General Description

White or creamy white powder. pH (1% aqueous solution) between 4.9 and 5.1.

General Description

The acid succinate salt (bisuccinate)of doxylamine, 2-[ -[2-(dimethylamino)ethoxy]- -methylbenzyl]pyridine bisuccinate (Decapryn Succinate), isa white to creamy-white powder with a characteristic odor.It is soluble in water (1:1), alcohol (1:2), and chloroform(1:2). A 1% solution has a pH of about 5.Doxylamine succinate is comparable in potency todiphenhydramine. It is indicated for the relief of seasonalrhinitis symptoms, but is also used as a nighttime sedative.Concurrent use of alcohol and other CNS depressantsshould be avoided.

Air & Water Reactions

Water soluble.

Biochem/physiol Actions

H1 histamine receptor antagonist; hypnotic.Doxylamine suppresses histamine at the H1 receptor. It is associated with the short term management of insomnia and temporary relief of common cold symptoms. On the other hand, doxylamine intoxication is linked with rhabdomyolysis and secondary acute renal failure.Studies in mice show that doxylamine induces liver microsomal cytochrome P450 and other enzymes involved in thyroxine (T4) metabolism. In combination with pyridoxine hydrochloride, this drug is used to treat morning sickness.
