An aerosolization device for providing aerosolized medicament to a user, the aerosolization device comprising: a conduit having an inner wall and a mouthpiece end by which a user may cause an inspiratory flow through the conduit ; an aerosol generator in communication with the conduit and comprising a vibratable mesh ; a fluid receiving chamber in communication with the aerosol generator for receiving a volume of a liquid medicament, wherein at least a portion of the fluid receiving chamber is tapered such that substantially all of the liquid medicament is directed onto the vibratable mesh for aerosolization; and a restrictor disposed within the conduit , wherein the restrictor defines a plurality of apertures, the plurality of apertures being configured to: provide an increase in pressure differential that varies with an inspiratory flow rate within the conduit ; and wherein the aerosol generator is configured to aerosolize at least a portion of the volume of the liquid medicament only when the one or more flow parameters of the inspiratory flow are within the predefined desired range, characterized in that the vibratable mesh is disposed at a distance from the inner wall of the conduit such that a lower surface of the vibratable mesh is offset from the most proximate wall of the conduit to laterally offset the vibratable mesh from the inner wall , and the plurality of apertures being configured to: provide a relatively laminar flow downstream of the restrictor plate compared to upstream of the restrictor plate. a conduit having an inner wall and a mouthpiece end by which a user may cause an inspiratory flow through the conduit ; an aerosol generator in communication with the conduit and comprising a vibratable mesh ; a fluid receiving chamber in communication with the aerosol generator for receiving a volume of a liquid medicament, wherein at least a portion of the fluid receiving chamber is tapered such that substantially all of the liquid medicament is directed onto the vibratable mesh for aerosolization; and a restrictor disposed within the conduit , wherein the restrictor defines a plurality of apertures, the plurality of apertures being configured to: provide an increase in pressure differential that varies with an inspiratory flow rate within the conduit ; and wherein the aerosol generator is configured to aerosolize at least a portion of the volume of the liquid medicament only when the one or more flow parameters of the inspiratory flow are within the predefined desired range, characterized in that provide an increase in pressure differential that varies with an inspiratory flow rate within the conduit ; and wherein the aerosol generator is configured to aerosolize at least a portion of the volume of the liquid medicament only when the one or more flow parameters of the inspiratory flow are within the predefined desired range, characterized in that the vibratable mesh is disposed at a distance from the inner wall of the conduit such that a lower surface of the vibratable mesh is offset from the most proximate wall of the conduit to laterally offset the vibratable mesh from the inner wall , and the plurality of apertures being configured to: provide a relatively laminar flow downstream of the restrictor plate compared to upstream of the restrictor plate. <EOS>
