There are a total of 10 tablets of 0.5 g of the drug are required for a 20-day duration.
Drugs may be defined as any chemical or natural substances that are utilized in order to prevent, diagnose, treat, or relieve symptoms of a disease or abnormal condition.
According to the question, the total weight of the patient = 110 lb.
Now, convert this weight into kg = 110 × 0.454 = 49.89 kg ≅ 50 kg.
The total amount of drug that is prescribed = 50 × 5 = 250 mg.
The dose is prescribed twice a day = 250 × 2 = 500 mg.
As we double the amount of drugs, so we can half the number of days.
The total amount of drug = 500 × 10 = 5000 mg.
Now, convert the amount of this drug into tablet form of 0.5 g.
5000/500 = 10.
Therefore, there are a total of 10 tablets of 0.5 g of the drug are required for a 20-day duration.
