This book aim is to simplify pharmacology, by making it fun easily understood by students studying nursing, medicine and pharmacy. I have a profound love for pharmacology as it was the first course that I taught independently and the results were marvelous. One day while reflecting on my time throughout nursing school, I remembered that some of us had difficulties grasping the concept of remembering the medication class, mechanism of action etc. Then on June 20th 2020 at 6:04 p.m. I started to write the book. I believe the content is easy to grasp and it is very straightforward for those studying for the Regional Examination for Nurse Registration (RENR) in Jamaica, other nursing licensure examinations in the Caribbean and also the NCLEX.
