Ranisan 75 mg
Ranitidine hydrochloride 84 mg in 1 coated tablet
H2-receptor antagonists (ATC code: A02BA02)
Short and symptomatic treatment of the signs of heartburn, gastric hyperacidity and nausea.
Ranitidine, a histamine H2-receptor antagonist, inhibits diurnal and nocturnal gastric secretion, both basal and stimulated, thus causing a decrease in the acidity and volume of gastric juice. If administered orally, ranitidine is absorbed very rapidly and the maximum plasma level is reached within 1–3 hours. The food does not affect the biological availability of ranitidine. Biological half-life ranges between 2–3 hours, in renal insufficiency it is prolonged.
Pharmaceutical formFilm-coated tablets
Posology and method of administration
One tablet is taken in case of problems; two tablets may be taken over a 24-hour period. Total duration of treatment without consulting a physician should not exceed 5 days. Tablets are taken unchewed, with or without food and with plenty of fluids.
Hypersensitivity to ranitidine or the excipients. Administer to pregnant and breast-feeding women only if clearly needed.
Ranitidine influences cytochrome P-450 so slightly, practically no drug interactions on this basis occur. By reducing the acidity of the contents of the stomach, ranitidine may reduce ketoconazole absorption. Concomitant administration of ranitidine with high doses of sucralfate (2 g) may reduce ranitidine absorption.
The following may appear: headache, dizziness, confusion in elderly people, nausea, constipation, diarrhoea, blurred vision, impotence, hair loss, allergic skin reactions, raised levels of liver enzymes, leukocytopenia and thrombocytopenia. In very rare cases, heart rhythm disorders were reported.
