摘要:
The present invention comprises non occlusive compositions for transdermal delivery of nicotine, and more particularly pharmaceutically acceptable salts thereof, and methods of making same. The composition may, for example, be a gel suitable for transdermal or transmucosal applications. The compositions of the present invention typically comprise a mixture of water and alcohol, and a solvent system having a mono alkyl ether of diethylene glycol and a glycol present in specified ratios and in specific amounts, wherein the pH of the gel is usually between a pH of 5.5 and 7. The compositions may include further components, for example, the hydroalcoholic vehicle may further comprise additional penetration enhancer(s), buffering agent(s), antioxidant(s), stabilizer(s) and/or gelling agent(s). The invention also relates to a method for the sustained delivery of nicotine pharmaceutically acceptable salts to treat a variety of conditions and disorders.
摘要:
This invention relates to novel transdermal or transmucosal pharmaceutical formulation which reduces the occurrences of contamination of other individuals and the transference to clothing of the user. The novel formulation includes at least one pharmacologically active ingredient, and a solvent system having a monoalkylether of diethylene glycol and a glycol present in specified ratios, and a mixture of water and alcohol. The invention also relates to a method for inhibiting or delaying crystallization of an active agent in a pharmaceutical formulation.
摘要:
The invention relates to a dermal flowable-composition dispenser that includes a body for retaining a supply of the composition, an application portion having an application surface, and a conduit connecting the supply chamber with the application surface for facilitating the reproducible delivery of a predetermined dose of the composition to the application surface. The application surface includes a concave application surface and a front side having an upper rim enclosing the application surface and forming a depression that has a volume that is greater than or equal to the volume of the predetermine dose. Also, the application surface is configured and dimensioned such it can receive the patient's skin to allow for removal of the predetermined dose of the composition, and wherein the concave application surface is shaped such that the entire application surface contacts the patient's skin when the application surface is pressed thereagainst.
摘要:
The invention relates to the use of chemical fragrance ingredient to lower the melting point of active agents, thereby changing crystalline active agents into an amorphous state. The invention also relates to methods of enhancing the transdermal or transmucosal skin permeation or skin penetration of pharmacologically active agents to patients in need thereof. The compositions of the present invention present the additional benefits of being substantially alcohol-free and having a pleasant olfactory profile.
摘要:
A formulation, method and system for the topical, transdermal or transmucosal administration of a therapeutically effective active agent. Particularly, the invention provides a formulation, system and method for enhancing the permeation or penetration of active agents across the dermal or mucosal surfaces of a mammalian subject. The formulation includes a plant extract of the genus Curcuma of the family Zingiberaceae, a germacrone, or a natural or synthetic constituent thereof, which has been found to increase penetration of the active agent across the dermal or mucosal surface. If desired, a secondary permeation enhancer of a polyalcohol, a monoalkyl ether of diethylene glycol, a tetraglycol, or a mixture thereof can be used for certain active agents for optimal permeation enhancement.
摘要:
A formulation for transdermal or transmucosal administration of an active agent. The formulation includes an active agent and a delivery vehicle comprising a C2 to C4 alkanol, a polyalcohol, and a permeation enhancer of monoalkyl ether of diethylene glycol present in an amount sufficient to provide permeation enhancement of the active agent through dermal or mucosal surfaces. The formulation is substantially free of long-chain fatty alcohols, long-chain fatty acids, and long-chain fatty esters in order to avoid undesirable odor and irritation effects caused by such compounds during use of the formulation. Also, the active agent is testosterone that is present in an amount of about 1%, the alkanol is ethanol that is present in an amount of about 46.28% to about 47.5% of the formulation; the polyalcohol is propylene glycol that is present in an amount of about 6% of the formulation; and the permeation enhancer is diethylene glycol monoethyl ether that is present in an amount of about 5% of the formulation.
摘要:
A transdermal or topical composition including anticholinergic agents, such as oxybutynin, a urea-containing compound and a carrier system. A method is disclosed for treating a subject for urinary incontinence while reducing the incidences of peak concentrations of drug and undesirable side effects.
摘要:
The present invention relates generally to formulations for transdermal or transmucosal administration of an active agent such as estradiol. The invention is a substantially malodorous-free and irritation free transdermal formulation which is substantially free of long chain fatty alcohols, long-chain fatty acids, and long-chain fatty esters.
