5
Q

Describe how TYPICAL antipsychotic drugs work

A

Typical antipsychotics are used to treat positive symptoms in SZ such as Hallunications. They were the original antipsychotics and are conventional, first generation drugs. They do this by working as dopamine antagonists so they block receptors- particularly D2 receptors but do not stimulate dopamine receptors. They reduce the stimulation of the dopamine system in the Mesolimbic dopamine lath way

6
Q

Describe how atypical antipsychotic drugs work

A

Second generation antipsychotics were made in order to prevent as serious extrapyramidenal side effects. They work by temporarily blocking the D2 receptors and the dissociate to allow normal dopamine transmission. They also have an effect on serotonin- with serotonin also being an inhibitory nerve.

1952

8
Q

What study supports the effectiveness of antipsychotics?
