SGA D2 and 5HT2 antagonism causes?
______ competes with medication so not all D2 receptors are attached to medication
reduce risk of EPS because blocking 5HT2A causes DA release
DA
(prevents EPS because there isn't chronic and complete D2 blocking

Choosing the right Pharm tx
What else to consider?
familarize yourself with the receptors and fxn
determine which sx you want to address
find a match between what you are looking to target and the medication's properties
