What are the first-generation antipsychotics?

The new terminology calls them first-generation antipsychotics, these include drugs such as chlorpromazine, haloperidol, fluphenazine, among others. The term atypical antipsychotics is the most commonly used for second-generation antipsychotics.

What is a first generation drug?

First-generation ‘typical’ antipsychotics are an older class of antipsychotic than second-generation ‘atypical’ antipsychotics. First-generation antipsychotics are used primarily to treat positive symptoms such as hallucinations and delusions.

Are first-generation antipsychotics anticholinergic?

Anticholinergic effects are especially prominent with weaker-binding first-generation antipsychotics, as well as with the second-generation antipsychotic clozapine.

Are first-generation antipsychotics typical or atypical?

First-generation antipsychotics are dopamine receptor antagonists (DRA) and are known as typical antipsychotics. Second-generation antipsychotics are serotonin-dopamine antagonists and are also known as atypical antipsychotics.

What are side effects of first generation antipsychotics?

First-generation antipsychotics have a high rate of extrapyramidal side effects, including rigidity, bradykinesia, dystonias, tremor, and akathisia. Tardive dyskinesia (TD)—that is, involuntary movements in the face and extremities—is another adverse effect that can occur with first-generation antipsychotics.

Are first generation antipsychotics still used?

First-generation antipsychotics (FGAs) are drugs used primarily for the treatment of schizophrenia and related psychotic disorders. The use of FGAs has declined in the last few years, mainly because of an increase in prescriptions of second-generation agents.

What kind of medication is first generation antipsychotic?

Dopamine is a chemical produced by neurons in the brain, and first-generation antipsychotics are dopamine inhibitors. First-generation antipsychotics, also called traditional or conventional antipsychotics, are a group of antipsychotic medications. These medications were originally used to treat schizophrenia.

How are first generation antipsychotic depots broken down?

All first generation depot antipsychotics are esterified long chain fatty acids contained in a base oil. Once injected the ester bond is gradually broken down releasing active drug into the blood stream. There is little evidence to suggest any significant differences in efficacy between the three available drugs.

What are the side effects of first generation drugs?

Extrapyramidal side effects are common to all first-generation drugs, whereas other, less specific side effects (e.g., sedation, weight gain, postural hypotension) occur with some but not all substances (see Psychopharmacotherapy: Side Effects ). Table 3. Extrapyramidal syndromes induced by first-generation antipsychotic drugs.
