- Cautions and Interactions:
- when discontinuing beta blockers, it is necessary to taper dose;
- aspirin (by inhibiting prostacycline) will decrease the effectivness of class II agents;
- beta-Adrenergic-receptor antagonists reduce the renal plasma flow & glomerular filtration rate & should
therefore be avoided in pts with renal impairment;
