The method of reducing pain in a patient by combining a traditional pharmacological treatment with electro-acupuncture or percutaneous electrical nerve stimulation therapy. The pharmacological treatment consists of using analgesics such as morphine sulfate and hydromorphine provided to patients around the clock or as needed for pain. The patient controlled analgesia pump (PCA) is used by patients for self-administering of analgesia as needed. After patient stops using PCA pump narcotic and non-narcotic pain medications are administered mostly orally. Typically, there are two pairs of needle electrodes, two on each leg, connected to two separate outputs of the portable electrical stimulator. The constructions of the needle holder and the stimulator allow a patient to move freely and, if necessary, to carry the device during the entire day.

The present invention relates to peptides which are highly biologically and pharmacologically active as therapeutic drug for the treatment of diseases related to hypertension, especially in medical interventions involving dilatation and remodeling of arterial blood vessels, either in the pulmonary or in the systemic circulation.

Stabilizing catheters for delivery of one or more protein drugs to a patient. The stabilizing catheter embodiments of the invention maintain or preserve a biologically/pharmacologically active form of the protein drug for delivery to a site within the body. Particular embodiments include a tubing layered with a hydrophilic and mobile polymer that aids in the maintenance or preservation of an active conformer of the protein drug. These embodiments of the stabilizing catheter prevent site loss of protein drugs, such as insulin. Other embodiments include a tubing that is layered with a material that substantially prevents diffusion of small, insulin formulation-stabilizing molecules out from the catheter, as well as substantially prevents the diffusion of small, insulin formulation-destabilizing molecules into the catheter, during a period of insulin infusion. In effect, these embodiments of the stabilizing catheter maintain the stabilizing effect of a particular insulin formulation, and consequently, substantially prevents occlusions/deposits from being formed during a period set for insulin delivery. Still other embodiments are directed to a combination of these features of the stabilizing catheters of the invention.
