Cephacetrile, a parenteral cephalosporin, is a broad-spectrum first generation cephalosporin antibiotic effective in Gram-positive and Gram-negative bacterial infections. It works by inhibition of bacterial cell wall synthesis. It attains high serum levels and is excreted quickly via the urine. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cephacetrile was used in the treatment of female pelvic inflammatory disease, meningitis and number of other systemic, respiratory and urinary infections.

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 Peptavlon was discontinued, Federal Register determined that product was not discontinued or withdrawn for safety or efficacy reasons.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.

Cyanocobalamin Co 57 is a manufactured form of radiolabeled vitamin B indicated as an adjunct in diagnosing intestinal cyanocobalamin malabsorption syndromes due to lack of intrinsic factor (IF) or other defects in intestinal absorption (e.g., blind loop syndrome and diverticulitis, celiac disease, Crohn's disease, lesions in the small intestine, severe pancreatitis, tropical sprue).

Methylparaben (E number E218) is preservative in the food, cosmetic, and pharmaceutical industries. It is completely absorbed through the skin or after ingestion and and it is hydrolyzed to para-hydroxybenzoic acid, and metabolites are rapidly excreted in the urine. Methylparaben is on the FDA generally regarded as safe list.

Isosorbide is an effective hyperosmotic agent which can be administered orally without gastrointestinal irritation. It is absorbed quantitatively and more than 95% of the administered dose is excreted unchanged in the urine. Oral administration of a 50% solution to rabbits or man results in prompt increases in osmolarity of the serum and profound decreases in intraocular pressure. The drug proves useful in acute primary and secondary glaucomas, and as preoperative medication for various surgical procedures including cataract extraction, retinal detachment, corneal transplant, and glaucoma operations.

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.

Apaflurane (HFC 227) is gaseous halocarbon commonly used as a gaseous fire suppression agent, it is a CFC-free propellant. Apaflurane is used to replace chlorofluorocarbons (CFCs) in refrigerant and aerosol applications, including medical use in metered-dose inhalers.
