Transdermal patches are used in medicine to deliver a specific amount of medication through the skin and into the
bloodstream, and then to the injury that will be treated. The diffusion process involved in this method was modeled using
cartesian coordinates and it was solved using Laplace transformation, Bromwich integral and the residue theorem. The
solution obtained in cartesian coordinates was given in terms of Fourier series. The cumulative amount of drug released
at time t was calculated and it is represented as an infinite series of decreasing exponentials. It’s expected that the
analytic results obtained will be useful for pharmaceutical engineering.
