Publication number: 20040265353Abstract: Systems and methods for attenuating a panic attack are provided. Such methods can comprise steps of delivering a drug to a subject such that the drug forms a depot beneath a skin surface, wherein the drug is suitable for attenuating a panic attack if delivered in a pharmaceutically effective amount into systemic circulation of the subject; and applying heat to the skin surface when the subject experiences an onset of the panic attack, thereby causing the pharmaceutically effective amount of the drug to rapidly enter systemic circulation from the depot.Type: ApplicationFiled: May 28, 2004Publication date: December 30, 2004Applicant: Zars, Inc.Inventors: Jie Zhang, Kevin S.

Patent number: 6756053Abstract: The present invention is directed to a method and system for delivering a drug into the systemic circulation. The method comprises establishing a drug depot in a patient's skin and/or sub-skin tissues by applying a transdermal drug delivery system on the patients skin, for a predetermined time so that a drug depot is formed in said user's skin and/or sub-skin tissues. A heating source is placed proximate to the skin area to rapidly release a bolus of the drug from the depot into the systemic circulation when there is a need to rapidly increase the drug's concentrations in the systemic circulation.Type: GrantFiled: June 11, 2001Date of Patent: June 29, 2004Assignee: Zars, Inc.Inventors: Jie Zhang, Wade Hull, Larry Rigby

Patent number: 6726673Abstract: The present invention relates to a method and apparatus for increasing the delivery rate of an androgen transdermal therapeutic system through the skin. An androgen transdermal therapeutic system can be applied to a patient's skin for delivery of the androgen. A temperature modification apparatus which is capable of generating controlled heat is applied approximate to the androgen transdermal therapeutic system. The heating from the temperature modification apparatus raises the temperature of the androgen transdermal therapeutic system and raises the temperature of the patient's skin to achieve an increased rate of delivery of androgen through the skin. The controlled heat can also be used to adjust dosage rates of the androgen transdermal therapeutic system and to mimic natural circadian patterns. The controlled heating may also be used to improve or regulate the release of androgen from injected/implanted extended/controlled release systems.Type: GrantFiled: May 24, 1999Date of Patent: April 27, 2004Assignee: Zars, Inc.Inventors: Jie Zhang, Hao Zhang, Wade A.

Patent number: 6528086Abstract: This invention relates to an apparatus and method of drug delivery on a human body surface. The formulation comprises a drug, a conversion agent capable of converting the formulation from a less solid phase to a coherent, soft, solid phase, and a vehicle medium or carrier for the drug and conversion agent. The drug formulation is applied to this human body surface in its less than solid phase and is subsequently converted to a soft solid phase while the drug is being delivered through the human body surface. After delivery of the drug is complete, the soft solid formulation can be removed or peeled from the body surface as a coherent solid formulation. The drug formulation provides control over drug delivery rates and allows the formulation to be removed without leaving a messy, residual formulation on the body surface.Type: GrantFiled: September 28, 1999Date of Patent: March 4, 2003Assignee: Zars, Inc.Inventor: Jie Zhang
