Development Of The Sustained Release Analgesic Formulations For Rodents And A Novel In Vitro Model For Parenteral Formulations With The Character Of A Level A Ivivc, Jin Xu

Theses and Dissertations (ETD)

Laboratory animals are often subjected to various painful surgical procedures such as laparotomy, thoracotomy or orthopedic procedures as well as non-surgical procedures such as the induction of arthritis. Any procedure that causes pain in humans is assumed to cause pain in animals too. It is the ethical obligation of all research personnel to reduce or preferably eliminate pain and distress by using analgesics. Furthermore, the Institutional Animal Care and Use Committee (IACUC) requires that appropriate anesthetics and/or analgesics must be used to minimize or eliminate pain and distress for animals undergoing painful procedures.

The oral administration route is the most …

In Vitro Methods To Predict Aerosol Drug Deposition In Normal Adults, Renishkumar Delvadia

Theses and Dissertations

This research was aimed at the development and validation of new in vitro methods capable of predicting in vivo drug deposition from dry powder inhalers, DPIs, in lung-normal human adults. Three physical models of the mouth, throat and upper airways, MT-TB, were designed and validated using the anatomical literature. Small, medium and large versions were constructed to cover approximately 95% of the variation seen in normal adult humans of both genders. The models were housed in an artificial thorax and used for in vitro testing of drug deposition from Budelin Novolizer DPIs using a breath simulator to mimic inhalation profiles …
