Pharmacology degree can lead to jobs in clinical trial ,medical sales or general jobs say like banking , providing you have some sort of experience or passion for it. most jobs require a degree to show your competant and the problem is that regardless of what sector you go into they require experience of some sort.
good jobs are medical sales, however to break into it, you must have a contact, as many will require that you at least have shadowed sombody using your own contacts so that you know what the job involves etc.
to break into clinical trials you probably would have to graduate and then take a very low paid role such as :
http://www.reed.co.uk/jobs/research-assistant/23244648#/jobs/scientific/clinical-research-trialsstay with them for at least 2 years and then do a masters or PHD so that you can take senior positions (maybe inhouse). now as you can see already you have 57 applications for that one job, so i would advise that you also work voluntary for some companies shadowing, or take internships and also help out in your local youth club, and also be involved with your council in community projects, as these things help you stand out from the crowd and helps you build contacts. ( dont be a lazy arse like me
) regardless of whatever jobs you apply for or course, people love extra curricular activities such as mentioned above.
now pharmacology does not involve formulation, so you wont be making drugs. for that you need
pharmaceutical science which is almost the same as pharmacy but without dispensing and pharmacy law . and will most likely need to do a masters etc for a specific job role.
pharmacy involves pharmacology, formulations and drug dispensing. its a masters degree hence 4 years and dont think that all it involves in sitting in a chemist giving drugs out. with pharmacy you can do all of the above job roles. you can work for GSK or Astra zeneca as a pharmacist making formulations or carrying out clinical trials working alongside pharmacologists etc. most people open pharmacies or work in them because the pay is good and life is stress free. however if want to make drugs or do trials i suggest you start working hard now. these companies look for high achievers and people with a high drive for success, they usually have placements and summer camps for A levels students, with limited places available. i think your probs passed the deadline now though!!
my advice is pick pharmacy avoid pharm sci or pharmacology,
also at what stage of education are ya and what grades you got??
