Abstract
A dispensing device having a container body defining a solution retaining chamber therein, the container having an outlet for dispensing the solution from the chamber and means for removing a component from the solution as the solution is dispensed from the chamber through the container outlet. A method is provided for administering to a patient a pharmacologically active substance which substance is stable only at a pH value which is extreme in the acidic or alkaline region and at which pH value the substance cannot be administered without causing discomfort and/or injury to the patient. The substance is maintained in a solution or dispersion at the pH at which it is stable until the time of administration. At this time the substance is administered through a chamber containing an ion exchange resin which changes the pH of the solution or dispersion to a value which will not cause discomfort and/or injury to the patient.
