiotics may be increased by concomitant administration of potent diuretics such as furosemide.

Food Interaction

  • Avoid excessive or chronic alcohol consumption. Alcohol increases the risk of orthostatic hypotension.
  • Avoid natural licorice. Avoid licorice in large amounts, as it may lead to hypokalemia.
  • Increase consumption of potassium-rich foods. This medication may cause potassium depletion. Foods containing potassium include bananas and orange juice.

Tamar & Pharez Furosemide Alcohol interaction

[Moderate]

Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation.

Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

Caution and close monitoring for development of hypotension is advised during coadministration of these agents.

Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs.

Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Volume of Distribution

The volume of distribution following intravenous administration of 40 mg furosemide were 0.181 L/kg in healthy subjects and 0.140 L/kg in patients with heart failure.

Elimination Route

Following oral administration, furosemide is absorbed from the gastrointestinal tract. It displays variable bioavailability from oral dosage forms, ranging from 10 to 90%. The oral bioavailability of furosemide from oral tablets or oral solution is about 64% and 60%, respectively, of that from an intravenous injection of the drug.

Half Life

The half-life from the dose of 40 mg furosemide was 4 hours following oral administration and 4.5 hours following intravenous administration. The terminal half-life of furosemide is approximately 2 hours following parenteral administration. The terminal half-life may be increased up to 24 hours in patients with severe renal failure.

Clearance

Following intravenous administration of 400 mg furosemide, the plasma clearance was 1.23 mL/kg/min in patients with heart failure and 2.34 mL/kg/min in healthy subjects, respectively.

Elimination Route

The kidneys are responsible for 85% of total furosemide total clearance, where about 43% of the drug undergoes renal excretion. Significantly more furosemide is excreted in urine following the I.V. injection than after the tablet or oral solution. Approximately 50% of the furosemide load is excreted unchanged in urine, and the rest is metabolized into glucuronide in the kidney.

Pregnancy & Breastfeeding use

Pregnancy Category C. Frusemide should be cautiously used in cardiogenic shock complicated by pulmonary oedema and in the first trimester of pregnancy. Blood pressure and pulse during rapid diuresis should be monitored. Caution should be observed in patients liable to electrolyte deficiency. In case of nursing mother, Frusemide may inhibit lactation because it may pass into breast milk. In that case it should be used with caution.

Contraindication

Tamar & Pharez Furosemide is contraindicated in anuria, electrolyte deficiency and pre-comatose states associated with liver cirrhosis. Hypersensitivity to furosemide or sulphonamides.

Acute Overdose

Symptoms: Dehydration, electrolyte disturbances, hypotension and cardiac toxicity, hypochloremic alkalosis, hypokalaemia, blood volume reduction.

Management: Symptomatic and supportive treatment. Replacement of excessive fluid and electrolyte losses. Ensure adequate drainage in patients with urinary bladder outlet obstruction (e.g. prostatic hypertrophy). Treat hypotension with appropriate IV fluids.

Storage Condition

Store between 15-30°C. Protect from light.
