  1. Monteleukast
  2. Zafirleukast
  3. Zieuton

What is their main SIDE EFFECT?

A

ORAL

  • Hypotension!!

( Monteleukast also has behavioral changes)

18
Q

Indication for monteleukast?

A

Allergic reaction

19
Q

Indication for zafirleukast & ZIEUTON

MOA? (review)

A

asthma

  • leukotriene receptor inhibitor = zafirleukast
  • lipooxygenase inhibitor zileuton
20
Q

What 3 drugs can be used for the treatment of asthma?

Which is specifically for seasonal allergies?

A

Asthma

  • Montefleukast
  • Zafirleukast

21
Q

State the following for aspirin:

MOA
Route

A

COX inhibitor; ORAL

(Aspirin acts as an irreversible inhibitor of COX1 by acetylating Ser530
in the active site thereby preventing access to arachidonic acid substrate)

Aspirin also acetylates COX-2, but is a less potent inhibitor,
as the COX2 active site is larger and can still partially bind arachidonic acid

22
Q

State the following for aspirin:

Indications (3)
Adverse Effects (2)
A
  1. ACS
  2. Stroke
  3. Arterial Thrombosis
  4. Bleeding
  5. Gastric irritation
23
Q

State the following for Clopidogrel:

MOA
Route

A
  1. ADP receptor inhibitor

2. ORAL

  2. Stroke
  3. In STENT THROMBOSIS

BLEEDING
& TTP!!

25
Q

Which drug has an adverse effect of Thrombotic Thrombocytopenic Purpura?

A

CLOPIDROGEL

decreased ADAMTS13 leading to large wf multimers occluding small vessels

26
Q

What 3 drugs are ADP inhibitors?

A
  1. Clopidrogel
  2. Prasugrel
