Pharmaceutical Technology and Legislation I
A.Y. 2024/2025
Learning objectives
The course aims to introduce the principles underlying the design, preparation and control of the main conventional and modified release pharmaceutical dosage forms. The course enables the students to acquire the necessary knowledge to understand the relationships between technological, biopharmaceutical and pharmacokinetic properties of medicinal products. Rationales and strategies to develop different dosage forms are defined, with particular regard to those intended for oral administration.
Expected learning outcomes
At the end of the course the student will have acquired skills in pharmaceutical technology that are fundamental for the industrial development, production and control of oral medicinal products.

Course syllabus
Biopharmaceutics: classification of dosage forms; conventional and non conventional dosage forms; gastrointestinal transit, drug plasma concentration-time curves; pharmacokinetic parameters; concepts of bioavailability and bioequivalence; absolute and relative bioavailability; L.A.D.M.E.; physiological factors affecting bioavailability; dissolution process (Noyes-Whitney equation); technological factors affecting bioavailability; bioequivalence; biopharmaceutics classification system (BCS)
· Preformulation: wettability, solubility and dissolution rate; Henderson-Hasselbalch equation; approaches to the enhancement of solubility and dissolution rate. Solid state properties (amorphous form, polymorphs, solvates, salts, cocrystals) and techniques for their characterization
· Oral solid dosage forms: general scheme for the preparation of solid dosage forms; properties of powders, analysis of powders; pharmaceutical processing (process and equipment): milling, mixing, granulation, pelletisation, drying, tabletting, coating (sugar coating and film-coating); formulation and manufacture aspects of powders, granules, pellets, tablets, capsules, lozenges; tests for solid oral dosage forms.
· Oral liquid dosage forms: general scheme for the preparation of liquid dosage forms; general pharmaceutical processing; formulation and manufacture aspects of drops, syrups, etc..

Assessment methods and Criteria
Learning assessment includes a written test lasting 1 hour, based on 2 open-ended questions and an oral interview. To be admitted to the oral exam the student must gain a minimum mark of 18/30 for both questions. The oral interview, lasting about 40 minutes, entails an in-depth and critical discussion of the topics addressed in the course, divided into 3 or more questions. The final mark results from a weighted evaluation of the answers
