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.

Current knowledge about the role of serotonin (5-HT) in central cardiovascular regulation is reviewed. Results from experiments with the 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) suggest that activation of somatodendritic 5-HT1A receptors in the medulla oblongata decreases the firing of
