Abstract: Provided is a novel barrier membrane and a method using the barrier membrane for testing the transdermal penetration behavior of a bioactive agent. The method employs shed snake skin as the model barrier membrane. In particular, the method comprises the steps of providing a dose of a donor formulation containing the bioactive agent, and a receptor solution, with a barrier membrane of shed snake skin separating the donor formulation and receptor solution. The receptor solution is then serially sampled and assayed in order to determine the concentration of the bioactive agent in the receptor solution. The use of the shed snake skin has been found to provide reproducible and uniform results as a model barrier membrane. As well, the shed snake skin offers the advantages of being readily available and storable for an extended period of time.

Abstract: A chemiluminescence method for assaying compounds containing primary amino groups using 1-cyano-2-substituted benz(f)- or naphth(f)-isoindole fluorescers is disclosed. The 1-cyano-2-substituted benz(f)- or naphth(f)-isoindole (CBI or CNI) is formed by reacting a compound containing a primary amino group with naphthalene-2-3-dicarboxaldehyde or anthracene-2,3-dicarboxaldehyde in the presence of cyanide ion. The reaction product of hydrogen peroxide with an oxalate ester is then combined with the CBI or CNI to form an analyte which exhibits chemiluminescence. A detector is used to measure the chemiluminescence emission from the chemiluminescence derivatized analytes. Compounds containing primary amino groups which may be assayed according to the present invention include primary amines, amino acids, peptides and catecholamines. The method can also be adapted to the analysis of trace amounts of cyanide ion and hydrogen peroxide.

Abstract: An osmotic drug (or other beneficial substance) delivery system comprises a multi-chamber compartment formed by an external shell and one or more chamber-dividing walls each with a small orifice, of a microporous material and overlayers of semipermeable membranes completely covering the outer shell of all but one chamber and substantially covering the outer shell of the remaining chamber. Osmotic agents, adjuvants, enzymes, drugs, pro-drugs, pesticides and the like are incorporated in the chambers covered by the semipermeable membrane, and external fluids that diffuse into those chambers form solutions and by osmotic pressure are forced through the orifice to the drug chamber to form a solution thereof and then through the exposed microporous shell to the exterior of the device at a rate controlled by the permeability of the semipermeable overlay and the osmotic pressure gradient across the shell.
