摘要:
A drug dosage form is provided in the form of a solid tablet which is greater than 50% by weight the local anesthetic agent. The local anesthetic agent may be selected from the group consisting of an aminoamide, an aminoester, and a combination thereof. The drug tablet may be in the form of a mini-tablet which is greater than 70 wt % drug, with the balance being excipient. For example, the anesethetic agent may include lidocaine, in a salt or base form, combined with binder and lubricant excipients. Implantable drug delivery devices including the tablets are also provided, e.g., one or more of the drug tablets may be contained in a biocompatible housing. The drug tablets may be substantially cylindrical with flat end faces, and the device may have from 10 to 100 drug tablets aligned in the housing with the flat end faces of adjacent tablets abutting one another.

Implantable medical devices and treatment methods are provided, particularly for use in the bladder. The device is configured for retention in the bladder for at least a portion of the drug delivery period and includes at least one biodegradable component such that following a biodegradation at a selected time, the retention function is lost and the device or portions thereof are resorbed and/or excreted. The method may include deploying into the bladder of a patient a device having a device structure housing a drug formulation comprising at a drug; releasing drug from the device structure into the bladder; and then, changing the composition of urine in the bladder, e.g., by altering the pH, to trigger degradation of at least part of the device structure to enable the device structure or parts thereof to be excreted from the bladder.
摘要:
A drug delivery device is provided that includes a device body, a number of solid, compressed drug tablets, and a retention frame. The device body includes a drug reservoir lumen and a retention frame lumen. The number of solid, compressed drug tablets are positioned in the drug reservoir lumen, and the retention frame is positioned in the retention frame lumen. The drug tablets may be mini-tablets aligned in the drug reservoir lumen, with an interstice formed between any two adjacent drug tablets facilitating deformation of the device body. Systems and method are also provided for loading a drug delivery device. In one embodiment, the method includes positioning one or more solid drug units upstream of the drug delivery device; and driving the drug units into the drug delivery device with a flow of pressurized gas.

Implantable devices and methods for delivery of lidocaine or other drugs to a patient are provided. In one embodiment, the device includes a first drug portion which has a first drug housing which contains a first drug formulation in a solid form which includes a pharmaceutically acceptable salt of lidocaine; and a second drug portion which includes a second drug housing which contains a second drug formulation which includes lidocaine base. In another embodiment, the device includes a drug reservoir component which has an elastic tube having at least one lumen bounded by a porous sidewall having an open-cell structure, a closed-cell structure, or a combination thereof; and a drug formulation contained within the at least one lumen, wherein the device is deformable between a low-profile deployment shape and a relatively expanded retention shape.
