Abstract
A controlled-release organic nitrate formulation for once-per-day oral administration is provided by spheres having a core which includes an organic nitrate, and a membrane surrounding the core composed of a pharmaceutically acceptable, film forming polymer. The film forming polymer is effective to permit release of the organic nitrate from the spheres, over a daily dosing period, at a rate that achieves a therapeutically effective level of the organic nitrate, while effecting a drug holiday towards a latter portion of the daily dosing period so as not to induce tolerance.
