Conditional Formatting Bold based on words

Hi, I want to use Conditional Formatting to show the words in bold if any of the following words are in the cell (see list below).

Right now, I've created a rule per word. Which means I'm going to have 20+ rules for bolding text when all is said and done. Is there anyway to avoid that? Is there a performance hit to the spreadsheet by having so many conditional formatting rules?

Words:

metformin
trulicity
bydureon
farxiga
jardiance
glimeperide
glipizide
januvia
alogliptin

statin
atorvastatin
lovastatin
simvastatin
pravastatin

lisinopril
losartan
valsartan
irbesartan

thank you!
