Praziquin 600mg Tablets PRAZIQUIN-600® contains Praziquantel, a broad-spectrum anthelmintic highly effective against trematodes (flukes) and cestodes (tapeworms). Praziquantel increases the permeability of parasite cell membranes to calcium ions, causing rapid severe contractions and paralysis of the worm's musculature. This is accompanied by rapid vacuolization and focal disintegration of the parasite's tegument, leading to its detachment from host tissues and subsequent clearance. PRAZIQUIN-600® is indicated for the treatment of schistosomiasis (blood fluke infections caused by Schistosoma species), clonorchiasis, opisthorchiasis, and intestinal cestode infections (tapeworms).
