Aqueous flow in human eyes is reduced by forskolin, a potent adenylate cyclase activator.


Forskolin, which lowers intraocular pressure in rabbits, monkeys, and human subjects, was tested for its effect on the rate of aqueous humor flow and on outflow facility. Topical sodium fluorescein was used to measure the rate of aqueous humor flow in forskolin or placebo treated eyes. Tonography was used to determine outflow facility before forskolin administration and at 3 hr after administration of the drug. In eight human subjects who showed reduction of intraocular pressure in response to a single drop of forskolin, flow was reduced by an average of 34%, compared to the contralateral eye during the same period of time. No significant change in outflow facility occurred. The action of forskolin in reducing intraocular pressure was the direct result of a reduction in net aqueous flow.
