Abstract

Drug delivery devices and methods are provided for delivering one or more drugs into a biological tissue. The devices include microneedles that may be separable from the drug delivery devices, control drug release rate and/or direction, or a combination thereof. When the microneedles are separable, a force applied to the drug delivery devices may be effective to penetrate a biological tissue with the microneedles and then to separate the microneedles from the drug delivery devices. The drug delivery devices may be capable of achieving discrete periods of drug release. Methods for delivery drug with microneedles also are provided.
