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

Need an additional free text question in case of 'other'.

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