An inhaler having a hollow inhaler body for retaining an aerosol container with a dispensing valve at a valve end of the container, the inhaler body comprising: - a first open end sized and arranged to receive the aerosol container with a dispensing valve; - a second open end through which a dose of medicament is dispensed as an aerosol, the second open end being sized and arranged to be coupled to the mouth or nasal cavities of a patient; - a nozzle block (5, 5') with an upper portion and a lower portion positioned adjacent to one another, the nozzle block (5, 5') extending along a longitudinal axis from a bottom portion of the inhaler body towards the first open end, wherein the nozzle block (5, 5') is configured such that a dose of a medicament is released upon depression of the dispensing valve of the aerosol container against the nozzle block (5, 5'), the nozzle block (5, 5') having a fluid flow path extending therethrough such that the dose of medicament being released from the valve is passed to the nozzle block (5, 5') and exits the nozzle block (5, 5') as an aerosol in a direction towards the second open end of the inhaler body; wherein the nozzle block (5, 5') is formed as a part separate from the inhaler body, wherein the bottom portion of the inhaler body comprises a receiving portion (11, 11') for receiving the nozzle block (5, 5')and wherein the nozzle block (5, 5') is adapted to be inserted through the first open end of the inhaler body into the receiving portion (11, 11') of the bottom portion, wherein the nozzle block has two supporting legs for vertically supporting the nozzle block in the receiving portion, wherein each of the supporting legs has a lower end with an alignment plate protruding transversely to the longitudinal axis of the nozzle block from the corresponding supporting leg in an outward direction and being configured to rest against a corresponding protrusion of the receiving portion, wherein the alignment plates protrude in opposing directions and wherein the corresponding protrusions of the receiving portion oppose each other, and characterized in that the nozzle block further has a rib which extends parallel to the supporting legs from the upper portion along the lower portion and is located between the supporting legs, wherein the rib is adapted to engage with a vertically extending groove in the receiving portion. - a first open end sized and arranged to receive the aerosol container with a dispensing valve; - a second open end through which a dose of medicament is dispensed as an aerosol, the second open end being sized and arranged to be coupled to the mouth or nasal cavities of a patient; - a nozzle block (5, 5') with an upper portion and a lower portion positioned adjacent to one another, the nozzle block (5, 5') extending along a longitudinal axis from a bottom portion of the inhaler body towards the first open end, wherein the nozzle block (5, 5') is configured such that a dose of a medicament is released upon depression of the dispensing valve of the aerosol container against the nozzle block (5, 5'), the nozzle block (5, 5') having a fluid flow path extending therethrough such that the dose of medicament being released from the valve is passed to the nozzle block (5, 5') and exits the nozzle block (5, 5') as an aerosol in a direction towards the second open end of the inhaler body; wherein the nozzle block (5, 5') is formed as a part separate from the inhaler body, wherein the bottom portion of the inhaler body comprises a receiving portion (11, 11') for receiving the nozzle block (5, 5')and wherein the nozzle block (5, 5') is adapted to be inserted through the first open end of the inhaler body into the receiving portion (11, 11') of the bottom portion, wherein the nozzle block has two supporting legs for vertically supporting the nozzle block in the receiving portion, wherein each of the supporting legs has a lower end with an alignment plate protruding transversely to the longitudinal axis of the nozzle block from the corresponding supporting leg in an outward direction and being configured to rest against a corresponding protrusion of the receiving portion, wherein the alignment plates protrude in opposing directions and wherein the corresponding protrusions of the receiving portion oppose each other, and characterized in that the nozzle block further has a rib which extends parallel to the supporting legs from the upper portion along the lower portion and is located between the supporting legs, wherein the rib is adapted to engage with a vertically extending groove in the receiving portion.
