Abstract

The invention provides a pipemidic acid pharmaceutical composition which is characterized by being prepared from, by weight, 20-70% of pipemidic acid and 30-80% of pharmaceutic adjuvants. According to the pharmaceutical properties of pipemidic acid, the formula is scientific, the dissolving and absorbing speed of the medicine is increased, the composition is safe and non-toxic, medicine compliance of a patient is good, and the effect is remarkable.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a pipemidic acid pharmaceutical composition and a preparation method thereof. Background technique [0002] Pipemidic acid, English name: Pipemidic Acid, Chinese alias piperic acid, English alias Doliol, PiperamicAcid, Pipram, this product is light yellow or light yellow crystalline powder; odorless, bitter taste. This product is slightly soluble in methanol or dimethylformamide, very slightly soluble in water or chloroform, insoluble in ethanol, ether or benzene; easily soluble in sodium hydroxide test solution or glacial acetic acid. The melting point of this product is 251-256°C, and it decomposes at the same time when it melts. It is clinically used as an enema liquid for treating diarrhea. [0003] Dysentery, enteritis, ulcerative colitis, etc. are diseases with diarrhea as the main symptom. The treatment of these diseases is mainly based on oral, intramuscular i...
