Explanation / Answer

Ans. Given- Total amount of Triamcinolone acetonide to be prepared = 35.0 g

            Triamcinolone acetonide content = 0.1 %

            Methanol = 1 %

            Camphor = 1%

# Required amount of Triamcinolone acetonide = 0.1% (w/w) of 35.0 g = 0.035 g

Required amount of methanol = 1% (w/w) of 35 g = 0.35 g

Required amount of camphor = 1% (w/w) of 35 g = 0.35 g

# Required amount of cream base = Total mass – Mass of all other ingredients

                                                = 35.0 g – (0.035 + 0.35 + 0.35) g

                                                = 34.265 g

# Preparation: To 34.265 g cream base, add 0.035 g Triamcinolone acetonide and 0.35 g of methanol and camphor each. Mix well to get a homogenous gel. It is the desired cream.
