A method for accelerating subcutaneous absorption of a fluid or drug into the systemic circulation of a specific targeted tissue. A first drug operative to produce local capillary vasodilatation and/or increase the rate of bulk flow of solution through the interstitial space is mixed with a fluid. The fluid may contain a crystalloid solution or a dilute solution of a pharmacologic drug required for a routine or emergency therapeutic treatment for a patient. The first drug is substantially non-toxic to the patient. The fluid mixed with the first drug is then delivered subcutaneously or into deeper tissues of the patient, by use of a hyperdermic needle or infiltration cannula. As the capillaries are dilated, the fluid is efficiently absorbed and circulated systemically.
