Abstract

The invention discloses benazepril hydrochloride tablets for cats and dogs and a preparation method for the benazepril hydrochloride tablets. The benazepril hydrochloride tablets consist of the following components in percentage by mass: 0.1 to 2 percent of benazepril, 30 to 70 percent of lactose, 10 to 50 percent of microcrystalline cellulose, 0.5 to 10 percent of hydroxypropyl cellulose, 0.5 to 9 percent of cross-linked polyvinylpyrrolidone, 1 to 10 percent of polyvinylpyrrolidone K30, 0.1 to 1 percent of aspartame and 0.2 to 1.5 percent of magnesium stearate. After being taken, the tablets can be quickly disintegrated, and active ingredients can be quickly dissolved; and the tablets have high palatability, and small irritation on intestines and stomach.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a benazepril hydrochloride tablet for cats and dogs and a preparation method thereof. Background technique [0002] Heart disease in pets, especially dogs and cats, is not uncommon in small animal clinics. With the increasing number of elderly dogs and cats, the incidence of heart disease is on the rise, but the diagnostic techniques and treatment methods are still relatively backward. [0003] At present, drugs commonly used in the treatment of heart disease include renin-angiotensin-aldosterone system blockers, angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB) and aldosterone Receptor antagonists, sympathetic blockers, etc. ACEI is widely used in human medicine, and the effect is more significant. However, in veterinary clinics, there is no product specifically for dogs and cats, and most of them are used for human medicine. It is illegal to tra...
