Example the string BaciTRACIN + Neomycin + Polymyxin B Topical should be BaciTRACIN+Neomycin+Polymyxin B Topical.

Jm - use the Find and Replace feature... easily found by hitting the ctrl + h together.

Type in the "Find what:" section the text string as follows: (leading space) + (following space)

Replace with: + (no spaces)

Worked for me.
