Abstract

The present invention discloses a preparation technology of captopril tablets. The tablets are prepared from the following components in weight percentages: captopril, a filler, a disintegrant, a lubricant and an adhesive. Weighing, screening and mixing are conducted, compressable auxiliary materials are used and direct tableting is conducted to prepare the captopril tablets. The preparation technology reduces the content of hydrolyzed impurity captopril disulfide in the captopril, improves the dissolution rate, and is simple, cost-saving, good in stability, etc.

Description

technical field [0001] The invention belongs to the field of captopril preparations, in particular to a preparation process of captopril tablets. Background technique [0002] As we all know, cardiovascular disease has become the biggest enemy that threatens human life and health, and hypertension is the chief culprit in cardiovascular disease. The advent of captopril, the first angiotensin-converting enzyme (ACE) inhibitor, is undoubtedly a milestone event in the history of human combat against hypertension. Captopril is a best-selling drug that has been approved for use in nearly 80 countries around the world. It is also the first ACE-I to come out, and it is currently the most widely used and orally effective ACE-I. It is widely used clinically for hypertension and heart failure, especially for renal hypertension. It is also suitable for the treatment of hypertensive patients with diabetes, hyperlipidemia, bronchial asthma, left ventricular hypertrophy and heart failu...
