Requirements:
Apparatus Required:
Mortar & pestle, weigh balance sieve shaker, China dish etc.
Chemical Required:
Sodium phosphate, sodium bicarbonate, tartaric acid.
Principle:
Effervescent preparation provides effervescence of CO2 gas when added to water by a chemical
reaction between alkali metal carbonates or bicarbonates with tartaric acid or citric acid. This
preparation is intended to be dissolved in water before it is being taken orally. The CO2 gas is released
as a result of acid-base reaction. The preparation is advised to be taken while effervescence.

Mehta R.M., Dispensing Pharmacy, Vallabh Prakashan, New Delhi, 2017; 115
Requirements:
Apparatus Required: Mortar & pestle, weigh balance, sieve shaker etc.
Chemical Required: Purified talc, starch, zinc oxide
Principle:
Dusting powders are usually mixtures of two or more substances in fine powder intended for external
use. Starch possess binding as well as good flow property which helps the powder to flow easily,
spread uniformly and cling to the skin on application. Talc is natural mineral substance zinc oxide is
protectant.
Formula:
Sl. No. Ingredients Official formula Working formula Required quantities
1 Purified talc 1gm
2 Starch 0.5gm
3 Zinc oxide 0.5gm 30gm
Calculation:
Procedure:
Weigh the required quantity of purified talc and zinc oxide.
Mix zinc oxide with starch and incorporate purified talc.
Mix thoroughly and pass the mixed powder through a sieve no.120 to remove gritty particles.
After sieving whole of the powder must be again slightly mixed.
Pack the powder to protect it from air, moisture and contamination.
Storage: Store in a well closed container and should be kept in a cool place.
