AMNESTEEM vs ISOTRETINOIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Retinoid that binds to and activates retinoic acid receptors (RARs), thereby normalizing keratinocyte differentiation and reducing sebum production.
Reduces sebum production, inhibits sebaceous gland activity, and induces apoptosis in sebocytes. Binds to retinoic acid receptors (RARs) and retinoid X receptors (RXRs) to regulate gene expression.
0.5-1.0 mg/kg/day orally in 2 divided doses
0.5-1 mg/kg/day orally in two divided doses for 15-20 weeks; cumulative dose 120-150 mg/kg.

Terminal elimination half-life: 10-20 hours (mean 17 hours) in patients with normal renal function; prolonged in severe renal impairment
Clinical Note
moderateIsotretinoin + Estrone sulfate
"The therapeutic efficacy of Estrone sulfate can be decreased when used in combination with Isotretinoin."
Clinical Note
moderateIsotretinoin + Estramustine
"The therapeutic efficacy of Estramustine can be decreased when used in combination with Isotretinoin."
Clinical Note
moderateIsotretinoin + Dienogest
"The therapeutic efficacy of Dienogest can be decreased when used in combination with Isotretinoin."
Clinical Note
moderateIsotretinoin + Medroxyprogesterone acetate
Terminal elimination half-life is approximately 20 hours (range 10-30 hours) for the parent drug. Clinical significance: steady-state achieved in ~5 days with repeated dosing; prolongation in renal impairment is minimal.
Renal (65-83% as unchanged drug and metabolites), fecal (15-35% as metabolites)
Primarily hepatic metabolism; metabolites excreted in urine (65-80%) and feces (15-35%). Less than 1% excreted unchanged in urine.
