One or more kinds of metal or metallic substances and/or deficiency and/or trace elements and in a given case the active ingredients of some known pharmaceutical agent is applied to a carrier. The deficiency and/or trace element and in a given case the active ingredient of the known pharmaceutical agent medicament, which are present, are applied in form of a powder, a liquid or in gaseous form. The powdered, liquid and gaseous substances are placed into a recipient, e.g. bag with a permeable wall onto the carrier. Preferably, adhesive strips are provided on the margins of the carrier, while the substances on the carrier are covered with a removable protective layer. If required, the carrier is pretreated with a weak base or acid prior to the application thereof.

  • Patent number: 4725442
    Abstract: Microdroplets of water-insoluble drugs coated with a phospholipid are prepared by sonication. 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. The latter is considered longest acting conventional local anesthetic.
