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

Homofenazine (or Pasaden) is a psycho sedative drug, developed in Germany.

Iotroxic acid (INN), also known as meglumine iotroxate (BAN) (Biliscopin) for infusion is indicated for radiological examination of the hepatic and biliary ducts and gallbladder when examination by oral technique is unsuccessful or inappropriate. Following intravenous administration Biliscopin is rapidly excreted, mainly by the liver into the bile. Visualisation of the hepatic and common bile ducts and the gallbladder can, therefore, be achieved. Visualisation of the biliary ducts is usually possible 30-60 minutes after completion of administration. In vitro meglumine iotroxate binds to plasma proteins to the extent of 60-90% depending on concentration. In animals it crosses the placental barrier. This agent is the single intravenous cholangiographic agent, which is currently available in Australia.

BQ-788, a selective endothelin (ET) B-receptor antagonist, was developed by Banyu. This compound is widely used to demonstrate the role of ET-1 and ET(B) receptor subtypes in physiological and/or pathophysiological conditions. BQ-788 was studied against hypertension. However, this study was discontinued. Besides, was shown that BQ788 could protect against brain edema by inhibiting vascular endothelial growth factor-A-mediated decrease in claudin-5. The intralesional applications of BQ788 were well tolerated and showed signs of directly and indirectly reducing the viability of melanoma cells.

Ketanserin is a selective 5HT2A receptor antagonist which was initially developed as an anti-hypertensive medicine. However, now the drug is available as a topical gel formulation for the treatment of wounds, burns, ulcers and anal fissure (Sufrexal brand name). The drug action is explained by its ability to accelerate epithelialization.

Oxeladin citrate is a cough suppressant, is a highly potent and effective drug used to treat all types of cough of various etiologies. Withdrawn from the Canadian, US, and UK markets in 1976 due to carcinogenicity. Oxeladine is a component of antitussive drug, Altussan, approved in Philippines.

Capobenic acid is an antiarrythmetic agent, vasodilator, antianginal used for the treatment of cardiac infarction.

Bamipine (trade name Soventol) is a sedating antihistamine with pronounced sedative effects. Bamipine is a pharmaceutical drug acting as an H1 antihistamine with anticholinergic properties. It is used as an antipruritic ointment. Bamipine hydrochloride has been given by mouth. Bamipine, bamipine lactate, and bamipine salicylate have all been applied topically.

Mifamurtide (liposomal muramyl tripeptide phosphatidylethanolamine; trade name Mepact) is an immunomodulator with antitumor effects that appear to be mediated via activation of monocytes and macrophages. After intravenous administration, mifamurtide is selectively phagocytosed by monocytes and macrophages. Cytosolic Mifamurtide specifically interacts with nucleotide-binding oligomerization domain 2 (NOD2) receptor that induces nuclear factor (NF)-kB activation and is implicated in innate immune defense. Activation of monocyte-mediated tumoricidal function was observed following in vivo treatment with mifamurtide in phase I/II clinical trials. Intravenous administration of mifamurtide inhibited tumor growth and increased survival in rodent models of lung and liver metastasis. In a large, randomized, open-label, multicenter, phase III trial, the addition of adjuvant (postoperative) mifamurtide to three- or four-drug combination chemotherapy (doxorubicin, cisplatin, and high-dose methotrexate with, or without, ifosfamide) was associated with a statistically significant improvement in overall survival in patients with newly diagnosed, high-grade, non-metastatic, resectable osteosarcoma. The pattern of outcome was generally similar in a small cohort of patients with metastatic disease who were enrolled in this trial. Mifamurtide is generally well tolerated; adverse events attributed to administration of the drug include chills, fever, headache, nausea, and myalgias. In the EU, mifamurtide is indicated in children, adolescents, and young adults for the treatment of high-grade, resectable, non-metastatic osteosarcoma after macroscopically complete surgical resection; it is administered by intravenous infusion in conjunction with postoperative multiagent chemotherapy. In the US, mifamurtide is currently an investigational agent that holds orphan drug status for the treatment of osteosarcoma.

Flupirtine is a triaminopyridine derivative having a chemical structure - 2-amino-3-ethoxy-carbonylamino-6-4-fluoro-benzylamino-pyridine. The basic molecule used for synthesis of flupirtine was 2, 6-dichoro 3-nitropyridine. It was first synthesized in 1980s in Germany and was marketed by Degussa Pharma. Flupirtine is a centrally acting, non-opioid analgesic that is available in a number of European countries for the treatment of a variety of pain states. The therapeutic benefits seen with flupirtine relate to its unique pharmacological properties. Flupirtine displays indirect NDMA receptor antagonism via activation of potassium channels and is the first representative of a pharmacological class denoted the 'selective neuronal potassium channel openers'. The generation of the M-current is facilitated by flupirtine via the opening of neuronal Kv7 potassium channels. The opening of these channels inhibits exaggerated neuronal action potential generation and controls neuronal excitability. Neuronal hyperexcitability is a physiological component of many pain states such as chronic pain, migraine and neurogenic pain.
