NIHR BioResource Questionnaire - medication list

The NIHR BioResource questionnaire includes a section for participants to list their long-term medication.

Our intention is to build up a picking list for this, compiled from the answers given by participants, and add to it as the recruitment process expands.

There is a dm+d browser at ​http://www.ppa.org.uk/systems/pcddbrowserv2_3new/browser.jsp#product which is a good place to look up correct drug names and dose information.

Accept free text entry for the first batch. Then data cleansing exercise to build a category list.

Provisional list:

Allopurinol Amlodipine Aspirin Atorvastatin Bisoprolol Candesartan Digoxin Febuxostat Furosemide Gaviscon Advance Glyceryl trinitrate Indapamide Isosorbide mononitrate Lansoprazole Lisinopril Perindopril Pramipexole Ramipril Rosuvastatin Simvastatin Spironolactone Warfarin

Question: how do we record drug trial medication? Add an option at the bottom of the list for 'Unknown study drug'?
