Ingredient-level reference

Erdosteine

Reference for: Erdosteine. Source presentation: CAPSULE. Source route: oral.

Mechanism of action

Erdosteine is a prodrug whose active thiol-containing metabolite disrupts disulfide bonds in bronchial mucoproteins, reducing mucus viscosity. The reference also describes experimental antioxidant activity.

Pharmacokinetics

Rapid oral absorption is followed by first-pass formation of active metabolite M1. In the cited 300 mg study, parent drug peaked at about 1.18 hours and M1 at 1.48 hours. Their elimination half-lives were approximately 1.46 and 1.62 hours respectively. Parent-drug protein binding averaged 64.5%. Urine contained M1 and sulfate products, while fecal elimination was negligible. These values concern the capsule study, not a fixed combination.

Ingredient-level summary of the cited reference product. Study formulation, route, strength and population govern interpretation; these data do not establish pharmacokinetics or bioequivalence for Walter's formulation or fixed combination.
