    Area of Science:

    • Pharmacology
    • Biochemistry
    • Physiology

    Background:

    • Calcium channel antagonists are crucial molecules for inhibiting calcium channel function.
    • Existing research provides collective evidence for their inhibitory role.
    • Key questions regarding their precise mechanisms and sites of action persist.

    Purpose of the Study:

    • To explore the mechanisms and sites of action of calcium channel antagonists.
    • To investigate the heterogeneity of these agents and their potential for tissue selectivity.

    Main Methods:

    • Radioligand binding assays were employed.
    • Analysis of biochemical, chemical, clinical, pharmacological, and physiological studies was conducted.
    • Review of existing compounds and their observed tissue selectivity.

    Main Results:

    • Evidence supports multiple sites and mechanisms of action for calcium channel antagonists.
    • The chemical and pharmacological heterogeneity of these agents is highlighted.
    • Existing compounds demonstrate varying degrees of tissue selectivity.

    Conclusions:

    • The existence of multiple sites and mechanisms for calcium channel antagonists is supported.
    • This complexity necessitates further experimentation to delineate specific interactions.
    • The findings indicate a strong potential for developing novel, tissue-selective calcium channel antagonists.
