Prescribing-label excerpts
Minocycline Hydrochloride
Reference for: Minocycline Hcl. Source presentation: tablet, film coated, extended release. Source route: oral.
Mechanism of action
The mechanism of action of minocycline hydrochloride extended-release tablets for the treatment of acne is unknown.
Pharmacokinetics
Minocycline hydrochloride extended-release tablets are not bioequivalent to non-modified release minocycline products. Based on pharmacokinetic studies in healthy adults, minocycline hydrochloride extended-release tablets produce a delayed T maxat 3.5 to 4.0 hours as compared to a non-modified release reference minocycline product (T maxat 2.25 to 3 hours). At steady-state (Day 6), the mean AUC (0–24) and C maxwere 33.32 mcg×hr/mL and 2.63 mcg/mL for minocycline hydrochloride extended-release tablets and 46.35 mcg×hr/mL and 2.92 mcg/mL for minocycline hydrochloride capsules, respectively. These parameters are based on dose adjusted to 135 mg/day for both products.
A single-dose, four-way crossover study demonstrated that minocycline hydrochloride extended-release tablets used in the study (45 mg, 90 mg, 135 mg) exhibited dose-proportional pharmacokinetics. In another single-dose, five-way crossover pharmacokinetic study, minocycline hydrochloride extended-release tablets 55 mg, 80 mg, and 105 mg were shown to be doseproportional to minocycline hydrochloride extended-release tablets 90 mg and 135 mg.
When minocycline hydrochloride extended-release tablets were administered concomitantly with a meal that included dairy products, the extent and timing of absorption of minocycline did not differ from that of administration under fasting conditions.
Minocycline is lipid soluble and distributes into the skin and sebum.
