These materials have been created in order to help students understand the basic maths required in order to carry out those drug calculations. The materials have been designed using one method of calculations, for alternative methods and advice please see the recommended books on this page or discuss with your tutors.

This advice is for a number of different courses. Please check with your module leader as to which guidance is most relevant to you.
