The present invention is directed towards new chemical entities which primarily inhibit the human T-type calcium channels and differentially modulate other key ion channels to control cell excitability, and abnormal neuronal activity particularly involved in the development and maintenance of persistent or chronic pain, and / or neurological disorders. These novel compounds are useful in the treatment and prevention of neurological and psychiatric disorders and diseases in which these ion channels are involved. The invention is also directed towards pharmaceutical formulations comprising these compounds and the uses of these compounds.
