Volume of Distribution

Asidox diffuses readily into most body tissues, fluid and/or cavities and the volume of distribution has been measured as 0.7 L/kg .

Half Life

16.33 hr (± 4.53 sd) .

Clearance

The excretion of doxycycline by the kidney is about 40% over 72 hours in individuals with normal kidney function (creatinine clearance approximately 75 mL/min). This rate may fall as low as 1-5% over 72 hours in individuals with severe renal insufficiency (creatinine clearance below 10 mL/min). Some clinical studies have shown no major difference in serum half-life of doxycycline (range 18-22 hours) in patients with normal and severely impaired renal function. Hemodialysis does not affect serum half-life of doxycycline .

Pregnancy: Asidox should be avoided in pregnant women, because of the risk of both staining and effect on bone growth in the fetus.

Lactation: Asidoxs enter breast milk, and mothers taking these drugs should not breastfeed their child.
