Indoramin is an alpha-1 selective antagonist of adrenergic receptor, sold under trade names Baratol and Doralese, and now available as a generic. It has no reflex tachycardia and direct myocardial depression action and is used to treat benign prostate hyperplasia (as 20 mg tablets) or reduce blood pressure (as 25 mg strength tablets). It was also investigated as a treatment of a migraine and congestive heart failure.

Benign prostatic hyperplasia 28 Sources: http://www.mhra.gov.uk/home/groups/par/documents/websiteresources/con509423.pdf	Primary	Approved 8429	DORALESE Approved Use Indoramin 20 mg Tablets are used for a condition called ‘benign prostatic hyperplasia’ or BPH. The prostate is a gland found underneath the bladder in men. It surrounds the tube (called the urethra) which carries urine from the bladder to the outside of the body.

Sample Use Guides

In Vivo Use Guide

The recommended dose is one tablet (20 mg) twice a day. The tablet should be swallowed with water. Some elderly patients may need just one tablet at night. The patient’s doctor may increase their dose to a maximum total daily dose of 100 mg. The patient must not take more than their doctor has recommended.

Route of Administration: Oral

In Vitro Use Guide

Binding of indoramin to alpha1 receptors was studied using rat cerebral cortex membranes with [3H]prazosin to label alpha1 adrenoreceptors. Indoramin displaces prozasin with IC50 pKi of 7.61.
