These 18 PowerPoints were planned as part of the IB schemes of work on Biochemistry and Medicinal Chemistry, and covers the necessary content for the all of the Standard and Higher Level units. It would also be suitable for other post-16 courses. It includes 18 full PowerPoints, along with student versions to use as notes, which have spaces for the students to add in missing information and activities for them to complete. It also includes exam questions for practice or assessment purposes Topics covered are: Pharmaceutical Products and Drug Design - Routes of drug administration - Theraputic Effects of Drugs - The Placebo Effect - Side Effects - Calculation of the Therapeutic Index - The Therapeutic Window - Bioavailability - Tolerance and Addiction - Drug Action - Drug Development by both Drug Design and Drug Discovery Aspirin and Penicillin - History of Aspirin - Method of Producing Aspirin - Calculating the % Yield of Aspirin produced from Salicyclic Acid - Effects of Aspirin - Soluble Aspirin - Development of Penicillin - Structure of Penicllin - How Penicillin Works - Antibiotic Resistance Opiates - Morphine: Structure and action;
