Oxymetholone (17beta-hydroxy-2-[hydroxymethylene]-17-methyl-5alpha-androstan-3-one) is a 17alpha-alkylated anabolic-androgenic steroid and a synthetic derivative of testosterone. It has been approved by the US Food and Drug Administration for the treatment of anemias caused by deficient red cell production. Acquired aplastic anemia, congenital aplastic anemia, myelofibrosis and the hypoplastic anemias due to the administration of myelotoxic drugs often respond. Drug interactions exist with cimetidine, paroxetine, and haloperidol, but are not expected with indinavir, ritonavir, clarithromycin, or itraconazole.

Benzthiazide (trade names Aquatag, Dihydrex, Diucen, Edemax, Exna, Foven and others) is a thiazide diuretic used in the treatment of high blood pressure and edema. It is no longer available in the United States. As a diuretic, benzthiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. The following is a list of possible side effects that may occur from all constituting ingredients of Exna Tablet: vomiting, diarrhoea, photosensitivity reactions, increased in uric acid concentrations, megaloblastic anaemia, thrombocytopenia. Exna tablet may interact with the following drugs and products: ACE inhibitors, angiotensin II receptor antagonists, potassium-sparing diuretics.

Aminoglutethimide, marketing as Cytadren has been used in the treatment of advanced breast and prostate cancer. It was formerly used for its weak anticonvulsant properties. Cytadren is indicated for the suppression of adrenal function in selected patients with Cushing’s syndrome. Morning levels of plasma cortisol in patients with adrenal carcinoma and ectopic ACTH producing tumors were reduced on the average to about one half of the pretreatment levels, and in patients with adrenal hyperplasia to about two thirds of the pretreatment levels, during 1-3 months of therapy with Cytadren. Data available from the few patients with adrenal adenoma suggest similar reductions in plasma cortisol levels. Measurements of plasma cortisol showed reductions to at least 50% of baseline or to normal levels in one third or more of the patients studied, depending on diagnostic groups and time of measurement. Because Cytadren does not affect the underlying disease process, it is used primarily as an interim measure until more definitive therapy such as surgery can be undertaken or in cases where such therapy is not appropriate. Only small numbers of patients have been treated for longer than 3 months. A decreased effect or “escape phenomenon” seems to occur more frequently in patients with pituitary dependent Cushing’s syndrome, probably because of increasing ACTH levels in response to decreasing glucocorticoid levels. Cytadren blocks several other steps in steroid synthesis, including the C-11, C-18, and C-21 hydroxylations and the hydroxylations required for the aromatization of androgens to estrogens, mediated through the binding of Cytadren to cytochrome P-450 complexes. A decrease in adrenal secretion of cortisol is followed by an increased secretion of pituitary adrenocorticotropic hormone (ACTH), which will overcome the blockade of adrenocortical steroid synthesis by Cytadren. The compensatory increase in ACTH secretion can be suppressed by the simultaneous administration of hydrocortisone. Since Cytadren increases the rate of metabolism of dexamethasone but not that of hydrocortisone, the latter is preferred as the adrenal glucocorticoid replacement. Although Cytadren inhibits the synthesis of thyroxine by the thyroid gland, the compensatory increase in thyroid-stimulating hormone (TSH) is frequently of sufficient magnitude to overcome the inhibition of thyroid synthesis due to Cytadren. In spite of an increase in TSH, Cytadren has not been associated with increased prolactin secretion. At low doses, aminogluthethimide is only an effective inhibitor of aromatase (Cytochrome P450 11A1), but at higher doses, it effectively blocks Cytochrome P450 11A1 (P450scc) as well. Citadel was marketed previously as an anticonvulsant but was withdrawn from marketing for that indication in 1966 because of the effects on the adrenal gland.

Oxethazaine is a potent local anesthetic. It is administered orally (usually in combination with an antacid) for the relief of pain associated with peptic ulcer disease or esophagitis. Its effectiveness at the acidity of the gastric environment is due to the fact that oxethazaine, a weak base, is relatively non-ionized at pH 1. It is also used topically in the management of hemorrhoid pain. Oral oxetacaine preparations are available in several countries, including India, South Africa and Brazil, but not the United States. It is marketed under the name Strocain in Japan.

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.

Nialamide is a non-selective, irreversible monoamine oxidase inhibitor of the hydrazine class. It was previously used as an antidepressant (trade name Niamid) but was withdrawn by Pfizer in 1963 due to the risk of hepatotoxicity.

Ergonovine (also known as ergometrine) is the active water soluble component of ergot of rye. Ergonovine is being used as a maleate salt to prevent or treate postpartum haemorrhage and postabortion haemorrhage. Ergonovine stimulates alpha-adrenergic and serotonin receptors, thus activating contractions of uterine and vascular smooth muscle. Ergonovine may have depressant effect on CNS system as it binds to dopamine receptors.

Troleandomycin (also known Triacetyl-oleandomycin and having brand name Tao) is a macrolide antibiotic which used to for the treat of infections of the upper and lower respiratory tract: such as tonsillitis, bronchitis, sinusitis, and pneumonia. However, the brand name Tao was discontinued. Troleandomycin acts by penetrating the bacterial cell membrane and reversibly binding to the 50 S subunit of bacterial ribosomes or near the "P" or donor site so that binding of tRNA (transfer RNA) to the donor site is blocked. Translocation of peptides from the "A" or acceptor site to the "P" or donor site is prevented, and subsequent protein synthesis is inhibited.

Chlorpropamide (DIABINESE®), is a sulfonylurea hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. It appears to lower the blood glucose acutely by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. The mechanism by which chlorpropamide (DIABINESE®) lowers blood glucose during long-term administration has not been clearly established. Extra-pancreatic effects may play a part in the mechanism of action of oral sulfonylurea hypoglycemic drugs. While chlorpropamide is a sulfonamide derivative, it is devoid of antibacterial activity. Chlorpropamide (DIABINESE®) may also prove effective in controlling certain patients who have experienced primary or secondary failure to other sulfonylurea agent.

Iproniazid is a non-selective, irreversible monoamine oxidase inhibitor (MAO) of the hydrazine class. It was originally developed for the treatment of Tuberculosis, but in 1952, its antidepressant properties were discovered when researchers noted that patients given isoniazid became inappropriately happy. Iproniazid is no longer clinically prescribed and has been withdrawn due to incidences of hepatotoxicity.
