DIGITEK (digoxin) is one of the cardiac (or digitalis) glycosides, a closely related group of drugs having in common specific effects on the myocardium. These drugs are found in a number of plants. Digoxin is extracted from the leaves of Digitalis lanata. The term "digitalis" is used to designate the whole group of glycosides. The glycosides are composed of two portions: a sugar and a cardenolide (hence "glycosides").

Durezol (difuprednate ophthalmic emulsion) 0.05% is a sterile, topical anti-infammatory corticosteroid for ophthalmic use. The chemical name is 6?,9-difuoro-11?,17,21-trihydroxypregna-1,4-diene-3,20-dione 21-acetate 17-butyrate (CAS number 23674-86-4). Difuprednate is represented by the following structural formula:

DesOwen« (desonide cream, ointment and lotion) Cream 0.05%, Ointment 0.05%, and Lotion 0.05% contain desonide (Pregna-1,4-diene-3,20-dione,11,21-dihydroxy- 16,17-[(1-methylethylidene)bis(oxy)]-,(11 ? ,16 ? )- a synthetic nonfluorinated corticosteroid for topical dermatologic use. The corticosteroids constitute a class of primarily synthetic steroids used topically as antiinflammatory and anti-pruritic agents.
