Problems solved by technology

[0005] Oxymethoniatin is a choleretic drug. At present, the domestic choleretic drug form is single, and it is mainly taken orally. When encountering critically ill patients, patients and doctors have no choice
[0006] Based on the above reasons and clinical needs, it is necessary to develop a choleretic drug that can solve clinical problems for critically ill patients. After years of clinical practice, oxymethyleneamide has been verified for its safety and efficacy. The pharmaceutical regulatory authorities, so far, have not seen the listing of the injection form of oxymethyleneamide

Abstract

The invention provides a nicotinylmethylamide freeze-dried powder preparation for injection and a preparation method thereof. The freeze-dried powder preparation is frozen and dried at low temperature, so the growth of microorganisms and the action of enzyme cannot happen, thereby better maintaining the stability of raw materials. The freeze-dried powder preparation has more convenient storage and transportation, thereby facilitating industrialized production at large scale and convenient clinical use. The freeze-dried powder preparation can be used for intravenous injection or be used for intravenous drip after being added into infusion solutions, can effect soon in the body of a patient, reduce first pass effect of oral medicines in the liver and enhances the bioavailability of medicines in body. The freeze-dried powder preparation can contain active ingredient, such as nicotinylmethylamide, and pharmaceutical excipients and is prepared from the following raw material and pharmaceutical excipients by weight percent: 50-100 nicotinylmethylamide which has content range of 100-1000 mg in the preparation, and 0-50 pharmaceutical excipients.

Description

technical field [0001] The invention relates to a freeze-dried powder preparation of oxymethyleneamine for injection and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Hydroxymethylnicotinamide Hydroxymethylnicotinamide [Nicotinylmethylamide, Oxymethylnicotinamid,] (oxymethylnicotinamide, choleretic)], this product was originally produced in Hungary, Europe, and is the first choice drug recognized in Europe for the treatment of cholecystitis and cholangitis. It also has a good liver protection effect and can also be used as an adjuvant treatment for viral hepatitis. Pharmacokinetic studies have shown that: it can promote the secretion of bile, prevent fatty degeneration of the liver, protect from chemical damage, increase the concentration of salts and bile acids in bile, and its metabolites contain a certain concentration of formaldehyde hydrate ( Formaldehyde hydrate is a hydrogen donor, it plays an intermediate t...
