Sustained drug delivery systems. I. The permeability of poly(ϵ‐caprolactone), poly(DL‐lactic acid), and their copolymers
Abstract
The maximum steady state flux, diffusion coefficients, and solubilities of five contraceptive steroids in homopolymers and copolymers of ϵ‐caprolactone and DL‐lactic acid were determined. The permeabilities of polymers of ϵ‐caprolactone were comparable to silicone rubber and, by inference, are suitable for the construction of drug delivery devices. Poly(DL‐lactic acid) was 10 4 times less permeable, although its permeability was significantly enhanced by additives.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
