Question

a patient is to receive 25 mg of methimazole, a drug used to treat hyperthyroid conditions. the drug is dissolved in solution containing 6.0 mg/mL

Answer 1

The drug has a concentration of 6 mg per 1 ml. Therefore, to know that number of ml containing 25 grams, we will simply do cross multiplication as follows:
amount of drug = (25 x 1) / 6 = 4.1667 ml

Therefore, for the patient to receive 25 mg of methimazole, he/she should take 4.1667 ml of the drug solution.
