Hiyah!
You'll do a Statistics course in the first year that deals with the mathematical skills you might need to analyse clinical trials data, pharmaceutical science experiments etc, and the pharmacokinetics probably 2nd/3rd year. This is mainly equations that look at rates of drug distribution and metabolism in the body, as well as things like bioavailability, e.g. what percentage of a drug gets used and how it being in tablet/injection/liquid form might alter that. I would say the percentages are probably 10% phys and maths (the physics comes into things like fluid dynamics when you look at the manufacturing of tablets for example), 30% chemistry-related, 30% biology-related and 30% clinical-related. But the biology is quite chemical in that its pharmacology and biochem with a small amount of physiology rather than a large amount of anatomy and physiology like the medics. If anyone has a different estimate feel free to say as its quite hard to judge with some pharmacy modules as they are so specialised. xx
