CLINICAL PHARMACOLOGY

Deconsal® CT (phenylephrine hcl and pyrilamine maleate tannate chewable tablets) Tannate Chewable Tablets combines the sympathomimetic decongestant effect of phenylephrine with the antihistaminic effect of pyrilamine.

Phenylephrine

Phenylephrine is a decongestant which is a potent postsynaptic a-receptor agonist with little effect on p receptors of the heart. A direct action at the receptors accounts for the greater part of its effects, only a small part being due to its ability to release norepinephrine. Phenylephrine has no effect on p-adrenergic receptors of the bronchi or peripheral blood vessels. Phenylephrine has a mild stimulant effect.

Pyrilamine

Pyrilamine is an antihistamine, Hi receptor blocking agent belonging to the ethylenediamine class of antihistamines. Hi-blocking drugs inhibit the actions of histamine on smooth muscle, capillary permeability, and can both stimulate and depress the central nervous system. Pyrilamine also possesses anticholinergic and sedative properties.
