Minocycline is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the binding of aminoacyl-tRNA to the mRNA-ribosome complex.

100 mg orally or intravenously every 12 hours for 24 hours, then 100 mg every 12 hours; severe infections: 200 mg initially, then 100 mg every 12 hours.
250-500 mg orally every 6 hours or 500 mg orally every 12 hours (maximum 2 g/day)

Terminal elimination half-life is 11–17 hours in patients with normal renal function; prolonged up to 18–69 hours in renal impairment.
6-12 hours; prolonged in renal impairment (up to 24-48 hours in anuria)
Primarily renal (approximately 70% unchanged) and biliary/fecal (approximately 30%, with enterohepatic recycling).
Renal (60-80% unchanged via glomerular filtration), biliary/fecal (20-40%)
