Cefbuperazone (cefalosporin antibiotic) is marketed under the brand name Keiperazon by Kaken, and Tomiproan by Toyama, Japan. It is powder for injection 0.5 and 1 g/ampoule. It is indicated to treat infections with susceptible microorganisms. It has been proposed especially against Pseudomonas infections. Cefbuperazone binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall.

Fenbufen is a nonsteroidal anti-inflammatory drug, developed for the treatment of symptoms associated with such disease as rheumatoid arthritis. Fenbufen acts through its active metabolite, 4-biphenylacetic acid which is a potent inhibitor of COX1 and COX2 enzymes. Fenbufen was found to cause skin rash and liver toxicity and was withdrawn from the market.

Ornidazole is nitroimidazole derivative. It is an antiprotozoal drug that has proven to be effective against Trichomonas vaginalis, Entoamoeba histolytica, Giardia lamblia and Helicobacter pylori. The reduction of the nitro group and the generation of short-lived reactive intermediates are the basis of its parasiticidal activity. Ornidazole is a DNA-tropic drug with selective activity against microorganisms with enzyme systems capable of reducing the nitrogroup and catalyze the interaction between ferrodoxin proteins and nitrocompounds. After the drug penetrates the microbial cell, the mechanism of its action is based reducing the nitrogroup under the influence of the microorganism’s nitroreductases and the activity of the reduced nitroimidazole. The reduction products create compounds with DNA causing it to degrade, and disrupt the DNA replication and transcription processes. Furthermore, the drug’s metabolism products have cytotoxic properties and disrupt cellular respiration processes. It is indicated for the treatment of anaerobic systemic infections caused by ornidazole-sensitive microflora, prevention of infections caused by anaerobic bacteria, during operative treatment (especially middle and straight intestine surgeries), gynecological surgeries, severe intestinal ameobiasis, all extra-intestinal ameobiasis forms, giardiasis. Ornidazole was shown to be effective for the prevention of recurrence of Crohn's disease after ileocolonic resection.

Indoprofen is one of several NSAIDs that have been withdrawn from the market due to causing severe gastrointestinal bleeding. The UK Licensing Authority suspended the product license on grounds of safety in 1983 and in 1984 the Italian manufacturers decided to withdraw it from the world market. The UK decision was taken because there was a high rate of adverse drug reactions in a voluntary postmarketing surveillance study and the spontaneous adverse reaction reporting system had noted 217 serious adverse effects, mainly gastrointestinal bleeding and perforation.

Fluocortolone is a topical corticosteroid (class of steroid hormones formed in the adrenal gland). Is primary indicated in condition like, Ana fissure, Dermatosis haemorrhoids, proctitis. The signs and symptoms that are produced after the acute overdosage include convulsions, respiratory arrest, allergic skin reactions. Glucocorticoids, such as fluocortolone, act through nuclear hormone receptors Schaaf and Cidlowski (2002). The two members of this family are glucocorticoid receptor (GR) type I and GR type I I. Activation of these sites alters gene expression of endogenous agents that influence immune and inflammatory responses.

Ipronidazole is an antiprotozoal drug of the nitroimidazole class used in veterinary medicine. Ipronidazole (2-isopropyl-1-methyl-5-nitroimidazole) is used for the treatment of histomoniasis in turkeys and in swine dysentery.

Xipamide is a diuretic of thiazide class. It is used for the treatment of hypertension and edema. The diuretic effect of the drug is due to reduction of sodium reabsorption and increase in potassium excretion.

Ronidazole is an antiprotozoal agent. Ronidazole and the other nitroimidazole derivatives damage DNA following reduction of the nitro group. It is used in veterinary for prevention and treatment of various infections including histomoniasis in turkeys, trichomoniasis in pigeons, genital trichomoniasis in cattle, haemorrhagic enteritis in pigs and Tritrichomonas foetus in cats.

Roxithromycin is a semi-synthetic macrolide antibiotic, which was developed by Roussel Uclaf and is available in Australia. Roxithromycin prevents bacteria from growing, by interfering with their protein synthesis. Roxithromycin binds to the subunit 50S of the bacterial ribosome, and thus inhibits the translocation of peptides. It can treat respiratory tract, urinary and soft tissue infections.

Rafoxanide is a halogenated salicylanilide used as a fasciolicide in cattle, sheep, goats, and horses. It is also active against nematodes, and the sheep nasal bot fly. Rafoxanide acts as by uncoupling oxidative phosphorylation of flukes, including reduced ATP levels, decreased glycogen content and accumulation of succinate.
