Monostearyl fumarate (sodium stearyl fumarate) is a lubricant for use in tablet formulation, it can be used as a taste-masking agent in orally disintegrating tablets. It is a conditioning and stabilizing agent.

Naftidrofuryl (INN), also known as nafronyl or as the oxalate salt naftidrofuryl oxalate or nafronyl oxalate, is a vasodilator used in the management of peripheral and cerebral vascular disorders. The drug act as a selective antagonist of 5-HT2 receptors. Naftidrofuryl is marketed under a variety of trade names, including Artocoron, Azunaftil, Di-Actane, Dusodril, Enelbin, Frilix, Gevatran, Iridus, Iridux, Luctor, Nafti, Naftoling, Naftodril, Nafoxal, Praxilene, Sodipryl retard, and Vascuprax. Praxilene belongs to a group of medicines known as ‘metabolic activators’. These are used to treat different types of blood circulation problems. Praxilene allows the body to make better use of the oxygen in your blood. Praxilene is used to treat the following symptoms: cramp-like pains; cramps in legs at night; severe pain in r legs when people are resting (rest pain); pale or blue fingers or toes which get worse when it is cold; numbness, tingling or burning feelings in the fingers or toes (Raynaud’s syndrome or acrocyanosis); open sores on the legs or feet (trophic ulcers); poor circulation caused by diabetes (diabetic arteriopathy).

Ormeloxifene (also known as centchroman) is a selective estrogen receptor modulator. It is a once-a-week non-steroidal oral contraceptive agent marketed in India and other countries under the brand names Novex-DS, Centron, and Sevista. Ormeloxifene has been investigated in the management of benign breast diseases such as mastalgia. The l-isomer, levormeloxifene, which has oestrogenic effects, has been investigated in the management of postmenopausal osteoporosis, but development appears to have been discontinued because of adverse effects. Recent studies have shown Ormeloxifene`s potent anti-cancer activities in breast, head and neck, and chronic myeloid leukemia cells. Several in vivo and clinical studies have reported that ormeloxifene possesses an excellent therapeutic index and has been well-tolerated, without any haematological, biochemical or histopathological toxicity, even with chronic administration. In India, ormeloxifene has been available as birth control since the early 1990s, and it is currently marketed there under the trade name Saheli. Ormeloxifene has also been licensed under the trade names Centron and Sevista. Ormeloxifene acts on oestrogen receptors. It has a weak estrogenic and potent antiestrogenic actions. It is expected to exert a contraceptive effect and normalise the bleeding from uterine cavity by regularising the expression of oestrogen receptors on the endometrium. As a contraceptive, it prevents proliferation and decidualisation of the endometrium, enhances blastocyst formation and slightly increases embryo transport through the oviducts.

Velnacrine (9-amino-1,2,3,4-tetrahydroacridin-1-ol) is an inhibitor of acetylcholinesterase. It was studied for the treatment of Alzheimer's disease however development was discontinued. There has been no research into the use of velnacrine as a cognitive enhancer in the treatment of Alzheimer's disease since 1994. The FDA peripheral and CNS drug advisory board voted unanimously against recommending approval. This review shows the toxic nature of velnacrine, and provides no evidence of efficacy.

Zamifenacin, also known as UK-76654, a selective muscarinic M3 receptor antagonist, was studied in patients with irritable bowel syndrome (IBS). This drug participated in clinical trials for the IBS phase III in the USA and phase II in the UK, but these studies were discontinued.

Zanapezil (TAK-147) is a selective reversible acetylcholine (ACh) esterase inhibitor that was designed as a drug for Alzheimer's disease (AD) treatment. The development of the drug was discontinued due to a lack of a dose-dependent effect in the trials.

Urapidil is an anti-hypertensive agent approved in Europe for the treatment of the corresponding disease. The drug acts by activating 5HT1a receptor and inhibiting alpha1-adrenergic receptors.

Nizofenone (Ekonal, Midafenone) is a neuroprotective drug which protects neurons from death following cerebral anoxia (interruption of oxygen supply to the brain). It might thus be useful in the treatment of acute neurological conditions such as stroke. Nizofenone ameliorates various pathophysiologic events during ischemia, such as ATP depletion, lactate accumulation, glutamate release, free fatty acid liberation, edema, and neuronal degeneration; in particular, ischemia-induced excessive glutamate release has been completely blocked by this drug. This drug has also radical-scavenging action, comparable to vitamin E, and inhibits oxygen radical-induced lipid peroxidation. The potent cerebroprotective effect of nizofenone has been demonstrated in various experimental models of cerebral hypoxia, ischemia (focal and global), ischemia-reperfusion, and infarction. The clinical efficacy of nizofenone has been proved by pioneering double-blind studies in acute subarachnoid hemorrhage patients. Nizofenone is clinically used for preventing the delayed ischemic neurologic deficits due to late vasospasm following subarachnoid hemorrhage.
