General description

The adrenoreceptor α 1a gene (ADRA1A) is mapped to human chromosome 8p21.2. It codes for an α-adrenergic receptor.

Biochem/physiol Actions

α1-adrenoceptor antagonist; 5-HT1A serotonin receptor partial agonist; anti-hypertensive.
The adrenoreceptor α 1a gene (ADRA1A) participates in smooth muscle contraction. It is also required for vasoconstriction of blood vessels throughout the body such as the skin, gastrointestinal system, genitourinary system, kidney and brain. ADRA1A plays a major role in glycogenolysis and gluconeogenesis of adipose tissue in the liver. It also plays a crucial role in sympathetic nervous system.

Preparation Note

Urapidil hydrochloride is soluble in water at 25 mg/ml to yield a clear, colorless to very faint yellow solution.

The alpha-adrenoceptor antagonist urapidil influences central cardiovascular regulation, and this effect is unrelated to alpha-adrenoceptors. Since urapidil has appreciable affinity and selectivity for serotonin-1A (5HT1A) receptors, the activity of urapidil at these sites may be relevant for the centrally mediated
