Duoperone is a neuroleptic agent. Duoperone blocked d-amphetamine lethality in mice under aggregated conditions when the pretreatment interval was between one hour and seven days. Conditioned avoidance responding in mice and cats was suppressed by duoperone in doses that did not impair escape behavior. Duoperone produced catalepsy in rats. The onset of this effect was delayed and the duration was prolonged when compared with that of chlorpromazine. It was a potent antiemetic agent in dogs, with a delayed onset and prolonged duration of action.

Carabersat is an anticonvulsant devoid of cardiovascular side effects with minimal central nervous system adverse actions. Carabersat does not bind to ion channels, purinergic, aminergic, opioid and other peptidergic receptors. It selectively interacts with its own binding site, which is not yet elucidated. Carabersat has no effect on sodium channels, GABAergic or glutamate pathways. Carabersat had been in phase II clinical trials for the treatment of epilepsy. It has a potential action in preventing migraines because it acts through an inhibition of the cortical spreading depression trigeminal nerve-induced vasodilatation in cats. Its good therapeutic index and the markedly reduced neurological impairments could make it a useful agent for migraine prophylaxis pending efficacy parameters of controlled studies, which are underway.

Deramciclane is camphor derivative. It is an anxiolytic agent that binds with high affinity to 5-HT2A/2C receptor. Deramciclane showed significant evidence of efficacy for the treatment of generalized anxiety disorder in adult patients. A single dose of deramciclane was rapidly absorbed with peak plasma concentrations being reached after about 3 h. Deramciclane has a half-life of around 27 h. The most commonly reported adverse event was headache. In the in vitro studies deramciclane concentration-dependently inhibited NMDA evoked spreading depression.

Lometraline is a tranquillizer and anti-parkinsonian drug. It was developed as an antidepressant agent. Lometraline is a congener of popular antidepressant (+)-sertraline.

Dimesone is a synthetic glucocorticoid with anti-inflammatory and anti-allergic activity.

Somantadine, an adamantane derivative, is an antiviral agent. Somantadine was synthesized by Pennwalt and has been undergoing tests for the treatment of herpes virus for nearly five years.

Sodium nivimedone (BRL10833) is an orally administered anti-allergic agent with similar properties to DSCG. Nivimedone inhibited IgE-mediated passive cutaneous anaphylactic (PCA) reactions in the rat and the antigen-induced release of histamine from human lung passively sensitized with atopic serum. The pharmacological potency of sodium nivimedone when compared to DSCG was 42 times greater in the human lung system and approximately ten times greater in rat PCA. In addition, single doses of sodium nivimedone given by mouth inhibited antigen-induced bronchoconstriction in man.

Emilium is an antiarrhythmic agent and cardiac depressant.

Metalkonium is an antiseptic and disinfectant.
