Tiemonium (often used in a form of iodide or methylsulphate salt) is a muscarinic acetylcholine receptor antagonist, which is available in Asia (mainly Bangladesh) for the alleviation of muscle spasms of the intestine, biliary system, uterus and urinary bladder in gastrointestinal, biliary, urinary and gynecological diseases.

Bibenzonium is an antitussive agent. Bibenzonium bromide is a cough suppressant which is stated to have a central action.

CHLORAL HYDRATE ANTIPYRINE is a 1:1 mixture of antipyrine with chloral hydrate. It was used as a hypnotic drug known as HYPNAL in the late 19th century.

Oxitropium bromide (trade names Oxivent, Tersigan) is a bronchodilator indicated for asthma and chronic obstructive pulmonary disease. Oxitropium’s bronchodilation effect is similar to that of ipratropium bromide, but oxitropium is longer-lasting. The usual dose is 200 ug, 2–3 times daily. It blocks the muscarinic cholinergic receptors which mediate smooth muscle contraction in the airways. The manufacturer claims that regular use of oxitropium (200μg twice or three times daily) reduces the incidence of symptoms, including the need for night-time bronchodilators, and improves lung function in some patients; it is not intended for immediate symptom relief. Although widely used for many years (alone or in combination with short-acting beta agonists) for both maintenance treatment of stable disease and exacerbation of airway obstruction, Boehringer Ingelheim announced the discontinuation of Oxivent formulations at May 2004.

Josamycin is a macrolide antibiotic produced by Streptomyces narbonensis var. josamyceticus. Macrolides are inhibitors of protein synthesis. They impair the elongation cycle of the peptidyl chain by specifically binding to the 50S subunit of the ribosome. Josamycin has antimicrobial activity against a wide spectrum of pathogens. It is similar to erythromycin, but does not induce macrolide resistance in staphylococci and appears to have a lower incidence of gastrointestinal side effects. Josamycin is under investigation in US.

Stibogluconic acid (Sodium stibogluconate) is the pentavalent antimonial compound used to treat leishmaniasis and is only available for administration by injection. Sodium stibogluconate is sold in the UK as Pentostam (manufactured by GlaxoSmithKline). Sodium stibogluconate was granted orphan drug designation for the treatment of cutaneous leishmaniasis by the US FDA in January 2007. It is available in the United States only through the Centers for Disease Control. Sodium stibogluconate is indicated for the treatment of various types of a protozoal infection called leishmaniasis, which may result from sandfly bites in tropical and temperate parts of the world. It is also investigated for use/treatment in cancer. The mode of action of sodium stibogluconate is not clearly understood. In vitro exposure of amastigotes to 500 mg pentavalent antimony/ml results in a greater than 50% decrease in parasite DNA, RNA protein and purine nucleoside triphosphate levels. It has been postulated that the reduction in ATP (adenosine triphosphate) and GTP (guanosine triphosphate) synthesis contributes to decreased macromolecular synthesis. Sodium stibogluconate was shown to specifically inhibit type I DNA topoisomerase from Leishmania donovani through the inhibition of the unwinding and cleavage of the supercoiled plasmid pBR322, and to stabilize topoisomerase and DNA covalent complexes but not calf-thymus topoisomerase I and Escherichia coli DNA gyrase. Sodium stibogluconate is also a potent inhibitor of PTPases Src homology PTPase1 (SHP-1), SHP-2, and PTP1B but not the dual-specificity phosphatase mitogen-activated protein kinase phosphatase 1. Sodium stibogluconate combined with IFN-alpha-2b (IFN-α) inhibited solid tumor cell line growth in vitro, in vivo it was well tolerated and augmented cellular immune parameters.

Buformin (1-butylbiguanide) is an oral antidiabetic drug of the biguanide class. AMPK activator. AMPK is a potential therapeutic target in the prevention and the treatment of type 2 diabetes and insulin resistance. Major classes of antidiabetic drugs have been reported to activate AMPK. Buformin exerts its anti-tumorigenic activity via activation of AMPK and inhibition of the mTOR signaling pathways in endometrial cancer cells. Toxicity: guinea pig LD50 subcutaneous 18 mg/kg; mouse LD50 intraperitoneal 140 mg/kg and 300 mg/kg oral. Buformin was withdrawn from the market in many countries due to an elevated risk of causing lactic acidosis.

Antimonic acid is an inorganic acid formed by antimony. As an ion-exchange material crystalline antimonic acid may be used for the regeneration of heteropolyacid catalysts. In addition, as a proton conductor, it may be used for gas sensing.

Temocapril is a prodrug-type angiotensin-I converting enzyme (ACE) inhibitor not approved for use in the United States but is approved in Japan and South Korea. Temocapril can also be used in hemodialysis patients without risk of serious accumulation.

Clevudine (also known as L-FMAU) is a nucleos(t)ide reverse transcriptase inhibitor, which inhibits the DNA synthesis activity of the hepatitis B virus polymerase. The drug was approved in Korea and Philippines and is being marketed under the names Levovir and Revovir. The drug is indicated in patients with chronic hepatitis B virus infection. Upon administration, clevudine is metabolized to the active metabolite, clevudine triphosphate, which is responsible for the inhibition of viral polymerase.
