What is ED?
- Inability to achieve or maintain an erection
- Affects 65% of men between 40-70 years of age
-
Describe the pathophysiology of ED
arousal -> Ach released from pelvic nerve-> NO released from cavernosal nerves-> smooth muscle relaxation-> areterial inflow/decreased venous outflow-> penile rigidity
Endothelial damage--> decreaseNO production
-
What are risk factors for ED?
- Medications
- CV disease
- Diabetes

- Medications: phosphodiesterase type 5 (PDE5) inhibitors, Yohimbine
- Surgical: Vasoactive injection therapy, vaccum pump devices, penile prosthesis
-
How do PDE5 inhibitors work?
Inhibit cGMP --> build up of cGMP--> smooth muscle relaxation--> increased inflow of blood
SE: headache, flushing, dyspepsia, rhinitis, impaired color discrimination, dizziness, hypotension, CV effects, sudden hearing loss
