How much menthol is required to compound a formula reading: 'camphor 0.3%, menthol 0.25%, hydrocortisone 1%, Aquaphor q.s. ad 600 g'?

Rationale

1500 mg of menthol is required to compound the formula.

To determine the amount of menthol needed in the formula, we calculate 0.25% of the total weight of the compounded formula, which is 600 g. This calculation results in 1500 mg of menthol.

A (15 mg) YOUR ANSWER

This choice underestimates the required amount of menthol. To find 0.25% of 600 g, which is 1.5 g or 1500 mg, is significantly higher than 15 mg. Therefore, this option does not meet the criteria set by the formula.

B (150 mg) YOUR ANSWER

While this choice is closer than option A, it still does not reflect the correct calculation for 0.25% of 600 g. The correct calculation yields 1500 mg, meaning 150 mg is only 10% of the required amount, making this choice incorrect.

C (1500 mg) CORRECT

Calculating 0.25% of 600 g gives us 1.5 g, which converts to 1500 mg. This is indeed the precise amount of menthol needed as per the formula specifications, confirming this option as correct.

D (15 g) YOUR ANSWER

This option significantly overestimates the needed amount of menthol. Since 15 g converts to 15000 mg, it far exceeds the calculated requirement of 1500 mg. Hence, this choice is not valid for the given formulation.

Conclusion

To accurately compound the formula specified, the amount of menthol required is determined by calculating 0.25% of 600 g, resulting in 1500 mg. This ensures the formulation meets the required concentrations of its components, while all other options either underestimate or overestimate the necessary amount of menthol. Proper calculations are essential in pharmaceutical formulations to guarantee efficacy and safety.
