B2 Flashcards
ligand definition
anything that binds to a receptor to form a complex
docking
how receptors bind to ligands
affinity
how much a drug likes a receptor
association
process that binds ligand and receptor together
dissociation
process that releases the ligand and the receptor from eachother
dissociation constant
reaction speed of dissociation - reaction speed of association
continuous dose curves
either linear or semilogarithmic
as you increase the dose, more receptors become occupied
ec-50
dose required to reach 50% of drug efficacy
potency
a measure of the activity of the drug
fentanyl is more potent that morphine
morphine is more potent than meperidine
efficacy
shows the depth of effect
quantal dose response curves
ED50
TD50
LD50
ED 50
effective dose 50
dose that acheives an effect in 50% of the population
td 50
dose that shows side effects in 50% of the population
LD50
when 50% of the population die due to overdose
Ti
ratio between the LD50 and ED 50
