| abstract |
The present invention provides methods of preventing or alleviating sympathetically-enhanced conditions, neurological conditions, ocular conditions and chronic pain without concomitant sedation by peripherally administering to a subject an effective amount of an α-2A/α-1A selective agonist, thereby preventing or alleviating the condition or chronic pain without concomitant sedation, where the selective agonist has an α-1A efficacy less than that of brimonidine or a ratio of α-1A/α-2A potency greater than that of brimonidine. |
