The exact mechanism of action behind these activities is unknown. The aim of our work was to study the effect of cannabidiol (CBD), tetrahydrocannabinol and 11-nor-9-carboxy-tetrahydrocannabinol on cellular cardiac electrophysiological properties including ECG parameters, action potentials, hERG and I<sup>Kr<\/sup>\u00a0ion channels in HEK cell line and in rabbit and guinea pig cardiac preparations. CBD increased action potential duration in rabbit and guinea pig right ventricular papillary muscle at lower concentrations (1\u00a0\u00b5M, 2.5\u00a0\u00b5M and 5\u00a0\u00b5M) but did not significantly change it at 10\u00a0\u00b5M. CBD at high concentration (10\u00a0\u00b5M) decreased inward late sodium and L-type calcium currents as well. CBD inhibited hERG potassium channels with an IC<sub>50<\/sub>\u00a0value of 2.07\u00a0\u00b5M at room temperature and delayed rectifier potassium current with 6.5\u00a0\u00b5M at 37\u00a0\u00b0C, respectively. The frequency corrected QT interval (QTc) was significantly lengthened in anaesthetized guinea pig without significantly changing other ECG parameters. Although the IC<sub>50<\/sub>\u00a0value of CBD was higher than literary Cmax\u00a0values after CBD smoking and oral intake, our results raise the possibility that hERG and potassium channel inhibition might have a role in the possible proarrhythmic adverse effects of cannabinoids in situations where metabolism of CBD impaired and\/or the repolarization reserve is weakened.<\/p>\n","protected":false},"featured_media":0,"template":"","products_tags":[44],"resource_type":[75],"application_areas":[50],"therapeutic_areas":[54],"target_categories":[61],"target_families":[333],"targets":[92],"resource_keyword":[],"class_list":["post-6456","resource_library","type-resource_library","status-publish","hentry","products_tags-patchliner","resource_type-publication","application_areas-ion-channels","therapeutic_areas-cardiac-safety-cipa","target_categories-voltage-gated-ion-channels","target_families-kv-channels","targets-kv11-1-herg"],"acf":[],"_links":{"self":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library\/6456","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_library"}],"about":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/types\/resource_library"}],"wp:attachment":[{"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/media?parent=6456"}],"wp:term":[{"taxonomy":"products_tags","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/products_tags?post=6456"},{"taxonomy":"resource_type","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_type?post=6456"},{"taxonomy":"application_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/application_areas?post=6456"},{"taxonomy":"therapeutic_areas","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/therapeutic_areas?post=6456"},{"taxonomy":"target_categories","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_categories?post=6456"},{"taxonomy":"target_families","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/target_families?post=6456"},{"taxonomy":"targets","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/targets?post=6456"},{"taxonomy":"resource_keyword","embeddable":true,"href":"https:\/\/nanion.com\/zh-hans\/wp-json\/wp\/v2\/resource_keyword?post=6456"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
