Antrenex is indicated for:
Pharmacology
Oxyphenonium belongs to a class of medicines called anticholinergics (antimuscarinics). It works by blocking the action of acetylcholine, a chemical released by nerves that normally stimulates muscle activity, at receptors found on smooth muscle. Alongside this, it also relaxes smooth muscle directly. Because of these actions, Oxyphenonium is prescribed to treat and prevent muscle spasms in the gastrointestinal tract associated with irritable bowel syndrome. It also slows down the natural propulsive movements of the gut, reduces the secretion of stomach acid, and helps control excessive secretions in the throat, windpipe, and bronchial airways.

Additional contraindications include myasthenia gravis and known hypersensitivity to the drug.
