Clinically Significant Disseminated MAC Disease In association with the decreased incidence of bacteremia, patients in the groups randomized to either azithromycin alone or azithromycin in combination with rifabutin showed reductions in the signs and symptoms of disseminated MAC disease. This category also provides a buffer dosage zone which prevents small uncontrolled technical factors from causing dosage major discrepancies in interpretation. The dose is usually 2 grams once a day, taken as a single dose. Following the oral administration of a single.0 g dose of azithromycin (4 x 250 mg capsules the mean Cmax and AUC0-120 increased.1 and.2, respectively, in subjects with GFR 10 to 80 mL/min compared to subjects.

Concentration remained above 32 g/mL, for approximately. As the efficacy of azithromycin in the treatment of disseminated MAC has not been established, the clinical relevance of these in vitro MICs as an indicator of susceptibility or resistance is not known.

Following oral administration of multiple daily doses of 600 mg (1 tablet/day) to asymptomatic HIV-positive adults, mean maximum concentration in peripheral leukocytes was 252 g/mL (49). Drink the entire contents immediately; add an additional two dosage ounces of water, dosage mix, and drink to ensure complete consumption of dosage. The dose is usually 60 milligrams (mg) per kilogram (kg) of body weight once a day, taken as a single dose. The study was terminated early after an increased risk of relapses was observed in patients taking azithromycin compared with placebo. The high values in adults for apparent dosage steady-state volume of distribution (31.1 L/kg) and plasma clearance (630 mL/min) suggest that the prolonged half-life is due to extensive uptake and subsequent release of drug from tissues.

Analyses were performed on all randomized patients who had a positive baseline culture for MAC. A very serious allergic reaction to this drug is rare. A course of treatment involves taking only a single tablet per day for five days. Prescribing antibiotics in absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to patient and increases risk of development of drug-resistant bacteria. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light.
