Antrenex

Antrenex Uses, Dosage, Side Effects, Food Interaction and all others data.

Antrenex is an anticholinergic drug, a medication that reduces the effect of acetylcholine, a chemical released from nerves that stimulates muscles, by blocking the receptors for acetylcholine on smooth muscle (a type of muscle). It also has a direct relaxing effect on smooth muscle. Antrenex is used to treat or prevent spasm in the muscles of the gastrointestinal tract in the irritable bowel syndrome. In addition, Antrenex inhibits gastrointestinal propulsive motility and decreases gastric acid secretion and controls excessive pharyngeal, tracheal and bronchial secretions.

How Antrenex works

Action is achieved via a dual mechanism: (1) a specific anticholinergic effect (antimuscarinic) at the acetylcholine-receptor sites and (2) a direct effect upon smooth muscle (musculotropic).

Dosage

Children: ½ to 1 tablets 1-3 times daily

Side Effects

Dryness of mouth, difficulty in talking/swallowing; reduced bronchial secretions; blurring of vision, photophobia; bradycardia followed by tachycardia and arrhythmias; urinary retention, constipation, vomiting, nausea; confusion and giddiness.

Precaution

Pregnancy & Breastfeeding use

Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
