What type of drug is Montelukast?
A leukotriene receptor antagonist
What are pressured metered dose inhalers (pMDI’s)?
Deep exhale, inhale and then hold breath inhalers
How does Salbutamol work?
It binds to beta-2 receptors in the lungs and causes relaxation
What is Salbutamol used to treat?
Asthma and COPD
How long does Salbutamol work for?
Immediately and then lasts 3-5 hours (SAMA)
How long does Salmeterol work for?
Works after 2-30 min and then lasts 10-12 hours (LAMA)
How long does Formoterol work for?
Immediately and then lasts 10-12 hours (LAMA). Similar to Salbutamol
How long does Tiotropium work for?
24 hours
What is the therapeutic effect behind Triotrpium?
It inhibits M3 receptors and causes bronchodilation
How long does Ipratropium work for?
Onset is 30min and then lasts for 6 hours. It’s nebulised for acute presentation of COPD
How long does Theophylline work for?
Half life of 5 hours
What is Theophylline used for?
Persistent asthma and COPD. It’s a phosphodiesterase inhibitor
Beclomethasone, Fluticasone, and budesonide are types of which drug class?
Inhaled glucocorticoids
How do glucocorticoids work?
They decrease release of inflammatory mediators, decrease airway oedema, decrease music production, increase beta-1 sensitivity and number
What are some adverse effects of glucocorticoids?
Adrenal suppression, bone loss, diabetes, hypertension, increase risk of cataracts and glaucoma
What are ICS combined with?
LABA or LAMA
What are LAMA coupled with?
LABA
What does the drug Doxycycline (a Tetracycline) used for?
