Q

how do Ca2+ channel blockers lower blood pressure

A

block L-type Ca2+ channels of cardiac and smooth muscle –> decreased muscle contractility
(decreased risk of vasospasm, hence used in prinzmetal angina and raynaud’s)

Q

mechanism of fibrates

A
upregulate LPL (lipoprotein lipase) --> increased TG clearance
activate PPAR-alpha to induce HDL synthesis
28
Q

side effects of fibrates

A

myositis (esp w/ statins);
hepatotox;
cholest gallstones (esp w/ bile acid resins, “chol” “col”)

29
Q

mechanism of digoxin

A
direct inhibition of Na/K ATPase --> indirect inhib of Na/Ca exchanger --> increased intracellular Ca --> increased contractility;
stimulates vagus (how???) --> decreased HR
30
