Ranitidine Hydrochloride is a H 2 -receptor blocker used to inhibit gastric acid secretion and to treat stomach and duodenal ulcers. At present, there are several pharmaceutical manufacturers producing capsules in our country, but there are great differences in terms of color, average loading capacity, disintegration time limit, and content determination of the capsule contents. In order to ensure the quality of the product and clinical efficacy, we conducted a study of its dissolution, are reported as follows: 1.
