An inhaler with a respiration indicator, whereby the inhaler has a chamber wall forming a chamber and a dispensing device for fluidic connection of the chamber to a bodily opening, preferably a nostril, whereby the respiration indicator has a wall section of the chamber wall or is formed in this way, whereby the wall section is designed to indicate a respiratory activity by deformation and/or movement.

Systems and methods for delivering medicament to a subject use one or more sensors to generate signals that represent characteristics of the ultrasonic energy emitted into or by a respiratory medicament delivery device. Parameters based on these signals indicate energy amplitude in one or more frequency ranges. Such parameters can be used to determine respiratory parameters, patient adherence, and/or other parameters.

An inhalable composition for use as a medicament in the treatment of a subject wherein said composition comprises: one or more cannabinoids or a pharmaceutically acceptable derivative or salt thereof; a propellant; a monohydric or polyhydric alcohol; and a glycol and/or glycol ether,
characterised in that the ratio of monohydric or polyhydric alcohol to glycol or glycol ether by weight is from 6:1 to 1:1, wherein the composition is administered in the form of an aerosol having a fine particle fraction of 60% or more.

An inhalable composition for use as a medicament in the treatment of a subject wherein said composition comprises: one or more cannabinoids or a pharmaceutically acceptable derivative or salt thereof; a propellant; a monohydric or polyhydric alcohol; and a glycol and/or glycol ether, characterised in that the ratio of monohydric or polyhydric alcohol to glycol or glycol ether by weight is from 6:1 to 1:1, wherein the composition is administered in the form of an aerosol having a fine particle fraction of 60% or more.

An aerosol-generating system is provided, including a housing including an air inlet and an air outlet defining an air flow path therebetween; a heater element; and a cartridge moveably mounted in the housing and reversibly displaceable from a first position to a second position, the cartridge including a moveable plunger, a liquid storage portion configured to hold an aerosol-generating liquid, and an opening configured to deliver the aerosol-generating liquid, wherein the cartridge is further configured to activate release of a portion of the aerosol-generating liquid through the opening, when the cartridge is moved by an airstream created between the air inlet and the air outlet within the housing.

An inhaler comprising a reservoir of an inhalable composition. A valve element moved by a flexible diaphragm and biased into a position in which it closes a composition flow path from a reservoir. A first air flow path is partly defined by one side of the diaphragm and a second air flow path is partly defined by the opposite side of the diaphragm. Each flow path has an outlet opening at an outlet end and the second flow path has an inlet upstream of the outlet end. The air flow paths are arranged such that suction at the outlet end causes a reduction in pressure in the first air flow path relative to the pressure in the second air flow path creating a pressure differential across the diaphragm that moves the valve element against the biasing force to open the composition flow path.

An inhaler (60) has a breath actuated trigger mechanism (100) reactive to an inhalation flow to trigger the release of a substance to be inhaled. The inhaler (60) has an inspiration flow which is subject to a higher degree of flow governing post-triggering than pre-triggering. This allows the triggering flow rate to be closer to, or even higher than, the governing flow rate of the inhaler.

Dispensers, in particular dispensers for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source and dispensers containing dosage counters are described herein.

An inhalable composition for use as a medicament in the treatment of a subject wherein said composition comprises: one or more cannabinoids or a pharmaceutically acceptable derivative or salt thereof; a propellant; a monohydric or polyhydric alcohol; and a glycol and/or glycol ether, characterised in that the ratio of monohydric or polyhydric alcohol to glycol or glycol ether by weight is from 6:1 to 1:1, wherein the composition is administered in the form of an aerosol having a fine particle fraction of 60% or more.

The present invention provides a two-step mechanism for delivering a flowable substance to the nasal passages, comprising: a. a nosepiece adapted to be in fluid connection with said nasal passages; b. at least one air-tight enclosure, comprising predetermined amount of compressed gas in the same; said compressed gas is pressurized to predetermined amount of pressure; c. a charging mechanism, fluidly connected with said air-tight enclosure, characterized by at least two configurations: a retracted position and an extended position; where, when said charging mechanism is transformed from said extended position to said retracted position, said charging mechanism is adapted to enable delivery of said pressurized and predetermined amount of compressed gas from at least one first predetermined position in said air-tight enclosure to at least one second predetermined position; d. an activation mechanism, adapted to entrain said flowable substance within said pressurized and predetermined amount of compressed gas.
