  1. Monteleukast
  2. Zafirleukast
  3. Zieuton

What is their main SIDE EFFECT?

Study These Flashcards
A

ORAL

  • Hypotension!!

( Monteleukast also has behavioral changes)

18
Q

Indication for monteleukast?

Study These Flashcards
A

Allergic reaction

19
Q

Indication for zafirleukast & ZIEUTON

MOA? (review)

Study These Flashcards
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?

Study These Flashcards
A

Asthma

  • Montefleukast
  • Zafirleukast
  • Zileuton
21
Q

State the following for aspirin:

MOA
Route

Study These Flashcards
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)
Study These Flashcards
A
  1. ACS
  2. Stroke
  3. Arterial Thrombosis
  4. Bleeding
  5. Gastric irritation
23
Q

State the following for Clopidogrel:

MOA
Route

Study These Flashcards
A
  1. ADP receptor inhibitor

2. ORAL

24
Q

State the following for Clopidogrel:

Indications (3)
Adverse Effects (2)
Study These Flashcards
A
  1. ACS
  2. Stroke
  3. In STENT THROMBOSIS

BLEEDING
& TTP!!

Arterial thrombosis, stroke BLEEDING
33
What are the 2 phosphodiesterase inhibitors?
Dypyramidole, Cilostazol
34
Cilostazol: MOA Route
MOA: phosphodiesterase inhibitor Oral
35
Cilostazol: Indication Side effect
INTERMITTENT CLAUDICATION Adverse = HYPOTENSION! (phosphodiesterase inhibitor ; Oral)

38
What is the absolute contraindication of thrombolytic therapy (with streptokinase/urokinase) 3 Drug interactions?
1. Intracranial bleeding 2. Massive hemorrhage 3. PREGNANCY Drug interactions: Antiplatelet Drugs Heparin Dextrans (coronary vasodilation)
39
A elderly patient was accidently overdosed with streptokinase. Which of the following agent can be used to neutralize bleeding complications? ``` Protamine sulfate Vitamin K Epsilon aminocaproic acid Factor VIIa Factor VIII concentrate ```
EACA
40
Which of the following mechanisms represents the main effect of thrombolytic agents? Reduces the circulating levels of platelets Converts plasminogen to plasmin Interacts with antithrombin Interacts with heparin cofactor II Decreases the synthesis of fibrinogen in the liver
Converts plasminogen to plasmin
