23
Q

What drug class are “FENAC” drugs in?

A

NSAIDs

24
Q

Pharmacologic Classification of NSAIDs.

A

Cyclo-oxygenase = COX inhibitor

Inhibition of COX enzymes and the related inhibition of Prostaglandin synthesis.

This is associated with inflammation and pain synthesis.

25
Q

Are NSAIDs or steroids more potent anti-inflammatory drugs?

A

Steroids are more potent

26
Q

Therapeutic Classification of NSAIDs.

A

Analgesic - relieve pain

Antipyretic - Fever reducing

Anti-inflammatory

27
Q

How does aspirin affect platelet function?

A

A single dose of Aspirin irreversibly inhibits platelet function for the 8 to 10 day life of the platelet.

28
Q

Two common side effects of aspirin.

A

GI bleeding and Tinnitus (ringing in the ears)

29
Q

Why is aspirin not recommended for children?

A

Reye’s Syndrome (ASA-specific)

A rare life-threatening condition in children, especially if aspirin is administered subsequent to a viral infection.

Results in liver failure, cerebral edema, encephalitis.

30
Q

DDI for NSAIDs (including aspirin)

A

NSAIDs [including aspirin] increase the INR in patients on warfarin, and increase the risk of bleeding.

31
Q

Yosprala® is an aspirin-omeprazole combo. What benefit does it have?

A

Used to protect against the GI effects of aspirin.

32
Q

Durlaza® vs OTC aspirin?

A

Aspirin 81 mg enteric - BID = 162 mg/day

Durlaza® 24-hour ER - 162.5 mg - Patients only have to take one day instead of two 81 mg aspirin

33
Q

How are non-selective COX inhibitors different from other NSAIDs? These NSAIDs end in what suffices?

A

Inhibit both COX 1 and 2 enzymes

  • PROFEN
  • FENAC
34
Q

Name 3 non-selective COX NSAIDs that do not end in -PROFEN or -FENAC.

A
  1. Aspirin
  2. Naproxen
  3. Indomethacin
35
Q

Naproxen advantages over Ibuprofen.

A

Longer duration of action than ibuprofen.

Twice a day is adequate enough for pain.

Lowest risk of cardiovascular side effects. Typically used for inflammation of the joints (i.e. arthritis)

36
Q

How are partially selective COX inhibitors different from other NSAIDs? Name two drugs in this group.

A

More selective than non-selective NSAIDs.

Less selective than COXIBs

Less likely to inhibit platelet aggregation or to cause GI bleeding

  1. Etodolac
  2. Meloxicam
37
Q

ADRs of NSAIDs

A
  1. Coagulation Disorders - increased risk of bleeding
  2. Pregnancy - increased risk of miscarriage. Should be discontinued (6 - 8 weeks prior to delivery)

A

Aspirin + Acetaminophen + Caffeine

COX-2 : produces inflammation and pain

42
Q

How COXIBs differ from other NSAIDs?

A
  1. Most selective
