A dispenser for pharmaceutical solutions which includes membranes which are placed in a dropper of the dispenser and are used to achieve the flow of essentially all the active product and the retention of essentially all the preservative during pharmacological treatment. The membrane is coupled between two cylinder units on parts of the dropper, which remain in a relatively movable position, owing to the existence of a certain play between the cylinder units; or the cylinder units may be in a relatively fixed position, owing to the lack of such play. The cylinder unit may also be in a fixed position but with a membrane treated adequately so as to have a small area or "stain" that permits the flow of air.
