Mebhydrolin (INN) or mebhydroline is a histamine H1-receptor antagonist. It is not available in the United States, but it is available in various other countries under the brand names Bexidal and Diazolin. It is used for symptomatic relief of allergic symptoms caused by histamine release, including nasal allergies and allergic dermatosis.

Tinoridine is a non-steroidal anti-inflammatory and analgesic agent. This agent has been proved pharmacologically to show antiedematous and analgesic actions. The mechanism of the anti-inflammatory action of Tinoridine is attributed to its biomembrane stabilizing action particularly on the lysosomes which are related to cell or tissue damage at the time of inflammation through the release of hydrolytic enzymes. Tinoridine may produce gastrointestinal disorders (nausea, loss of appetite, diarrhea, and constipation), vertigo drowsiness, dry mouth and itching.

Moxaverine, a derivative of papaverine, is a phosphodiesterase inhibitor. Moxaverine has been studied in phase III of a clinical trial for the treatment of ocular blood flow in patients with age- related macular degeneration and primary open angle glaucoma. In addition, it has been studied in phase II of the clinical trial for the treatment of ischemia. This compound is prohibited by FEI (International Federation of equine).

Butoxamine is a selective antagonist of the beta2 adrenergic receptor. It was discovered in laboratories of Farbwerke Hoechst. Administration of 25-50 mg subcutaneously or 50-150 mg orally induced mescaline syndrome, disorders of consciousness and a psychotic episode with amnesia. At an oral dose of 5 mg, butoxamine inhibited metabolic changes induced by fasting and administration of catecholamines. Butoxamine was not developed further and is mainly used in biomedical research to study the functional role of beta2 receptors.

Benexate is an active ingredient of benexate.CD or benexate hydrochloride betadex, a beta-cyclodextrin complex. Benexate was approved for the treatment of Gastric Ulcer in Japan. The terapeuthic effect of benexate is associated with promotion of prostaglandin synthesis, inhibition of acid secretion and increase in mucosal blood flow.

Bendazac, (1-benzyl-1H-indazol-3-yl-oxy)-acetic acid, is structurally related to indomethacin. Its lysine salt has been reported to be absorbed better than the parent compound. It is applied topically as bendazac lysine 0.5% (wt/vol) aqueous solution for delaying the progression of cataract. Topical application of bendazac is associated with transient burning sensation. It reduces the secretion of the skin ulcer surface, promotes skin formation and accelerates tissue repair.

Histapyrrodine was investigated as a neuro-sedative drug for the treatment of anxiety and states of aggression.

Clorprenaline is a β2-adrenergic receptor agonist. As a bronchodilator it has been used for the treatment of bronchial asthma, bronchitis and other respiratory diseases. It is a potential new lean meat-boosting feed additive because it can promote animal muscular mass growth and decrease fat accumulation.

Clobutinol is a cough suppressant that is withdrawn from the US and EU markets. Clobutinol was used for the short-term treatment of irritable, non-productive cough (a ‘dry' cough where the patient does not cough up any phlegm or mucus). Medicines containing clobutinol have been available since 1961 and were authorised in a number of Member States. Clobutinol-containing medicines were available in Austria, Belgium, the Czech Republic, Germany, Greece, Finland and France. They include tablets, oral solutions, syrups and solutions for injection, and were available over-the-counter in many Member States. Clobutinol was available as generic and branded medicines, most of which were marketed by Boehringer Ingelheim under the trade name Silomat. Studies in 2004 had indicated that clobutinol has the potential to prolong the QT interval. In 2007, Clobutinol was determined to cause cardiac arrhythmia in some patients.

Tulobuterol is a long-acting beta2-adrenergic receptor agonist. Tulobuterol has almost no effects on blood pressure and heart rate and is highly selective for the tracheal muscle. It is indicated to improve symptoms such as respiratory distress caused by airway obstruction of bronchial asthma, bronchitis, chronic obstructive pulmonary disease (COPD) and emphysema. Serious side effects detected were: tremor, palpitations and serum potassium level decrease.
