Abstract

1. This study investigated the influence of age on the pharmacokinetics, pharmacodynamics, general tolerability and concentration-effect relationships in 18 patients with essential hypertension (age range 23-73 years) during treatment with dilevalol, a non selective beta-adrenoceptor antagonist with vasodilator properties. 2. There were no significant age-related changes in pharmacokinetics for either acute or chronic treatment with dilevalol, although there were significant changes in elimination half-life from 7.8 to 11.7 h (P less than 0.05) and in AUC from 261 to 352 ng ml-1 h (P less than 0.005) following translation from acute to chronic dosing. 3. In absolute terms, dilevalol treatment (as compared with placebo) produced numerically larger falls in average blood pressure in the six oldest as compared with the six youngest patients: for example, supine blood pressure fell by, respectively, 29/15 and 10/7 mm Hg during chronic treatment. 4. Using an integrated kinetic-dynamic model, blood pressure responsiveness was characterised by relating the fall in blood pressure (mmHg) to the plasma drug concentrations in each individual patient. No independent age-related effect was demonstrated. There was a significant relationship ...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.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
