Melt-extruded orally administrable opioid formulations

Bioavailable sustained release oral opioid analgesic dosage forms, comprising a plurality of multiparticulates produced via melt extrusion techniques disclosed.

A transdermal patch useful for evaluating the therapeutic effectiveness of a transdermally delivered medicinal agent is disclosed. The patch includes a substantially impermeable backing layer, a delivery layer containing a medicament and a substantially impermeable blocking layer. The delivery layer is arranged between the backing and blocking layers to prevent the release of the medicament contents from the delivery layer when the transdermal patch is affixed to the skin of a mammal. In alternative embodiments, non-transdermal placebo systems such as oral dosage forms which are coated with substantially impermeable layers to create virtually identical placebos of active oral delivery systems such as tablets, capsules and osmotic tablets are disclosed. Methods of comparing the therapeutic effectiveness of active dosage forms, i.e. transdermal units containing a medicament to placebo or to comparable active agents in either similar or different delivery systems are also disclosed.
