Problems solved by technology

[0015] The invention of US2011293717 provides a moxifloxacin hydrochloride pharmaceutical composition prepared by a dry method. The coating agent is a mixture of low-viscosity hypromellose, titanium dioxide, polyethylene glycol and iron oxide. It is found in practice that the tablet core Prepared by dry method, the process is relatively complicated, difficult to control, and poor reproducibility. In the coating agent, hypromellose is coated with phamacoat603, and the coating film is incomplete and poor in uniformity.
[0016] Although the prior art discloses the prescription composition and preparation method of moxifloxacin hydrochloride pharmaceutical compositions in various dosage forms, it has been found in practice that due to the poor water solubility of moxifloxacin hydrochloride and the large weight ratio in the pharmaceutical composition, especially tablets The pharmaceutical composition of the dosage form is coated with a low-viscosity HPMC and polyethylene glycol, or Opadry, which often has uneven coating film, long coating time, poor dissolution effect or tablet drug Problems such as poor composition stability

Abstract

The invention provides a moxifloxacin hydrochloride pharmaceutical composition and preparation method thereof. The invention is characterized in that: tablet core is prepared by moxifloxacin hydrochloride, more than one excipient and a coating material, wherein, the weight of moxifloxacin hydrochloride is 60-70% of that of the tablet core, and the weight of excipients is 30-40% of that of the tablet core, and the weight of the coating material which is used for coating the tablet core and is composed of hypromellose with two or more than two viscosities is 1.0-4.0% of that of the pharmaceutical composition tablet core, and the weight ratio between hypromellose with viscosity of 40-120mPa.s and hypromellose with viscosity of 2.5-1.8mPa.s is 1:5-1:2. The pharmaceutical composition has the advantages of good stability, simple preparation technology and easy reproduction; the preparation method is suitable for industrial production.

Description

technical field [0001] The invention relates to a pharmaceutical composition and a preparation method thereof in the technical field of medicine, in particular to a moxifloxacin hydrochloride pharmaceutical composition and a preparation method thereof. Background technique [0002] Moxifloxacin Hydrochloride, English name: MoxifloxacinHydrochloride, is light yellow to yellow crystalline powder, slightly soluble in water and methanol, slightly soluble in ethanol, almost insoluble in acetone, the structural formula is as follows: [0003] [0004] Moxifloxacin hydrochloride is the fourth-generation broad-spectrum 8-methoxyfluoroquinolone antibacterial drug. It is an antibacterial drug widely used in clinical practice in recent years, and it is also a relatively new class of synthetic antibacterial drug. Moxifloxacin hydrochloride can directly fight Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis, which is different from the currently used fluoroqu...
