Key facts

Disease & market context

Drug Delivery Technology (Multi-Therapeutic)

$3.5B Global Drug Delivery Market (2001)

Disease Overview

ALZA Corporation pioneered osmotic and transdermal drug delivery systems. Their OROS technology enabled once-daily dosing of existing molecules, creating billions in value through improved patient compliance. At acquisition, ALZA's technologies were embedded in over 30 marketed products across multiple therapeutic areas.

Deal Context

J&J's $10.5B acquisition gave it control of OROS (osmotic delivery) and D-TRANS (transdermal) platforms. Concerta (OROS methylphenidate) for ADHD and Ditropan XL (oxybutynin) for overactive bladder were immediate revenue generators. The platform approach enabled J&J to reformulate existing drugs across its Janssen portfolio.
