If you're dealing with a known universe of Doctors/Pharma's,...
I'd put them in a separate "Provider" table with a autonum key in it that is referenced in the combined detail table. Include the Type Field in the new table.
Ensures that spelling is consistant and that only approved Docs/Pharmas are entered. If at some point you need to add addresses or phone numbers, do it to the Provider table instead of updating all the detail records.
The rule of thumb for most data normalization is that if the same data is going to be used by many detail records, it should be in a separate table.
