Pharmacokinetic studies in men with Topicort® (desoximetasone) Ointment % with tagged desoximetasone showed no detectable level (limit of sensitivity: μg/mL) in 1 subject and and μg/mL in the remaining 2 subjects in the blood when it was applied topically on the back followed by occlusion for 24 hours. The extent of absorption for the ointment was 7% based on radioactivity recovered from urine and feces . Seven days after application, no further radioactivity was detected in urine or feces. Studies with other similarly structured steroids have shown that predominant metabolite reaction occurs through conjugation to form the glucuronide and sulfate ester.

Gentamicin, a broad-spectrum antibiotic, is a highly effective topical treatment for bacterial infections of the skin. In vitro , gentamicin is bactericidal against a wide variety of gram-positive and gram-negative bacteria isolated from domestic animals. 1,2 Specifically, gentamicin is active against the following organisms isolated from canine skin: Alcaligenes sp., Citrobacter sp., Klebsiella sp., Pseudomonas aeruginosa , indole-positive and negative Proteus sp, Escherichia coli , Enterobacter sp., Staphylococcus sp., and Streptococcus sp.

Corticosteroids are generally teratogenic in laboratory animals when adminis­tered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on terato­genic effects from topically applied corticosteroids. Therefore, topical corticoste­roids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time.
