A medication pill (here assumed to be spherical of radius a) is produced by compressing together a small amount of active ingredient with a binding (and processing) powder. The active ingredient diuses through the pill 'matrix' into the stomach and then into the blood stream. (After the release of the active ingredient the pill matrix breaks up.) The release rate is medically important and may be adjusted by changing the amount active ingredient and binder, and level of compression used When producing the pill. A model of the diffusion process within the pill is given by: g = 5V2c in 1'
