Iodoxamic acid (previously sold under the brand name Cholovue) is an organoiodine compound that was used as a contrast medium. It is intravenous cholecystocholangiographic agent. It features both a high iodine content as well as several hydrophilic groups.

Iodamide is an ionic monomeric iodinated radiographic contrast medium. It was used in many procedures and may be given intravenously or by other routes, for example by instillation into the bladder or uterus; it has also been used for computed tomography. It is usually given as a 24 to 65% solution of the meglumine salt, or as a mixture of the sodium and meglumine salts; solutions of the sodium salt have also been used. Iodamide is no longer marketed in the US.

Metrizamide is a glucosamine derivative of metrazoic acid, used as a contrast medium for myelography. Metrizamide is no longer marketed in the US.

Meglumine (N-methyl-D-glucamine) is a poorly metabolized derivative of sorbitol that has regulatory acceptance as a benign excipient for drug formulation to increase aqueous solubility of lipophilic drugs and improve their absorption. In conjugated form meglumine is used as a contrast agent.

Pentagastrin (trade name Peptavlon) is a cholecystokinin type B (CCK(B)) receptor agonist, which was indicated as a diagnostic aid for evaluation of gastric acid secretory function. It was effective in testing for an acidity (achlorhydria) in patients with suspected pernicious anemia, atrophic gastritis, or gastric carcinoma. It was effective in determining the reduction in acid output after operations for peptic ulcer, such as vagotomy or gastric resection. Pentagastrin was also indicated as a diagnostic aid in testing for gastric hypersecretion in patients with suspected duodenal ulcer or postoperative stomal ulcer, and for the diagnosis of Zollinger-Ellison tumor. Peptavlon was discontinued, Federal Register determined that product was not discontinued or withdrawn for safety or efficacy reasons. In addition was shown, that Pentagastrin may release adrenocorticotropin (ACTH) and cortisol through direct pharmacological action, perhaps enhanced on first exposure by psychologically mediated novelty effects. Novelty, per se, is not likely the primary mediator of the hypothalamic-pituitary-adrenal (HPA) response. This model may be useful for further study of cognitive-emotional modulators of HPA axis activity.

CHLORMERODRIN HG-197 is a radiolabelled form of chlormerodrin, an organomercury compound that was previously used as a diuretic. Its radiolabelled form was used as diagnostics in brain scans.

Iocetamic acid is a medical diagnostic aid. It is a contrast agent used to enhance structures or fluids during X-ray imaging.

Metrizoic acid is a diagnostic radiopaque that usually occurs as the sodium salt. The mechanism of action of metrizoic acid is as a X-Ray Contrast Activity.

Stearyl Alcohol is long chain fatty alcohol. Stearyl alcohol is prepared from stearic acid or some fats by the process of catalytic hydrogenation. It has low toxicity. Stearyl Alcohol is used in surface-active agents, lubricants, emulsions, resins, and USP ointments and as a substitute for cetyl alcohol and antifoaming agents. Stearyl Alcohol (synthetic) has been approved as a direct food additive (DFA) ingredient, to be used under the same manufacturing practices as the natrual alcohol product. It also has indirect food additive (IFA) status for use in food containers. Stearyl Alcohol is also used as an ingredient in over-the-counter (OTC) drugs of the miscellaneous external drug product category. It is considered to be safe at a concentration of 8 percent or less. Stearyl Alcohol is used in cosmetics as an emollient, stabilizer, antifoaming agent, emulsifier, and carrier. It is used as a water in oil (w/o) emulsifier to produce firm cosmetic products at ordinary temperatures.

Tyropanic acid and its salt sodium tyropanoate are radiocontrast agents used in cholecystography (X-ray diagnosis of gallstones). Tyropanic acid is sold under the trade names Bilopaque, Lumopaque, Tyropaque, and Bilopac. The molecule contains three heavy iodine atoms which obstruct X-rays in the same way as the calcium in bones to produce a visible image. After injection it is rapidly excreted into the bile.
