preparation example 1

[0060] Preparation Example 1: Preparation of Meclofenoxate Hydrochloride Powder for Injection

[0061] (1) Provide sterile meclofenoxate hydrochloride bulk drug;

[0062] (2) pulverize the meclofenoxate hydrochloride bulk drug under aseptic conditions, and monitor the diameter span value of the bulk drug particle in real time during the pulverization process;

[0063] (3) When the span value of the bulk drug granules is less than 5.5 (3.2 in this example, the Dv50 of the powder is 31um), stop pulverizing;

[0064] (4) Under aseptic conditions, the bulk drug obtained in step (3) is divided into glass bottles (250 mg per bottle), sealed, and obtained.

Abstract

The invention belongs to the technical field of medicines, and particularly relates to a method for quickly judging the quality condition of the meclofenoxate hydrochloride powder injection. The method comprises the following steps of (1) providing a meclofenoxate hydrochloride powder injection test sample; (2) determining the particle size and the particle size distribution of the test sample by using a laser scattering granularity distribution instrument and a light scattering method, and calculating Dv10, Dv50 and Dv90 values of test sample particles; (3) calculating the span of the test sample powder by the following formula: Span=(Dv90-Dv10) / Dv50; and (4) determining the quality condition of the meclofenoxate hydrochloride powder injection according to the result of the span value. The invention further relates to a method for preparing the meclofenoxate hydrochloride powder injection by virtue of the span parameter value. According to the method provided by the invention, the quality condition of the meclofenoxate hydrochloride powder injection can be quickly judged, and the obtained product has excellent property when the meclofenoxate hydrochloride powder injection is prepared by virtue of the method.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to a method for quickly judging the quality status of meclofenoxate hydrochloride powder injection for injection, in particular to a method for quickly judging the meclofenoxate hydrochloride powder injection for injection by measuring the particle size distribution of laser diffraction method of quality status. Background technique [0002] Meclofenoxate Hydrochloride was artificially synthesized by Professor Thuillier of the French National Center for Scientific Research in 1957. Its chemical name is 2-(dimethylamino)ethyl p-chlorophenoxyacetate hydrochloride. China has been producing the drug since the 1960s (the trade name used to be cloxatexal). [0003] Clinically, meclofenoxate hydrochloride is a central stimulant drug that has been used for many years. It is mainly used for the treatment of traumatic brain injury coma, neonatal hypoxia, and mental confusion. Children's en...
