  Promethazine (PIM 439)
Promethazine is metabolized principally to promethazine sulphoxide and to a lesser degree desmethylpromethazine.
Promethazine rapidly crosses the blood brain barrier and it is thought that the sedative effects of antihistamines are due to blockade of H1 receptors in the brain (Quach et al., 1979).
Promethazine is unstable in aqueous and organic solvents (Meaking et al., 1978) and, due to its large volume of distribution, is present in very low concentrations in body fluids.
