Indoramin (trade names Baratol and Doralese) is a piperidine antiadrenergic agent.

It is an alpha-1 selective adrenoceptor antagonist[1] with direct myocardial depression action; therefore, it results in no reflex tachycardia. It is also used in benign prostatic hyperplasia (BPH).[2]

It is commonly synthesized from tryptophol.[3]

Dosage[edit]

Indoramin is commonly prescribed as 20 mg tablets when used in BPH.[4]

Side Effects[edit]

Drowsiness, dizziness, dry mouth, nasal congestion, headache, fatigue, weight gain, hypotension, postural hypotension, depression, problems with ejaculation, diarrhoea, nausea, increased need to pass urine, and palpitations.[5]

Synthesis[edit]

Tryptamine and serotonin are naturally occurring indole ethylamino compounds with pronounced pharmacological activities. They have served as the inspiration for synthesis of numerous analogues.

α1-Adrenergic blocking agent with antihypertensive and bronchodilating activity. Prepn:[6][7]

One such study involved alkylation of 4-benzamidopyridine (2) with 3-(2-Bromoethyl)-1H-indole (1) to give quaternary salt (3); this intermediate was in turn hydrogenated with a Raney nickel catalyst to give indoramine (4).
