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.

One such study involved alkylation of 4-benzamidopyridine (2) with a bromoethyy compound (1) derived from tryptophol, to give a quaternary pyridinium salt (3); this intermediate was in turn hydrogenated with a Raney nickel catalyst to give indoramine.[6][7]

Product withdrawal

[edit]

On May 31, 2013, the French National Agency for the Safety of Medicines and Health Products (ANSM) concluded that the benefit/risk ratio of this product was unfavorable and withdrew Vidora's marketing authorization and recalled its batches from the market on June 3, 2013.[8]
