In addition, if combined with Sustiva, the following drugs may require a change in the dose of either Sustiva or the other medicine: Ritadin (ritampin); Sporanox (itraconazole); Nizoral (ketoconazole); calcium-channel blockers
(for example, Cardizem, Tiazac, and others); and the cholesterol-lowering medications Lipitor (atorvastatin), Pravachol (pravastatin), and Zocor (simvastatin).
Thirteen trials with 91,561 participants, meeting inclusion criteria, compared beta-blockers with placebo (4 trials; n=23,613), diuretics (5 trials; n=18,241), calcium-channel blockers
(4 trials; n=44,825), and renin-angiotensin system inhibitors (3 trials; n=10,828).
First, regarding her comparison of expensive calcium-channel blockers
for hypertension with "over-the counter" diuretics: The diuretics are inexpensive and very effective, but do require a prescription.
