The present invention generally relates to the transdermal delivery of various compounds. In some aspects, transdermal delivery may be facilitated by the use of a hostile biophysical environment. One set of embodiments provides a composition for topical delivery comprising a phosphodiesterase type 5 inhibitor and/or a salt thereof, and optionally, a hostile biophysical environment and/or a nitric oxide donor. In some cases, the composition may be stabilized using a combination of a stabilization polymer (such as xanthan gum, KELTROL® BT and/or KELTROL® RD), propylene glycol, and a polysorbate surfactant such as Polysorbate 20, which combination unexpectedly provides temperature stability to the composition, e.g., at elevated temperatures such as at least 40° C. (at least about 104° F.), as compared to compositions lacking one or more of these.

Treatment of erectile dysfunction and other indications

The present invention generally relates to the transdermal delivery of various compounds. In some aspects, transdermal delivery may be facilitated by the use of a hostile biophysical environment. One set of embodiments provides a composition for topical delivery comprising a phosphodiesterase type 5 inhibitor and/or a salt thereof, and optionally, a hostile biophysical environment and/or a nitric oxide donor. In some cases, the composition may be stabilized using a combination of a stabilization polymer (such as xanthan gum, KELTROL&#xae; BT and/or KELTROL&#xae; RD), propylene glycol, and a polysorbate surfactant such as Polysorbate 20, which combination unexpectedly provides temperature stability to the composition, e.g., at elevated temperatures such as at least 40&#xb0; C. (at least about 104&#xb0; F.), as compared to compositions lacking one or more of these.

The present invention generally relates to the transdermal delivery of various compositions. In some aspects, the transdermal delivery may be facilitated by the use of a hostile biophysical environment. One set of embodiments provides a composition for topical delivery comprising ibuprofen and/or an ibuprofen salt, a nitric oxide donor, and optionally, a hostile biophysical environment. In some cases, the composition may be stabilized using a stabilization polymer such as xanthan gum, KELTROL&#xae; BT and/or KELTROL&#xae; RD; propylene glycol; and a polysorbate surfactant such as Polysorbate 20, which unexpectedly provides temperature stability to the composition, e.g., at elevated temperatures such as at least 40&#xb0; C. (at least about 104&#xb0; F.), as compared to compositions lacking one or more of these.

Delivery of ibuprofen and other compounds

The present invention generally relates to the transdermal delivery of various compounds. In some aspects, transdermal delivery may be facilitated by the use of a hostile biophysical environment. One set of embodiments provides a composition for topical delivery comprising an Hantihistamine and/or a salt thereof, and optionally, a hostile biophysical environment and/or a nitric oxide donor. In some cases, the composition may be stabilized using a combination of a stabilization polymer (such as xanthan gum, KELTROL&#xae; BT and/or KELTROL&#xae; RD), propylene glycol, and a polysorbate surfactant such as Polysorbate 20, which combination unexpectedly provides temperature stability to the composition, e.g., at elevated temperatures such as at least 40&#xb0; C. (at least about 104&#xb0; F.), as compared to compositions lacking one or more of these.

Systems and methods for treatment of allergies and other indications

The present invention generally relates to the improvement of tissue health by increasing local blood flow. In some aspects of the invention, increased local blood flow is effected by the transdermal delivery of the nitric oxide precursor L-arginine and/or its derivatives alone, or optionally in conjunction with an adjunct such as theophylline. The transdermal delivery is effected, in certain embodiments through the means of a hostile biophysical environment, such as that created by a high ionic strength environment. Various pathological states caused by, or occurring in conjunction with, insufficient blood flow, can be treated using the systems and methods of the invention as described herein. In other embodiments, increased blood flow using the systems and methods of the invention may result in enhanced healing, for example, through greater availability of the constituents of the blood. Examples of conditions which may benefit from increased blood flow include, but are not limited to, erectile dysfunction, hair loss, female sexual dissatisfaction, sagging facial or other body tissue, peripheral vascular disease including claudication, neuropathy, skin ulcers, bone healing, wound healing, viral and bacterial infection, and skin grafting.
