Introduction
Rantolex Suspension is a liquid formulation of ranitidine from Astemax Biotech, used for effective acid suppression in pediatric and adult GERD management.
Composition
Each 5 ml of this mint-flavored syrup contains Ranitidine 75 mg (as hydrochloride), with a palatable base including sorbitol, glycerol, and preservatives for stability in 100 ml bottles.
Uses
It treats heartburn, acid indigestion, peptic ulcers, and gastroesophageal reflux, especially in children over 3 or patients preferring liquid form, by healing mucosal damage and preventing relapse.
Mechanism
Ranitidine competitively blocks H2 receptors on parietal cells, reducing gastric acid secretion by up to 70% for 12 hours, promoting faster ulcer healing without affecting gastrin levels.
