Tasosartan is a long-acting angiotensin II (AngII) receptor blocker. Tasosartan is infrequently in the treatment of hypertension and heart failure. The manufacturer withdrew it from FDA review after phase III clinical trials showed elevated transaminases. Tasosartan blocks the renin-angiotensin-aldosterone system (RAAS) at the level of the AT1 receptor that mediates most, if not all, of the important actions of Ang II. Tasosartan binds reversibly to the AT1 receptors in vascular smooth muscle and the adrenal gland. As angiotensin II is a vasoconstrictor, which also stimulates the synthesis and release of aldosterone, blockage of its effects results in decreases in systemic vascular resistance.

Poldine is an antimuscarinic drug, containing quaternary nitrogen. It is a selective inhibitor of gastric secretion. Administration of poldine leads to a 50% reduction of the volume and acid output of gastric juice without troublesome side-effects. Poldine was used for the treatment of gastric and duodenal ulcer under tradename "Nacton".

Gestonorone is a progesterone analogue indicated for the treatment of benign prostatic hyperplasia and endometrial cancer. The drug is approved in many countries and used under the names Primostat and Depostat.

Diiodohydroxypropane was once used as an antiseptic and disinfectant. Diiodohydroxypropane was investigated in the therapy of gingival bacteroiditis.

Sulfadicramide, a sulfonamide with anti-anti-infective properties, it was applied as a 15% ointment for superficial infections of the eye.

Proglumetacin (usually as the maleate salt, trade names Afloxan, Protaxon and Proxil) is a non-steroidal anti-inflammatory drug. Proglumetacin is indicated for the pain and inflammation associated with musculoskeletal and joint disorders. The action of proglumetacin maleate is qualitatively the same as that of indomethacin in vivo; that is, it inhibits cyclo-oxygenase in inflammatory sites.

Temoporfin is a photosensitizer (based on chlorin) used in photodynamic therapy for the treatment of squamous cell carcinoma of the head and neck. It is marketed in the European Union under the brand name Foscan. It is used in patients in whom other treatments have stopped working, and who are not suitable for radiotherapy (treatment with radiation), surgery or systemic chemotherapy (medicines used to treat cancer; ‘systemic’ means that they are given as treatments throughout the body). When Foscan is injected, temoporfin is distributed within the body, including within the tumour. When it is illuminated with laser light of a specific wavelength, temoporfin is activated and reacts with oxygen in the cells to create a highly reactive and toxic type of oxygen. This kills the cells by reacting with and destroying their components, such as their proteins and DNA. By restricting the illumination to the tumour, cell damage is limited to the tumour cells, leaving other areas of the body unaffected. The U.S. Food and Drug Administration (FDA) declined to approve Foscan in 2000. The EU approved its use in June 2001.

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.

Bromperidol (marketed as Bromidol, Bromodol) is a butyrophenone derivative. It is a potent and long-acting neuroleptic, used as an antipsychotic in the treatment of schizophrenia. It was discovered at Janssen Pharmaceutica in 1966. Bromperidol is a bromine analog of Haloperidol hydrochloride (sc-203593) which functions as a D2DR (dopamine D2 receptor) antagonist. Studies suggest that cytochrome CYP3A4 catalyzes the dehydration of Bromperidol and N-dealkylation of Bromperidol. In addition, CYP3A4 can oxidize N-dealkylated Bromperidol back into Bromperidol. Alternately, Bromperidol antagonizes the Neuroendocrine DA receptors which regulate hypothalamic LH-RH release.

Ciclonium bromide is an antimuscarinic agent that acts by action by directly relaxing the smooth muscles. It is not approved in the USA, but available was marketed in other countries for functional or organic disorders associated with anxiety and emotional tension e.g. gastric and duodenal ulcers, gastritis, hypersecretion and gastric discomfort, spastic constipation, bile duct dyskinesia, renal colic, and dysmenorrhoea.
