Praziquantel is an anthelmintic medication used to treat various parasitic worm infections. It is prescribed primarily for infections caused by flatworms such as schistosomiasis and liver flukes. The drug works by attaching to the outer surface of parasitic flatworms and interfering with their calcium channels. This interaction leads to spasms and paralysis of the worms, making them vulnerable to the host's immune system. Once the parasites are immobilized or destroyed, the body eliminates them through natural excretory processes. The combined effect of direct toxicity and immune-mediated clearance resolves the infection and alleviates symptoms.

Praziquantel is an anthelmintic medication used primarily to treat infections caused by parasitic flatworms. It is classified as a broad-spectrum agent that targets both intestinal and tissue invasive trematodes such as schistosoma species. The drug's therapeutic role relies on its ability to eliminate these parasites and thereby alleviate the clinical manifestations of schistosomiasis and other helminthiasis. Praziquantel increases the permeability of the parasite tegument to calcium ions, leading to irreversible muscular contraction. The heightened calcium influx disrupts motor function and causes tegument damage, which ultimately results in parasite death. The subsequent degradation of the worm is cleared by the host immune system, providing an effective resolution of the infection.

Praziquantel is generally well tolerated and most people experience few problems. Some individuals may develop mild gastrointestinal symptoms such as abdominal discomfort or nausea. Headache and dizziness are occasionally reported during treatment. Skin reactions such as rash or itching can occur but are usually mild. Fatigue or a general feeling of weakness may be noted in some patients. Rarely, changes in taste or loss of appetite have been documented. Most side effects are temporary and resolve without specific intervention. The drug does not typically cause severe complications when used as prescribed.
