The invention relates to formulations for the electrically assisted transdermal delivery of lidocaine and epinephrine. The present invention further provides methods and devices for the electrically assisted delivery of local anesthetics, preferably lidocaine.

Formulation for electrically assisted delivery of lidocaine and epinephrine

A transdermal electrotransport drug delivery device having an anode, a cathode and a source of electrical power electrically connected to the anode and the cathode. The cathode includes a cathodic electrode and a cathodic reservoir comprised of a housing composed of a polymeric material and an aqueous medium in contact with the housing. The aqueous medium includes i) a drug or an electrolyte salt or a mixture thereof and ii) a cetylpyridinium salt in an amount sufficient to inhibit microbial growth in the aqueous medium. The polymeric material is compatible with the cetylpyridinium salt. A process is also provided wherein when electric current flows from the source of electrical power so that the drug is transdermally delivered to the patient by electrotransport from the anodic reservoir, the cetylpyridinium salt is not transdermally delivered to the patient by electrotransport from the cathodic reservoir. A process for preparing a transdermal electrotransport drug delivery device is also provided.

Transdermal electrotransport delivery device including a cathodic reservoir containing a compatible antimicrobial agent

A process for delivering a biocide to a container comprising admitting a biocide delivery device through an exit port of a urine container where the device is sized for passage through the exit port is disclosed.

Process for controlling pathogens in container

The invention disclosed and claimed an apparatus that relates to a delivery system comprising a biocide, with the delivery system designed and shaped for passages through the exit port of a urine container into the container. The invention disclosed and claim pertains also to a method of preventing infection in a patient by using the apparatus connected to a patient through a catheter.

Antipathogen assembly

An apparatus is disclosed comprising in combination (1) a container for receiving a fluid, and having an exit port, and (2) a delivery system designed for passage through the exit port into the container for releasing a biocide inside the container.

Biocide dispensing device for use in container

The invention pertains to a delivery system comprising a biocide, with the delivery system designed and shaped for passage through the exit port of a urine container into the container.
