Drug transport composition to improve steroid stability |
| abstract |
A stabilized patch device for transdermal transport of a steroid drug comprising a 3-keto-4-en functional group is described above, wherein the patch consists of a carrier free of acid functional groups and an effective amount of the steroid drug. The device further includes adhesion as a penetration enhancer or excipient and such adhesive layers do not include acid functional groups. The device is a matrix patch or a liquid reservoir patch, in which case the carrier is a biocompatible polymeric adhesive layer in which the steroid drug is initially mixed. The adhesive layer is suitably an acrylic polymer or copolymer. In liquid reservoir patches the carrier is a controlled viscous composition comprising a diluent or thickener. Suitable steroid drugs include certain corticosteroids and sex hormones such as progesterone and androgens. The method of stabilizing such steroid drugs upon storage has been described in detail. |
