title: Drug permeation through membranes V: interaction of diazepam with common excipients.
abstract: The effects of common tablet excipients on the permeation of diazepam through polydimethylsiloxane membranes and on the turnover time of goldfish were studied. The permeability coefficient decreased and the turnover time increased in the presence of talc, polysorbate 80, and, possibly, fumed silicon dioxide, but these parameters were unaffected by lactose, microcrystalline cellulose, and starch.
