Considering circadian pattern of blood pressure in treatment of hypertension via chronotherapy: A conducive or a maladroit approach

Current Drug Targets
Rina Das, Dinesh Kumar Mehta


In general the concept of homeostasis has been the base for treatment of diseases. Little importance has been given in understanding biologic rhythms and their underlying mechanisms. In general most of the cardiovascular drugs are designed to accomplish a constant or near-constant effect throughout the 24-hour dosing interval. However in many cases, the requirement for medication is not the same at nighttime as it is during the day. Body rhythms may have profound effect on treatment outcomes. Medical chronobiology deals with the mechanisms of body rhythm's influences on health and diseases. Chronotherapeutics is the purposeful alteration of drug concentration to match rhythms to optimize therapeutic \outcomes and minimize size effects. It is wrongful approach to assume that a drug dosed in the morning will have the same antihypertensive effect as a drug dosed in the evening. The well documented circadian variations in blood pressure (BP), heart rate, hormone secretion, and platelet aggregation are examples of the impact of chronobiology. Based on this information, does treatment of hypertension worth a therapeutic paradigm shift? In this study we analyze the effect of circadian pattern of blood pressure on action of various ant...Continue Reading

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
