Monovalent and divalent inorganic cations

Monovalent and divalent inorganic cations, such as sodium (Na+), potassium (K+), calcium (Ca2+), and magnesium (Mg2+), are essential chemical species that underpin nearly all physiological processes. They are critical for maintaining cellular osmotic balance, generating electrical impulses in excitable tissues, and serving as secondary messengers in complex signaling cascades [1][2]. While these ions are not biological macromolecules like receptors or enzymes, they are the primary focus of numerous therapeutic strategies aimed at correcting electrolyte imbalances or modulating physiological functions through ion channel and transporter activity [3]. For instance, lithium is used to treat bipolar disorder by potentially competing with other cations, while calcium channel blockers are used to manage hypertension [4]. Because of their pervasive roles, any significant deviation from homeostatic levels can result in severe clinical manifestations, including cardiac arrest, seizures, or bone density loss [5].

Drugs interact with these cations by modulating their transport across cell membranes via ion channels, pumps, and transporters, or by direct supplementation or chelation to alter systemic concentrations.
