Pharmaceutical powders are solid, composed of uniform
particles of one or more active substances, with or without
auxiliary substances and are used as such or divided in
unit doses.
Powders can be administered orally or may be applied
to the skin or mucous membranes (powder).
Powders applied on wounds, burns and on infants skin
are prepared by methods that ensure their sterility
(Romanian Pharmacopoeia) and that avoid a subsequent
contamination with microorganisms.
