Do Medicines Like Diamicron And Coversyl Cause Dry Mouth?

My friend is suffering with a very dry mouth and believes it is one of her medications or a combination of one or more. These are the medications she is on and wants to aske her dr if something should be changed.
Diamicron, Coversyl, Losec, Zandip, Plavix, Nexium, Physiotens, Lyrica, Zocor, Mobic and Tarsiac.
My friend is aged and does not have a computer.
Thanking you
Pam
