Answer
mild sx: conservative rx (watchful waiting) - 50% improve spontaneously
--lifestyle changes
med:
--α-adrenergic antagonists (relaxes bladder neck & prostate) - tamsulosin, alfuzosin, silodosin (these don't affect BP)
--5-α reductase inhib (shrink prostate by blocking conversion of testosterone to DHT) - finasteride, dutasteride
--combination (α-blocker + 5-α inhib) → slows progression
--tadalafil (ED drug) - beneficial effects on sx's (works on bladder + prostate)
--antimuscarinics (add to α-blockers if storage sx's) - works on bladder (don't give if no storage sx/poor flow/high residual urine)
