Need Creon 25

I am a pediatrician who regularly goes to the Dominican Republic on medical missions. I have been involved in the care of Yendry, a 7 year old there with CF, for years. We supply or finance as much of his medications as possible, though the treatment he receives there is limited due to his and our resources. We are currently having problems finding Creon 25 at an affordable price. Does anyone have any ideas on how or where we can get this at an affordable price? I can gladly accept donations of medications if you are no longer using them or if they are slightly expired. Thank you so much.
