PHARMACOLOGY: Gentamicin, a broad-spectrum antibiotic, is a highly
effective topical treatment for bacterial infection 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 ., Staphlyococcus sp .
and Streptococcus sp .
The most common side effect of topical corticosteroid use is skin atrophy. All topical steroids can induce atrophy, but higher potency steroids, occlusion, thinner skin, and older patient age increase the risk. The face, the backs of the hands, and intertriginous areas are particularly susceptible. Resolution often occurs after discontinuing use of these agents, but it may take months. Concurrent use of topical tretinoin (Retin-A) % may reduce the incidence of atrophy from chronic steroid applications. 30 Other side effects from topical steroids include permanent dermal atrophy, telangiectasia, and striae.
A loading dose is not required. Typically, 85% of the steady-state concentration is achieved after three daily Mycamine doses.
No dosing adjustments are required based on race, gender, or in patients with severe renal dysfunction or mild-to-moderate hepatic insufficiency. The effect of severe hepatic impairment on micafungin pharmacokinetics has not been studied.
No dose adjustment for Mycamine is required with concomitant use of mycophenolate mofetil, cyclosporine, tacrolimus, prednisolone, sirolimus, nifedipine, fluconazole, voriconazole, itraconazole, amphotericin B, ritonavir, or rifampin.
