The risk of first dose phenomenon may be reduced or eliminated by gradual-dose titration, since the adverse effects of Prazosin are dose-related. [7] This is also the case for Tamsulosin and it may be assumed that the others alpha-1 blockers work in a similar manner, since Tamsulosin is an alpha-1-a blocker and Prazosin is an alpha-1 blocker ...
Doxazosin: Cardura Cardura XL Competitive blocking of α 1 receptor. [10] Lowers blood pressure. [2] Hypertension; Benign prostatic hyperplasia [5] First dose effect; Orthostatic hypotension; Nasal congestion; Dizziness; Lack of energy; Headache; Drowsiness [2] [10] Terazosin: Hytrin Competitive blocking of α 1 receptor.

Other drugs of the same family, doxazosin (Cardura) and terazosin (Hytrin), can also cause this phenomenon, though less frequently. The cause is not clear. It occurs more commonly in patients who are salt and fluid volume depleted (as happens due to the use of diuretics ), or were using beta blockers . [ 4 ]
Given its long half-life, doxazosin lasts much longer than prazosin. While prazosin is dosed up to 4 times daily, doxazosin is generally dosed only once daily (at night). Both are alpha-1 antagonists. Other sympatholytic drugs include clonidine and guanfacine, which are alpha-2 agonists; they are not in the same exact class as doxazosin and ...
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
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, feeling tired, swelling, nausea, and low blood pressure with ...
Alpha-blockers, including prazosin, terazosin, doxazosin, or tamsulosin, do not appear to affect all-cause mortality in heart failure rehospitalization in those also receiving β-blockers. [23] Tamsulosin can also cause retrograde ejaculation, which occurs when semen is redirected to the urinary bladder instead of being ejaculated normally.
ALLHAT showed that doxazosin, an alpha-adrenergic receptor blocker, had a higher incidence of heart failure events, and the doxazosin arm of the study was stopped.) A subsequent smaller study (ANBP2) did not show the slight advantages in thiazide diuretic outcomes observed in the ALLHAT study, and actually showed slightly better outcomes for ...
