Antibiotic, Tetracycline Derivative

Officially indicated as an antibiotic for various bacterial infections. It is sometimes used off-label for post tendon repair surgery.
How does this medication work?
Doxycycline inhibits protein synthesis by binding with the 30S and possibly the 50S ribosomal subunit(s) of susceptible bacteria; may also cause alterations in the cytoplasmic membrane. Doxycycline also inhibits matrix metalloproteinases (MMP) activity which is elevated after a tendon tear/rupture. Doxycycline has been shown to accelerate tendon repair and improve the biomechanical properties of tendon, especially when paired with surgical management.
