Dosage and administration (summary)

DOSAGE AND ADMINISTRATION Active Duodenal Ulcer: The current recommended adult oral dosage of Ranitidine Tablets for duodenal ulcer is 150 mg twice daily. An alternative dosage of 300 mg once daily after the evening meal or at bedtime can be used for patients in whom dosing convenience is important. The advantages of one treatment regimen compared with the other in a particular patient population have yet to be demonstrated (see Clinical Trials: Active Duodenal Ulcer ). Smaller doses have been shown to be equally effective in inhibiting gastric acid secretion in US studies, and several foreign trials have shown that 100 mg twice daily is as effective as the 150 mg dose.

Contraindications

CONTRAINDICATIONS Ranitidine Tablets are contraindicated for patients known to have hypersensitivity to the drug or any of the ingredients (see PRECAUTIONS ).
