Learning outcomes of the course unit

Release and Targeting of drugs is an advanced course of Pharmaceutical Technology giving the knowledge for the innovative dosage form preparation. Objective of the course is to give to the student the knowledge for designing, developing and manufacturing dosage forms
that for their complexity are sometime called therapeutical system. Together with the essential notions of pharmaceutical technology, the base knowledge of biopharmaceutics, pharmacokinetics and diffusion or mass transport will be given. In addition, the materials, mechanisms and devices adopted in the fundamental operations for the achievement of drug release control and targeting will be treated.

Prerequisites

Base pharmaceutical technology knowledge is required.

Course contents summary

The course is divided in three sections:
First part is dedicated to the administration route and mechanisms of drug absorption.Specia attention is given to the compartmental pharmacokinetics.
The second part is addressed to the comprehension of the mechanisms of substance transport in order to have the basis for understanding the drug delivery systems performance.
The third part consists in the application of the knowledge obtain din the previous sections to the construction and control of the drug delivery systems.

Course contents

- Bioavailability and Bioequivalence
- Administration routes of drugs
- Drug delivery control: story, fundamentals and applications
- Solubility, specific surface area and dissolution rate of drugs and drug
products
- Mass transport or diffusion: Fick law, thin film diffusion, membrane
transport, free diffusion.
- Natural and synthetic polymers: biodegradable, cellulose derivatives,
PVA, PVC, PEG, PLA, PLGA...
- Devices for drug release control: reservoir and matrix
