MISC Flashcards
Pharmacodynamics
Effect of drug in the body
Relationship between the concentration of drug at the site of action and effect
Efficacy
term to describe the maximum response produced by a drug
Potency
concentration (EC 50) or dose (ED50) that is required to produce 50% of the drugs maximum effect
Agonist
Activates a receptor to produce a response
Antagonist
Has receptor affinity but no efficacy and can prevent agonists from activating a response
Pharmacokinetics
What body does to drug
Process includes ADME
Processes determine the relationship between drug dose and its concentration at the site of action
Bioavailability
Fraction of the dose that reaches the systemic circulation from the site of the dose administration
What does MESS stand for
Mechanism, Evidence, Severity, Symptoms
4 pillars of QUM
Safety, efficacy judiciousness, appropriateness
Category A
No proven increase in frequency of malformations
Category B
B1- only taken by limited number, no increase in frequency of malformation (animal studies shown no evidence)
B2- only taken by limited number, no increase in frequency of malformation (animal studies lacking)
B3- limited number, no increase (animal studies shown evidence of damage)
Category C
drugs have caused or suspected cause of harmful effects (reversible)
Category D
drugs have caused or suspected cause of increased harm (irreversible)
