Anesthetic, Topical Patents (Class 514/817)
  • Patent number: 5667799
    Abstract: Methods are provided for the treatment of a host suffering from head ache pain with topical applications of a local anesthetic. The topical local anesthetic composition comprises an effective amount of a local anesthetic in combination with eucalyptol as a penetration enhancing agent, and optionally an additional penetration enhancing agent. The topical local anesthetic composition is applied to a keratinized skin site proximal to target nerves associated with the headache pain, usually to the supraorbital or occipital regions of the head. Upon application of the topical composition, the local anesthetic rapidly penetrates the skin to block conduction in the target nerves and provide pain relief to the host.

  • Patent number: 5593661
    Abstract: The composition of the present invention combines the local anaesthetic lidocaine in free base form and the non-CFC aerosol propellant HFC-134a(1,1,1,2-tetrafluoroethane; CF.sub.3 CH.sub.2 F) or HFC-227 (1,1,1,2,3,3,3-Heptafluoropropane; (CF.sub.3 CHFCF.sub.3), or a combination thereof, thus incorporating previously-unattainable amounts of the lidocaine free base in solution in a non-CFC aerosol propellant. This particular form of relatively-concentrated cosolvent-free anaesthetic permits improved inhalation delivery to the airway and lung, and topical airway local anaesthesia is thus readily provided. A method in accordance with the invention provides for release of the anaesthetic in aerosolized form of selected dosage from a canister containing the pressurized local anaesthetic composition into a patient's respiratory system directly or by way of an airway.

  • Patent number: 5589180
    Abstract: Methods and compositions are offered for reducing nerve injury pain associated with shingles (herpes-zoster and post-herpetic neuralgia), where intradermal delivery of lidocaine is maintained for a predetermined period of time. The lidocaine appears to specifically affect the damaged nerve fibers, while leaving the undamaged and normal nerve fibers with retention of response to other stimuli. Lidocaine formulations are provided which allow for the necessary dosage of the lidocaine in the dermis during the period of treatment. The formulation may be covered with an occlusive or non-occlusive dressing, which protects the lidocaine formulation from mechanical removal and enhances the transport of the lidocaine into the dermis. Long term relief is realized after maintenance of the administration of lidocaine has been terminated.

  • Patent number: 4695576
    Abstract: The local anesthetic, L-N-n-propylpipecolic acid-2,6-xylidide, namely: ##STR1## This compound is prepared by chlorinating L-pipecolic acid to yield the acid chloride, namely L-pipecolic acid chloride. The acid chloride is then reacted with 2,6-xylidine to yield L-pipecolic acid-2,6-xylidide. The L-N-pipecolic acid-2,6-xylidide is then propylated to yield the L-N-n-propylpipecolic acid-2,6-xylidide, which is a potent local anesthetic for humans and is of relatively low toxicity.

  • Patent number: 4659714
    Abstract: Improved methods of anesthesia for mammals, especially humans, are provided wherein the prolonging effect upon local anesthesia which is exhibited by co-administration of vasoconstrictors, especially vasoconstrictors believed to act upon alpha adrenoreceptor sites on blood vessel walls, are provided. In accordance with a preferred embodiment, alpha adrenoreceptor blocking agents are aministered subsequent to the performance of surgery or dentistry under local anesthesia accomplished through co-administration of anesthesia and vasoconstrictor to cause reduction of prolonged anesthetic effect. Seriatim procedures are facilitated under local anesthesia through employment of the present invention. Improved patient aesthetics, diminution of self-inflicted trauma, and increased sensory feedback from patients are among the benefits conferred by the present invention.

  • Patent number: 4622219
    Abstract: Local anesthesia is induced using microdroplets of a general anesthetic in liquid form. As an example, microdroplets of the general anesthetic methoxyfluorane coated by a unimolecular layer of dimysistoyl phosphatidylcholine are prepared by sonication. The microdroplets so prepared remain stable in physiologically-compatible solution, and are suitable for injection, typically intradermally or intraveneously, into a patient for inducing local anesthesia. These methoxyflurane-containing microdroplets have been demonstrated to cause long-term local anesthesia when injected intradermally, giving duration of anesthesia 28 times longer than with other anesthetics, such as lidocaine and 11 times longer than with bupivacaine.

  • Patent number: 4529601
    Abstract: The present invention relates to pharmacological active preparations, especially local anesthetic preparations and deals with the problem of i a obtaining a solution of a local anesthetic agent in the form of its base, where the concentration is higher than otherwise possible. This problem has been dissolved according to the present invention thereby that one local anesthetic agent in the form of its base and as such having a melting point of 30.degree. to 50.degree. C., preferably prilocaine or tetracaine, is provided with one other local anesthetic agent in the form of its base and as such having a melting point of above 30.degree. C., preferably above 40.degree. C., preferably bensocaine, lidocaine, bupivacaine, mepivacaine, etidocaine or tetracaine which agents when brought and heated together form a homogenous oil having a melting of preferably below 40.degree. C., more preferably below 25.degree. C.
