FERROSOFERRIC OXIDE is a black ore of iron. It is a coloring matter used in the pharmaceutical industry as a coating pigment.

Azelaic acid, a naturally occurring saturated dicarboxylic acid found in wheat, rye, and barley, possesses antimicrobial activity, affects keratin production, and reduces inflammation. One of the brand name for azelaic acid is FINACEA,Gel, 15% is indicated for topical treatment of the inflammatory papules and pustules of mild to moderate rosacea. Although some reduction of erythema, which was present in patients with papules, and pustules of rosacea occurred in clinical studies, efficacy for treatment of erythema in rosacea in the absence of papules and pustules has not been evaluated. Rosacea is a common skin condition thought to be primarily an inflammatory disorder. Neutrophils, in particular, have been implicated in the inflammation associated with rosacea and mediate many of their effects through the release of reactive oxygen species. Many effective agents for rosacea, including topical azelaic acid have anti-inflammatory properties. Azelaic acid per se has multiple modes of action in rosacea, but an anti-inflammatory effect achieved by reducing reactive oxygen species appears to be the main pharmacological action. A possible mechanism of action for azelaic acid in the human epidermis includes its possibility to inhibit tyrosinase and of membrane-associated thioredoxin reductase enzymes, this enzyme is shown to regulate tyrosinase through a feedback mechanism involving electron transfer to intracellular thioredoxin, followed by a specific interaction between reduced thioredoxin and tyrosinase.

Sevoflurane is a general anesthetic that is FDA approved for the induction and maintenance of general anesthesia in adult and pediatric patients for inpatient and outpatient surgery. Sevoflurane induces a reduction in junctional conductance by decreasing gap junction channel opening times and increasing gap junction channel closing times. Sevoflurane also activates calcium dependent ATPase in the sarcoplasmic reticulum by increasing the fluidity of the lipid membrane. It also appears to bind the D subunit of ATP synthase and NADH dehydogenase and also binds to the GABA receptor. Common adverse reactions include cardiovascular: bradyarrhythmia, hypotension, gastrointestinal: nausea, vomiting, neurologic: somnolence, psychiatric: agitation, respiratory: cough, interrupted breathing and other: shivering.

Mycophenolic acid (MPA) possesses antibacterial, antifungal, antiviral, immunosuppressive and anticancer properties. Mycophenolic acid (MPA) is a fungal metabolite that was initially discovered by Bartolomeo Gosio in 1893 as an antibiotic against anthrax bacillus, Bacillus anthracis. It is an uncompetitive and reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH), and therefore inhibits the de novo pathway of guanosine nucleotide synthesis without incorporation to DNA. It was approved under the brand name Myfortic for the prophylaxis of organ rejection in adult patients receiving a kidney transplant and is indicated for the prophylaxis of organ rejection in pediatric patients 5 years of age and older who are at least 6 months post kidney transplant. Myfortic is to be used in combination with cyclosporine and corticosteroids.

Dexrazoxane is a cardioprotective drug used in patients with breast cancer to reduce cardiomyopathy associated with doxorubicin administration. Dexrazoxane is believed to act by two mechanisms: it inhibits DNA topoisomerase II and acts as a chelator for iron ions.

Metformin is the most widely used drug to treat type 2 diabetes, and is one of only two oral antidiabetic drugs on the World Health Organization (WHO) list of essential medicines. Metformin is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. However, we still do not completely understand its mechanisms of action. The main effect of this drug from the biguanide family is to acutely decrease hepatic glucose production, mostly through a mild and transient inhibition of the mitochondrial respiratory chain complex I. In addition, the resulting decrease in hepatic energy status activates AMPK (AMP-activated protein kinase), a cellular metabolic sensor, providing a generally accepted mechanism for the action of metformin on hepatic gluconeogenesis. The use of metformin, the most commonly prescribed drug for type 2 diabetes, was repeatedly associated with the decreased risk of the occurrence of various types of cancers, especially of pancreas and colon and hepatocellular carcinoma.

Carvedilol competitively blocks β1, β2 and α1 receptors. The drug lacks sympathomimetic activity and has vasodilating properties that are exerted primarily through α1-blockade. Animal models indicate that carvedilol confers protection against myocardial necrosis, arrhythmia and cell damage caused by oxidising free radicals, and the drug has no adverse effects on plasma lipid profiles. COREG® (carvedilol) is a racemic mixture in which nonselective β-adrenoreceptor blocking activity is present in the S(-) enantiomer and α1-adrenergic blocking activity is present in both R(+) and S(-) enantiomers at equal potency. Carvedilol is the first drug of its kind to be approved for the treatment of congestive heart failure, and is now the standard of care for this devastating disease. Carvedilol is also confirmed as effective in the management of mild to moderate hypertension and ischaemic heart disease.

Technetium Tc 99m Bicisate is a Radioactive Diagnostic Agent indicated as an adjunct to conventional computed tomography (CT) or magnetic resonance imaging (MRI) in the localization of stroke in patients in whom stroke has already been diagnosed. Technetium Tc 99m Bicisate is a lipophilic complex with high first-pass extraction fraction and deposition and retention in the brain in proportion to cerebral blood flow. Its radionuclide emissions permit external imaging of the cerebral distribution of the agent, thus allowing the detection of altered regional cerebral perfusion. The retention in the brain of technetium Tc 99m Bicisate results from in vivo metabolism (de-esterification) of the primary complex to polar, less diffusable compounds Technetium Tc-99m Bicisate is metabolized by endogenous enzymes to the mono- and di-acids of Technetium Tc-99m Bicisate that can be detected in blood and urine. Technetium Tc-99m Bicisate is excreted primarily through the kidneys. Within two hours, 50% of the injected dose is excreted and by 24 hours, 74% is found in urine.

Budesonide is a glucocorticoid used in the management of asthma, the treatment of various skin disorders, allergic rhinitis and ulcerative colitis. The precise mechanism of corticosteroid actions on inflammation in asthma is not well known. Inflammation is an important component in the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of inhibitory activities against multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in allergic- and non-allergic-mediated inflammation. The anti-inflammatory actions of corticosteroids may contribute to their efficacy in asthma. Commonly reported side effects of budesonide include: acne vulgaris, moon face, and bruise. Other side effects include: ankle edema, hirsutism, weakness, arthralgia, nausea, and rhinitis. Ketoconazole, a potent inhibitor of cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4), the main metabolic enzyme for corticosteroids, increased plasma levels of orally ingested budesonide.

Indium In-111 is used in specialized diagnostic applications, for example, with indium-111 labelled antibodies. It is useful for labelling blood cell components. Other applications include labelling of platelets for thrombus detection, labelled leukocytes for localization of inflammation and abscesses, as well as leukocyte kinetics. Indium forms a saturated (1:3) complex with oxyquinoline. The complex is neutral and lipidsoluble, which enables it to penetrate the cell membrane. Within the cell, indium becomes firmly attached to cytoplasmic components; the liberated oxyquinoline is released by the cell. It is thought likely that the mechanism of labeling cells with indium In 111 oxyquinoline involves an exchange reaction between the oxyquinoline carrier and subcellular components which chelate indium more strongly than oxyquinoline. Indium In-111 oxyquinoline is indicated for radiolabeling autologous leukocytes. Indium In-111 oxyquinoline labeled leukocytes may be used as an adjunct in the detection of inflammatory processes to which leukocytes migrate, such as those associated with abscesses or other infection, following reinjection and detection by appropriate imaging procedures. The degree of accuracy may vary with labeling techniques and with the size, location and nature of the inflammatory process. Sensitivity reactions (urticaria) have been reported. The presence of fever may mask pyrogenic reactions from indium In 111 oxyquinoline labeled leukocytes. Indium In-111 Chloride is a diagnostic radiopharmaceutical intended for radiolabeling OncoScint (satumomab pendetide) or ProstaScint (capromab pendetide) used for in vivo diagnostic imaging procedures and for radiolabeling Zevalin (ibritumomab tiuxetan) in preparations used for radioimmunotherapy procedures.
