CVS makes knock-off Biotene products. I always preferred its mouth spray to Biotene's. I was just at my local CVS store and saw that the CVS Mouthwash has enzymes listed in it's contents so, hopefully, their Biotene knock-offs across the board will have enzymes. However, I don't know if CVS has any additional dry mouth products beside these two.
