The present invention is directed to a formulation for the delivery of hydrophobic active agents to a fluid environment of use while avoiding aggregation of the hydrophobic agents in the environment, the formulation comprising a hydrophobic active agent in an amount of 50 wt% (percent by weight) or greater together with polyoxyethylene 40 stearate and a disintegrant. The present invention is also directed to an improvement in a fluid-activated delivery device (10) wherein the delivery device includes a housing (12) defining an internal compartment (14), an active agent formulation (15) in the compartment, exit means (13) in the housing (12) for delivering the active agent formulation (15) from the delivery device, a fluid-activated expandable driving member (16) in the compartment, optionally a partition layer between the active agent formulation (15) and the driving member (16), and optionally a lubricant subcoat (18); wherein the improvement comprises an active agent formulation (15) comprising a hydrophobic active agent in an amount of 50 wt% (percent by weight) or greater together with polyoxyethylene 40 stearate and a disintegrant. |
