What is Metamizole Sodium Monohydrate?
Metamizole, the active ingredient in Novalgin, is a pyrazolone analgesic presented as an oral formulation for oral use. It provides relief from acute pain, fever, postoperative discomfort and visceral colic, primarily in adult patients. The drug works by inhibiting cyclooxygenase enzymes, reducing prostaglandin synthesis, and modulating central pain pathways, which contributes to its antipyretic and analgesic effects.
GNH USA supplies Novalgin as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
