Spironolacton-ratiopharm
Spironolacton-ratiopharm Uses, Dosage, Side Effects, Food Interaction and all others data.
Spironolacton-ratiopharm is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule. Spironolacton-ratiopharm causes increased amounts of sodium and water to be excreted, while potassium is retained. Spironolacton-ratiopharm acts both as a diuretic and as an antihypertensive drug by this mechanism. It may be given alone or with other diuretic agents which act more proximally in the renal tubule. Aldosterone interacts with a cytoplasmic mineralocorticoid receptor to enhance the expression of the Na+ K+ ATPase and the Na+ channel involved in a Na+ K+transport in the distal tubule . Spironolacton-ratiopharm bind to this mineralcorticoid receptor, blocking the actions of aldosterone on gene expression. Aldosterone is a hormone; its primary function is to retain sodium and excrete potassium in the kidneys.
Originally spironolactone was only studied for its potassium sparing diuretic effect. Spironolacton-ratiopharm competitively inhibits mineralocorticoid receptors in the distal convoluted tubule to promote sodium and water excretion and potassium retention.. Inhibition of this receptor leads to increased renin and aldosterone levels.
Spironolacton-ratiopharm is structurally similar to progesterone and as a result is associated with progestogenic and antiandrogenic effects.

Uses
Spironolacton-ratiopharm is used for Congestive heart failure, Hepatic cirrhosis with ascites and oedema, Nephrotic syndrome, Primary hyperaldosteronism, Essential hypertension, For the treatment of patients with hypokalemia
Spironolacton-ratiopharm is a long-acting aldosterone antagonist. Spironolacton-ratiopharm is a specific pharmacologic antagonist of aldosterone, acting primarily through competitive binding of receptors at the aldosterone dependent sodium-potassium exchange site in the distal convoluted renal tubule. Spironolacton-ratiopharm causes increased amounts of sodium and water to be excreted, while potassium and magnesium is retained.
Spironolacton-ratiopharm is also used to associated treatment for these conditions: Acne, Ascites, Congestive Heart Failure (CHF), Edema, High Blood Pressure (Hypertension), Hypokalemia, Idiopathic Hirsutism, Nephrotic Syndrome, Primary Hyperaldosteronism, Secondary hyperaldosteronism, Chronic heart failure with reduced ejection fraction (NYHA Class III), Chronic heart failure with reduced ejection fraction (NYHA Class IV), Idiopathic hyperaldosteronism
How Spironolacton-ratiopharm works
Spironolacton-ratiopharm competitively inhibits aldosterone dependant sodium potassium exchange channels in the distal convoluted tubule. This action leads to increased sodium and water excretion, but more potassium retention. The increased excretion of water leads to diuretic and also antihypertensive effects.
Dosage
Spironolacton-ratiopharm dosage
Edema in adults (congestive heart failure, hepatic cirrhosis, or nephrotic syndrome): An initial daily dosage of 100 mg of Spironolacton-ratiopharm administered in either single or divided doses is recommended, but may range from 25 to 200 mg daily. Combined therapy with other diuretics is indicated when more rapid diuresis is desired.
Primary hyperaldosteronism: After the diagnosis of hyperaldosteronism has been established, Spironolacton-ratiopharm may be administered in doses of 100 to 400 mg daily in preparation for surgery. For patients who are considered unsuitable for surgery, Spironolacton-ratiopharm may be employed for long-term maintenance therapy at the lowest effective dosage determined for the individual patient.
Essential hypertension: For adults, an initial daily dosage of 50 to 100 mg of Spironolacton-ratiopharm administered in either single or divided doses is recommended.
Hypokalemia: Spironolacton-ratiopharm in a dosage ranging from 25 mg to 100 mg daily is useful in treating a diuretic-induced hypokalemia.
Side Effects
Gynaecomastia may develop in association with the use of Spironolacton-ratiopharm. Other adverse reactions are: GI symptoms including cramping and diarrhoea, drowsiness, lethargy, headache, urticaria, mental confusion, impotence, irregular menses or amenorrhoea and post-menopausal bleeding.
Toxicity
Patients experiencing an overdose may present with drowsiness, mental confusion, maculopapular or erythematous rash, nausea, vomiting, dizziness, or diarrhea. Vomiting is generally induced or a gastric lavage is performed. Supportive treatment involves maintining hydration, electrolyte balance, and vital functions.
The oral LD50 in mice, rats, and rabbits is >1g/kg.
Spironolacton-ratiopharm should be avoided in pregnancy due to reports of feminization of male fetuses in animal studies. Active metabolites of spironolactone are present in breast milk and levels that are likely inconsequential, though the long term effects have not been studied.
In animal studies, spironolactone slowed follicle development, ovulation, and implantation. Spironolacton-ratiopharm increased the incidence of benign adenomas in the testes of male rats, benign uterine endometrial stromal polyps in female rats, and thyroid follicular cell adenomas in both sexes of rats. Spironolacton-ratiopharm and canrenone are generally not considered to be mutagenic in tests but canrenone occasionally tests positive for mutagenicity with metabolic activation and spironolactone has occasionally tested inconclusive though slightly positive for mutagenicity.
Precaution
All patients receiving diuretic therapy should be observed for evidence of fluid or electrolyte imbalance. Hyperkalemia may occur in patients with impaired renal function or excessive potassium intake and can cause cardiac irregularities, which may be fatal.
Interaction
ACE inhibitors: Concomitant administration of ACE inhibitors with potassium-sparing diuretics has been associated with severe hyperkalemia.
Alcohol, barbiturates, or narcotics: Potentiation of orthostatic hypotension may occur.
Corticosteroids, ACTH: Intensified electrolyte depletion, particularly hypokalemia, may occur.
Lithium: Lithium generally should not be given with diuretics. Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity.
Digoxin: Spironolacton-ratiopharm has been shown to increase the half-life of digoxin.
Food Interaction
- Avoid alcohol.
- Avoid potassium-containing products. Potassium products increase the risk of hyperkalemia.
- Take with or without food. Food increases the bioavailability of spironolactone by nearly 100%. It should be taken at a consistent time in regards to food.
Spironolacton-ratiopharm 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.
