Term
TD50
Definition
The dose at which 50% pts experience toxicity (side effects)
Term

TI (therapeutic index)
Definition

TD50/ED50

 

higher index-wider and better window

lower index- smaller and worse window

Term
Agonists
Definition

D+R<-->DR<--> DR*

 

 

Term
Full agonists
Definition
Elicits maximal response and stabalizes DR*
Term
Partial/Mixed agonists-antagonists
Definition
stabilizes Dr and DR*
Term
Inverse agonists
Definition

Receptors that are active naturally are made inactive

 

stablizes DR in the case of R*

Term
Antagonists
Definition

inhibits agonist activity

stabalization of DR, prevention of DR*

 

Term

Definition
reversible binding, can be bumped 
Term
Noncompetitive Antagonist
Definition
irreversible binding to active site or allosteric site, cant be bumped
