Abstract

Biaryl substituted triazole compounds represented by Formula I, II or III, or pharmaceutically acceptable salts thereof, and a process for making such compounds and salts thereof. Pharmaceutical compositions comprise an effective amount of the instant compounds, either alone, or in combination with one or more other therapeutically active compounds, and a pharmaceutically acceptable carrier. Methods of treating conditions associated with, or caused by, sodium channel activity, including, for example, acute pain, chronic pain, visceral pain, inflammatory pain, neuropathic pain, epilepsy, irritable bowel syndrome, depression, anxiety, multiple sclerosis, and bipolar disorder, comprise administering an effective amount of the present compounds, either alone, or in combination with one or more other therapeutically active compounds. A method of administering local anesthesia comprises administering an effective amount of a compound of the instant invention, either alone, or in combination with one or more other therapeutically active compounds, and a pharmaceutically acceptable carrier.
