BRISTACYCLINE vs TETRACHEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRISTACYCLINE is a tetracycline antibiotic that reversibly binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
250 mg orally every 6 hours for 7-14 days.
500 mg orally once daily for 28 days; for severe infections, 500 mg twice daily for 14 days.

6-12 hours (terminal). In renal impairment, half-life extends up to 24-48 hours; dose adjustment required for CrCl <30 mL/min.
6-11 hours (prolonged in renal impairment; up to 57 hours in anuria).
Renal (40-60% unchanged), fecal (20-30%, primarily as inactive metabolites). Biliary excretion contributes minimally (<5%).
Renal 60% (glomerular filtration), fecal 40% (biliary excretion of active drug and metabolites).
