invention of levonorgestrel

LidoSite uses an active transdermal delivery technology known as iontophoresis,which administers medications through the skin via a mild electric current invention of levonorgestrel. The LidoSite system administers lidocaine and epinepherine using a patentedelectrotransport technology that enables the controlled delivery of medicationover a predetermined period of time, from minutes to days invention of levonorgestrel. Topical anestheticcreams and patches can take up to an hour to numb the skin, while LidoSite worksin 10 minutes invention of levonorgestrel. This product has successfully completed clinical trials and hasbeen found to significantly decrease pain from needle injections and similarprocedures in both adults and children invention of levonorgestrel. Lidosite is intended to also addressa strong need in adult applications invention of levonorgestrel. Its major impact is expected to be in thepediatric population, where pain associated with needlesticks, blood-draw proceduresand immunizations is a major issue for the clinician, child and parent.

Studies Demonstrate Safety and Efficacy
More than 1,000 adults and children (ages 5 to 17 years) participated in clinicalstudies evaluating the safety and efficacy of the Vyteris system in providingtopical anesthesia invention of levonorgestrel. Two pivotal studies compared the system (administering lidocaine10% and epinephrine 0.1%) with placebo for use prior to needle injections orintravenous (IV) insertions invention of levonorgestrel. Additional studies evaluated the efficacy of thesystem for use prior to the removal of surface skin lesions (via incision orlaser treatment) invention of levonorgestrel. Patients treated with Vyteris' LidoSite system experiencedsignificantly less pain associated with needlestick procedures compared withsubjects treated with the placebo system invention of levonorgestrel. Consequently, fewer patients in theactive group reported experiencing severe pain and most reported feeling littleor no pain in contrast to patients in the placebo group invention of levonorgestrel. In these studies, thepatients were evaluated using established pain assessment tools including theFacial Affective Scale (FAS) (A = no pain, I = maximal pain) or the Visual AnalogueScale (VAS) (0 = no pain, 10 = maximal pain) methods invention of levonorgestrel. Evaluations were takenimmediately following patch removal and at 24 hours for side effects invention of levonorgestrel. Pain scoreevaluations from both scales resulted in statistically significantly less painfor those who used the Vyteris' LidoSite system, as compared to placebo invention of levonorgestrel. Inthese studies, the most common side effect was mild erythema (skin redness),which disappeared for most patients within 24-hours.
