Q

phentolamine

A

alpha 1 and 2 adrenoceptor antagonist

20
Q

niacin

A

treatment for hypercholesterolaemia mechanism unclear –> reduces secretion of VLDL from liver and therefore reduces plasma LDL and TG

21
Q

Digoxin

A

Cardiac glycoside - inhibits Na/K ATPase pump in cardiac myocytes –> increasing Ca store in SR and therefore increases contractility

21
Q

ezetimibe

A

treatment for hypercholesterolaemia specifically inhibits cholesterol absorption in the intestine by binding to a sterol transporter

22
Q

beta adrenoceptor antagonists

A

B1 and B2 - propranolol B1 - atenolol

23
Q

isosorbide dinitrate

A

long-acting nitrate used to treat angina reduces preload via venous dilation

24
Q

GTN

A

nitrate - used to treat angina reduces preload via venous dilation

26
Q

Verapamil

A

cardioselective Ca2+ channel blocker Acts preferentially on the AV and SA nodes slows conduction velocity and increases refractoriness

27
Q

Calcium channel blockers

A

verapamil diltiazem felodipine nifedipine

28
Q

edrophonium

A

AChE inhibitor used in DIAGNOSIS of myaesthenia gravis

29
Q

streptokinase

A

fibrinolytic drug activates plasminogen antigenic - single use only IV

30
Q

prazosin

A

alpha1 adrenoceptor antagonist used in hypertension

31
Q

aspirin

A

anti-platelet aggregation and activation irreversible COX inhibitor –> reduced thromboxane synthesis –> decreased platelet aggregation and vasoconstriction

32
Q

carvedilol

A

Beta 1 and alpha 1 blocker Vasodilation –> reduces afterload Decreases HR and contracility Inhibits renin release and subsequent effects Protects against R downregulation

33
Q

alteplase

A

fibrinolytic drug more active on fibrin bound plasminogen IV

34
Q

hydrochlorothiazide

A

diuretic used to treat high blood pressure

35
Q

isoprenaline

A

B1 and B2 adrenoceptor agonist

35
Q

warfarin

A

anti-coagulant inhibits reduction of vitamin K –> inhibiting gamma carboxylation of glutamate in factors II, VII, IX and X

37
Q

alpha 1 and 2 antagonists

A

alpha 1 and 2 = phentolamine alpha 1 = prazosin

38
Q

Furosemide

A

Diuretic for treatment of heart failure Acts on the loop of henle Reduces blood volume and therefore preload

39
Q

AChE inhibitors

A

edrophonium neostigmine pyridostigmine donepezil

41
Q

propranolol

A

B1 and B2 adrenoceptor antagonist

42
Q

dobutamine

A

beta1-adrenoceptor agonist Increase HR and contracility Used for acute heart failure Not used for chronic - as increases oxygen demand of heart muscle and increases the risk of arrythmias

43
Q
