Mucosolvan Pro Dospělé (Ambroxol Hydrochloride)

Ambroxol Hydrochloride is used as an expectorant in respiratory conditions where thick mucus impairs clearance.

• Acute bronchitis with productive cough: reduces mucus viscosity and promotes expectoration.
• Chronic bronchitis: aids in clearing persistent sputum and improves breathing comfort.
• Chronic obstructive pulmonary disease (COPD): facilitates mucus clearance to lessen cough frequency.

• Ambroxol Hydrochloride acts on the respiratory epithelium by stimulating serous gland secretion and enhancing ciliary activity. The increased watery secretion dilutes mucus, while the heightened ciliary beat frequency promotes transport of the loosened secretions toward the pharynx, resulting in easier expectoration. The combined effect lowers mucus viscosity and improves clearance of bronchial secretions.

Ambroxol Hydrochloride may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Taste disturbance: a temporary bitter or metallic taste in the mouth.
• Nausea: mild stomach upset after oral administration.
• Abdominal discomfort: mild cramps or discomfort in the abdomen.
• Diarrhoea: loose stools occurring shortly after dosing.
• Headache: mild to moderate headache.
• Skin rash: mild erythema or itching.

Serious or Rare Side Effects

• Allergic reactions: urticaria, swelling, or anaphylaxis.
• Angioedema: rapid swelling of face, lips, or tongue.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Eosinophilia: elevated eosinophil count in blood.
• Hepatic enzyme elevation: increased ALT/AST levels.
• Neutropenia: reduced neutrophil count leading to infection risk.

When prescribing Ambroxol Hydrochloride, several safety considerations should be observed.

• Assess renal function: adjust use in patients with severe renal impairment.
• Monitor for allergic reactions: discontinue if rash, urticaria, or anaphylaxis occurs.
• Caution in asthma: ensure cough is productive before use to avoid airway obstruction.
• Avoid concomitant antitussives: do not combine with cough suppressants that may retain mucus.
• Pregnancy and lactation: use only if benefit outweighs potential risk, as safety data are limited.
• Store at ambient temperature below 25 °C: keep in the original packaging, protect from moisture and direct sunlight.

Ambroxol Hydrochloride can interact with other medicines, affecting efficacy or safety.

Major Interactions (Avoid)

• Antitussive agents (e.g., codeine, dextromethorphan): may suppress cough and hinder mucus clearance.
• Strong CYP2D6 inhibitors (e.g., fluoxetine, paroxetine): may increase ambroxol plasma levels, raising risk of side effects.

Moderate Interactions (Monitor Closely)

• Bronchodilators (e.g., salbutamol): may have additive respiratory effects; monitor response.
• Antibiotics metabolised by the liver (e.g., erythromycin): ambroxol may alter their pharmacokinetics.
• Anticoagulants (e.g., warfarin): occasional reports of altered INR; check coagulation parameters.
