Understand the general concepts of pharmacokinetics and pharmacodynamics
Be able to discuss for the four components of pharmacokinetic
Absorption
Distribution
Metabolism
Inducer
Inhibitor- causes other drugs to back up; increase in levels
Excretion
How can alteration or disruption of any of these components change the
pharmacokinetics of a drug?
Be able to recognize the implications of highly bound drugs and altered protein binding
Understand CYP450 enzymes and be able to differentiate what can happen in drug-
drug interactions due to inhibition and induction
Know what lab value can be used to determine renal excretion (CrCl, GFR)
Compare and contrast the sympathetic and parasympathetic divisions of the ANS.
Identify the neurotransmitters and receptors associated with each, and the effects of
these neurotransmitters on organs and tissues
Describe the mechanisms of action of the following classes of drugs (be specific with
respect to the receptor type involved, if any)
o Indirect-acting cholinomimetics (acetylcholinase inhibitor) – pyridostigmine
o Direct-acting cholinomimetics – bethanechol
o Cholinergic antagonists – atropine (1st line drug for bradycardia), oxybutynin

← Be able to identify potential causes of asthma (drug induced!)
← Describe the mechanism of action for the respiratory drugs and know any
adverse effects associated with the class(boxed warnings)
Bronchodilators
o Beta-adrenergic agonists – albuterol, levalbuterol, arformoterol,
salmeterol
o Anticholinergics – Ipratropium bromide, tiotropium
