Medicament inhaler and method

A method of administering a fluidized powder medicament to a person through inhalation, said method comprising:

• providing an inhalation tube having a first, downstream end for the person to draw air therethrough and a second remote, upstream end;
• providing a medicament holder for holding a quantity of medicament, the medicament holder having at least one air entry hole defining an air entry hole size and at least one air exit hole defining an air exit hole size, the air entry hole size being substantially smaller than the air exit hole size so as to cause the powder to fluidize inside the medicament holder when air enters through the at least one air entry hole and exits through the at least one air exit hole;
• providing a holding chamber defined in the inhalation tube upstream of the first end and immovably holding therein said medicament holder relative to said inhalation tube;
• providing an air passage in the inhalation tube and creating a flow of air from said air passage to said first downstream end through suction of the person inhaling through the first end of the tube;
• fluidizing the medicament while the medicament is still located inside said medicament holder;
• and
• delivering said fluidized medicament from inside said medicament holder into a portion of the inhalation tube located downstream of said medicament holder and carrying the fluidized medicament by the air flowing from the air passage into the body of the person inhaling through the tube .
