Haloperidol pharmacological properties

When the pharmacologic properties of two compounds are compared, one may prove to be more potent and efficacious than the other. For instance, as an analgesic, morphine is more potent and more efficacious than acetylsalicylic acid. On the other hand, two compounds may be equally efficacious but one could be more potent. Haloperidol and chlorpromazine are both efficacious neuroleptics in the management of schizophrenia, but haloperidol is more potent. 

Thiothixene (2 mg t.i.d. in mild cases) is indicated in the management of psychotic disorders. Thiothixene and chlor-prothixene are thioxanthene antipsychotics. Their select pharmacological properties are compared with chlorprom-azine and haloperidol and are shown in Table 2.
