Thera: erectile dysfunction agent, vaseodilator
Pharm: Phosphodiesterase-5 inhibitor
Indications: Ed, pulmonary arterial hypertension
MOA; inhibiting PDE-5 increases levels of cGMP which produces smooth muscle relaxation and increases blood flow to the corpus cavernosum,
Adverse: headache, dizziness, facial flushing, nasal congestion, hypotension

Implications: Viagra: seek medical attention 4 hours or more, does not prevent HIV/STD; Revatio: vital signs, cardiac function, exercise tolerance prior to and during therapy


Benign Prostatic Hypertrophy

Smooth muscle tissue surrounding urethra is regulated by alpha 1 adrenergic receptors
Glandular tissue regulated primarily by testosterone. Enzyme 5-alpha reductase converts testosterone to DHT, its active metabolites
DHT causes proliferation of prostate tissue - if we stop it we can reduce prostate size


BHP Drug Classes

5-alpha reductase inhibitors
-finasterides (Proscar), dutasteride (avodart)
Make take 3-6 months to read peak, monitors for sexual dysfunction, do not handle crushed or broken tablets if pregnant

Alpha 1 adrenergic blockers - cause vasodilation
-tamsulosin (Flomax), terazosin (Hytrin)
Monitor for postural hypotension (first does effect), sleep difficulties
