The blood pressure decrease associated with alpha blockers tends to be more orthostatic in nature, that is, BP will drop suddenly upon standing. For this reason, alpha blockers are considered a relatively poor means of controlling BP, but they are very useful for men with BPH (benign enlarged prostates) who have difficulties urinating. The prostate gland is loaded with alpha 1 adrenergic receptors, and blockading those receptors will tend to relax the prostate muscles and ease the constriction on urine flow.Todd
