Q

What is used to treat COPD?

A

Inhalers:
- Short acting anti-muscarinic antagonist = Ipratropium

  • Long acting anti-muscarinic = Aclidinium bromide, glycopyrronium bromide and umeclidimium
  • Mucolytic drugs = Carbociestine
  • Long term oxygen = given for severe COPD & hypoxaemia

Antibiotics = for infection, if phlegm becomes purulent than usual

  • Steroids (either inhaled like ICS or oral like Prednisolone)

Q

What is the initial treatment of COPD?

A

A SABA or a SAMA
Used for quick relief.

Whether they have asthmatic features or not.

18
Q

What needs to be done for patients starting LAMA?

A

Stop SAMA.

They can either have SAMA or LAMA

19
Q

What is the step up treatment without asthmatic features?

A
  • SABA or SAMA

If doesn’t work then add LABA and LAMA (own 3 inhalers in total)

SAMA - stopped
SABA - continued

Add ICS if:
- severe exacerbation within a year and needed to go hospital or TWO exacerbations needing Prednisolone/antibiotics.

So patient would now own 4 inhalers

20
Q

What is the step up treatment with asthmatic features?

A
  • SABA or SAMA

If doesn’t work then add LABA and ICS (own 3 inhalers in total - SABA, LABA n ICS)

SAMA - stopped
SABA - continued

Add LABA if:
- severe exacerbation within a year and needed to go hospital or TWO exacerbations needing Prednisolone/antibiotics.

So patient would now own 4 inhalers (SABA, LABA, ICS, LAMA)

21
Q

What is Trixeo Aerosphere used for and what does it contain?

A

Used in exacerbations of COPD, with asthmatic features.

Contains:
- Formoterol (LABA)
- Glycopyrronium (LAMA)
- Budesonide (ICS)

22
Q

What is CROUP?

A

A, usually, self-limiting infection of the upper airways that causes breathing difficulty and a BARKING cough.

Common in babies and young children. Worse at night.

23
Q

For mild croup, use single dose steroid (dexamethasone).
If severe, give single dose steroid.

25
Q

What should be given if single dose steroid doesn’t work?

A

Give nebulised adrenaline (reduces airway swelling)

And monitor child carefully to see if croup returns.

26
Q

What are Antihistamines for?

A

Nasal allergies and seasonal allergic rhinitis (inflammation of inside of nose caused by an allergen)

  • To treat urticaria (itchy rashes/hives)
  • rashes

  • Promethazine
29
Q

What are the non-sedating antihistamines?

A
  • Cetirizine
  • Acrivastine
  • Bilastine
  • Loratadine
  • Desloratadine
  • Fexofenadine
  • Mizolasatine
  • Rupatadine
30
Q

What are the cautions of anti-histamines?

A

For sedating anti-histamine, there is a caution in:
- prostatic hypertrophy (prostate enlargement)

  • Urinary retention
  • Epilepsy

AND AVOID IN LIVER DISEASE - risk of coma

31
Q

Which patients are more susceptible to side effects of antihistamines?

A

Children and Elderly

32
Q

33
Q

What is Cystic fibrosis?

  • Pancreas
  • Liver
  • Intestines
  • Productive organs
34
Q

What are the symptoms of Cystic Fibrosis?

A
  • Pulmonary disease (lung disease)
  • Reccurent infections (repeated infections)
  • Production of thick sputum
  • Hard to digest and absorb food and nutrients due to lack of pancreas function

Other complications include:
- Liver disease
- Osteoporosis
- CF related diabetes (pancreas scarring leads to less insulin produced)

35
Q

What is the treatment Cystic Fibrosis?

A

1st line: Dornase alfa (via nebulisers)

Mannitol dry powder, if Dornase alfa is unsuitable

Antibiotics for lung infections

36
Q

What is a non-pharmacological treatment for cough and congestion?

A
  • Eucalyptus oil
  • Menthol crystals in warm water
