What are Spacers?

Spacers, also known as holding chambers or inhaler chambers, are add-on devices used with pressurised metered-dose inhalers (pMDIs) to enhance medication delivery and coordination during inhalation.

These devices, commonly made of plastic, act as an intermediate chamber that holds the medication released from the pMDI, allowing patients to inhale at their own pace and facilitating more of the drug reaching the lungs.
