From the earliest civilizations, man has used as a way to achieve improvement in different diseases vegetable products, mineral, animal or synthetic in recent times. The health care was in the hands of people who exercise dual function of doctors and pharmacists.Doctors are actually preparing their own healing remedies, some of them coming to achieve great renown in his time, such as the Greek Galen (130-200). From it comes the name of the Galenic, as the proper way to prepare, dispense and administer drugs. In Roman culture there were many ways to manage the substances used to cure diseases. Thus, using the electuaries as a mixture of powders of various medicinal herbs and roots which are added a portion of fresh honey. Honey besides being the substance which serves as a vehicle for the active substances, the best flavor was prepared. Sugar used occasionally. Also used a syrup , which already contained the sugar dissolved in water again and the whole was prepared by forming a pasty mass. Precisely Galen famously great antidote to which he devoted an entire work, and that was coming electuary to contain over 60 different active ingredients. Galen's importance in the Middle Ages, became very popular during this time leaving to be authorized for use in Spain in the middle of the twentieth century .
It is in the Middle Ages where the pharmacist began operating separately from the doctor. In his pharmacy conducts its compounded preparations, understood as the preparation for each patient individualized remedies prescribed, and are grouped in associations with doctors. The revival is being produced a clearer separation of the pharmaceutical activity against physicians, surgeons and spice, while leaving a revolution in knowledge that stands as pharmaceutical science in the modern age. The compounding is the basis for the pharmaceuticals formulation together with officinal, due to the birth and proliferation of pharmacopoeias and forms, and this continues until the second half of the nineteenth century.
From this point begin to appear specific, consisting of industrially produced medicinal products for pharmaceutical laboratories. Thus, the dosage forms not acquire real prominence until around 1940, when the pharmaceutical industry develops and they begin to be manufactured in large quantities. From then until today the ways in which drugs are evolved and the diversity found in the market is very wide.
