Ampyrone, also known as aminopyrine or metamizole, is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Its chemistry involves a pyrazolone ring structure. Ampyrone works by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain signaling. It is commonly used to relieve mild to moderate pain, such as headaches, toothaches, and menstrual cramps, and to reduce fever. Buy high quality Ampyrone from Molsyns Research.
