Plasma protein binding: 39-49%. Metabolism: Undergoes N-dealkylation to form monodesmethylbrompheniramine and didesmethylbrompheniramine, and is metabolised to propionic acid derivative. Excretion: Via urine (approx 40%, as unchanged drug and metabolites) and faeces (approx 2%). Elimination half-life: Approx 25 hr. |
