Ranitidine Hydrochloride Usage And Synthesis
Background and overviewRanitidine Hydrochloride (RHCl) is a kind of histamine H2 receptor antagonist. Since its listing in 1981, ranitidine hydrochloride has been widely used in nearly one hundred countries in the world, including China. It is clinically used for the treatment of duodenal ulcer, reflux esophagitis and Zollinger-Ellison syndrome. It is also used for the prevention of gastrointestinal bleeding caused by stress ulcer and recurrent hemorrhage of peptic ulcer. In recent decade, through the combination of ranitidine and other drugs, it has found that it has high efficiency and remarkable features in the treatment of Helicobacter pylori-positive duodenal ulcer, urticaria and post-cerebral hemorrhage stress ulcer with better efficacy than other similar drugs. Owing to its rapid effect, good potency and low price, ranitidine hydrochloride plays an important role in the anti-ulcer drug market today. Therefore, strict quality control plays important roles in guiding patients with reasonable, safe medication.
Pharmacological effectsThis product is a H2 receptor inhibitor, being capable of inhibiting the gastric acid secretion. After oral administration, it is absorbed through the gastrointestinal tract quickly. Synthetic route [4]
The intermediates (3) and (5) were synthesized as follows. The intermediates (3) and (5) were then reacted to produce (6) ranitidine. The (6) is subject to purification and salt formation to generate ranitidine hydrochloride, as shown:
PharmacokineticsAfter oral administration, it is absorbed rapidly from the gastrointestinal tract with a bioavailability (F) of about 50% and peak plasma concentration (tmax) reaching within 1 to 2 hours. Plasma protein binding rate is 15% ± 3%; effective blood concentration is 100ng / ml, widely distributed in the body with the apparent volume of distribution (Vd) of 1.1 ~ 1.9L / Kg. It can penetrate through the blood - brain barrier with the drug concentration in cerebrospinal fluid being 1/30 ~ 1 / 20 of blood concentration. 30% is subject to liver metabolism with the metabolites including N-oxide, S-oxide and demethylation metabolites. 50% of the prototype is subject to urine excretion through kidney. Half-life (t1 / 2) is 2 to 3 hours, which is similar to cimetidine. Renal failure causes corresponding increase in the half-life. The goods can be transplanted via the placenta with the milk concentration being higher than the plasma concentration of drugs.
IndicationsFor the treatment of duodenal ulcer, gastric ulcer, reflux esophagitis, Zollinger-Ellison syndrome and other high acid secretion disorders.
