Specifically it is a ligand of the auxiliary α2δ subunit site of certain voltage-dependent calcium channels (VDCCs), and thereby acts as an inhibitor of α2δ subunit-containing VDCCs.
Gaar ahaan waa isku xirka aaladda 'ili2δ subunit subunit' ee kanaallada kalsiyum ee ku tiirsan danabyada qaarkood (VDCCs), oo markaa waxay u dhaqmeysaa sidii ka-hortagga α2δ subunit-ku jira VDCCs.
