Indomethacin Sodium

**Semantic type:** Pharmacologic Substance

**Definition:** The sodium salt of indomethacin, a methylated indole derivative with anti-inflammatory, analgesic-antipyretic and tocolytic effects. Indomethacin is a non-selective, reversible, and competitive inhibitor of cyclooxygenases 1 and 2, thereby blocking the conversion of arachidonic acid into prostaglandin precursors. Consequently, prostaglandin synthesis is decreased, and prostaglandin-mediated activities are prevented, including pain, inflammation, fever and uterine contraction.

**Synonyms:** - INDOMETHACIN SODIUM - Indocin I.V.
