NSAID available orally, IM, IV, nasally, and ophthalmically

A

Ketoralac

39
Q

NSAID used mostly for anesthesia and has limited duration (<5 days) due to nephrotoxicity

A

Ketoralac

40

A

Pre-existing cardiac or renal disease

42
Q

Two main actions of acetaminophen

A

Antipyretic and analgesic activity

43
Q

Inhibitor of lipoxygenase

A

Zileuton

44
Q

Major side effect of zileuton that limits its use

A

Liver toxicity

45
Q

Two leukotrienes (LTD4) receptor antagonists used in asthma

A

Zafirlukast and montelukast

46
Q

NSAID avoided in gout because low doses increases uric acid levels

A

Aspirin

47
Q

Side effects of colchicine

A

Diarrhea, liver toxicity, myelosuppression

48
Q

Recombinant uricase that enhances uric acid metabolism and indicated for gout refractory to conventional therapy

A

Pegloticase

49
Q

DMARDs are slow acting drugs for this indication

A

50
Q

1st line for rheumatoic arthritis for most patients

A

Low-dose methotrexate

51
Q

Dose-limiting toxicity of methotrexate

A

Myelosuppression

52
Q

A mixture of two agents with one agent active for rheumatic disease and the other for inflammatory bowel disease

A

Sulfasalazine

53
Q

Alternative to methotrexate as 1st line for rheumatoid arthritis through inhibition of dihydroorotate dehydrogenase, which leads to decreased pyrimidine synthesis

Q

These drugs strongly potentiate and prolong effect of neuromuscular blockers

A

Inhalation anesthetics (isoflurane), antibiotics (aminoglycosides, tetracyclines)

63
Q

Depolarizing blocker that causes muscle relaxation and paralysis and can cause postoperative muscle pain

A

Succinylcholine

64
Q

Two life-threatening side effects of succinylcholine

A

Hyperkalemia, malignant hyperthermia

65
Q

Drug for treating malignant hyperthermia associated with drug-drug interaction between halogenated anesthetics and depolarizing blocker

A

Dantrolene

66
Q

During Phase I depolarizing block this class of agents enhance muscle paralysis, but during Phase II block they may reverse muscle paralysis

A

Cholinesterase inhibitors

67
Q

Drug of choice for reversal of non-depolarizing neuromuscular blockade

A

Neostigmine

68
