CV-205502 (Quinagolide, Norprolac), a small molecule, dopamine 2-receptor agonist was developed by Novartis for the treatment of prolactinoma and hyperprolactinaemia. It is is a long-acting dopamine agonist with potent D2 and weak D1 activity. Quinagolide exists as a racemate and its relevant clinical activity is mediated predominantly by the (-) enantiomer. It is typically present in the hydrochloride salt form and is marketed as oral tablets under the brand name Norprolac contained as a racemate. Quinagolide is currently available in several countries including Canada, but not approved for treatment in the United States. Owing to its dopaminergic action, the drug exerts a strong inhibitory effect on the secretion of the anterior pituitary hormone prolactin, but does not reduce normal levels of other pituitary hormones. Long-term treatment with Norprolac was found to reduce the size or limit the growth of prolactin-secreting pituitary macroadenomas. In some patients the reduction of prolactin secretion may be accompanied by short- lasting, small increases in plasma growth hormone levels, the clinical significance of which is unknown. As a specific inhibitor of prolactin secretion with a prolonged duration of action, Norprolac has been shown to be effective and suitable for once-a- day oral treatment of patients presenting with hyperprolactinaemia and its clinical manifestations such as galactorrhoea, oligomenorrhoea, amenorrhoea, infertility and reduced libido.
Talipexole is a D2 receptor agonist which was marketed in June 1996 in Japan for the treatment of Parkinson's disease. Clinical trials with talipexole in patients with Parkinson's disease demonstrated statistically significant improvements from baseline for parkinsonian symptoms including akinesia, rigidity, tremor and gait disturbances.

Pipotiazine (Piportil), also known as Pipothiazine, is a typical antipsychotic of the phenothiazine class used in the United Kingdom and other countries for the treatment of schizophrenia. Its properties are similar to those of chlorpromazine. Piportil® L4 (pipotiazine palmitate) is the palmitic ester of pipotiazine, a piperidine phenothiazine with antipsychotic properties and weak sedative activity. The esterification of pipotiazine is responsible for its prolonged duration of action. The onset of action appears usually within the first 2 to 3 days after injection and the effects of the drug on psychotic symptoms are significant within one week. Improvement in symptomatology lasts from 3 to 6 weeks, but adequate control may frequently be maintained with one injection every 4 weeks. However, in view of the variations in individual response, careful supervision is required throughout treatment. Piportil L4 has actions similar to those of other phenothiazines. Among the different phenothiazine derivatives, Piportil L4 appears to be less sedating and to have a weak propensity for causing hypotension or potentiating the effects of CNS depressants and anesthetics. However, it produces a high incidence of extrapyramidal reactions.

Propionylpromazine is used as a neuroleptic to combat stress in pets and farm animals. The main use is to combat stress in the transport of pigs. Propionylpromazine was in common use in veterinary practice in the 1950s and 1960s. Propionylpromazine is of interest to JECFA because of the illicit use at pharmacological dosage (< 1 mg/kg i.m.) in the immediate pre-slaughter period.

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.
Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 / dopamine D2 blocking activity. It is not available in the US but marketed in other countries for prophylaxis of a migraine, occlusive peripheral vascular disease, the vertigo of central and peripheral origin, motion sickness and as an adjuvant in the therapy of epilepsy. The drug is also investigated for the treatment of schizophrenia.
Trifluperidol is an antipsychotic butyrophenone derivative. It is a high-affinity sigma receptor blocker and it was strongly selective for NR1a/2B receptors. It exhibit pharmacological effects and a mechanism of action very similar to that of phenothiazines and thioxanthenes in that it blocks dopaminergic receptors. It is more selective with respect to D2 receptors. Trifluperidol is indicated for the treatment of acute and chronic schizophrenia, mania and hypomania, organic psychoses, childhood behavioral disorders, agitation in psychotic illness and motor tics. Trifluperidol has been suspected as a cause of cataract in Japan. Patients receiving trifluperidol treatment may develop a parkinsonian-like syndrome which responds to withdrawal of the drug or concurrent administration of an anti-parkinsonian drug. Acute dystonias and akathisia are other acute extrapyramidal effects; tardive dyskinesia may supervene after longer periods of treatment.
Opipramol (Insidon, Pramolan, Ensidon, Oprimol) is an antidepressant and anxiolytic used in Germany and other European countries. Although it is a member of the tricyclic antidepressants, opipramol's primary mechanism of action is much different in comparison, it doesn’t represent a tricyclic antidepressant drug as it does not inhibit the neuronal uptake of norepinephrine and/or serotonin. Opipramol also acts as a low to moderate affinity antagonist for the D2, 5-HT2, H1, H2, and muscarinic acetylcholine receptors. H1 and H2 receptor antagonism account for its antihistamine effects, and muscarinic acetylcholine receptor antagonism is responsible for its anticholinergic properties. Opipramol was developed by Schindler and Blattner in 1961. Opipramol is typically used in the treatment of generalized anxiety disorder (GAD) and somatoform disorders. Its anxiolysis becomes prominent after only one to two weeks of chronic administration. Upon first commencing treatment, opipramol is rather sedating in nature due to its antihistamine properties, but this effect becomes less prominent with time. The therapy with Opipramol indicates an additional therapy with neuroleptics, hypnotics and tranquilizers (e.g. Barbiturates, Benzodiazepines). Therefore, it should be noted that some specific reactions, particularly CNS depressant effects could be intensified and an intensification of common side effects may occur. If necessary the dosage may be reduced. Co-administration with alcohol can cause stupor. MAO Inhibitors should be discontinued at least 14 days before the treatment with Opipramol. Concomitant use of Opipramol with β-blockers, antiarrhythmics (of class 1c), as well as drugs from tricyclic antidepressant group and preparations which influence the microsomal enzyme system, can lead to change in plasma concentration of these drugs. Co-administration of neuroleptics (example- haloperidol, risperidone) can increase the plasma concentration.
cis-Dosulepin is a stereoisomer of Dothiepin (trade name Prothiaden, Dothep, Thaden, and Dopress; Dosulepin (INN, BAN) a tricyclic antidepressant that is used in several European and South Asian countries, as well as Australia, South Africa, and New Zealand. Dosulepin is used for the treatment of the major depressive disorder and neuropathic pain. Dosulepin is only Therapeutic Goods Administration and Medicines and Healthcare products Regulatory Agency approved for the treatment of the major depressive disorder. Dothiepin is not used in the United States. The central action of cis-dosulepin was compared with that of its antidepressant stereoisomer trans-dosulepin, cis-dosulepin exerted weaker anti-reserpine, anti-tetrabenazine, and 3H-5-HT (serotonin) uptake inhibiting actions than trans-dosulepin, but cis-dosulepin's inhibition of 3H-dopamine and 3H-norepinephrine uptake was slightly more potent than that of trans-dosulepin. On the other hand, cis-dosulepin exhibited extremely potent anticholinergic action in oxotremorine induced tremor, isolated ileum and the 3H-quinuclidinyl benzilate binding test. It also showed potent apomorphine enhancing the action and shortened the period of immobility in the forced swimming test in animals.

Thioproperazine is a potent neuroleptic with antipsychotic properties. Thioproperazine has a marked cataleptic and antiapomorphine activity associated with relatively slight sedative, hypothermic and spasmolytic effects. It is virtually without antiserotonin and hypotensive action and has no antihistaminic property. It is used for the treatment of all types of acute and chronic schizophrenia, including those which did not respond to the usual neuroleptics; manic syndromes. Overdosage may result in severe extrapyramidal symptoms with dysphagia, marked sialorrhea, persistent and rapidly increasing hyperthermia, pulmonary syndrome, state of shock with pallor and profuse sweating, which may be followed by collapse and coma.
