Abstract

A dripping pile of corydalis B hydrochloride is prepared through superfine pulverizing and the conventional steps for preparing dripping pills. Its advantages are high disintegrating and dissolving speed, quickly taking its effect and low cost.

Description

technical field [0001] The invention relates to a medicine preparation and a preparation method thereof, in particular to tetrahydropalmatine sulfate dripping pills and a preparation method thereof. Background technique [0002] Tetrahydropalmatine sulfate has analgesic, sedative, hypnotic and stable effects. The analgesic effect is not as good as pethidine, but stronger than general antipyretic analgesics. The analgesic effect occurs 10-30 minutes after taking it and lasts for 2-5 hours. It has a good effect on the dull pain of gastrointestinal and hepatobiliary system diseases, and has a poor analgesic effect on trauma, postoperative pain or advanced cancer. The therapeutic dose is non-addictive. The oral preparations currently on the market are only Tetrahydropalmatine Sulfate Tablets, which are clinically used for visceral pain and menstrual pain caused by digestive system diseases, postpartum abdominal pain, headache and insomnia.
