Q

indication for nicotinic acid

A

hypertriglyceridemia
hypercholesterolemia
mixed dyslipidemia

17
Q

Biguanide-based; activates AMP-activated protein kinase (AMPK) which in turn suppresses hepatic gluconeogenesis & intestinal glucose absorption; increases insulin sensitivity

A

metformin moa

18
Q

indication for metformin

A

DM 2 and PCOS

19
Q

Stimulates pancreatic islet beta cell insulin release

Actions involve binding to an ATP-dependent K+ channel: blocked efflux leads to depolarization, Ca++ release and insulin vesicle effusion

A

moa for glipizide

20
Q

indication for glipizide

A

DM 2

21
Q

A thiazolidinedione (aka glitazone) insulin sensitizer selectively stimulates nuclear receptor PPAR which increases insulin sensitivity in liver, skeletal muscle and adipose tissue

A

MOA of pioglitazone

22
Q

indication of pioglitazone

A

dm 2

23
Q

sitagliptin moa

A

Inhibits dipeptidyl peptidase-4, slowing incretin breakdown, increasing insulin synthesis/release, decreasing glucagon levels

24
Q

indiaction for sitagliptin

A

dm2

25
Q

Slow release, micro-crystallized rDNA insulin analog for stable day-long blood sugar regulation to be used in post-prandial combination with fast acting insulin

A

moa for insulin glargine

26
Q

Irreversibly inhibits gastric parietal cell H+-K+-ATPase, thereby inhibiting gastric acid secretion

A

esomeprazole moa

27
Q

indication for esomeprazole

A

GERD
Gastric ulcer prophylaxis (nsaid associated)
hypersecretory disorders
h. pylori infection

28
Q

Selective antagonism of gastric parietal cell H2 receptors

A

cimetidine moa

29
Q

cimetidine indications

A

gerd
peptic ulcer
dyspepsia

30
Q

Synthetic T4 (tetra-iodothyronine)

A

levothyroxine

31
Q

indication for levothyroxine

A

hypothyroidism

32
Q

Binds to estrogen receptors, developing and maintaining female sex characteristics and reproductive systems

A

estrone moa

33
Q

estrone indication

A

Menopause, Breast Cancer, Prostate Cancer, Osteoporosis prevention

34
Q

Having a strong affinity for Ca2+, these drugs accumulate in bone where, upon ingestion by osteoclasts, they inhibit the HMG-CoA reductase pathway and leads to cell death, reducing bone resorption and turnover (bisphosphonate)

A

alendronate moa

35
Q

indication for alendronate

A

Osteoporosis

Paget’s Bo Dz

36
Q

Acts as a folic acid analogue, inhibits DHFR, thus preventing formation of FH4

Inhibits lymphocyte proliferation

A

methotrexate moa

37
Q

indication for methotrexate

A

RA
psoriasis
Choriocarcinoma
