There is a long thread based on this topic already within this subforum, but basically
Pharmacy = MPharm = degree you have to do to be a practising pharmacist in the UK. Includes A LOT of science around drug mechanisms and illnesses and how to treat them, as well as clinical skills such as counselling and advice for patients
Pharmacology = not pharmacy = degree centred around drug mechanisms and interactions = a small part of the pharmacy degree, leading to jobs in labs mainly doing various things.
Im studying the MPharm - its extremely difficult but will be worth it in the end
