Abstract
Particulate nedocromil sodium with a mass median diameter of from 5 to 10 .mu.m is useful as a medicament for inhalation. The particulate nedocromil sodium of the invention is particularly advantageous in that its dispersion, i.e. the proportion of particles which are capable of penetrating deep into the lung, is substantially greater than the dispersion of conventional powders having smaller mass median diameters.
