Neridronic acid (6-amino-1-idroxyesilidene-1,1-bisphosphonate) is a nitrogen-containing bisphosphonate licensed in Italy for the treatment of osteogenesis imperfecta and Paget’s disease of bone. The pharmacodynamic profile is similar to that of other nitrogen-containing bisphosphonates and is characterized by its high affinity for bone tissue particularly at sites undergoing a process of remodeling. In growing children affected by osteogenesis imperfect, neridronic acid rapidly increases bone mineral density as measured by dual X-ray absorptiometry and this is associated with a significant decrease in fracture cumulative number. Similar results have been obtained also in newborns (<12-month-old) and in adult patients. In Paget’s disease of bone, 200 mg intravenous neridronic acid is associated with a 65% rate of full remission and a biochemical response (decrease of > 75% of bone turnover markers) in 95% of the patients. Neridronic acid treatment has been reported to be effective also in other skeletal diseases such as osteoporosis, algodystrophy, hypercalcemia of malignancy and bone metastasis. Neridronic acid has been developed only for parenteral use, and it is the only one used as the intramuscular injection. This avoids all the limitations of oral bisphosphonates and may be offered for a home treatment with simple nursing assistants

Bucloxic acid, a nonsteroidal anti-inflammatory agent, which was studied to treat the chronic glomerular nephropathy.

Tolonidine, 2(2-chloro-p-toluidino)-2-imidazoline-nitrate, is a substance chemically related to clonidine. In the anesthetized dog, tolonidine administered i.v. decreased the amplitude of ventricular contractions, reduced aortic blood flow and increased peripheral vascular resistances. In the bivagotomized pithed rat, tolonidine induced a long-lasting increase in blood pressure with no secondary hypotension, thus suggesting peripheral sympathomimetic properties, however, contractions of seminal vesicles in vitro were not obtained. The product proved to have no peripheral sympatholytic or parasympatholytic properties.

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.

Butriptyline is a tricyclic antidepressant used in patients with depression associated with anxiety. The drug is supposed to be withdrawn from the market as the last publication about its clinical use is dated by 1988.

Chloropyramine is an antagonist of H1 histamine receptors. It is indicated for the treatment of various forms of allergic reactions. Chloropyramine is a drug capable of (1) inhibiting the biochemical function of VEGFR-3 and FAK, (2) inhibiting proliferation of a diverse set of cancer cell types in vitro, and (3) reducing tumor growth in vivo.

Fazadinium (used as a bromide salt) is a muscle relaxant, which was applied in anesthesia under the name Fazadon. The current marketing status is unknown and the drug is supposed to be discontinued.

Xylamidine is a peripherally-restricted antagonist of 5HT2A and 5HT1A receptor. It is used to study the role of the serotonin receptors in the regulation of food intake, cardiovascular function, and regulation of body temperature.

Demexiptiline (Tinoran, Deparon) is a tricyclic antidepressant, noradrenergic drug. It is a norepinephrine reuptake inhibitor. Deparon was used in France for the treatment of depression.
