case:
Kapag nagtake ng diazepam at aspirin together. what happens
Aspirin will be metabolized in the stomach.
increase risk of PUD.
Weak acid+ weak base
Ionized so excreted. Almost all drug are weak acid and weak base. if pinagsama ang acid + base= formation of salt also.
(+) charged + (-) charged
ionization
It is a type of complexation where metal is used.
Chelation
- charged metal
binding of ion
Charged particles bind
