Among cardiovascular diseases, hypertension, angina pectoris, acute myocardial infarction and ischemic stroke present a circadian pattern with a greater incidence of unfavourable events between awakening and noon. Chronotherapy aims to use drugs that release their active principles at different times during the day, according to biological needs. In chronotherapy of cardiovascular diseases, a particular attention has been paid to slow-release drugs that assure a 24 hours therapeutic effect with once a day administration. In primary hypertension well controlled by monotherapy (dipper hypertensives), the morning administration of long-acting beta-blockers and calcium antagonists has shown to control blood pressure over 24 hours, whereas ACE-inhibitors have proved more effective when administered at evening. In secondary hypertension (non dipper hypertensives) the administration of calcium antagonists is more effective at evening. Patients with severe hypertension need polytherapy. In that case, at least one of the antihypertensive drugs should be given at evening to lower night blood pressure values, which are particularly elevated also during sleep, and so to prevent an excessive blood pressure rise on awakening. In chronic monotherapy of ischemic heart disease, long-acting beta-blockers and calcium antagonists have shown to be equally effective when they are administered at morning, whereas slow-release nitrates, which need a nitrate-free interval, are to be administered either at morning or at evening, according to the expected time of onset of anginal pain. ASA seems to reduce the morning incidence of acute myocardial infarction, while tissue-type plasminogen activator presents a circadian variation of its thrombolytic activity with a higher efficacy between noon and midnight.
