Nac (Acetylcysteine)

Acetylcysteine, the active ingredient in Nac, is a mucolytic presented as an oral formulation for oral use. It reduces the viscosity of respiratory secretions and is employed in the management of chronic bronchitis, COPD and other conditions characterized by thick mucus.

GNH USA supplies Nac as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. All batches meet EU pharmacopeial standards and are shipped under controlled conditions. The company adheres to stringent quality assurance protocols and provides regulatory documentation to support import and distribution.

Acetylcysteine is used as a mucolytic agent to facilitate clearance of thick respiratory secretions in several chronic lung diseases.

- Chronic bronchitis: enhances mucus clearance, helping to alleviate cough and improve breathing. - Chronic obstructive pulmonary disease (COPD): reduces sputum viscosity, supporting airway patency during exacerbations. - Cystic fibrosis: thins airway mucus, aiding expectoration and reducing risk of infection.

Acetylcysteine is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Vomiting: occasional emesis after oral intake. - Diarrhea: loose stools in some patients. - Abdominal pain: cramping or discomfort. - Rash: transient skin erythema. - Metallic taste: brief after swallowing.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - Stevens‑Johnson syndrome: rare but serious skin eruption. - Bronchospasm: paradoxical airway constriction, especially in asthmatic patients. - Hepatic dysfunction: elevated liver enzymes in isolated cases. - Hemolysis: rare occurrence in patients with G6PD deficiency.

When using Acetylcysteine, consider the following precautions. - Renal function assessment: adjust use in severe renal impairment. - Monitor for bronchospasm: especially in patients with reactive airway disease. - Hypersensitivity avoidance: discontinue if allergic reactions develop. - Pregnancy caution: safety data are limited; use only if benefit outweighs risk. - Concomitant medication review: evaluate potential interactions. - Store at ambient temperature: keep in the original pack, protect from moisture.

Acetylcysteine may interact with other medicines; awareness of the level of interaction helps manage risk.

Major Interactions (Avoid): - Nitroprusside: may potentiate hypotensive effect. - Activated charcoal: can reduce oral absorption of acetylcysteine. - Carbapenem antibiotics (e.g., imipenem): may be inactivated when co‑administered.

Moderate Interactions (Monitor Closely): - Bronchodilators: may increase cough reflex. - Warfarin: possible alteration of INR, requiring monitoring. - Methotrexate: potential increase in toxicity; observe clinical parameters.
