Tosufloxacin is a fluoroquinolone antibacterial agent. Tosufloxacin is an inhibitor of bacterial DNA gyrase and topoisomerase IV. Tosufloxacin is indicated for the treatment of various infections such as skin, respiratory, urinary, gynecologic, ophthalmologic, otolaryngologic, dental infections. Fluoroquinolones including tosufloxacin have a potential risk of inducing cartilage and joint toxicity in children. It is also associated with severe thrombocytopenia and nephritis, and hepatotoxicity.

(R)-Timolol is the (R)-enantiomer of non-selective Beta antagonist Timolol. (R)-Timolol is a ß-adrenergic blocking agent that binds only to nonspecific sites in the particulate fraction of the heart, lungs, and brain. (R)-Timolol is an antihypertensive agent that increases ocular blood flow and reduces intraocular pressure. (R)-Timolol is one of the impurities in commercial formulation of (S)-Timolol.

Fimasartan is a angiotensin II receptor antagonist which was developed in Korea for the treatment of hypertension. The drug is available in different forms: Kanarb, Dukarb (in combination with Amlodipine), Tuvero (in combination with Rosuvastatin). Fimasartan was tested to be effective in Mexican and Russian population and now is being tested in the USA.

Oral dehydroemetine dihydrochloride (+/-) (Mebadin) was found useful both as a tissue and contact amoebicide. It is much less toxic and more active than emetine and can be given in larger doses and for longer periods with safety. Owing to the quick excretion, repeat courses can be given at short intervals, as necessary, without danger. No serious side effects were noted particularly with the oral form and it was far better tolerated by children, who received relatively higher dosage than most adults. The only contra-indication is for patients with manifest decompensation of vital organs, or fevers. Mebadin injection and Mebadin tablets are discontinued products.

Etilamfetamine (Apetinil) is a stimulant drug of amphetamine chemical class. It is an N-substituted amphetamine with an ethyl group on the amphetamine backbone. It was used as an anorectic or appetite suppressant. Etilamfetamine is a psychoactive drug, which can be used as a recreational drug.

Azapropazone is a non-steroidal anti-inflammatory drug. It is indicated for use in the treatment of rheumatoid arthritis, osteo-arthritis and gout. Gastro-intestinal disturbances, allergic skin rashes and photosensitivity, headache, vertigo, oedema and kidney impairment may occur. Gastro-intestinal bleeding and angioedema have been reported. Pre-treatment with this drug failed to modify plasma concentrations of phenobarbitone. Brain levels of imipramine or desmethyl imipramine were unaffected 60 minutes after oral administration of imipramine.
