Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), thereby increasing intestinal absorption and decreasing clearance of substrates; also inhibits CYP3A4 isoenzymes, reducing metabolism of CYP3A4 substrates.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site.
100 mg orally twice daily (12 hours apart) on an empty stomach (1 hour before or 2 hours after meals). Avoid milk, antacids, iron, calcium, magnesium, and zinc within 2 hours of administration.
250-500 mg orally every 6 hours or 500 mg to 1 g intravenously every 6-12 hours, not to exceed 4 g/day.

Terminal elimination half-life is approximately 18-22 hours in patients with normal renal function; prolonged to 30-50 hours in moderate renal impairment (CrCl 30-50 mL/min).
Terminal elimination half-life: 6-11 hours (mean 8 hours); prolonged in renal impairment (up to 20 hours).
Renal excretion of unchanged drug accounts for approximately 60% of the dose; fecal elimination via biliary secretion contributes about 30%; minor metabolism (<10%) produces inactive metabolites.
Renal: 60% unchanged; biliary/fecal: 40% (mainly as glucuronide conjugates).
