Study Notes

Tricyclic Antidepressants

Increase norepinephrine and serotonin levels, while blocking acetylcholine action.
Alleviate depression by restoring neurotransmitter balance.

Antidepressants

Used to prevent or treat depression and mood disorders.
Increase levels of excitatory neurotransmitters in the brain.

Antipsychotics

Treat psychosis and bipolar disorder.
Block receptors in dopamine pathways and target various receptors.

Sedative-Hypnotics

Induce sedation and sleep by depressing the central nervous system.

Anticonvulsants

Treat epileptic seizures by suppressing excessive neuron firing.

Antiparkinsons

Relieve Parkinson's disease symptoms.
Increase dopamine activity or reduce acetylcholine activity in the central nervous system.

Tricyclic Antidepressants Examples

Elavil, Pamelor (nortriptyline), Vivactil (protriptyline), Trofranil (imipramine).

Monoamine Oxidase Inhibitors (MAOIs)

Block monoamine oxidase action to accumulate monoamines like norepinephrine.

MAO Inhibitors Examples

Marplan (osocarboxazid), Nardil (phenelzine), Parnate (tranylcypromine).

Selective Serotonin Reuptake Inhibitors (SSRIs)

Allow serotonin neurotransmitter to be used more effectively.

SSRIs Examples

Prozac, Paxil, Zoloft, Celexa, Lexapro, Luvox (fluvoxamine).

Miscellaneous Antidepressants

Examples include Serzone (nefazodone), Desyrel, Effexor, Wellbutrin (Zyban), Remeron.

Low Potency Conventional Antipsychotics

Developed in the 1950s, primarily used for psychosis treatment.

Low Potency Conventional Antipsychotics Examples

Thorazine (chlorpromazine), Mellaril (thioridazine).

Intermediate Potency Conventional Antipsychotics Examples

Trilafon (perphenazine), Loxitane (loxapine).

High Potency Conventional Antipsychotics Examples

Stelazine (trifluoperazine), Prolixin (fluphenazine), Navane (thiothixene), Haldol (haloperidol).

Atypical Antipsychotics

Function differently from conventional antipsychotics, targeting serotonin and dopamine receptors.

Atypical Antipsychotics Examples

Clozaril (clozapine), Zyprexa (olanzepine), Risperdal (risperidone), Seroquel, Geodon (ziprasidone), Abilify.

Benzodiazepines

Relieve nervousness and tension by slowing the central nervous system.

Benzodiazepines Examples

Xanax, Valium, Ativan, Serax (oxazepam), Prosom (estazolam), Restoril.

Nonbenzodiazepines

Psychoactive drugs with actions similar to benzodiazepines but chemically distinct.

Nonbenzodiazepines Examples

Buspar, Ambien, Sonata (zaleplon), Aquachloral (chloral hydrate).

Barbiturates

Class of sedative-hypnotics that depress the central nervous system for various therapeutic uses.
