Abstract

The invention discloses a Beta-CD inclusion suppository containing rana chensinensis antibacterial peptide for treating gynecological diseases, and also discloses a preparation method thereof. The suppository consists of liposoluble stroma, the antibacterial peptide, Beta-CD, azone and a moderate amount of aqueous mint solution and hardening agent. The suppository is applicable to the prevention or treatment of various directly or indirectly infected gynecological diseases and bacterial and mycotic diseases. An experiment shows that the bactericidal rate can reach more than 99 percent after the suppository acts on staphylococcus aureus, colibacillus and candida albicans for 15min; and an animal experiment shows that the antibacterial peptide suppository cannot cause any irritation on the skin, side effects and drug resistance.
