1. impotence
2. exacerbation asthma 3. cardio - bradycardia, AV block, CHF 4. CNS - seizures, sedation, sleep alteration - use with caution in diabetics - combo CCB cause arrest/bradycardia |

non selective beta antagonists
|
1. propranolol
2. timolol 3. nadolol 4. pindolol 5. carvedilol - also inhibit alpha via arrestin pathway 6. labetaolol - also inhibit alpha via arrestin pathway - nonselective blockers decrease gluconeogenesis and glycogenolysis so be careful in diabetics |
