Abstract

A transdermal patch having caffeine as an active ingredient in an amount sufficient to raise the awareness level of the user. The patch may be in the form of a hydrogel patch or may be a multi-layer structure. The patch may also comprise an acrylated copolymer, mineral oil, sodium hydroxide, menthol or water.

Description

<p>TRANSDERMAL PATCH</p>
<p>Field of Invention</p>
<p>This invention relates to transdermal patches which may be applied to the skin of a human subject and are loaded with an active ingredient which is intended to pass across the skin into the user's bloodstream to provide a medical or other effect.</p>
<p>Background to the Invention</p>
<p>Transdermal patches are known containing nicotine and which are intended to assist the user to give up smoking.</p>
<p>US 2003152612-A discloses a multi-layer, flexible patch in which the active ingredient can be any one of a number of chemical compounds, including caffeine, and for use in reducing the incidence of human cellulite.</p>
<p>Statement of the Invention</p>
<p>According to the present invention there is provided a transdermal patch having caffeine as an active ingredient in an amount sufficient to raise the awareness level of the user.</p>
<p>Preferably the patch is a hydrogel patch, more preferably a TDDS hydrogel patch.</p>
<p>Preferably the caffeine is present in the patch in an amount of from 50 -500 mg. More preferably 100 -350 mg, most preferably 150 to 250 mg so that for instance the patch may contain about 200 mg caffeine.</p>
<p>Preferably the patch is substantially rectangular and with a surface area of from 5 -20 cm2, more preferably about 10 cm.</p>
<p>Preferably the patch further contains one or more of acrylated copolymer, mineral oil, sodium hydroxide, Polysorbate 60 and menthol.</p>
<p>Preferably the patch includes a layer holding a water-based composition including the caffeine.</p>
<p>Preferably the patch is a multi-layer structure, a first layer being a fabric layer and including the active ingredient and a second layer being a backing layer attached to said first layer. More preferable the first and second layers have adjacent adhesive surfaces.</p>
<p>The present invention also provides a transdermal patch containing caffeine as an active ingredient for use in raising the level of awareness of a human subject.</p>
<p>Furthermore, the invention provides a method of raising the awareness of a human subject comprising applying to the body of the subject a transdermal patch containing, as an active ingredient, caffeine.</p>
<p>Detailed Description of the Invention</p>
<p>Caffeine patches, having a surface are of about 10 cm2, and containing about 200mg caffeine, and also containing amounts of acrylated copolymer, mineral oil, sodium hydroxide, Polysorbate 60 and menthol, as well as water, were applied to the upper arms of about 50 test subjects. The subjects were mainly in the 16-30 age group and each was supplied with one to six patches. The subjects reported their experiences by means of responses on a questionnaire.</p>
<p>Most of the subjects reported an on average higher and longer-lasting stimulation than one of the commercially available energy drinks or one cup of coffee. Furthermore most subjects reported a significant boost in their energy level. Many subjects reported that the use on a patch cancelled out alcohol-induced sleepiness.</p>
<p>Patches in accordance with the present invention can be used in many situations,</p>
<p>example being,-</p>
<p>* late night driving to avoid microsleep * staying awake during meetings and classes * during sporting activities, especially competitions * "burning midnight oil", such as essay writing or work assignments * reaching a higher energy level during examinations and a night out Caffeine patches according to the present invention may have a multi-layered or matrix structure that allows for constant delivery speed of the active ingredient. This enables a higher dose to be used while avoiding an over-stimulation of the sympathetic nervous system.</p>
<p>The present invention may also have application in overcoming a subject's addiction to caffeine taken in one of the conventional ways, for instance in drinks of coffee, tea or other food stuffs.</p>
