Zengen’s New Technology First To Deliver Drug Active Ingredients in New Chloraseptic® Relief Strips(tm)


Advancement To Revolutionize Oral Drug Delivery

Zengen, Inc. announced today that its revolutionary drug delivery technology will be used in the new Chloraseptic® Relief Strips(tm), the only medicated oral strip for the treatment of sore throat. Zengen’s proprietary technology is the first to use drug active ingredients in an oral strip.

"We are excited to be part of the new generation of Chloraseptic products," said R. Steven Davidson, chief executive officer of Zengen. "Our technology holds promise to revolutionize the drug delivery industry because it marks the first time that drug active ingredients have been delivered utilizing an oral strip. This method is effective and convenient for consumers and may be more cost efficient for manufacturers."

The medicated oral strip is structured as a proprietary bilayer system. This system eliminates the use of irritating solvents and reduces damage due to heat and moisture, maintaining the integrity and efficacy of the active ingredients.

Certain auxiliary compounds used with the bilayer system can assist with rate of dissolution, water solubility, mucous adhesion and coating on the exterior film layer. For instance, depending on the auxiliary compounds used, Zengen’s oral strips can be manufactured to dissolve quickly or over an extended period of time, regulating the release of active material.

Previous technologies have proven too harsh, exposing the medical compound to extreme heat, moisture, compromising solvents and other irritants. With the creation of Chloraseptic Relief Strips, Zengen has established a new process which prevents the exposure to these harmful irritants and incorporates additional compounds to make the strips more suitable for various drug delivery needs.

"Chloraseptic Relief Strips bring true innovation to the cough/cold category and are a fitting extension of the Chloraseptic product line," said Elise Donahue, president and chief operating officer of Prestige Brands International. "Zengen’s technology has allowed us to make our product more convenient, accessible and modern for our consumers."

About Chloraseptic Relief Strips

New Chloraseptic Relief Strips are the first and only product of its kind to provide immediate and convenient relief of sore throat pain in an oral strip. The oral strips contain the active ingredients benzocaine and menthol. Chloraseptic Relief Strips will be available in major retail markets and drug stores beginning in September, 2003. The strips will be sold in two 20-count packs at a suggested retail price of $5.29.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
