  • Title: Prophylactic nitrate therapy in angina pectoris--is there an optimal treatment regimen?
    Author: Olsson G, Allgén J.
    Journal: Br J Clin Pharmacol; 1992; 34 Suppl 1(Suppl 1):19S-23S. PubMed ID: 1633074.
    Abstract:
    1. Nitrates have a place in the prophylactic treatment of patients with angina pectoris. Their efficacy is not in doubt. 2. However, there may be some practical problems associated with their use, such as unreliable absorption, short duration of action, treatment-induced headache, development of nitrate tolerance and a suggested rebound phenomenon observed during intermittent dosing. Furthermore, patient convenience with treatment schedule and patient compliance have to be considered during prophylactic treatment. The present article discusses how many of these problems may be solved by selection of formulation as well as nitrate compound. 3. The development of controlled-release formulations producing sufficiently high nitrate plasma concentration during part of the day followed by nitrate-poor rather than nitrate-free interval, have the potential to prevent both nitrate tolerance and rebound phenomenon, and produce a sufficiently long duration of action with a convenient once daily regimen.
