Metronidazole is used in the treatment of anaerobic protozoal infections. Although often administered orally, it can also be delivered by means of an IV infusion. The loading dose is 15 mg per kilogram of body mass and is infused over one hour. The maintenance dose is 7.5 mg per kilogram of body mass, is also infused over an hour, and is administered six hours after the loading dose. If the concentration of the metronidazole solution is 5 mg/ml, how many...
For many drugs, it is important to adjust the dose for individual patients. A patient's body weight or body surface area (BSA) is sometimes used for estimating drug dosages for children and for estimating the starting dosage for chemotherapy for cancer patients. BSA is difficult to measure directly, but it may be calculated by the following formula based on height and weight. BSA = 71.84W0.425H0.725, where BSA is measured in square centimeters, W is weight in kilograms, and H is...

Diazepam is used as a skeletal muscle relaxant and as a sedative administered before surgery, as well as a treatment for anxiety. For children above the age of 6 months who suffer from anxiety disorders, diazepam is administered at a reduced dosage. Suppose a child with a body surface area (BSA) of 0.8 m2 is to receive a dose of diazepam divided into three administrations. Using the BSA rule and assuming that an adult dose of diazepam is 12 mg,...
