Pharmacotherapeutic group: Mycolytics, ATC code: R05CB01

N-acetyl-L-cysteine (NAC), the active ingredient in Acetylcysteine Alveda 200 mg Powder for Oral Solution exerts an intense mucolytic-fluidizing action on mucous and mucopurulent secretions by depolymerizing the mucoproteic complexes and the nucleic acids which confer viscosity to the vitreous and purulent component of the sputum and other secretions.

Furthermore, Acetylcysteine Alveda exerts a direct antioxidant action, having a free thiol (- SH) nucleophilic group that is able to interact directly with electrophilic groups of oxidant radicals. Of particular interest is the recent finding that Acetylcysteine Alveda protects α1-antitrypsin enzyme inhibiting elastase from inactivation by hypochlorous acid (HOCl), a powerful oxidant agent produced by the myeloperoxidase enzyme of activated phagocytes. Due to its molecular structure, Acetylcysteine Alveda can readily cross cell membranes. Inside the cell, NAC is deacetylated to L-cysteine, an amino acid essential for glutathione synthesis (GSH).

GSH is a highly reactive tripeptide found ubiquitously in the various tissues of animals and is essential for the maintenance of functional capacity as well as cellular morphological integrity. It is the most important protective intracellular mechanism against oxidant radicals, both exogenous and endogenous, as well as toward numerous cytotoxic substances.

These features make Acetylcysteine Alveda 200 mg Powder for Oral Solution particularly suitable for the treatment of acute and chronic affections of the respiratory system, characterised by thick, viscous mucous and mucopurulent secretions.

There is no evidence on the efficacy and safety of mucolytic s including Acetylcysteine Alveda in acute bronchitis.

Pharmacokinetic properties

The information provided in Pharmacokinetic properties of Acetylcysteine Alveda is based on data of another medicine with exactly the same composition as the Acetylcysteine Alveda of the medicine (Acetylcysteine).

Absorption

Following oral administration, Acetylcysteine Alveda is rapidly and almost completely absorbed and metabolised in the liver to cysteine (the pharmacologically active metabolite), diAcetylcysteine Alveda, cysteine and further mixed disulphides.

Distribution

Due to the high first-pass effect, the bioavailability of orally administered Acetylcysteine Alveda is very low (approximately 10%). In humans, maximum plasma concentrations are achieved after 1-3 hours with the maximum plasma concentration of the metabolite cysteine in the range of approximately 2µmol/l. The protein binding of Acetylcysteine Alveda was determined to be about 50%.

Biotransformation

Acetylcysteine Alveda and its metabolites occur in three different forms in the organism: partially in free form, partially bound to proteins via labile disulphide bonds and partially as incorporated amino acid. Acetylcysteine Alveda is excreted almost exclusively in the form of inactive metabolites (inorganic sulphates, diAcetylcysteine Alveda) via the kidneys. The plasma half-life of Acetylcysteine Alveda is approximately 1 hour and is mainly determined by the rapid hepatic biotransformation. Impaired hepatic function therefore leads to prolonged plasma half-lives of up to 8 hours.

Elimination

Pharmacokinetic studies with intravenous administration of Acetylcysteine Alveda revealed a distribution volume of 0.47 1/kg (in total) or 0.59 I/kg (reduced Acetylcysteine Alveda); the plasma clearance was determined to be 0.11 l/h/kg (in total) and 0.84 l/h/kg (reduced Acetylcysteine Alveda), respectively. The elimination half-life after intravenous administration is 30-40 minutes while excretion follows three-phase kinetics (alpha, beta and terminal gamma phase).

Acetylcysteine Alveda crosses the placenta and is detected in cord blood. No information is available regarding excretion in breast milk.

No knowledge is available concerning the behaviour of Acetylcysteine Alveda at the blood- brain barrier in humans

Acute toxicity studies in rats and mice, by oral, intraperitoneal and intravenous administration showed Acetylcysteine Alveda to be of low toxicity. LD50 values greater than 7 g / kg in mice and 6 g / kg in rats have been reported. Chronic toxicity studies with Acetylcysteine Alveda in rats at doses up to 2000 mg/ kg/ day and dogs at doses up to 300 mg/ kg / day for periods up to 52 weeks demonstrate that Acetylcysteine Alveda is well tolerated, even at higher doses. In reproductive toxicity studies in rats and rabbits, the oral administration of doses up to 2000 mg / kg / day did not show changes in reproductive capacity, teratogenic effects or peri/postnatal toxicity.
