Quinine dihydrochloride, 250mg

Quinine dihydrochloride is an antiparasitic used to treat malaria and is particularly important for managing malaria during the first trimester of pregnancy. It inhibits Slo3 (KCa 5.1) channel, which are a significant part of the mammalian KSper (sperm potassium conductance), by binding to hydrophobic side chains located at the intracellular region of the channel pore.
