Biosynchronous transdermal drug delivery
First Claim
1. A method for delivering a bioactive agent to a human or animal comprising:
- (a) providing a transdermal drug delivery device coupled to the human or animal, the transdermal drug delivery device comprising;
(i) a drug reservoir comprising the bioactive agent,(ii) a membrane in contact with the skin of the human or animal;
(iii) an electronic programmable timing mechanism;
(iv) a mechanism for causing the bioactive agent to be delivered from the drug reservoir to the membrane in response to the timing mechanism, the bioactive agent being delivered transdermally by passive diffusion from the membrane into the skin of the human or animal; and
(v) an expandable waste reservoir for controlled discontinuance of the delivery of the bioactive agent;
(b) providing timing routines implemented by the timing mechanism, wherein the timing routines are selected to deliver the bioactive agent at a time, rate, sequence and/or cycle that is synchronized with a biological rhythm of the human or animal;
(c) delivering the bioactive agent from the drug reservoir to the membrane in response to the timing mechanism;
(d) transdermally delivering the bioactive agent from the membrane into the skin of the human or animal by passive diffusion; and
(e) removing the bioactive agent and/or a carrier solution from the membrane via the expandable waste reservoir to discontinue delivery of the bioactive agent to the human or animal;
wherein the device is maintained in contact with the skin during removal of the bioactive agent and/or carrier solution via the expandable waste reservoir.

Abstract
Systems and methods for treating diseases, addictions and disorders in humans and animals involving synchronizing and tailoring the administration of drug compounds with the body'"'"'s natural circadian rhythms, in order to counteract symptoms when they are likely to be at their worst. Automated and pre programmable transdermal drug administration system are used. This system can also utilize a pump or pressurized reservoir, and/or a system for removing depleted carrier solution, or other modulated dispensing actuator, in conjunction with micro-fabricated structures commonly referred to as Micro-needles, or heat, or iontophoresis, sonophoresis, or a wide range of chemical permeation enhancers.

7. A method for delivering a drug to a human or animal comprising:
-
(a) providing a transdermal drug delivery device comprising; (i) a source of the drug; (ii) a membrane in contact with the skin of the human or animal; (iii) an electronic programmable timing mechanism; (iv) a mechanism for causing the drug to be delivered from the source to the membrane in response to the timing mechanism, the drug being delivered transdermally by passive diffusion from the membrane into the skin of the human or animal; (v) a solvent removal system comprising an expandable waste reservoir for removing carrier solution and/or remaining drug; (b) providing timing routines implemented by the timing mechanism, wherein the timing routines are selected to deliver the drug at a time when the human or animal is expected to be asleep; (c) delivering the drug from the source to the membrane in response to the timing mechanism; (d) transdermally delivering the drug from the membrane into the skin of the human or animal by passive diffusion; and (e) removing carrier solution and/or remaining drug from the membrane via the expandable waste reservoir to discontinue delivery of the drug to the human or animal; and wherein the device is maintained in contact with the skin during removal of the carrier solution and/or remaining drug via the expandable waste reservoir. - View Dependent Claims (8, 9, 10)
