Abstract
The invention belongs to the technical field of medicines, and discloses a medicine composition containing metronidazole. The medicine composition comprises metronidazole, carbomer 934, propylene glycol, a solubilizer, a pH regulator and a complexing agent. The invention also discloses another medicine composition containing metronidazole. Another medicine composition disclosed by the invention is prepared from the following components in parts by weight: 35-45 parts of metronidazole, 40-50 parts of carbomer 934, 100-120 parts of propylene glycol, a solubilizer and 15-20 parts of a pH regulator, namely sodium citrate and L-arginine. Tests indicate that vaginal gel prepared from the medicine composition has better safety and stability.
Description
technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a pharmaceutical composition containing metronidazole.
