DistributionWidely distributed into tissues and body fluids; crosses placenta and enters breast milk.

Protein BindingApproximately 80-90% bound to plasma proteins.

MetabolismPartially metabolized in the liver.

Half-Life18-22 hours (single dose); may be shorter with repeated doses.

How It Works

Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing addition of amino acids to growing peptide chains.

Mechanism Steps

1Doxycycline enters bacterial cells via passive diffusion and active transport.

2Binds reversibly to the 30S ribosomal subunit.

3Prevents binding of aminoacyl-tRNA to the mRNA-ribosome complex.
