Easypod: a new electronic injection device for growth hormone.

The easypod is the first automated electronic injection device for growth hormone delivery. To save user's time and reduce administration error, the dose is preset by a physician or nurse; in addition, to allow patient adherence to be monitored, the time, date and dose (mg) of each injection is recorded. Details of the last injection and number of doses remaining in the cartridge are also displayed in order to help patients manage the injection schedule. Drug use can be optimized by splitting the dose over two cartridges, with an automatic compensation facility to avoid under-dosing. Patients can customize the depth, speed and duration of the injection. In a user trial, easypod was very well accepted. This review places easypod in the context of current and future growth hormone devices.
