Résumé : Several acidic nonsteroidal anti-inflammatory drugs (NSAID) as well as their corresponding alcohol molecules which are known to induce swelling of isolated lymphocytes by changing cell membrane permeability to water, are demonstrated also to induce changes of membrane permeability of lymphoid cells to one divalent cation, calcium, and to three monovalent cations, rubidium, cesium and sodium. According to the cells ionic environment, they increase or decrease the cellular uptake of cation which is itself also closely dependent on the ionic composition of the incubation medium. This drug-effect is very rapid, directly related to the medium NSAID concentration and almost totally reversible except fo the most potent drugs such as flufenamic acid. Changes in intracellular ionic balance could have important catalytic effects on the metabolism of normal as well as of pathological cells. This fact could explain side-effects of these drugs as well as some of their therapeutic effects. © 1976 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
