It is used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome. It is taken by mouth or by injection into a vein. It begins working within an hour.

Methaqualone is a sedative-hypnotic medication that was widely prescribed during the mid-20th century. It was marketed under various brand names, including Quaalude ( ) and Sopor, typically containing 300 mg of methaqualone per tablet. A combination drug known as Mandrax was sold primarily in Europe, containing 250 mg of methaqualone and 20 mg of diphenhydramine in a single tablet.

Dabigatran, sold under the brand name Pradaxa among others, is an anticoagulant used to treat and prevent blood clots and to prevent stroke in people with atrial fibrillation. It is commonly used to prevent blood clots following hip or knee replacement and in those with a history of prior clots. and is used as an alternative to warfarin; it does not require monitoring by blood tests. In a meta-analysis of seven different studies, there was no benefit of dabigatran over warfarin in preventing ischemic stroke; however, dabigatran was associated with a lower hazard for intracranial bleeding compa

DAPI (pronounced 'DAPPY', /ˈdæpiː/), or 4′,6-diamidino-2-phenylindole, is a fluorescent stain that binds strongly to adenine–thymine-rich regions in DNA. It is used extensively in fluorescence microscopy. As DAPI can pass through an intact cell membrane, it can be used to stain both live and fixed cells, though it passes through the membrane less efficiently in live cells and therefore provides a marker for membrane viability.

Pentamidine is an antimicrobial medication used to treat African trypanosomiasis, leishmaniasis, Balamuthia infections, babesiosis, and to prevent and treat pneumocystis pneumonia (PCP) in people with poor immune function. In African trypanosomiasis it is used for early disease before central nervous system involvement, as a second line option to suramin. It is an option for both visceral leishmaniasis and cutaneous leishmaniasis. Pentamidine can be given by injection into a vein or muscle or by inhalation.

Amitraz (development code BTS27419) is a non-systemic acaricide and insecticide and has also been described as a scabicide. It was first synthesized by the Boots Co. in England in 1969. Amitraz has been found to have an insect repellent effect, works as an insecticide and also as a pesticide synergist. Its effectiveness is traced back on alpha-adrenergic agonist activity, interaction with octopamine receptors of the central nervous system and inhibition of monoamine oxidases and prostaglandin synthesis. Therefore, it leads to overexcitation and consequently paralysis and death in insects. Beca

Ectoine (3,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) is a natural compound found in several species of bacteria. It is a compatible solute which serves as a protective substance by acting as an osmolyte and thus helps organisms survive extreme osmotic stress. Furthermore it was shown to protect DNA against ionizing and ultraviolet radiation serving as a radical scavenger. Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism Ectothiorhodospira halochloris, b

Diminazene (INN; also known as diminazen) is an anti-infective medication for animals that is sold under a variety of brand names. It is effective against certain protozoa such as Babesia, Trypanosoma, and Cytauxzoon. The drug may also be effective against certain bacteria including Brucella and Streptococcus.

Phenamidine is an antiprotozoal drug of the amidine class used in veterinary medicine. It is used to treat Babesia infection (babesiosis) dogs, horses, and cattle. Because the drug causes frequent allergic reactions, it is usually combined with an antihistamine.

Ebrotidine is an H2 receptor antagonist with gastroprotective activity against ethanol-, aspirin- or stress-induced gastric mucosal damage. The antisecretory properties of ebrotidine are similar to those of ranitidine, and approximately 10-fold greater than those of cimetidine. Ebrotidine has anti-Helicobacter pylori activity via inhibition of the urease enzyme and the proteolytic and mucolytic activities of the bacterium. However, its activity is synergistic with a number of antibacterial agents. Ebrotidine counteracts the inhibitory effects of H. pylori lipopolysaccharides. Ebrotidine was wi

Tribendimidine is a broad-spectrum anthelmintic agent developed in China, at the National Institute of Parasitic Diseases in Shanghai. It is a derivative of amidantel.

Dimaprit is a histamine analog working as a selective H2 histamine receptor agonist.

A-232 is an organophosphate nerve agent. It was developed in the Soviet Union under the FOLIANT program and is one of the group of compounds referred to as Novichok agents that were revealed by Vil Mirzayanov. A-232 is reportedly slightly less potent as a nerve agent compared to some of the other compounds in the series such as A-230 and A-234, having similar potency to the older nerve agent VR. However it proved to be the most versatile agent as it was chemically stable and remained a volatile liquid over a wide temperature range, making it able to be used in standard chemical munitions witho

Formetanate is an insecticide and acaricide. It is used on alfalfa grown for seed and on some fruits, including citrus, pome, and stone fruits.

Taribavirin (rINN; also known as viramidine, codenamed ICN 3142) is an antiviral drug in Phase III human trials, but not yet approved for pharmaceutical use. It is a prodrug of ribavirin, active against a number of DNA and RNA viruses. Taribavirin has better liver-targeting than ribavirin, and has a shorter life in the body due to less penetration and storage in red blood cells. It is expected eventually to be the drug of choice for viral hepatitis syndromes in which ribavirin is active. These include hepatitis C and perhaps also hepatitis B and yellow fever.

Dibrompropamidine is an antiseptic and disinfectant. As dibrompropamidine isethionate, it is used in eyedrops and ointment for the treatment of minor eye and eyelid infections in adults and children. In the UK, such preparations are sold under the brand names Brolene (Aventis Pharma), Golden Eye (Typharm Ltd), and Brulidine (Manx Healthcare).

Phenacaine, also known as holocaine, is a local anesthetic. It is approved for ophthalmic use.

Xylamidine is a drug which acts as an antagonist of the serotonin 5-HT2A and 5-HT2C receptors, and to a lesser extent of the serotonin 5-HT1A receptor. The drug does not cross the blood–brain barrier and hence is peripherally selective, which makes it useful for blocking peripheral serotonergic responses like cardiovascular and gastrointestinal effects, without producing the central effects of 5-HT2A receptor blockade such as sedation, or interfering with the central actions of 5-HT2A receptor agonists.

Sibrafiban (Ro 48–3657, proposed brand name Xubix) is the double prodrug of Ro-44-3888, which is a platelet aggregation inhibitor. It was being developed for secondary prevention of arterial thrombosis following unstable angina pectoris and acute myocardial infarction (MI). On August 6, 1999, Hoffmann-La Roche announced that the preliminary results from Phase III clinical trials had not shown that sibrafiban was better than aspirin in preventing recurrent ischemic events in patients with acute coronary syndrome. The development of sibrafiban was terminated.
