559 results about "Intrathecal" patented technology

Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF) and is useful in spinal anesthesia, chemotherapy, or pain management applications. This route is also used to introduce drugs that fight certain infections, particularly post-neurosurgical. The drug needs to be given this way to avoid being stopped by the blood brain barrier. The same drug given orally must enter the blood stream and may not be able to pass out and into the brain. Drugs given by the intrathecal route often have to be compounded specially by a pharmacist or technician because they cannot contain any preservative or other potentially harmful inactive ingredients that are sometimes found in standard injectable drug preparations.

Rapid acting drug delivery compositions

Drug formulations for systemic drug delivery with improved stability and rapid onset of action are described herein. The formulations may be administered via buccal administration, sublingual administration, pulmonary delivery, nasal administration, subcutaneous administration, rectal administration, vaginal administration, or ocular administration. In the preferred embodiments, the formulations are administered sublingually or via subcutaneous injection. The formulations contain an active agent and one or more excipients, selected to increase the rate of dissolution. In the preferred embodiment, the drug is insulin, and the excipients include a metal chelator such as EDTA and an acid such as citric acid. Following administration, these formulations are rapidly absorbed by the oral mucosa when administered sublingually and are rapidly absorbed into the blood stream when administered by subcutaneous injection. In one embodiment, the composition is in the form of a dry powder. In another embodiment, the composition is in the form of a film, wafer, lozenge, capsule, or tablet. In a third embodiment, a dry powdered insulin is mixed with a diluent containing a pharmaceutically acceptable carrier, such as water or saline, a metal chelator such as EDTA and an acid such as citric acid. Devices for storing and mixing these formulations are also described.
