Following oral administration, azithromycin is rapidly absorbed (T max = 2-3 hours) and distributed widely throughout the body. Rapid movement of azithromycin from blood into tissue results in significantly higher azithromycin concentrations in tissue than in plasma (up to 50 times the maximum observed concentration in plasma). The absolute bioavailability is approximately 37%. When azithromycin suspension was administered with food to 28 adult healthy male subjects, the rate of absorption (C max ) was increased by 56% while the extent of absorption (AUC) was unchanged. Food does not affect the absorption of azithromycin in the tablet dosage form. Azithromycin tablets and powder for oral suspension can be taken with or without food. A DULT P HARMACOKINETICS Plasma concentrations of azithromycin decline in a polyphasic pattern, resulting in an average terminal half-life of 68 hours. The prolonged half-life is likely due to extensive uptake and subsequent release of drug from tissues. Over the do Lue koko asiakirja
