The Therapeutic System: Therapeutic Implications of Rate-Controlled Drug Delivery

  • John Urquhart
Part of the Experimental Biology and Medicine book series (EBAM, volume 7)


The concept of the therapeutic system (Anonymous, 1970, 1971; Heilmann, 1982) brought Tak Higuchi and Alex Zaffaroni together in a day-to-day working collaboration that continued for over 4 years between 1969 and 1972. Higuchi’s laboratory played a major role in developing the first two therapeutic system products, which have embodied a number of pharmaceutical “firsts”. These are the pilocarpine ocular therapeutic system and the progesterone uterine therapeutic system.
