Balasubramanian S, Chowdhury YS. Nitrate dependence is possible (documented in daily industrial exposures); withdrawal manifestations (e.g., ischemic symptoms, MI, sudden death) can occur. In angina, isosorbide mononitrate and dinitrate works by widening blood vessels (veins and arteries). Conventional oral tablets: 25% unchanged drug; about half that following sublingual administration (4050%). Current guidelines recommend a combination of drug therapies (e.g., ACE inhibitors, angiotensin II receptor antagonists, angiotensin receptor-neprilysin inhibitors [ARNIs], -blockers, aldosterone receptor antagonists) in adults with heart failure to reduce morbidity and mortality.
