Q

MOA of Varenicline (Chantix)

A

Non-nicotine cessation aid, partial nicotinic receptor agonist.

Binds with high affinity and selectivity at a4b2 neuronal nicotinic acetylcholine receptors: stimulates low-level agonist activity, competitively inhibits binding of nicotine

Clinical effects: Symptoms of nicotine withdrawal, blocks dopaminergic stimulation responsible for reinforcement & reward associated with smoking

COPD
69
MOA of Tiotroprium (Spiriva)
Long acting anticholinergic Blocks M3 receptors that lead to bronchial smooth muscle constriction Allows for bronchodilation, slower than alpha agonist
70
MOA of Glycopyrrolate and Aclidinium? *newer inhalers*
Anticholinergics
71
Why are Anticholinergics used in pt's which airway problems?
Release of acetylcholine from parasympathetic nerves activates postjunctional muscarinic receptors present on airway smooth muscle, submucosal glands, and blood vessels to cause bronchoconstriction, mucus secretion, and vasodilatation, respectively. ... These changes are due to increased parasympathetic nerve activity.
