Ethoheptazine is an analgesic, which belongs to the proheptazine group. It was used either alone (Zactane trade name) or in combination with meprobamate and aspirin (Equagesic) for the pain relief in patients with headache or musculoskeletal disorders. Currently all mediactions containing ethoheptazine are withdrawn from the market. The exact target of ethoheptazine is unknow, but it is believed that it may have modulatory effect on opioid receptors.

Ethotoin is a hydantoin derivative and anticonvulsant. Ethotoin exerts an antiepileptic effect without causing general central nervous system depression. The mechanism of action is probably very similar to that of phenytoin. The latter drug appears to stabilize rather than to raise the normal seizure threshold, and to prevent the spread of seizure activity rather than to abolish the primary focus of seizure discharges. Ethotoin inhibits nerve impulses in the motor cortex by lowering sodium ion influx, limiting tetanic stimulation. Ethotoin is used for the control of tonic-clonic (grand mal) and complex partial (psychomotor) seizures. Ethotoin is marketed as Peganone by Ovation.

Glutethimide is a GABA agonist that was introduced by Ciba in 1954 as a safe alternative to barbiturates to treat insomnia. Before long, however, it had become clear that glutethimide was just as likely to cause addiction and caused similarly severe withdrawal symptoms. Glutethimide was discontinued in the US by manufacturers in 1993. Current production levels in the United States point to it only being used in small-scale research.

THIOPROPAZATE, a phenothiazine derivative, is a typical antipsychotic. It is a prodrug to perphenazine.

Deserpidine is an ester alkaloid drug isolated from Rauwolfia canescens (family Apocynaceae) with antipsychotic and antihypertensive properties that has been used for the control of high blood pressure and for the relief of psychotic behavior. Rauwolfia alkaloids work by controlling nerve impulses along certain nerve pathways. As a result, they act on the heart and blood vessels to lower blood pressure. Deserpidine's mechanism of action is through inhibition of the ATP/Mg2+ pump responsible for the sequestering of neurotransmitters into storage vesicles located in the presynaptic neuron. The neurotransmitters that are not sequestered in the storage vesicle are readily metabolized by monoamine oxidase (MAO) causing a reduction in catecholamines.

LEVAMFETAMINE the levorotatory form of amphetamine. L-amphetamine, is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. L-Amphetamine succinate was sold in Hungary between 1952 and 1955 under the brand name Cydril.

PHENAGLYCODOL is a propanediol-type tranquilizer used to treat a variety of nervous conditions and tensions including anxiety and depression. It can lead to gynecomastia and urinary steroid excretion in patients that are treated with the drug.

PECAZINE is a phenothiazine derivative that was used as an antipsychotic. It is also an allosteric inhibitor of MALT1 paracaspase activity.

Propoxyphene is a centrally acting opiate analgesic. Propoxyphene is an odorless, freely soluble in water, white crystalline powder with a bitter taste. In vitro studies demonstrated propoxyphene and the metabolite norpropoxyphene inhibit sodium channels (local anesthetic effect) with norpropoxyphene being approximately 2 fold more potent than propoxyphene and propoxyphene approximately 10 fold more potent than lidocaine. Propoxyphene and norpropoxyphene inhibit the voltage-gated potassium current carried by cardiac rapidly activating delayed rectifier (hERG) channels with approximately equal potency. It is unclear if the effects on ion channels occur within therapeutic dose range. Propoxyphene is indicated for the relief of mild to moderate pain.

METHITURAL (as sodium salt) is a barbiturate derivative which was used as an ultrashort-acting intravenous anesthetic.
