Oxantel is a narrow-spectrum anthelmintic effective against whipworms in dogs and cats. It is ineffective against other roundworms, flukes, tapeworms or external parasites. Oxantel acts on the nervous system of the worms as inhibitors of acetylcholinesterase. Oxantel, a cholinergic anthelmintic and fumarate reductase inhibitor, significantly inhibited biofilm formation by P. gingivalis and disrupted established biofilms at concentrations below its MIC against planktonic cells. Oxantel was more effective against P. gingivalis in biofilm than metronidazole, a commonly used antibiotic for periodontitis. When oxantel was administrated to human beings for the treatment of trichuriasis, no drug reaction or side effects were reported, and the results of hematologic, biochemical and urinary examinations didn’t reveal any significant drug-related changes.

Roxatidine is an histamine H2-receptor antagonist. Roxatidine is a potent and selective inhibitor of basal and stimulated gastric acid secretion through competitive blockade of H2-receptors. Total pepsin secretion is reduced in a dose-dependent manner. There is an independent mucosal protection action. Roxatidine is indicated for the treatment of peptic ulcer, gastro-oesophageal reflux disease, gastritis, upper gastrointestinal haemorrhage and Zollinger-Ellison syndrome also it can be used as a premedication before anaesthesia. Roxatidine possessed a robust estrogenic activity.

Zacopride is a potent antagonist at the 5-HT3 receptor and an agonist at the 5-HT4 receptor with antiemetic, anxiolytic and nootropic effects in animal models. Zacopride also has pro-respiratory effects, both reducing sleep apnea and reversing opioid-induced respiratory depression in animal studies. Zacopride has been tested in clinical trials for the treatment of schizophrenia but was found unsuccessful.

Zinterol (MJ-9184-1) is an beta-adregenrgic agonist demostrated activity toward beta1-3 receptors. Oral zinterol caused a fast-appearing and long-lasting bronchodilator effect in patients with with stable chronic obstructive lung disease, however it seems development of zinterol was discontitued.

Butamisole is an injectable imidazothiazoles anthelmintic. In dogs it is used for the treatment of infections with whipworms (Trichuris vulpis ), and the hookworm (Ancylostoma caninum ). Nicotinic acetylcholine receptor agonist. Acts as agonist at nicotinic Ach receptor of nematode à ganglionic stimulation causes sustained muscle contraction initially followed by depolarising neuro muscular blockade which in turn leads to spastic paralysis.

Eptazocine is an opioid analgesic which was introduced in 1987 by Morishita in Japan . It acts as a mixed κappa opioid receptor agonist and mu-opioid receptor antagonist.

Fabomotizole (also known as Afobazole) is a selective non-benzodiazepine anxiolytic which was developed in Russia and launched in 2006. The drug is used for the treatment of wide range of diseases: generalized anxious disorders, neurasthenia, adaptation disorders, sleep disorders, for alleviation of withdrawal syndrome. According to the drug label (in Russian), its action is related to the interaction with sigma-1 receptors.

Dextromoramide is a synthetic strong-acting opioid and full mu-opioid receptor agonist. Dextromoramide is a Schedule I drug illegal to possess. The current indication for Palfium® (dextromoramide) is severe acute or chronic pain requiring opioids, such as post-operative pain, and pain associated with bone fractures, malignancies and acute renal/biliary colic attacks in adults.

Fenbutrazate is a prodrug of phenmetrazine, a psychostimulant for the treatment of obesity. Fenbutrazate acts as an agonist of monoamine transportes upon conversion to the active metabolite. The drug is no longer marketed due to its addictive profile.

Bambuterol is an active precursor of the selective beta2-adrenergic agonist terbutaline. Bambuterol is the bis-N,N-dimethyl-carbamate of terbutaline. Bambuterol is a remarkably selective and potent inhibitor of cholinesterase. BAMBEC (Bambuterol hydrochloride) oral solution or tablets are indicated for the management of asthma, bronchospasm and/or reversible airways obstruction.
