Adult Meltus for Dry Tickly Coughs and Catarrh contains dextromethorphan hydrobromide and pseudoephedrine hydrochloride to provide cough suppression and bronchodilation in cases of dry irritating coughs.
Pseudoephedrine is readily and completely absorbed from the gastrointestinal tract following oral administration with no presystemic metabolism, achieving peak plasma concentrations between one and three hours after oral dosing. It has a plasma half-life of 5 to 8 hours following oral dosing but its urinary elimination and hence its half-life is pH dependant such that elimination will be increased in subjects with acidic urine and decreased in subjects with alkaline urine. Dextromethorphan is well absorbed following oral administration but is subject to extensive presystemic metabolism in the liver. The main metabolite is dextrorphan. Dextromethorphan is extensively biotransformed in the liver with about 50% of the dose excreted in the urine over 24 hours. Less than 1 % of a dose being excreted in the faeces. About 8% of the dose is excreted as unchanged drug in the urine within 6 hours.
Preclinical Safety Data There are no preclinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
