Formulations and methods for providing progestin-only contraception to a woman while minimizing various side effects, such as breakthrough bleeding, that are normally associated with progestin-only contraception are disclosed and described. In one aspect, the method can include transdermally administering a formulation having a contraceptively effective amount of a single progestin as the sole active hormonal agent to the woman as part of a contraceptive regimen.

The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and/or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder. In some aspects, the composition may be presented in the form of an unoccluded or free form topically administered gel.

The adhesive capability of matrix-type transdermal devices for the delivery of drugs, cosmetics, emollients and the like is altered by incorporating into the pressure-sensitive adhesive an effective amount of a polydiorganosiloxane polymer fluid adhesion adjusting agent. The properties of the pressure-sensitive adhesive are modified to enable a matrix-type patch to adhere temporarily to the skin for a period sufficient to accomplish its desired delivery purpose and then be removed without causing skin damage or irritation and without leaving substantial adhesive residue on the skin. Polydimethylsiloxanes (dimethicones) are preferred adhesion adjusting agents and acrylic-based polymers are preferred pressure-sensitive adhesives. Matrix-type patches containing anti-wrinkle agents formulated with dimethicones in the adhesive for application to areas on the face and particularly around the eyes are especially useful.

Transdermal delivery devices containing polydiorganosiloxane polymers to regulate adhesive properties

A method of making a pressure sensitive matrix patch for transdermal delivery of a drug is disclosed. The method includes the steps of dissolving a hydrophilic salt form of the drug in the water phase of an aqueous dispersion of a hydrophobic pressure sensitive adhesive, casting the resulting mixture as a thin film, and evaporating the water. The physical stability of the drug in the film is excellent, and crystallization of the drug is inhibited. A method of increasing the transdermal flux of an acidic drug is also disclosed.

An anti-wrinkle skin treating composition comprises a pressure sensitive matrix patch having dissolved in the adhesive a mixture of antioxidants in the form of a Vitamins C ester and Vitamin E. Also preferably dissolved in the adhesive are glycerine and a polydiorganosiloxane adhesion-adjusting agent. Optionally dissolved in the adhesive is also one or more members selected from the group consisting of moisturizing agents, skin collagen synthesis promoting agents and exfoliating agents. When applied to a wrinkled skin area the composition acts to diminish fine wrinkles and improves the overall thickness, elasticity, firmness and smoothness of the skin. The modified adhesive properties of the patch are sufficient to maintain the patch in place on the skin for the recommended treatment period while allowing the patch to be readily removed without causing skin irritation or leaving adhesive residue on the skin.
