PHARMACODYNAMICS
Dextromethorphan suppresses the cough reflex by a direct central action,
probably in the medulla or pons.
PHARMACOKINETICS:
Dextromethorphan HBr is absorbed after oral administration. After an oral
dose of 30 mg, 10, 25 and 10% of the dose is detectable in the blood at 1,
2.5, and 6 hours respectively after administration. It is metabolised by
N-Demethylation and O-Demethylation followed by Sulphate or Glucuronic Acid
conjugation; the major metabolite is (+)-3-hydroxy-N-methylmorphinan and the
other metabolites are (+)-3-hydroxymorphinan and possibly
(+)-3-methoxymorphinan and their respective conjugates. Up to 56% of a dose
is excreted in the urine, about 8 % being excreted unchanged in 6 hours, in
rats, Dextromethorphan is excreted in the bile and twice as much may be
detectable in the faeces as in the urine.
INDICATION
Symptomatic relief of unproductive cough caused by minor throat and
bronchial irritation occurring with colds or inhaled irritants.

Dextromethorphan has teratogenic potential.
There is no data on the secretion of Dextromethorphan into breast milk and
therefore use of this product during lactation should be avoided.
