(1. Bisoprolol with carvedilol, 2. Furosemide with bumetanide, 3. Sacubitril with valsartan, 4.
Spironolactone with eplerenone) - Answer Sacubitril with valsartan: sacubitril is combined

What is the primary mechanism of action of bile acid binding resins in managing dyslipidemia?
(Increasing LDL receptor expression, Enhancing triglyceride synthesis, Inhibiting cholesterol
absorption, Sequestering bile acids in the intestine) - Answer Sequestering bile acids in the
intestine: Bile acid sequestrants (BASs) bind to bile acids in the intestine and inhibit their
absorption. Bile acids are derived from cholesterol and increased bile excretion significantly
lowers the cholesterol content of the body.
