Powders are solid dosage forms consisting of a mixture of finely divided drugs and/or chemicals intended for internal or external use. They are one of the oldest dosage forms used in pharmacy.
Powders offer flexibility in dosing and rapid drug absorption, but may have issues such as poor taste, instability, and difficulty in administration.
Powders should be stored in well-closed containers, protected from moisture, light, and contamination to maintain stability and efficacy.
