Answer to Question 1

C
Sulfonamides can intensify the effects of some drugs, including glipizide, which is a sulfonylu-rea-type hypoglycemic medication. These drugs may require a reduction in dose to prevent tox-icity. Patients should monitor their blood glucose more closely. There is no increase in allergic reactions to TMP/SMZ in patients who are diabetic. Patients taking TMP/SMZ may need re-duced doses of glipizide but should not stop taking the drug.

Answer to Question 2

C
Use of nitroglycerine with any phosphodiesterase type 5 inhibitor, such as sildenafil or tadalafil is absolutely contraindicated. The patient should be advised to discuss another antianginal agent with the provider. Patients should be taught to increase all activity to maintain as normal a life-style as possible.
