Ranitidine is an oral medication that belongs to the family of drugs known as histamine-2 receptor antagonists. It is used to treat conditions such as acid reflux, GORD, heartburn and peptic ulcers. It works by preventing certain cells within the stomach lining from producing acid, allowing peptic ulcers to heal and prevent any reflux towards the respiratory tract. It is recommended that the patient take a twice-daily dose regularly for therapeutic results to be at its most effective, ideally in the morning and evening.
