| abstract |
The invention relates to the transdermal application of oligopeptides for reducing synaptic transmission in tissues of an animal. In one aspect, this invention relates to compositions comprising an oligopeptide and optionally a carrier comprising a positively charged “backbone” having positively charged branching or “efficiency” groups, as described herein. Most preferably the positively charged carrier is a long-chain positively charged polypeptide or a positively charged nonpeptidyl polymer, for example, a polyalkyleneimine. The invention further relates methods for producing a biologic effect of reducing synaptic transmission in a tissue by topically applying an effective amount of such a composition, preferably to the skin, of a subject or patient in need of such treatment. This invention also provides kits for preparing or formulating a composition that comprises the oligopeptide and optionally a carrier, as well as such additional items that are needed to produce a usable formulation, or a premix that may in turn be used to produce such a formulation. |
