Abstract
A device for use with metered dose inhalers includes a housing configured with a void to receive a metered dose inhaler, an actuator assembly which is configured to selectively apply force to the metered dose inhaler to cause the metered dose inhaler to release medicament, and a cocking mechanism for placing the actuator assembly in an armed configuration. The device is configured to actuate the metered dose inhaler as the user inhales, thereby ensuring improved medicament delivery. Additionally, the device is configured to prevent the metered dose inhaler from remaining in a vented position.
