IODOHIPPURIC ACID I-131 (ortho-Iodohippuric Acid I-131, [I-123]-OIH) is an iodine-containing compound used in pyelography as a radiopaque medium. Iodine-123 labelled ortho-Iodohippuric acid was used in the early 1970's as a kidney imaging agent or tracer that "lights-up" inside your body when scanned, but over the years its use has declined. [I-123]-OIH is primarily extracted by the renal tubules and has excellent pharmacokinetic properties, with a clearance only slightly less than that of p-aminohippuran, but its use has been compromised by the suboptimal imaging characteristics of the 364-keV photon of 131I and the delivery of relatively high radiation doses to kidneys and thyroid in patients with impaired renal function

Clofibrate is a fibric acid derivative used to lower cholesterol and triglyceride (fat-like substances) levels in the blood. This may help prevent medical problems caused by such substances clogging the blood vessels. However, this treatment was discontinued in 2002 due to adverse effects. Clofibrate is an agonist of the PPAR-α receptor in muscle, liver, and other tissues. This agonism ultimately leads to modification in gene expression resulting in increased beta-oxidation, decreased triglyceride secretion, increased HDL, and increased lipoprotein lipase activity. Clofibrate increased the activity of extrahepatic lipoprotein lipase (LL), thereby increasing lipoprotein triglyceride lipolysis, inhibited the synthesis, and increases the clearance of apolipoprotein B, a carrier molecule for VLDL. In addition, clofibrate was investigated as a novel therapy agent in multiple myeloma and it shown the promising results.

Sulfametoxydiazine (INN) or sulfamethoxydiazine (USAN: sulfameter) is a long-acting sulfonamide antibacterial, shows bacteriostatic effects against Gram positive and Gram negative bacteria in vivo. It is used as a leprostatic agent and in the treatment of urinary tract infections. Orally active. Sulfonamides block the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfonamides are competitive inhibitors of bacterial para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid. Sulfameter is a dihydrofolate reductase (DHFR) inhibitor. Mode of resistance is via the alteration of dihydropteroate synthase or alternative pathway for folic acid synthesis.

Methaqualone is a depressant that modulates the activity of the GABA receptors in the brain and nervous system. It promotes relaxation, sleepiness and sometimes a feeling of euphoria. It causes a drop in blood pressure and slows the pulse rate. These properties are the reason why it was initially thought to be a useful sedative and anxiolytic. Common side effects of Methaqualone include dizziness, nausea, vomiting, diarrhea, abdominal cramps, fatigue, itching, rashes, sweating, dry mouth, tingling sensation in arms and legs, seizures and its depressant effects include reduced heart rate and respiration. The drug became banned in many countries and was withdrawn from many markets in the early 1980s.

Attapulgite (magnesium aluminum phyllosilicate) is a clay mineral found in soils common to the Southeastern United States. It is widely used in medicine as an over-the-counter drug for the treatment of diarrhea. Attapulgite acts by physically binding to aacids and toxic substances in the stomach and digestive tract.

Iopanoic acid and ipodate salts have been used for oral cholangiography to visualize the biliary ducts. Ipodate salts have been used for the long-term treatment of Graves' disease and in hyperthyroidism. Ipodate reduced levels of T3 and T4 in the patients. Ipodate also inhibits the conversion of T4 to T3. It is not considered a first-line approach. Ipodate sodium lacks FDA approval for these uses. During investigation of mechanism of action was discovered, that binding of sodium ipodate with nuclear T3 receptors was not a prominent mechanism via which the drug attenuates T3 effects in vivo. Sodium ipodate could enhance T3 effects at the cellular level and that enhancement could not be reflected by routinely monitored serum TSH.

Guanethidine belongs to the general class of medicines called antihypertensives. It was used to treat high blood pressure (hypertension). It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues. It is taken up by norepinephrine transporters. It becomes concentrated in NE transmitter vesicles, replacing NE in these vesicles.

Chloroxylenol is used as a preservative in cooling fluids, cosmetics, topical medications, urinary antiseptics and metal working fluids. Products containing Chloroxylenol are used for cleaning and disinfecting wounds, abrasions and abscesses, for minor cuts and scratches, insect bites, burns, inflammation of the skin. It is also found in hair conditioners, toilet cleaners, deodorants, soaps and paste. New use cases continue to be identified. Chloroxylenol has been shown to be effective at reducing the number of pathogenic bacteria in clinical environments. Chloroxylenol has been reviewed and is permitted for use within the European Union (EU) in cosmetic products and is also permitted for use in a number of topical pharmaceutical products as licensed by the UK Medicines and Health Regulatory Agency. Chloroxylenol could cause mild skin irritation in some individuals, or cause an allergic reaction in others. Developed in Europe in the 1920s and used in the United States since the 1950s, Chloroxylenol is one of the most mature antimicrobial agents

Oxyphenbutazone is a non-steroidal anti-inflammatory drug, cyclooxygenase (prostaglandin synthetase) inhibitors which was marked under brand name tandearil for the treatment rheumatic disorders such as ankylosing spondylitis, osteoarthritis, and rheumatoid arthritis. But this drug was withdrawn from markets due to bone marrow suppression.
