Abstract
Abstract A method is provided for treating high blood pressure and disturbances of cardiac function by administering a therapeutically effective dosage of dynorphin-related opioid peptides, such as dynorphin(1-13) and dynorphin(1-10) amide, having at least ten amino acids linked sequentially by peptide bonds and with the five amino acids from the N-terminal end being the same as, or mimicking, Leu-enkephalin. Administration may be over a period of time, as for individuals with chronic high blood pressure, and may be by dispensing the medicament in aerosol form.
