Dapiprazole Hydrochloride is an alpha-1-adrenergic antagonist that acts by blocking alpha-adrenergic receptors in the smooth muscle of blood vessels (arteries, arterioles and veins), gastrointestinal tract, and radial smooth muscle of the iris. This prevents smooth muscle contraction and results in vasodilatation. Administered in the eye, dapiprazole hydrochloride produces miosis. In the heart, it may antagonize alpha-1 adrenoreceptors in myocytes causing a mild negative inotropic effect.

4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Adrenergic alpha-Antagonists

Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. (See all compounds classified as Adrenergic alpha-Antagonists.)


Antipsychotic Agents

Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus. (See all compounds classified as Antipsychotic Agents.)
