Among the medications listed for Patient #1, which drug is NOT associated with xerostomia?

• A. Hydrochlorothiazide
• B. Metoprolol
• C. Tamsulosin
• D. Pravastatin

Answer: (D)

Xerostomia occurs when saliva production is reduced, often from drugs with anticholinergic effects or from dehydration caused by a medication. Among these drugs, hydrochlorothiazide can lead to dehydration from increased urine output, which lowers saliva flow. Metoprolol can cause xerostomia in some individuals due to autonomic effects on salivary glands. Tamsulosin is less commonly associated with dry mouth, though rare cases can occur. Pravastatin, a statin, does not typically affect saliva production or cause dehydration, so it is not associated with xerostomia. Therefore, pravastatin is the drug not associated with xerostomia.
