For long-acting nitrates, what is the recommended nitrate-free interval?

Explanation:
Long-acting nitrates lose their effectiveness when used without a break because tolerance develops with continuous exposure. To keep them working, you need a daily nitrate-free interval that lets the vascular system reset and regain responsiveness. The option that provides a daily off period best reflects this approach, balancing ongoing protection with preventing tolerance. Continuous dosing would worsen tolerance, a full 24-hour off would leave you unprotected for a day, and a very short off period isn’t long enough to reverse tolerance. In practice, a daily off interval is what preserves efficacy.
