Azithromycin, an antibiotic, has an apparent volume of distribution of approximately 30 l/kg. what is the main interpretation of this information?
The apparent volume of distribution of the antibiotic azithromycin is about 30 l/kg. This means that 30L/Kg is the theoretical volume required to hold the entire drug dose supplied at the same blood plasma concentration.
The imaginary fluid volume across which medicine is disseminated is the apparent volume of distribution (Vd) for that particular agent. It is computed by dividing the total dosage given by the plasma drug concentration.
The volume of distribution is helpful in estimating the dose required to achieve a given plasma concentration as A = C ·Vd, with A = amount of drug in the body ( ≈ dose, shortly after administration) and C = plasma concentration.
Many bacterial infections can be treated with azithromycin, an antibiotic drug. This covers pneumonia, traveler's diarrhea, strep throat, middle ear infections, and other intestinal ailments.
