Drugs with the fastest onsets include haloperidol, risperidone, and olanzapine, with onsets appearing in 2 6 days. Chlorpromazine and thiothixene were at the slowest end of the continuum, with onsets of 2 weeks or longer.
Among typical antipsychotics, haloperidol is the drug of choice in the rapid tranquilization setting. Another option is zuclopenthixol acetate, another high potency typical agent. Compared to haloperidol, it has a longer duration of action (48-72 hours) and a longer and less predictable onset.

Chlorpromazine was the first antipsychotic and was followed by a large number of other antipsychotics, many with diverse chemical structures. However, so far, no antipsychotic has been shown to be significantly more effective than chlorpromazine in treating schizophrenia with the notable exception of clozapine.
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
The main study findings, from this population-wide head-to-head comparison of thirty-seven antipsychotics, is that zuclopenthixol showed the strongest association with sedation and somnolence while prochloperazine resulted in the weakest association.
Atypical antipsychotics such as quetiapine, aripiprazole, olanzapine, and risperidone have been shown to be helpful in addressing a range of anxiety and depressive symptoms in individuals with schizophrenia and schizoaffective disorders, and have since been used in the treatment of a range of mood and anxiety disorders ...

Conclusion: Atypical antipsychotics such as risperidone, ziprasidone, and olanzapine with or without benzodiazepines should be considered first in the treatment of acute agitation. If these agents are not available the combination of a classic antipsychotic and a benzodiazepine would be a reasonable alternative.

Examples of high potency antipsychotic medications are fluphenazine, trifluoperazine and haloperidol. They have a large side effect profile and can lead to extrapyramidal symptoms and neuroleptic malignant syndrome. Extrapyramidal symptoms observed with administration of these drugs can evolve over time.
Selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) SSRIs and SNRIs are often the first-line treatment for anxiety. Common SSRI brands are Celexa, Lexapro, Luvox, Paxil, and Zoloft.
Categories named included the patient's past treatment response, side effects, intended route of administration and co-morbidities. Moreover, psychiatrists strongly take the patient's target symptoms and the assumed efficacy of certain compounds into account in their choice of medication.
High quality evidence shows a lower risk of extrapyramidal (movement) side effects with benzodiazepines than with antipsychotics. Moderate quality evidence shows benzodiazepines were associated with a faster rate of sedation and more improvement in global state than antipsychotics.
Newer medications, called atypical antipsychotics, are also effective in relieving the symptoms of schizophrenia. These medications, including quetiapine, risperidone, and aripiprazole, are generally prescribed because they pose a lower risk of certain serious side effects than conventional antipsychotics.
