drugs prescribed, usually on a short-term basis, to reduce anxiety

drugs that prevent the destruction of acetylcholine within the parasympathetic nervous system. Increasing acetylcholine slow heart action, lowers blood pressure, increases secretion, and increases contraction of smooth muscles

Second-generation antipsychotics, which commonly interact with serotonin as well as dopamine receptors. They are considered the first line of tx for psychosis and have a low profile for EPS

24-hr bilogical rhythm that influcences specific regulartory functions such as the sleep/wake cycle, body temp, and hormonal and neurotransmitter secretions

First-generation antipsychotics that is a dopamine 2 receptor antagonism. Effective tx of positive symptoms but not negative and is known for EPS

return of neruotransmitters to the presynapitc cell after communication with receptors on the postsynaptic cell

first-line antidepressants that block the reuptake of serotonin, permitting serotonin to act for an extended period at te synapic binding sites in the brain

gap between the membrane of one neuron and themembrane of another neuron

ratio of the therapeutic dose of a drug and the toxic dose of a drug

drugs that inhibit the reuptake of norepinephrine and serotonin by the presynapitc neurons in the CNS, increasing the amount of time norepinephrine and serotonin are available
