18
Q

Mast cell stabilizers include

A

Nedocromil
Cromolyn

19
Q

What reduces FEV1?

A

Inflammation enzymes

Histamine
Prostaglandin
Trypase
Leucotrine
Platelet activating factor

20
Q

What is FEV??

A

This is also called forced expiratory volume

The amount of air one can exhale after a forced inspiration

21
Q

Non selective adrenoreceptor drugs in asthma treatment is

A

Epinephrine
Ephedrine

22
Q

What is the side effect of using epinephrine in treating asthma

A

Epinephrine binds to both alpha and beta blockers

It can bind to beta 1 and cause tachycardia, arrhythmia, worsen angina pectoris

23
Q

Non selective beta agonist

Salbutamol
Caffeine
Isoproterenol
Levabuterol
Loperamide

A

Isoproterenol / isoprenaline

24
Q

Beta 2 agonist mechanism of action on treating asthma

A

They activate adenyl cyclase which increases Camp causing bronchodilatoin

25
Q

29
Q

Anticholinergices include

A
