We are unexpected in the process of development injection of palonosetron to find that pH is in 3.00～4.00 scopes, is that the injection of adjuvant is more stable than external commercially available injection liquid samples with citric acid, trisodium citrate, glucose.And we do not have hemolytic, blood vessel irritation and anaphylaxis by the pharmacological testing proof according to this prepared injection of filling a prescription.The adjuvant that adopts in the injection prescription of the present invention is citric acid, trisodium citrate, glucose, and has used mannitol and EDTA, citric acid, trisodium citrate, wherein the price comparison costliness of adjuvant mannitol and EDTA in the prescription of external product.Therefore, injection prescription of the present invention is compared with the injection that goes on the market, has reduced supplementary product consumption, especially expensive adjuvant mannitol and EDTA, thus reduced production cost significantly, improve injection stability simultaneously.
Summary of the invention:
Content of the present invention:
The invention provides a kind of more stable injection formulation that contains palonosetron or its water solublity officinal salt, the concentration of palonosetron is 0.01mg/ml～9mg/ml in this injection, preferred 0.25mg/ml.
The officinal salt of palonosetron of the present invention is a hydrochlorate, i.e. palonosetron Hcl, and the injection additives comprise glucose, citric acid, trisodium citrate.
Injection pH scope of the present invention is 3.00～7.00, preferred 3.00～4.00 (not comprising pH4.00).
Another object of the present invention provides the preparation method of stable palonosetron Hcl injection: in this preparation method with palonosetron Hcl and the injection additive preparing of depyrogenation become solution, and regulate pH to 3.00～4.00 (not comprising pH4.00) with 0.1M HCL, the filtration sterilization of 0.22um mixed cellulose ester microporous membrane, embedding, sterilize finished product.
The palonosetron Hcl injection, by palonosetron Hcl and the injection additive preparing of depyrogenation become solution, smart worry, embedding, sterilization make finished product, the gained injection is that 1ml contains palonosetron 0.25mg.Preparation method is: take by weighing recipe quantity injection additives glucose, citric acid, trisodium citrate respectively and add the dissolving of injection water, add an amount of needle-use activated carbon, heated and stirred depyrogenation, filtering decarbonization, in the fine straining liquid of cool to room temperature, add palonosetron Hcl, dissolving is regulated pH to 3.00～4.00 (not comprising pH4.00) with 0.1MHCL, adds water to amount of preparation, gained solution 0.22um mixed cellulose ester microporous membrane fine straining, embedding, sterilization gets product.
Formulating:
1. the solution pH value is regulated
Preparation contains the solution of palonosetron 0.25mg/1ml and injection additives, adopt citric acid and trisodium citrate salt to make the injection pH value keep stable as the injection buffer agent, regulating pH value respectively with 0.1M HCL before the standardize solution is 3.00,3.50,3.80,4.00, add water to the scale standardize solution, fine straining, embedding, sterilization gets product.The injection liquid samples of prepared different pH value is carried out stability test, and the result shows injection of palonosetron equal can retention properties stablizing under high temperature (40 ℃, 60 ℃), high humidity (75%RH, 92%RH), high light condition of pH3.00～4.00.Therefore, we (do not comprise pH4.00) with the pH regulator of injection liquid samples in pH3.00～4.00, have both avoided injection pH scope (4.00～6.00) among the patent WO2004067005, have improved the stability of injection simultaneously.
