20
Q

Name an example of a phosphodiesterase-4 (PDE-4) Inhibitor

A

Roflumilast

via oral

21
Q

Inhibition of PDE-4 prevents breakdown of ____ resulting in ____ inflammatory cell activity, inhibition of ______ and _____ of smooth muscle.

A

Inhibition of PDE-4 prevents breakdown of cAMP resulting in reduced inflammatory cell activity, inhibition of fibrosis and relaxation of smooth muscle.

22
Q

What is Roflumilast indicated for?

A

Reduces episodes of exacerbation
Slows progress of fibrosis

23
Q

What are some adverse effect of Roflumilast?

A

Headache
Dizziness
Insomnia
Diarrhoea
Nausea
Decreased appetite
Weight loss

**caution in patients with hepatic impairment!

24
Q

Can a patient with liver disease be prescribed Roflumilast?

A

Yes but use with caution as Roflumilast relies on hepatic clearance

25
Why is Azithromycin used in the treatment of COPD?
It works by preventing bacteria from growing by interfering with their protein synthesis Azithromycin is also an antifibrotic and smooth muscle relaxant which reduces the risk of exacerbations or exacerbations due to bacterial infection
26
What group of antibiotic does Azithromycin belong to?
Macrolide
27
What are the adverse effects of Azithromycin?
Diarrhoea Nausea and vomiting Cardiac arrhythmia
28
Azithromycin is contraindicated in patients with a history of _____ or _____

cysteine derivatives - acetylcysteine, carbocisteine thiol derivatives - erdostein (effervescent tablets and oral granules)
34
what is the MOA of mucolytics
- free sulfhydryl group opens disulphide bonds in mucoproteins - lowers mucous viscosity
35
what are the adverse effects of mucolytics
- bronchospasm - anaphylactoid reactions - rash/HTN/dyspnoea/wheezing - GI disturbance
36
what are the cautions of COPD
elderly or weakened patients with severe resp insufficiency asthma patients
