Ph. Eur. 5.5 (Bromhexine Hydrochloride). A white or almost white crystalline powder. It exhibits polymorphism. Very slightly soluble in water; slightly soluble in alcohol and in dichloromethane. Protect from light.

Adverse Effects

Gastrointestinal adverse effects may occur occasionally with bromhexine and a transient rise in serum aminotransferase values has been reported. Other reported adverse effects include headache, dizziness, sweating, and skin rashes. Inhalation of bromhexine has occasionally produced cough or bronchospasm in susceptible subjects.


Since mucolytics may disrupt the gastric mucosal barrier bromhexine should be used with care in patients with a history of peptic ulcer disease. Care is also advisable in asthmatic patients. Clearance of bromhexine or its metabolites may be reduced in patients with severe hepatic or renal impairment.


Bromhexine hydrochloride is rapidly absorbed from the gastrointestinal tract and undergoes extensive first-pass metabolism in the liver: its oral bioavailability is stated to be only about 20%. It is widely distributed to body tissues. About 85 to 90% of a dose is excreted in the urine mainly as metabolites. Ambroxol (Go to Ambroxol Hydrochloride) is a metabolite of bromhexine. Bromhexine is highly bound to plasma proteins. It has a terminal elimination half-life of up to about 12 hours. Bromhexine crosses the blood-brain barrier and small amounts cross the placenta.

Bromhexine hydrochloride given by mouth to healthy subjects produced peak plasma concentrations after about 1 hour.1 Only small amounts were excreted unchanged in the urine with a half-life of about 6.5 hours.

Uses and Administration

Bromhexine is a mucolytic used in the treatment of respiratory disorders associated with productive cough (Go to Cough). Bromhexine is usually given by mouth in a dose of 8 to 16 mg of the hydrochloride three times daily. It has also been given by deep intramuscular or slow intravenous injection or inhaled as an aerosol solution.

Bromhexine has also been used orally and topically in the treatment of dry eye associated with abnormal mucus production (see Go to Dry eye.).

Dry eye.

Bromhexine has been used orally in the treatment of dry eye (Go to Dry eye) in Sjögren's syndrome but results have been conflicting,1-3 and it appears to have no effect on tear secretion in healthy subjects.4 It has also been tried topically.

Respiratory-tract infection.

Use with an antibacterial.

Bromhexine has been shown to enhance the penetration of erythromycin into bronchial secretions.1 Although bromhexine is used as an adjuvant in the treatment of respiratory infections, few controlled studies appear to have been conducted to determine if any additional benefit is obtained. However, some studies have found improved responses with cefalexin2 and amoxicillin.3
