VASO CONSTRUCTION PREPARATIONS AND PROCEDURES FOR USE THEREOF

摘要

The invention generally relates to compositions and methods for preferential vasoconstriction of smaller blood vessels relative to larger blood vessels. The compositions comprise highly selective alpha-2 adrenergic receptor agonists, at low concentrations, such as below 0.05% weight by volume. The compositions preferably comprise brimonidine. The compositions preferably have pH between about 5.5 and about 6.5.
