[The galenic pharmacy in the development of new drugs]

After having regarded the drug dosage form as a simple presentation of the active substance, the pharmaceutical world is convinced that the drug substance activity is not only controlled by its molecular structure but also by the galenical formulation as well as the manufacturing methods of the drug dosage forms. The galenical research in universities and in pharmaceutical companies gave rise to a new generation of dosage forms called "drug delivery systems" which have often taken advantage of the potential of new administration routes and have definitely found an important place in both human and veterinary therapeutics.
