Problems solved by technology

The disadvantage of the above method: during preparation, coenzyme A needs to be added to the solution of mannitol, lactose, cysteine ​​hydrochloride or mannitol, calcium gluconate, cysteine ​​hydrochloride, so that coenzyme A is always in a non-dry state, The product is easy to degrade and the potency content is reduced
It is still in a non-drying state during the freeze-drying process, and the weight loss on drying after freeze-drying is high, which makes it easy to degrade during storage, and the titer content decreases, which ultimately makes the product quality unstable.

Abstract

The invention discloses a coenzyme A freeze drying agent and a preparation method thereof, which comprise product prescription, stable liquid preparation, injection preparation, aseptic filtration, filling, freeze drying, capping, leakage detecting and lamp detection packing, and uses coenzyme A as main effective components, and uses optimized skeleton agent mannitol, reductant cysteine hydrochloride, stabilizer gelatin and lactose and the like as pharmaceutic adjuvants to improve stability of drugs. The coenzyme A freeze drying agent and the preparation method thereof reduce water content of finished products below 0.6% by optimizing freeze drying process, and enables coenzyme A for injection to be steadier. The coenzyme A freeze drying agent and the preparation method thereof solve the stability problem of the coenzyme A, improve product yield of the coenzyme A, and have the advantage of simple process, steady quality and high product yield compared with existing freeze drying agents.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a freeze-dried preparation of coenzyme A and a preparation method thereof. Background technique [0002] Coenzyme A is composed of pantothenic acid, cysteine, adenosine triphosphate in Mg 2+ Synthesized by a series of enzyme-catalyzed reactions with the participation of coenzyme A, the active group in the coenzyme A molecule is a sulfhydryl group, which can form a sulfur enzyme with an acid group. The degradation process of coenzyme A in the body is basically opposite to the synthesis process. The degradation products pantethein and pantothenic acid can enter the synthesis pathway of coenzyme A and be converted into coenzyme A to maintain a relatively constant level of coenzyme A in the body. [0003] Coenzyme A deficiency in humans can cause depression, anxiety, irritability, loss of appetite, fatigue, recurrent respiratory infections, numbness, muscle wea...
