Chloramphenicol is a broad-spectrum antibiotic that was first isolated from Streptomyces venezuelae in 1947. The drug was subsequently chemically synthesized. It has both a bacteriostatic and bactericidal effect; in the usual therapeutic concentrations it is bacteriostatic. Chloramphenicol is used for the treatment of serious gram-negative, gram-positive, and anaerobic infections. It is especially useful in the treatment of meningitis, typhoid fever, and cystic fibrosis. It should be reserved for infections for which other drugs are ineffective or contraindicated. Chloramphenicol, a small inhibitor of bacterial protein synthesis, is active against a variety of bacteria and readily enters the CSF. It has been used extensively in the last decades for the treatment of bacterial meningitis. In industrialized countries, chloramphenicol is restricted mostly to topical uses because of the risk of induction of aplastic anemia. However, it remains a valuable reserve antibiotic for patients with allergy to β-lactam antibiotics or with CNS infections caused by multiresistant pathogens.

The therapeutic use of radioactive colloidal gold Gold Au-198 (Au198) was first described by Sheppard et al., who reported on intravenous use in 1947. Its possibilities for the treatment of various malignant processes have been explored in great variation. Gold Au-198 is an antineoplastic, diagnostic aid (liver imaging) and radioactive agent. Thus, intracavitary instillation of colloidal radioactive gold Au-198 was used for treatment of patients with multiple papillomata of the bladder. Approximately 300 mc. of gold was instilled into the bladder for four to six hours to deliver a dose of about 4,000 to 5,000 r to the bladder epithelium. The treatment had no harmful side-effects locally or on the general condition of the patient. It was also used to estimate the hepatic blood flow in children with active or progressive chronic hepatitis. Gold Au-198 was used in the combination therapy of rectal cancer.

Diethylcarbamazine is used in humans, dogs and cats for the treatment of parasitic infections, including pulmonary eosinophilia, loiasis, and lymphatic filariasis. The exact mechanism of its action is unknown, however some studies showed the involvment of inducible nitric-oxide synthase and the cyclooxygenase pathway. Although there is no information on whether the drug is marketed in the USA and Europe, it is currently used in India.

Cyclamic acid (Cyclamate) is banned in the United States but it is used in many other Western countries without safety concerns. Cyclamate interacts with the sweet taste receptor subunit T1R3 transmembrane domain. Initially it was recommended for use in treatment of obese patients and by individuals with diabetes but in August 27, 1970 FDA concluded that there was no substantial evidence of effectiveness of cyclamate compounds at any level for treatment of obese patients and individuals with diabetes and therefore prohibited continued sale of cyclamate containing products with drug labeling. cyclamate is the putative carcinogenic agent. Cyclamate was tested in the Maximal Electroshock Seizure model (mice, ip), showing moderate anticonvulsant activity.

Cortisone is a hormone that is FDA approved for the treatment of primary and secondary adrenocortical deficiency, rheumatic disorders, psoriasis, exfoliative dermatitis, bronchial asthma, allergic conjunctivitis, hemolytic anemia, enteritis, tuberculosis, trichnosis. Cortisone acetate binds to the cytosolic glucocorticoid receptor. After binding the receptor, the newly formed receptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (GRE) in the promoter region of the target genes. The DNA bound receptor then interacts with basic transcription factors, causing the increase in expression of specific target genes. Common adverse reactions include convulsions, increased intracranial pressure with papilledema, vertigo, headache, psychic disturbances, hirsuitism, glaucoma, exophthalmos. Aminoglutethimide may lead to a loss of corticosteroid-induced adrenal suppression. Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Cortisone is a natural steroid hormone. Its sulfate analog has been detected in in umbilical vein blood fetus plasma between 19 and 32 weeks of gestation with a significant increase at 29-30 weeks and in amniotic fluid. Base on the experiments with rats it was suggested that cortisone sulfate in mammals could be hydrolyzed enzymatically liberating sulfate ions from cortisone. Cortisone sulfate has been proposed for use as one of the glycosaminoglycan compound materials in a cartilage prosthesis and biological nasal bridge implant manufacture as well as auxiliary agent in powder aerosol composition for use in baby powder, dry shampoo, water-eczema remedy and antiperspirant.

Thiphenamil, an antispasmodic drug with a local anesthetic activity, inhibits contraction. The clinical trials have shown that thiphenamil could suppress upper urinary tract contractility, and was suggested to use the drug for renal colic and stone management. In addition, this drug was studied for the treatment of detrusor incontinence in patients with detrusor instability. The results showed, that the drug caused a significant decrease in problems due to loss of urine when the patient was taking the drug compared to the placebo.

Amodiaquine is a medication used to treat malaria, including Plasmodium falciparum malaria when uncomplicated. The mechanism of plasmodicidal action of amodiaquine is not completely certain. Like other quinoline derivatives, it is thought to inhibit heme polymerase activity. This results in accumulation of free heme, which is toxic to the parasites. The drug binds the free heme preventing the parasite from converting it to a form less toxic. This drug-heme complex is toxic and disrupts membrane function. The side effects of amodiaquine are generally minor to moderate and are similar to those of chloroquine. Rarely liver problems or low blood cell levels may occur. When taken in excess headaches, trouble seeing, seizures, and cardiac arrest may occur. After oral administration amodiaquine hydrochloride is rapidly absorbed,and undergoes rapid and extensive metabolism to desethylamodiaquine which concentrates in red blood cells. It is likely that desethylamodiaquine, not amodiaquine, is responsible for most of the observed antimalarial activity, and that the toxic effects of amodiaquine after oral administration may in part be due to desethylamodiaquine.
