All of the following are true regarding vancomycin except: September 2009
Correct Answer: Poorly distributed in the body fluids
Description: Ans. B: Poorly distributed in the body fluids Vancomycin undergoes limited absorption when administered orally and is therefore restricted to parenteral administration for the treatment of systemic infections. It is distributed widely to various tissues and body fluids. Penetration of vancomycin may vary by site and concomitant disease states. For example, limited CSF penetration may be enhanced by the presence of inflamed meninges. The orable penetration of vancomycin into skin tissues may be significantly impaired in patients with diabetes. Vancomycin penetration into lung epithelial lining fluid is limited relative to that of simultaneous serum concentration (the ratio of lung tissue to serum concentration is about 0.25). Vancomycin's primary route of elimination is renal excretion of unchanged drug. The rate of elimination is directly related to creatinine clearance. Rapid intravenous injection may cause chills, fever, uicaria and intense flushing-called 'red man syndome'.
