A long-lasting, controlled-release local anesthetic liposome preparation is produced by: providing a liposome composition, which is obtained by mixing, in a water-miscible organic solvent, a first aqueous phase solution with a water-miscible organic solution, in which a phospholipid and cholesterol are contained at a defined total concentration, at a defined ratio by volume thereby obtaining an emulsion wherein a total concentration of the phospholipid and cholesterol in the mixed phase is at 15 w/v % to 50 w/v %, followed by subjecting the emulsion to external solution exchange with a second aqueous phase solution to obtain a liposome composition wherein an ion gradient is formed between an internal-region aqueous phase of a liposome membrane made of the first aqueous phase solution and an external-region aqueous phase of the liposome membrane made of the second aqueous phase solution; and encapsulating a local anesthetic in the internal-region aqueous phase according to a remote loading method.

The present invention relates to novel anesthetic compositions containing a non-polymeric carrier material and an anesthetic, where the compositions are suitable for providing a sustained local anesthesia without an initial burst and having a duration for about 24 hours or longer. Certain compositions are also provided that include a first anesthetic and a second anesthetic. In such compositions, the second anesthetic is a solvent for the first anesthetic and provides an initial anesthetic effect upon administration to a subject. The non-polymeric carrier may optionally be a high viscosity liquid carrier material such as a suitable sugar ester. The compositions can further include one or more additional ingredients including active and inactive materials. Methods of using the compositions of the invention to produce a sustained anesthetic effect at a site in a subject are also provided.

The present invention provides sustained release formulations comprising one or more active pharmaceutical ingredient(s); at least one biocompatible polymer excipient; and at least one biocompatible solvent; methods for preparing the sustained release formulations, and methods for treating localized pain in a subject in need thereof.

Methods, agents, and devices to treat medical conditions through local chemical neuromodulation of the autonomic nervous system are described. Drug formulations may be injected at or near ganglia, nerve plexi, ganglionated plexi, and nerves to treat different diseases. Target sites for the treatment of cardiac and other disease conditions may include extrinsic stellate (cervicothoracic) and cervical ganglia of the sympathetic chain, and intrinsic cardiac nerves and ganglionated plexi innervating the myocardium.

The present invention relates to tetracaine based anesthetic formulations and methods of use thereof The invention further relates to topical formulations of tetracaine and methods of topically anesthetizing body tissues. The present invention also relates to tetracaine based dental anesthetic formulations and methods for anesthetizing the maxillary dental arch using these formulations.

The invention relates to substituted pyridine compounds of Formula I: (I) or a pharmaceutically acceptable salt, prodrug, or solvate thereof, wherein A.sup.1, X, A.sup.2, R.sup.1a, R.sup.1b, R.sup.1c, G, and z are defined as set forth in the specification. The invention is also directed to the use of compounds of Formula I to treat a disorder responsive to the blockade of sodium channels. Compounds of the present invention are especially useful for treating pain. ##STR00001##

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.
