Catalogo dei Corsi di studio

The aim of
this course is to give detailed informations on dosage forms and in particular
will discuss problems about preparation and formulation of conventional dosage
forms referring to their
biotechnological applications.

Prerequisites

TECNOLOGIE FARMACEUTICHE The student must have: 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 and 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)

Exam modes

TECNOLOGIE FARMACEUTICHE
The exam consists of an oral exam, in which the student have to demonstrate abilities in classifying conventional dosage forms and in evaluating the features of excipients.
To obtain a final grade of 18/30 (minimum mark) student must demonstrate to possess basic knowledge and skills related to compounding and control of conventional dosage forms.
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 this knowledge in different working environments.
