Abstract

The invention discloses a cefotiam hydrochloride pharmaceutical composition for injection and a preparation method thereof. The cefotiam hydrochloride pharmaceutical composition for injection comprises the following components in parts by weight: 500 parts of cefotiam hydrochloride, (121-x) parts of anhydrous sodium bicarbonate and 2x parts of anhydrous sodium carbonate, wherein x is not less than 1 and not more than 120. The cefotiam hydrochloride pharmaceutical composition for injection disclosed by the invention can be used for solving the problems in the prior art that CO2 partial pressure in blood is extremely low and pH stability is low after cefotiam hydrochloride injection is injected to a human body and the problem that intoxication is easily caused after long-term use of the cefotiam hydrochloride injection.
