Zoquine

Zoquine is an antimalarial drug that is used to prevent or treat malaria. It is a synthetic mescaline-related compound classified as a 4-quinolinemethanol group. It is available in oral pill form or as an injectable solution. It is especially used to prevent and treat malaria caused by Plasmodium falciparum, the parasite that causes the most severe form of malaria in humans.

Zoquine is used to prevent and treat malaria caused by Plasmodium falciparum. It is also used to prevent malaria in travelers to areas where the disease is prevalent. Zoquine can be used to treat individuals who have already been infected with the parasite.

Mechanism of Action

Zoquine works by preventing the growth of Plasmodium inside human red blood cells, which reduces the spread of the disease. Zoquine also interferes with the metabolic processes of the parasites, preventing them from forming important enzymes and proteins required for their survival.

How Long Does it Take to Work?

Zoquine usually takes effect within 2 hours of ingestion and can remain effective for up to 4 weeks. The risk of malaria is significantly reduced if the drug is taken every 7 days for at least 10 days before entering an endemic area. Prolonged use may also reduce the risk of pneumonitis due to Plasmodium knowlesi.
