Abstract

The invention provides a Pidotimod solution for intravenous injection, which comprise reactive compound of ((R)-3-[(S)-(5-oxo-2-pyrrolidinyl) carbonyl]-thiazolidine-4-carboxylic acid by a content of 0.4-200mg/ml, solvent for injection and solubilizing agent for injection, the solvent for injection comprises water, non-water solvent or their mixture.

Description

technical field [0001] The invention relates to a pidotimod solution for intravenous injection. Background technique [0002] Pidotimod, namely (R)-3-[(S)-(5-oxo-2-pyrrolidinyl)carbonyl]-thiazolidine-4-carboxylic acid, is a synthetic high-purity Dipeptide is the only immune booster with oral biological activity. In the late 1980s, it was successfully synthesized by the Italian poli chemical company, and it was approved for clinical use in 1993. The drug itself has no antimicrobial activity but is effective in improving the signs and symptoms of infection when combined with antibiotic therapy. [0003] Pidotimod promotes both nonspecific and specific immune responses. It can promote the phagocytic activity of macrophages and neutrophils, improve their chemotaxis, activate natural killer cells; promote the proliferation of lymphocytes caused by mitogens, and make helper T cells (CD4+) and inhibit immune function in low immune function The ratio of...
