Piperylone is a non-narcotic analgesic and antispasmodic agent.

The phthalidyl thiazolidine carboxylic ester of ampicillin, talampicillin (Talpen, Beecham), has been introduced recently to improve absorption and to reduce these side effects. After oral administration talampicillin is rapidly absorbed and hydrolysed by tissue esterases in the intestinal wall to release into the circulation ampicillin and the ester moiety, mainly 2-hydroxymethyl-benzoic acid. No unchanged talampicillin is detectable in the peripheral blood. It is not approved by the FDA for use in the United States

Bietaserpine is a derivative of a Rauwolfia alkaloid reserpine. It was used as an antihypertensive agent and marketed in the 1960s in France and Italy. Bietaserpine is believed to act by inhibiting VMAT receptors.

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.

Alinidine, a specific bradycardiac agent, which reduces myocardial oxygen consumption and improves exercise tolerance in patients with angina pectoris. In randomized controlled trial alinidine did not enhance myocardial salvage or preservation of left ventricular function of major arrhythmias in the early phase of infarction. The development of this drug was stopped because it was not sufficiently specific for its target.

Glafenine is a non-steroidal anti-inflammatory drug (NSAID). Glafenine was withdrawn due to the risk of anaphylaxis and acute kidney failure.

Pholcodine is an opioid that has been widely used worldwide since 1950 for the treatment of non-productive cough in children and adults. Illicit drug. Additionally Pholcodine is a marker for sensitization to neuromuscular blocking agents (NMBA) and is intended for use as a diagnostic tool in NMBA-induced anaphylaxis.

Bradykinin, a pro-inflammatory mediator is also a neuromediator and regulator of several vascular and renal functions. Bradykinin can act as a vasoactive substance along with histamine in inflammation and swelling as it is a potent vasodilator. In addition, it triggers the release of other mediators such as nitric oxide in inflammatory and cancer tissues. Bradykinin acts via specific cell surface receptors: bradykinin receptor, B1 and B2 that are G-protein coupled receptors of the seven-transmembrane domain family. It was shown that increased plasma levels of bradykinin lead to the angioedema as the common major clinical manifestation. Bradykinin was also studied in heart transplant recipients and in obesity patients, but these studies were terminated or withdrawn for different reasons. Bradykinin is also an important growth factor for many cancers. Bradykinin antagonists showed higher potency than standard anti-cancer drugs, without evident toxicity to the hosts, that is why they have great promise for the development of new anti-cancer drugs.

Oxaflumazine acid disuccinate, a neuroleptic drug, was studied in the treatment of psychotic children in a pedopsychiatric environment.

Isaxonine (N-isopropyl-amino-2-pyrimidine orthophosphate) is able to accelerate nerve regeneration and functional recovery. Isaxonine has specific affinity for peripheral nerves. It acts directly on the neuron or indirectly by stimulating the production of a growth factor remains unknown. It demonstrates activity in the treatment of neuropathies of various etiology. Isaxonine treatment may be associated with hepatotoxicity.
