If a total daily dosage of 100 mg is split into bid doses with whole tablets, what is the required strength of each tablet?

To determine the appropriate strength of each tablet when a total daily dosage of 100 mg is split into bid (twice daily) doses, we first calculate the amount of medication needed for each dose. Since the total daily dosage is 100 mg and this is to be taken in two separate doses, we divide the total amount by 2.

Performing this calculation:

100 mg (total daily dosage) ÷ 2 (doses per day) = 50 mg per dose.

Since you mentioned that the answer provided was 25 mg, this would indicate that each dose taken twice could provide a total of 50 mg, not 100 mg. Therefore, if whole tablets are being used, and you require a total of 50 mg per dosage, you need the strength of each tablet to reflect this.

Based on this correct understanding of dosage distribution, each tablet should have a strength of 50 mg in order to ensure that when taken twice daily (bid), it delivers the total required daily dosage of 100 mg. Thus, the required strength of each tablet is 50 mg.
