}}Terazosin, sold under the brand name Hytrin among others, is a medication used to treat symptoms of an enlarged prostate and high blood pressure.[1] For high blood pressure, it is a less preferred option.[1] It is taken by mouth.[1]

Common side effects include dizziness, headache, tiredness, swelling, nausea, and low blood pressure with standing.[1] Severe side effects may include priapism and low blood pressure.[1] Prostate cancer should be ruled out before starting treatment.[1] It is an alpha-1 blocker and works by relaxing blood vessels and the opening of the bladder.[1]

Terazosin was patented in 1975 and came into medical use in 1985.[2] It is avaliable as a generic medication.[9] A month supply in the United Kingdom costs the NHS less than 2 £ as of 2019.[3] In the United States the wholesale cost of this amount is about 4.50 USD.[4]

Formulations

It is available in 1 mg, 2 mg, 5 mg or 10 mg doses.[5]

Synthesis

Reaction of piperazine with 2-furoyl chloride followed by catalytic hydrogenation of the furan ring leads to 2. This, when heated in the presence of 2-chloro-6,7-dimethoxyquinazolin-4-amine (1) undergoes direct alkylation to terazosin (3).
