🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary mechanisms. Dicyclomine is an anticholinergic and antispasmodic agent that blocks muscarinic acetylcholine receptors in the gastrointestinal tract, reducing smooth muscle contractions and spasms. Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that reversibly inhibits cyclooxygenase enzymes (COX-1 and COX-2), decreasing the synthesis of prostaglandins, which are mediators of pain, inflammation, and fever. Together, they provide relief from both spasmodic and inflammatory components of abdominal pain.
