๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionDoxycycline is almost completely absorbed after oral administration; Serratiopeptidase is absorbed from the gastrointestinal tract.
DistributionDoxycycline is widely distributed in body tissues and fluids; Serratiopeptidase distributes to inflamed tissues.
Protein BindingDoxycycline: 80-93% protein bound; Serratiopeptidase: not well characterized.
MetabolismDoxycycline is partially metabolized in the liver; Serratiopeptidase is metabolized by proteolysis.
Half-LifeDoxycycline: 18-22 hours; Serratiopeptidase: approximately 6-8 hours.
ExcretionDoxycycline: primarily excreted in feces (via bile) and urine; Serratiopeptidase: excreted in urine and feces.
BioavailabilityDoxycycline: ~90-100%; Serratiopeptidase: not well defined.
Onset of ActionDoxycycline: within 1-2 hours; Serratiopeptidase: within 1 hour.
Peak Plasma TimeDoxycycline: 2-4 hours; Serratiopeptidase: 1-2 hours.
Duration of ActionDoxycycline: 24 hours; Serratiopeptidase: 6-8 hours.

How It Works

Doxycycline inhibits bacterial protein synthesis by binding to 30S ribosomal subunit; Serratiopeptidase reduces inflammation by breaking down fibrin and other proteins.

Mechanism Steps

1Doxycycline enters bacterial cells via passive diffusion and active transport.
2Binds reversibly to 30S ribosomal subunit, blocking aminoacyl-tRNA binding to mRNA-ribosome complex.
3Inhibits bacterial protein synthesis, leading to bacteriostatic effect.
