a) Good command of specific technical expression.
b) mastery of elementary algebra (properties of logarithms, operations with numbers in scientific notation, fractions and percentages) of elementary geometry and trigonometry.
c) In order to understand the contents of the lessons and to achieve the learning objectives, it is necessary that the student know the key competences related to General and Inorganic Chemistry, Organic Chemistry, Physics courses (unit of concentration, conversion operations of the main measurement units, definition and measurement units of the main physical quantities, physical state and phase transition processes, thermodynamics, colligative properties, pH effect and ionization, buffer systems, formulas and structures of organic substances, general aspects of organic reactions).

Teaching mode
The course provides lectures aimed to provide the main scientific and technological knowledge necessary to the evaluation of the influence of physicochemical properties of drugs, dosage forms and routes of administration on the rate and extent of drug absorption. The course gives information on formulation and classification of non-conventional drug delivery systems.
The students will acquire also the fundamentals on National and CEE pharmaceutical laws and in particular on the ones governing the profession of pharmacist.
During the lessons the teacher stimulates active participation of the student: at the end of each lesson the teacher asks questions to the students in order to have a feedback to verify the correct learning in order to modify the teaching activities in a more effective way, stimulating the self-directed learning.
The active participation of the students in the lesson is completed by practical exercises: in fact, numerical exercises and exercises aimed to apply the theoretical bases of biopharmaceutics for the evaluation of the usefulness multiple-dosage regimen are proposed, in order to promote flipped-classroom teaching.
The introduction of a differentiated approach into the educational process helps to individualize the learning process of students, contributes to a more lasting and deeper acquiring of knowledge, the formation of positive motivation to learning, creation of a comfortable learning environment, building students’ self-esteem and making them more autonomous.
Frequency
Compulsory attendance at face-to-face classes
Exam mode
The exam consists of two parts: a written test and an oral test.
Oral exam can only be taken if the written exam has been successfull (minimum mark: 18/30).
During the written exam it is forbidden to use books, notes, reports on practical activities carried out in the laboratory, PC, smartphone and any device that allows access to the internet.
During the oral exam the student have to demonstrate abilities in pharmaceutical technology concerning the non-conventional dosage forms; understand the relationships between biopharmaceutics, technology and pharmacokinetic; acquire also the fundamentals on pharmaceutical laws and on laws governing the profession of pharmacist, the National Health system, the regional health system, the production and the marketing authorization of medicines and of health product with particular regard to the national and European laws and the general fundamentals on socio-economics, pharma-economics, marketing and merchandising.
To obtain a final grade of 18/30 (minimum mark) student must demonstrate to possess basic knowledge and skills related to preformulation, biopharmaceutics and the basic ability to understand the law aspects of the pharmacy system and of the regional and national healthcare system.
To obtain a final grade of 30/30 cum laude, student must demonstrate to possess an excellent knowledge of the overall addressed arguments, with the ability to think critically in a logic and coherent way. The student must also demonstrate to have understood the key and characterizing elements to be able to spend the professional abilities of pharmacist in different working environments.
In case of failure, both the written and the oral test need to be repeated.
