Problems solved by technology

However, this method can only cover the bitter taste of the active ingredient in the process of oral chewing, and cannot solve the problem that the neutralization reaction between the alkalinizing agent and gastric acid leads to a decrease in the solubility of telmisartan and low bioavailability when it is applied to the preparation of telmisartan

Abstract

The invention relates to a telmisartan flavor chewable tablet. The telmisartan flavor chewable tablet is prepared from, by weight, 10-30% of telmisartan, 20-35% of a diluent, 30-45% of a filler, 1-10%of an alkalizer, 1-10% of a disintegrating agent, 1-5% of an adhesive, 5-20% of a flavoring agent and 2-5% of a coating agent. By means of a coating material, granules with the telmisartan and alkalizer are coated through a fluidized bed, the solubility and bioavailability of the telmisartan in the intestinal environment are improved, and the bitter taste and oral mucosa irritation caused when adog chews the telmisartan tablet are effectively removed. The beef flavor telmisartan chewable tablet is high in palatability, and the medicine compliance of a pet is improved.

Description

technical field [0001] The invention belongs to the field of veterinary pharmaceutical preparations, in particular to a telmisartan flavored chewable tablet and a preparation method thereof. Background technique [0002] Domestic companion pets have good living conditions and lack of sufficient exercise, and often suffer from overnutrition and obesity. The resulting cardiovascular diseases such as hypertension, heart disease and kidney disease have become common clinical diseases in elderly pets. Congestive heart failure and chronic kidney disease in pet dogs and cats are both progressive and irreversible chronic diseases. Once the disease occurs, it means permanent pathological damage to the heart and kidneys. After the elderly pet dogs and cats get sick, if they are not treated in time, various complications will occur, resulting in a serious decline in the quality of life and a greatly shortened life span, which will cause great economic and emotional pressure on pet owne...
