Abstract

The invention discloses a Naloxone hydrochloride injection and powder injection, and the process for preparation, wherein middle aperture fiber film hyperfiltration technology is employed to remove the impurities, thus diminishing the damage of main medicaments and improving the quality of products.

Description

technical field [0001] The invention relates to an opioid receptor pure antagonist, a drug having completely opposite pharmacological effects to morphine-naloxone hydrochloride injection dosage form and a preparation method thereof. Background technique [0002] Naloxone hydrochloride (Naloxone hydrochloride) is a specific opioid receptor antagonist, which does not stimulate the receptor itself, but has a greater affinity with the receptor than morphine and enkephalin, and can competitively block or replace opioids and endogenous substances. The combination of the derived opioid peptide and the receptor relieves the poisoning of morphine drugs, antagonizes the inhibition of the respiratory center, and has a wake-up effect. The Ministry of Health of my country approved its small water injection (specification: 1ml: 0.4mg) to go on the market in 1990. It is used for intramuscular injection or intravenous injection to relieve respiratory depression, awakeni...
