Zomepirac Sodium (Zomax) is a pyrrole-acetic acid structurally related to tolmetin sodium. Zomepirac is a prostaglandin synthetase inhibitor and is not an opioid, an opioid antagonist, or a salicylate. Zomepirac was approved by the Food and Drug Administration for marketing in the United States as an analgesic. It was indicated for all forms of mild to moderately severe pain, and was being promoted as a "comprehensive, non-addicting analgesic." Later Zomepirac was found to be associated with fatal and near-fatal anaphylactoid reactions. The manufacturer voluntarily removed Zomax tablets from the Canadian, US, and UK markets in March 1983.

Levomepromazine (also known as methotrimeprazine) is a phenothiazine neuroleptic drug. It is sold in many countries under the generic name (levomepromazine) or under brand names such as Nozinan, Detenler and many more. Levomepromazine is an antipsychotic drug is commonly used as an antiemetic to alleviate nausea and vomiting in palliative care settings particularly in terminal illness. Levomepromazine is a phenothiazine with pharmacological activity similar to that of both chlorpromazine and promethazine. It has the histamine-antagonist properties of the antihistamines together with central nervous system effects resembling those of chlorpromazine. Levomepromazine's antipsychotic effect is largely due to its antagonism of dopamine receptors in the brain. In addition, it can block 5HT2 receptors and some others, like histamine, serotonin.

CHLORAL BETAINE, a chemical complex of chloral hydrate and betaine, is a nonbarbiturate sedative and hypnotic. It is indicated for sleep induction, preoperative sedation, and daytime sedation. CHLORAL BETAINE is converted to chloral hydrate in the body and its action on the central nervous system is identical with that of chloral hydrate.

Pargyline is an irreversible selective monoamine oxidase (MAO)-B inhibitor, which possesses higher selectivity to this isoform in comparison with MAO-A. It was approved under brand name eutonyl for the treatment hypertension, but then this drug was discontinued.

Methaqualone is a depressant that modulates the activity of the GABA receptors in the brain and nervous system. It promotes relaxation, sleepiness and sometimes a feeling of euphoria. It causes a drop in blood pressure and slows the pulse rate. These properties are the reason why it was initially thought to be a useful sedative and anxiolytic. Common side effects of Methaqualone include dizziness, nausea, vomiting, diarrhea, abdominal cramps, fatigue, itching, rashes, sweating, dry mouth, tingling sensation in arms and legs, seizures and its depressant effects include reduced heart rate and respiration. The drug became banned in many countries and was withdrawn from many markets in the early 1980s.

Promazine (Sparine) is a phenothiazine neuroleptic used for short-term management of moderate to severe psychomotor agitation and treatment of agitation and restlessness in the elderly. Promazine is an antagonist at types 1, 2, and 4 dopamine receptors, 5-HT receptor types 2A and 2C, muscarinic receptors 1 through 5, alpha(1)-receptors, and histamine H1-receptors. Promazine's antipsychotic effect is due to antagonism at dopamine and serotonin type 2 receptors, with greater activity at serotonin 5-HT2 receptors than at dopamine type-2 receptors. This may explain the lack of extrapyramidal effects. Promazine does not appear to block dopamine within the tuberoinfundibular tract, explaining the lower incidence of hyperprolactinemia than with typical antipsychotic agents or risperidone. Antagonism at muscarinic receptors, H1-receptors, and alpha(1)-receptors also occurs with promazine. Promazine is not approved for human use in the United States. It is available in the US for veterinary use under the names Promazine and Tranquazine.
