Recently, we reported the successful application of a novel mathematical model describing drug disposition in eye compartments to simulate disposition of clonidine after topical (eye drop) administration. This example extends the methodology to describe the disposition of timolol in different eye tissues and plasma after topical administration. Timolol is a nonselective beta-adrenoceptor antagonist used to lower intraocular pressure (IOP). A serious disadvantage of ocular timolol therapy is the amount of drug getting into systemic circulation that adversely affects vital organ functions in elderly patients.
