Chlorpromazine pamoate (also known as chlorpromazine embonate) is a salt of pamoic acid and a chlorpromazine. Pamoate salts are used in pharmaceutical formulations because they show slow dissolution and are useful in formulations where extended duration of action is required. Chlorpromazine is a phenothiazine antipsychotic. It also exerts sedative and antiemetic activity. The precise mechanism whereby the therapeutic effects of chlorpromazine are produced is not known. It has a wide range of activity arising from its depressant actions on the CNS and its alpha-adrenergic blocking and antimuscarinic activities. Chlorpromazine is a dopamine inhibitor; the turnover of dopamine in the brain is also increased. There is some evidence that the antagonism of central dopaminergic function, especially at the D2-dopaminergic receptor, is related to therapeutic effect in psychotic conditions.

Sulpiride is an atypical antipsychotic drug (although some texts have referred to it as a typical antipsychotic) of the benzamide class used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder, and sometimes used in low dosage to treat anxiety and mild depression. Sulpiride is commonly used in Europe, Russia and Japan. Sulpiride is a selective antagonist at dopamine D2 and D3 receptors. This action dominates in doses exceeding 600 mg daily. In doses of 600 to 1,600 mg sulpiride shows mild sedating and antipsychotic activity. Its antipsychotic potency compared to chlorpromazine is only 0.2 (1/5). In low doses (in particular 50 to 200 mg daily) its prominent feature is antagonism of presynaptic inhibitory dopamine receptors accounting for some antidepressant activity and a stimulating effect. Therefore, it is in these doses used as a second line antidepressant. Racemic and L-sulpiride significantly decreased stimulated serum gastrin concentration, but they did not affect fasting serum gastrin or basal and stimulated gastric acidity. D-sulpiride significantly decreased gastric acid secretion, without affecting serum gastrin levels.

Zacopride is a potent antagonist at the 5-HT3 receptor and an agonist at the 5-HT4 receptor with antiemetic, anxiolytic and nootropic effects in animal models. Zacopride also has pro-respiratory effects, both reducing sleep apnea and reversing opioid-induced respiratory depression in animal studies. Zacopride has been tested in clinical trials for the treatment of schizophrenia but was found unsuccessful.

Sodium anthranilate is an excipient (pharmacologically inactive substance). Sodium anthranilate (Aminobenzoate sodium ,C7H6NNaO2), also known as sodium 2-aminobenzoate, is an organic amine. Aminobenzoate sodium exists as a yellow powder for use in pharmaceutical processing.

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.

Clocapramine is a chlorinated derivative of carpipramine. The hydrochloride has been given orally in the treatment of schizophrenia. Clocapramine is an antagonist of the Dopamine D2 and Serotonine (5-HT2) receptors. It has been implicated in at least one strange death, including a suicide. It augments the paroxetine in the panic disorder treatment.

Huperzine A is a plant alkaloid derived from Club moss plant, Huperzine serrata, which is a member or the Lycopodium species. Huperzine-A is in phase III clinical trial in the USA (Alzheimer disease) and is available as a dietary supplement. It selectively and reversibly inhibits acetylcholinesterase. Huperzine A is also a NMDA receptor antagonist, which protects the brain against glutamate induced damage, and it increases nerve growth factor levels. Huperzine A is used for Alzheimer's disease, memory and learning enhancement, and age-related memory impairment. It is also used for treating a muscle disease called myasthenia gravis, for increasing alertness and energy, and for protecting against agents that damage the nerves such as nerve gases. It can cause some side effects including nausea, diarrhea, vomiting, sweating, blurred vision, slurred speech, restlessness, loss of appetite, contraction and twitching of muscle fibers, cramping, increased saliva and urine, inability to control urination, high blood pressure, and slowed heart rate. Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs) interacts with Huperzine A.

Moperone is a first-generation (typical) antipsychotic drug that belongs to the butyrophenone type approved in Japan for the treatment of schizophrenia. It has higher antagonist affinity for D2- than 5-HT2A-receptors. It also has high binding affinity for sigma receptors. It was indicated for schizophrenia, paranoid state, psychoses, epilepsy,alcohol withdrawal syndrome. It can induce extrapyramidal motor side effects, insomnia, and thirst, but it displays generally low toxicity.

Setiptiline Maleate is a tetracyclic antidepressant that has been used in the treatment of depression. It has antihistamine and hypnotic–sedative effects, but almost no anticholinergic effects. It is a weak inhibitor of norepinephrine reuptake in vitro and strongly stimulates the release of central norepinephrine by blocking presynaptic α2-adrenoceptors similar to mianserin. It also acts as a 5-HT2A, 5-HT2C, and 5-HT3 receptor antagonist. Unlike most conventional antidepressants, it has no efficacy as a serotonin reuptake inhibitor. It can induce drowsiness and thirst, but it displays low toxicity. Setiptiline Maleate was launched in 1989 for the treatment of depression in Japan.

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.
