The liquid consisting of or containing a substance having pharmaceutical activity, for instance calcitonin. The nasal dispenser has a very simple structure, it assures a perfect seal and insulation of the liquid retained in it till the moment of its use, and it is made in such a way that the dispensing of the liquid in atomized form occurs only after at least a minimum pressure having a predetermined value has been given, thus avoiding droppings of the liquid outside of the dispenser discharging nozzle.
