Inhalers A-Z

Types of inhalers

There are two types of medications that can be taken through the inhalers– Controllers or Preventer (these help control your symptoms) and Relievers (these provide instant relief in case of exacerbation of symptoms or an asthma attack). Inhalers have been proved to be the safest and most effective way to treat and control asthma and COPD, as the inhaled medication reaches the lungs directly.

Broadly, the inhaler devices can be classified under 4 categories – Pressurised Metered Dose Inhalers (pMDIs), Dry Powder Inhalers (DPIs), Breath Actuated Inhalers (BAIs)and Nebulizers.

1. Pressurised Metered Dose Inhalers (pMDIs)

Also known as pump inhalers, these are the most commonly used inhaler devices. They are propellent-based and deliver a specific, amount of medication to the lungs, in the form of aerosol spray; which needs to be inhaled. It releases reproducible doses every time on actuation. This means that the same amount of dose is released every time. These inhalers do not depend upon the patient’s inhalation to trigger the release of the drug. They require co-ordination between the actuation of the canister and inhalation of the dose. To put it simply, you must inhale and simultaneously press the canister to release the medication dose. pMDIs also come with a dose counter, making it easy to keep track of the number of puffs remaining in the device.

Below mentioned devices can be attached to the pMDI, to ease it’s use.

  • Zerostat VT Spacer

Zerostat VT spacer can be attached to the pMDI. It holds the medication for a little while after the pMDI’s actuation. Thus, the spacer helps you inhale all the medication, even if you do not inhale exactly at the same time when the pMDI canister is pressed for releasiung the medication.

  • Baby Mask

If your child is unable to hold the Zerostat VT Spacer’s mouthpiece properly, you can attach the baby mask to the Zerostat VT Spacer and then use the pMDI.

With the help of the BabyMask your child can easily inhale the medicine, while breathing in & out through the mouth normally. It is also useful for those who have difficulty in maintaining a good lip seal on the mouth piece of the pMDI.

  • Huf Puf Kit

The spacer and baby mask come preassembled in a Huf Puf Kit. As it is preassembled, it helps deliver the medication quickly in case of an emergency and saves time.

2. Dry Powder Inhalers (DPIs)

These types of inhalers deliver the medication in a dry powder form. DPIs are breath-actuated devices, which depend on your inhalation, to release the medication from the device. In comparison to the pMDIs, these are easier to use as they don’t need propellants and co-ordination. Usually, DPIs are single dose devices, although multi-dose DPIs are available as well.

  • Revolizer

The Revolizer is an easy to use DPI, usually used with medication capsules known as rotacaps. It provides an accurate medication dose and a more efficient dispersal, even when the inhalation flow rates are low.

  • Rotahaler

The Rotahaler is an easy to use completely transparent DPI. It is usually used with medication capsules known as rotacaps. Since it is completely transparent, it enables you to make sure that you have inhaled the entire medication.

  • Multihaler

The Multihaler contains preloaded doses in a blister strip, so you do not have to insert a capsule every time you need to take a dose. When you twist (or rotate) the device, it pierces the blister and releases a drug dose. Multihaler also has a dose counter, which enables you to monitor the number of doses remaining in the device.

3. Breath Actuated Inhalers (BAIs)

An advanced version of the pMDI technology, the breath-actuated inhaler combines the advantages of a pMDI and DPI. The BAI senses your inhalation through an actuator, and releases the medication automatically.

  • Autohaler

The autohaler is by far easier to use than a pMDI and some of the DPIs. It can be used effectively by everyone – children, adults and elderly.

4. Nebulizers

Unlike pMDIs and DPIs, nebulizers convert the liquid medication into suitable aerosol droplets, which are best suited for inhalation. Nebulizers do not require coordination and deliver the medication quickly and effectively to the lungs in the form of a mist. Nebulizers are preferred during asthma attacks, in infants, children, te elderly, critical, patients unconscious patients, and those who cannot use a pMDI or DPI effectively.
