| | Doxylamine succinate Usage And Synthesis |
| Chemical Properties | white to light cream powder | | Uses | H1 Histamine receptor antagonist. Antihistaminic; sedative; hypnotic. | | Uses | antihistaminic, hypnotic | | Uses | Doxylamine succinate salt has been used as a therapeutic drug to check developmental toxicity. | | Definition | ChEBI: Doxylamine succinate is an organic molecular entity. | | Brand name | Decapryn (Sanofi Aventis); Unisom (Pfizer). | | 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. | | General Description | White or creamy white powder. pH (1% aqueous solution) between 4.9 and 5.1. | | Air & Water Reactions | Water soluble. | | Health Hazard | SYMPTOMS: Symptoms of exposure to Doxylamine succinate may include drowsiness, excitability, nervousness, dizziness and sleeplessness. | | Fire Hazard | Flash point data for Doxylamine succinate are not available. Doxylamine succinate is probably combustible. | | 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. |
