Immunomodulatory properties of antihypertensive drugs and digitalis glycosides

Abstract

Introduction: The role of chronic inflammatory process in the pathogenesis or exacerbation of hypertension has been already acknowledged.

Areas covered: Therefore, one can speculate that hypotensive drugs may exert some of their therapeutic effects due to immunomodulatory properties. So far, this assumption has been tested in different studies, and the resulting knowledge is summarized in the current review article that is dedicated to different groups of antihypertensives, namely calcium channel blockers, beta blockers, as well as other less commonly used medications, such as hydralazine, alfa-2 receptor agonists, diazoxide, doxazosin, aliskiren, and sodium nitroprusside. Articles were found in the Pubmed by entering the name of a specific drug/group of drugs with the words: immunology, cellular response, humoral response, inflammation, interleukin. The 2000-2021 range was used to search for all drugs except propranolol (1980-2021) and calcium blockers (1990-2021).

Expert opinion: Observed decrease in serum/plasma concentration of proinflammatory cytokines, and CRP along with lower expression of adhesion molecules on immune cells strongly suggest that these drugs possess immunomodulatory properties, which seems to be crucial in the medical practice, especially in the therapy of hypertensive patients with other accompanying inflammatory-based diseases, such as type II diabetes, developed metabolic syndrome, allergies or autoimmunity.
