Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bacteriostatic antibiotic that reversibly binds to the 30S ribosomal subunit, inhibiting protein synthesis by preventing attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site.
200 mg orally or intravenously once, followed by 100 mg every 12 hours; maximum 400 mg/day.
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: 11–17 hours (mean ~15 hours in normal renal function); prolonged to 18–30 hours in renal impairment; context: allows twice-daily dosing, but accumulation can occur in hepatic/renal dysfunction.
Terminal elimination half-life: 6-11 hours (mean 8 hours); prolonged in renal impairment (up to 20 hours).
Renal (approximately 10% unchanged; higher in impaired renal function), biliary/fecal (major route via feces as unchanged drug and metabolites, up to 70% overall elimination through hepatobiliary system).
Renal: 60% unchanged; biliary/fecal: 40% (mainly as glucuronide conjugates).
