Etisulergine (CQ 32-084) is an ergoline derivative. Etisulergine stimulates both dopamine D1- and D2-receptors, antagonizes alpha-adrenergic and serotonin 5-HT2 receptors. Etisulergine demonstrated antiparkinsonian activity in patients.

Nomelidine (norzimelidine), the active N-demethylated metabolite of zimelidine, is a potent and specific inhibitor of [14C]5-HT uptake in synaptosome rich homogenates of rat hypothalamus. Nomelidine inhibits the uptake of 5-HT more potently than the parent compound. Zimelidine (ZIM) and its main active metabolite norzimelidine (NZIM) have been shown to preferentially inhibit 5-hydroxytryptamine (5-HT) neuronal uptake both in vitro and in vivo while having much less effect on noradrenaline (NA) uptake.

Nolomirole (CHF1035) is an orally active, selective dopamine agonist, primarily activating DA2- and alpha2 receptors, thereby inhibiting norepinephrine release, which may be beneficial in heart failure. Nolomirole is able to attenuate the heart failure signs in the monocrotaline-induced congestive heart failure. CHF1035 is a mixture of two enantiomers, CHF1800 (+) and CHF1810 (-). CHF1035 and its metabolite CHF1024 significantly decreased the IOP in rabbits, and are potential novel IOP lowering agents. Especially, CHF1035 produced a substantial decrease in IOP for a prolonged period of time, and thus may prove useful in glaucoma therapy. Nolomirole is a pre-synaptic stimulator of DA2-dopaminergic and α2-adrenergic receptors in peripheral sympathetic nerve endings. These receptors act as a negative feedback mechanism, inhibiting norepinephrine secretion. In early phase clinical studies lasting 1–3 months, nolomirole reduced peripheral systemic resistance and 24 hour blood pressure and increased cardiac output. In a study of 29 patients with heart failure, followed for 10 days, a reduction in plasma norepinephrine was demonstrated. In spite of the fact that Nolomirole was in clinical trials for the treatment of heart failure, its development was discontinued.

Pravadoline is the anti-nociceptive agent, which has analgesic efficacy against postoperative pain in humans. Pravadoline inhibits the enzyme cyclooxygenase, but in contrast to cyclooxygenase-inhibiting NSAIDs does not produce gastrointestinal irritation. Pravadoline inhibited the synthesis of prostaglandins in mouse brain both in vitro and ex vivo. Pravadoline demonstrated only weak anti-inflammatory activity relative to its anti-nociceptive potency. Single doses of pravadoline were safe and effective in humans, without serious adverse events. Single oral administration of pravadoline maleate induced acute tubular necrosis in male and female beagle dogs.

Pirandamine is the potential antidepressant drug. It is a relatively selective inhibitor of the serotonin uptake mechanism and does not exhibit appreciable norepinephrine uptake blocking activity in contrast to the tricyclic antidepressant drugs imipramine and amitriptyline. Pirandamine is equivalent to amitriptyline and greater than imipramine in potency as a serotonin uptake blocker and a potentiator of central serotonin pharmacological actions, and in contrast, does not exhibit appreciable central anticholinergic effects. Pirandamine potentiated the behavioral effects of 5-hydroxytryptophan in mice. Pirandamine, in contrast to desimipramine and imipramine, did not prevent reserpine-induced hypothermia. The (-)-enantiomer of pirandamine retained the activity of the racemate; the (+I-enantiomer was much less effective.

Droclidinium is the muscarinic receptors antagonist. It is an anticholinergic, spasmolytic agent.

Valdipromide is an antidepressant.

Alepride is a sulpiride derivative. It is an antiemetic agent.

Nitrazepate is the diazepam derivative. Nitrazepate is tranquiliser.

Pranosal is the analgesic and anti-inflammatory agent. It has been used as the salicylate as a topical analgesic in concentrations of 5% in rheumatic and other disorders.
