Abstract

The invention discloses an adrenaline hydrochloride injection and a preparation process thereof. The preparation process comprises the following steps: (1) adding water for injection in a container and inserting CO2 for 15 min, wherein, the volume of the water is 90% of the total volume, and the temperature of the water is less than 30 DEG C; (2) dissolving sodium chloride in proper amount of water for injection having a temperature of below 30 DEG C; (3) dissolving disodium edetate with boiled water for injection; (4) dissolving sodium chloride solution, disodium edetate solution, sodium pyrosulfite and epinephrine respectively in water for injection; (5) measuring the pH value of the solution, regulating the pH value to 3.6-4.0 with 1 mol/L hydrochloric acid, adding water for injection to reach the total amount, and uniformly stirring; (6) filtering; and (7) carrying out aseptic filling and sealing, and inserting N2 in ampoules when filling and sealing; or carrying out filling and sealing according to operating procedures of filling and sealing, inserting N2 in the ampoules when filling and sealing , and carrying out disinfection for 30 min at the temperature of 100 DEG C. The process realizes aseptic production, and products produced by the preparation process satisfy the national medicine quality standards.

Description

【Technical field】 [0001] The invention relates to the field of pharmacy, in particular to chemical drug injections. 【Background technique】 [0002] The Evaluation Center of the State Food and Drug Administration issued the State Food and Drug Administration [2008] No. 7 document in 2008 - "Notice on Issuing Basic Technical Requirements for Chemical Drug Injections and Multi-component Biochemical Drug Injections", which stipulates : Small-volume injections should be terminally sterilized, and it is recommended that the overkill method be preferred (F 0 ≥12), if the product cannot tolerate overkill conditions, the survival probability method (8≤F 0 <12), but it should be ensured that the SAL (sterility assurance level) of the product after sterilization is not greater than 10 -6 . Use other F 0 Processes with terminal sterilization conditions whose value is less than 8 are not approved in principle. If there is sufficient evidence to prove that the terminal sterilizati...
