Distribution Prior norfloxacin 67% of blood plasma penetrates into peripheral tissues. concentrations in excess plasma, observed in the bile ducts, gall bladder, liver, kidney and prostate. The drug does not cross the blood-brain barrier. Plasma protein binding is about 14%. Elimination half-life of 3.5-6.5 hours. About 80% excreted by the kidneys, 20% is excreted unchanged through the intestines.

Side effect On the part of the digestive tract, liver: nausea, anorexia, diarrhea; perhaps transient increase in liver transaminases, alkaline phosphatase, lactate dehydrogenase. On the part of the central nervous system, the psyche: headache, dizziness, fatigue, drowsiness, restlessness, irritability, anxiety, confusion, hallucinations, depression, tinnitus. From the musculoskeletal skeletal system: in some cases – tendonitis, tendon rupture. From the laboratory readings: possible decrease in hematocrit, eosinophilia, leucopenia, elevated serum creatinine concentration in the plasma. Allergic reactions: seldom – urticaria, anavar for sale rash, pruritus, anaphylactic shock.

With the simultaneous use of norfloxacin with warfarin may increase the therapeutic effect of the latter.
