Gastrointestinal Antispasmodics

Gastrointestinal antispasmodics are medications used to relieve smooth muscle spasms, reduce abdominal cramping, and improve comfort in gastrointestinal disorders. These agents include anticholinergics, calcium channel modulators, direct smooth muscle relaxants, and selective agents targeting visceral hypersensitivity. They work by inhibiting excessive smooth muscle contraction, reducing neural excitability, or modulating pain pathways. Antispasmodics are widely used in irritable bowel syndrome, functional abdominal pain, gastrointestinal colic, and spasm-related dysmotility. Their benefits include reducing pain, gas, and bowel movement irregularities. However, anticholinergic drugs may cause dry mouth, blurred vision, constipation, or urinary retention, requiring dose adjustments based on tolerability. Antispasmodics play an important role in symptomatic relief for both acute and chronic gastrointestinal syndromes.
