It significantly inhibits ovulation and prevents the implantation of fertilized eggs, increases the thickness of cervical mucus, and increases the resistance to sperm penetration, thereby exerting a rapid contraceptive effect.

Extract from the above information

1. Inhibits the redox reaction of amoeba, causing the nitrogen chain of the protozoa to break; 2. When the drug concentration is 1~2mg/L, the histolytica will undergo morphological changes in 6~20 hours and will be killed within 24 hours. When the concentration is 0.2mg/L, the histolytica can be killed within 72 hours; 3. It has a strong effect of killing trichomonas, and its mechanism is unknown; 4. It has a killing effect on anaerobic microorganisms, and its metabolites also have anti-anaerobic effects, inhibiting the synthesis of bacterial deoxyribonucleic acid, thereby interfering with the growth and reproduction of bacteria, and ultimately causing bacterial death; 5. It has a carcinogenic effect on some animals.

Competitively blocks the binding of histamine to H2 receptors. Its inhibitory effect on gastric acid is 5 to 12 times that of cimetidine in terms of moles. Therefore, it is a potent H2 receptor blocker.
