CHEMICAL CONNECTIONS 1A Drug Dosage and Body Mass In many cases, drug dosages are prescribed on the ba- sis of body mass. For example, the recommended dos- age of a drug may be 3 mg of drug for each kilogram of body weight. In this case, a 50 kg (110 lb) woman would receive 150 mg and an 82 kg (180 lb) man would get 246 mg. This adjustment is especially important for children, because a dose suitable for an adult will generally be to0 much for a child, who has much less body mass. For this reason, manufacturers package and sell smaller doses of certain drugs, such as aspirin, for Children's Dosing Chart Age (yr) Dose (tsp) Weight (Ib) under 2 yr ask a doctor under 24 b 24-35 Ib 2-3 yr 1 tsp 4-5 yr 1 1/2 tsp 36-47 ib children. 2 tsp 48-59 Ib 6-8 yr Drug dosage may also vary with age. Occasionally, when an elderly patient has an impaired kidney or liver function, the clearance of a drug from the body is de- layed, and the drug may stay in the body longer than is normal. This persistence can cause dizziness, vertigo, and migraine-like headaches, resulting in falls and bro- ken bones. Such delayed clearance must be monitored and the drug dosage adjusted accordingly. 9-10 yr 2 1/2 tsp 60-71 Ib 11 yr 3 tsp 72-95 Ib Grape a Liquid 2-11 This package of Advil has a chart showing the proper doses for children of a given weight.
