Sulfasalazine is an anti-inflammatory indicated for the treatment of ulcerative colitis and rheumatoid arthritis. The mode of action of Sulfasalazine or its metabolites, 5-aminosalicylic acid (5-ASA) and sulfapyridine (SP), is still under investigation, but may be related to the anti-inflammatory and/or immunomodulatory properties that have been observed in animal and in vitromodels, to its affinity for connective tissue, and/or to the relatively high concentration it reaches in serous fluids, the liver and intestinal walls, as demonstrated in autoradiographic studies in animals. In ulcerative colitis, clinical studies utilizing rectal administration of Sulfasalazine, SP and 5-ASA have indicated that the major therapeutic action may reside in the 5-ASA moiety. The relative contribution of the parent drug and the major metabolites in rheumatoid arthritis is unknown. Sulfasalazine is used for the treatment of Crohn's disease and rheumatoid arthritis as a second-line agent. Sulfasalazine is marketed under the trade name Azulfidine among others.

Oxycodone is a semisynthetic opioid used for the management of acute and chronic pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Oxycodone is a highly selective full agonist of the μ-opioid receptor (MOR), with low affinity for the δ-opioid receptor (DOR) and κ-opioid receptor (KOR). After oxycodone binds to the MOR, a G protein-complex is released, which inhibits the release of neurotransmitters by the cell by reducing the amount of cAMP produced, closing calcium channels, and opening potassium channels. After a dose of conventional (instant-release) oral oxycodone, the onset of action is 10–30 minutes, and peak plasma levels of the drug are attained within roughly 30–60 minutes in contrast, after a dose of OxyContin (an oral controlled-release formulation), peak plasma levels of oxycodone occur in about three hours. The duration of instant-release oxycodone is 3 to 6 hours, although this can be variable depending on the individual. Oxycodone in the blood is distributed to skeletal muscle, liver, intestinal tract, lungs, spleen, and brain. Serious side effects of oxycodone include reduced sensitivity to pain (beyond the pain the drug is taken to reduce), euphoria, anxiolysis, feelings of relaxation, and respiratory depression. Common side effects of oxycodone include constipation (23%), nausea (23%), vomiting (12%), somnolence (23%), dizziness (13%), itching (13%), dry mouth (6%), and sweating (5%).

Targets:
4-AMINOSALICYLIC ACID (Paser) is an anti-tuberculosis drug used to treat tuberculosis in combination with other active agents. 4-AMINOSALICYLIC ACID (Paser) is most commonly used in patients with Multi-drug Resistant TB (MDR-TB) or when isoniazid and rifampin use is not possible due to a combination of resistance and/or intolerance. There are two mechanisms responsible for aminosalicylic acid's bacteriostatic action against Mycobacterium tuberculosis. Firstly, aminosalicylic acid inhibits folic acid synthesis (without potentiation with antifolic compounds). The binding of para-aminobenzoic acid to pteridine synthetase acts as the first step in the folic acid synthesis. Aminosalicylic acid binds pteridine synthetase with greater affinity than para-aminobenzoic acid, effectively inhibiting the synthesis of folic acid. As bacteria are unable to use external sources of folic acid, cell growth and multiplication slow. Secondly, the aminosalicylic acid may inhibit the synthesis of the cell wall component, mycobactin, thus reducing iron uptake by M. tuberculosis.

Proguanil is a prophylactic antimalarial drug, which works by stopping the malaria parasite, Plasmodium falciparum and Plasmodium vivax, from reproducing once it is in the red blood cells. Proguanil in combination with atovaquone are marked under the brand name malarone, which is indicated for the treatment of acute, uncomplicated P. falciparum malaria and for the prophylaxis of Plasmodium falciparum malaria, including in areas where chloroquine resistance has been reported. Atovaquone and proguanil, interfere with 2 different pathways involved in the biosynthesis of pyrimidines required for nucleic acid replication. Atovaquone is a selective inhibitor of parasite mitochondrial electron transport. Proguanil hydrochloride primarily exerts its effect by means of the metabolite cycloguanil, a dihydrofolate reductase inhibitor. Inhibition of dihydrofolate reductase in the malaria parasite disrupts deoxythymidylate synthesis. Recently were done experiments, which confirmed the hypothesis that proguanil might act on another target than dihydrofolate reductase. In addition, was made conclusion, that effectiveness of malarone was due to the synergism between atovaquone and proguanil and may not require the presence of cycloguanil.

Ascorbic acid (vitamin C) is a water-soluble vitamin. It occurs as a white or slightly yellow crystal or powder with a slight acidic taste. Ascorbic acid is an electron donor, and this property accounts for all its known functions. As an electron donor, ascorbic acid is a potent water-soluble antioxidant in humans. Ascorbic acid acts as an antioxidant under physiologic conditions exhibiting a cross over role as a pro-oxidant in pathological conditions. Oxidized ascorbic acid (dehydroascorbic acid (DHA) directly inhibits IkappaBalpha kinase beta (IKKbeta) and IKKalpha enzymatic activity in vitro, whereas ascorbic acid did not have this effect. These findings define a function for vitamin C in signal transduction other than as an antioxidant and mechanistically illuminate how vitamin C down-modulates NF-kappaB signaling. Vitamin C is recommended for the prevention and treatment of scurvy. Its parenteral administration is desirable for patients with an acute deficiency or for those whose absorption of orally ingested ascorbic acid (vitamin c) is uncertain. Symptoms of mild deficiency may include faulty bone and tooth development, gingivitis, bleeding gums, and loosened teeth. Febrile states, chronic illness, and infection (pneumonia, whooping cough, tuberculosis, diphtheria, sinusitis, rheumatic fever, etc.) increase the need for ascorbic acid (vitamin c). Hemovascular disorders, burns, delayed fracture and wound healing are indications for an increase in the daily intake.

Pyridoxine is the 4-methanol form of vitamin B6 and is converted to pyridoxal 5-phosphate in the body. Vitamin B6 (pyridoxine) is a water-soluble vitamin used in the prophylaxis and treatment of vitamin B6 deficiency and peripheral neuropathy in those receiving isoniazid (isonicotinic acid hydrazide, INH). Vitamin B6 has been found to lower systolic and diastolic blood pressure in a small group of subjects with essential hypertension. Hypertension is another risk factor for atherosclerosis and coronary heart disease. Another study showed pyridoxine hydrochloride to inhibit ADP- or epinephrine-induced platelet aggregation and to lower total cholesterol levels and increase HDL-cholesterol levels, again in a small group of subjects. Vitamin B6, in the form of pyridoxal 5'-phosphate, was found to protect vascular endothelial cells in culture from injury by activated platelets. Endothelial injury and dysfunction are critical initiating events in the pathogenesis of atherosclerosis. Human studies have demonstrated that vitamin B6 deficiency affects cellular and humoral responses of the immune system. Vitamin B6 deficiency results in altered lymphocyte differentiation and maturation, reduced delayed-type hypersensitivity (DTH) responses, impaired antibody production, decreased lymphocyte proliferation and decreased interleukin (IL)-2 production, among other immunologic activities. Used for the treatment of vitamin B6 deficiency and for the prophylaxis of isoniazid-induced peripheral neuropathy.

Biotin (also known as vitamin H and vitamin B7) is a water-soluble vitamin which is required for normal cellular functions, growth and development. Biotin is an important cofactor for many mitochondria and cytoplasm enzymes: acetyl-CoA carboxylase a (ACCa),7 ACCb, pyruvate carboxylase (PC), propionyl-CoA carboxylase (PCC), and methylcrotonyl-CoA carboxylase (MCC) and plays critical role in in the intermediate metabolism of gluconeogenesis, fatty acid synthesis, and amino acid catabolism. The vitamin cannot be synthesized by humans and must be obtained from diet. If there is a lack of biotin, an organism starts suffering from biotin deficiency, a condition which is very common among pregnant women, for example. The vitamin deficiency effects hair, nail growth and skin health. For preventing measures, biotin should be taken as a dietary supplement (in a form of vitamin complex or as a pure biotin) which are marketed worldwide under different names. Biotin is a part of many formulations which were approved by FDA.

Panthenol (pantothenol) is an alcohol form of the B5 vitamin pantothenic acid. It easily penetrates the skin retaining water and is a humectant, emollient and moisturizer. Panthenol mitigates signs of inflammation and stimulates epithelization. Panthenol comes in two enantiomers, D and L. Only D-panthenol (dexpanthenol) is biologically active, however both forms have moisturizing properties. Because of the ability to attract and hold moisture panthenol is used in skincare products as a humectant. It also has a role as provitamin (called pro-vitamin B5) and is used as a vitamin supplement in complex ( M.V.I. ADULT injection, Hospira Worldwide, Inc.) and alone, and as a cholinergic drug. Panthenol is a highly viscous transparent liquid at room temperature, but salts of pantothenic acid (sodium pantothenate) are powders (typically white). It is soluble in water, alcohol, propylene glycol, ether and chloroform, and slightly soluble in glycerin. Panthenol mixes readily with many different types of ingredients, making it a versatile ingredient to be used in formulas because it improves skin’s barrier function and maintains the proliferation of fibroblasts. In organisms it is quickly oxidized to pantothenate (pantothenic acid). Defficiency of Vitamin B5 results in many dermatological disorder. Due to the fact that only D-Panthenol is converted to Vitamin B5 and not L-Panthenol, the racemic mixture of D- and L- panthenol (DL-panthenol) has only half of the physiological activity of the D-Panthenol. These include stimulation of epithelisation, wound healing effect and anti-infl ammatory effect. Panthenol is FDA approved for cosmetic use and comes either in D form, or as a racemic mixture. It is also in the FDA list of over-the-counter drug products that are not generally recognized as safe and effective or are misbranded: as "Insect Bite and Sting Drug Products" and "Poison Ivy, Poison Oak, and Poison Sumac Drug Products".
