Penfluridol is a highly potent; first generation diphenylbutylpiperidine antipsychotic was developed by Janssen Pharmaceutica in 1968 and is used to treat schizophrenial and similar psychotic disorders. It is, however, like most typical antipsychotics, being increasingly replaced by the atypical antipsychotics. This drug is long-acting dopamine receptor blocker.

Roxindole (EMD-49,980) is a dopaminergic and serotonergic drug which was originally developed for the treatment of schizophrenia. Roxindole has also been investigated as a therapy for the major depressive disorder, Parkinson's disease, and prolactinoma. Roxindole is dopamine autoreceptor-selective agonistic drug with high affinity to D2-like receptors and with much lower affinities to D1-like, % and ol2, muscarinic and 5HT 2 receptors. Additionally, Roxindole exerts 5HT uptake inhibition and 5HT1A agonistic effects. The bioavailability of Roxindole has been estimated at 5% due to a high first-pass metabolization. On the other hand, in 14C distribution studies, Roxindole has crossed the blood-brain barrier readily and the brain concentrations at all intervals have been much higher than corresponding plasma levels. In clinical trials, Roxindole ‘s antipsychotic efficacy was only modest but it was unexpectedly found to produce potent and rapid antidepressant and anxiolytic effects. However, the clinical development of Roxindole was discontinued.

YM-435 is a dopamine D1 agonist. The renal and cardiovascular effects of YM-435 may be suitable for the treatment of patients with renal insufficiency, heart failure and hypertension. It has been in phase II clinical trials for the treatment of heart failure and hypertension. YM435 may be useful in the preservation of renal function in ischemia-induced acute renal failure. Also, it might be a useful as therapeutic agent for the treatment of congestive heart failure.

Perazine (Taxilan) is a moderate-potency typical antipsychotic of the phenothiazine class. Perazine is an older antipsychotic drug first introduced in the 1950s. It is suggested to have a low level of side effects (especially for movement disorders). Its use is regional and restricted to countries like Germany, Poland, the Netherlands and the former Yugoslavia. Perazine has being shown to be a potent inhibitor of human CYP1A2. It acts as a dopamine antagonist.

Alentemol (U-66444B) is a selective dopamine agonist acting at presynaptic receptors to inhibit the release of dopamine. In preclinical studies the compound caused hypothermia in mice and inhibited amphetamine-stimulated omtor activity in mice. U-66444B was investigated by Upjohn Company for the treatment of schizophrenia, but the development of the drug was discontinued.

Dopexamine hydrochloride is a synthetic catecholamine, structurally related to dopamine, with marked intrinsic agonist activity at beta 2-adrenoceptors, lesser agonist activity at dopamine DA1- and DA2-receptors and beta 1-adrenoceptors, and an inhibitory action on the neuronal catecholamine uptake mechanism. The drug is administered by intravenous infusion, and is characterized by a rapid onset and short duration of action. Dopexamine is being tested as a treatment for heart failure and sepsis.

Levosulpiride [RV 12309, L-sulpiride, levosulpride, Dislep® 25, Levopride®, Levopraid®] is a potent dopamine D2 receptor blocker that was originated by Ravizza Farmaceutici (now AbbVie). Levosulpiride is the levo enantiomer of sulpiride. The levo enantiomer shows better/similar pharmacological actions and lower incidence of toxic effects than both dextro as well as the racemic forms of the drug. Levosulpiride is marketed in Italy and South Korea, and is possibly available elsewhere in Europe and Asia. Levosulpiride does not appear to be available in North America. Levosulpiride is available as 25mg tablets, drops and in ampoules for parenteral administration. Generic versions of levosulpiride also appear to be available in some countries. Levosulpiride is primarily indicated in conditions like Anxiety, Depression, Gastro-esophageal reflux disease, Irritable bowel syndrome, Schizophrenia, Tourette's syndrome, dyspeptic syndrome, essential cephalgia, and can also be given in adjunctive therapy as an alternative drug of choice in Peptic ulcer, Vertigo.

Botiacrine is the antiparkinsonian agent.

Clebopride is a dopamine antagonist drug. It is used to treat functional gastrointestinal disorder such as nausea or vomiting. Unchanged parent drug was the most abundant compound in human urine. Major metabolites included the hydroxylation at benzyl group to yield carbinolamine and its further N-dealkylation product, and the piperidine ring hydroxylation/oxidation metabolite (a lactam).

Bromopride is a dopamine D2 receptor blocker. Bromopride exerts is a gastrointestinal prokinetic exploited clinically for the management of motor disorders of the upper gastrointestinal tract, including functional dyspepsia, gastric stasis of various origins and emesis.
