Propiomazine is a typical antipsychotic, blocking H1 receptors and is primarily indicated in conditions Insomnia. Propiomazine was also used under brand name largon for the relief of restlessness and apprehension, preoperatively or during surgery. In addition largon was used as an adjunct to analgesics for the relief of restlessness and apprehension during labor. But this drug was discontinued.

Piminodine is an analog of pethidine. It was used in medicine for obstetric analgesia and in dental procedures briefly during the 1960s and 1970s, but has largely fallen out of clinical use. Piminodine produces analgesia, sedation and euphoria and has typical side effects associated with opioids, including potentially serious respiratory depression, which can be life-threatening. Piminodine was more potent than desipramine and protriptyline under similar conditions. Compared to meperidine, piminodine is more potent and gives smoother duration. Piminodine can be addictive. Piminodine is currently a Schedule II controlled substance in the United States.

Ergonovine (also known as ergometrine) is the active water soluble component of ergot of rye. Ergonovine is being used as a maleate salt to prevent or treate postpartum haemorrhage and postabortion haemorrhage. Ergonovine stimulates alpha-adrenergic and serotonin receptors, thus activating contractions of uterine and vascular smooth muscle. Ergonovine may have depressant effect on CNS system as it binds to dopamine receptors.

Biperiden, sold under the brandname Akineton was used as an adjunct in the therapy of all forms of parkinsonism (postencephalitic, arteriosclerotic and idiopathic). Was also useful in the control of extrapyramidal disorders due to central nervous system drugs such as phenothiazines and other groups of psychotropics. Biperiden is a weak peripheral anticholinergic agent. It has, therefore, some antisecretory, antispasmodic and mydriatic effects. In addition, biperiden possesses nicotinolytic activity. Parkinsonism is thought to result from an imbalance between the excitatory (cholinergic) and inhibitory (dopaminergic) systems in the corpus striatum. The mechanism of action of centrally active anticholinergic drugs such as biperiden is considered to relate to competitive antagonism of acetylcholine at cholinergic receptors in the corpus striatum, which then restores the balance. Atropine-like side effects such as dry mouth; blurred vision; drowsiness; euphoria or disorientation; urinary retention; postural hypotension; constipation; agitation; disturbed behavior may been seen. Only limited pharmacokinetic studies of biperiden in humans are available.

Protokylol, a sympathomimetic drug has been utilized in general clinical practice as a bronchodilator. Protokylol (brand names Caytine, Ventaire) is a β-adrenergic receptor agonist which was used as a bronchodilator in Europe and the United States.

(-)-Phenazocine is an opioid analgesic drug, which is related to pentazocine and has a similar profile of effects. (-)-Phenazocine is a potent mu opioid receptor agonist. In addition, (−)-phenazocine is also known to bind to δ opioid receptors (DOR) and κ opioid receptors (KOR). Regarding their analgesic potency, (−)-phenazocine was twenty times more potent than morphine in the hot plate test and sixty times more potent than its dextro enantiomer when it was subcutaneously (s.c.) administered

Chlorphenoxamine is an antihistamine and anticholinergic used as an antipruritic and was formerly used in the sympathomimetic treatment of parkinsonism. Histamine receptor H1 antagonist. Chlorphenoxamine is used to treat Allergic conditions, it is reported as an ingredient of Systral in Germany, Malta, Portugal, Thailand, Turkey.

Piperilate is an antispasmodic, antimuscarinic agent. It is a muscarinic cholinergic receptor antagonist.

Trimeprazine (also known as Alimemazine), a phenothiazine used as antipsychotic drug. This drug is used in Russia under brand name TERALIGEN and has anti-histamine, sedative, and anti-emetic (anti-nausea) effects. Teraligen is used to treat neurosis, depression and anxiety of different origins. It prevents and relieves allergic conditions, which cause pruritus and urticaria by blocking histamine produced by the body during an allergic reaction. Trimeprazine competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding. Trimeprazine is not approved for use in humans in the United States. Nevertheless, combination of alimemazine and prednisolone (commonly sold under the brand name Temaril-P) is licensed as an antipruritic and antitussive in dogs.
