Inhalation Products, especially metered dose inhaler
An inhaler is a medical device used for delivering medicines into the lungs through the work of a person’s breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications. Two of the most common conditions that warrant inhaler therapy are asthma and chronic obstructive pulmonary disease (COPD).
Asthma is a condition of intermittent airway obstruction due to inflammatory processes in the lungs. Inhaled medications are used to calm down the inflammation present in the lungs and allow for relief of the airway obstruction. COPD is an obstructive lung disease due to long-term damage to the airways of the lung. The long-term damage leads to the inability of the airways to open properly, causing airway obstruction. Inhaled medications allow for patient’s to see improvement in symptoms and better function of daily living.
Some of the common types of inhalers include meter-dosed inhalers, dry powder inhalers, soft mist inhalers, and nebulizers. Each device has advantages and disadvantages and can be selected based on specific patient needs, as well as age, coordination, and lung function.
Meter-dosed Inhalers (MDI)
The most common type of inhaler is the pressurized metered-dose inhaler (MDI) which is made up of 3 standard components- a metal canister, plastic actuator, and a metering valve. The medication is typically stored in solution in a pressurized canister that contains a propellant or suspension. The MDI canister is attached to a plastic, hand-operated actuator. On activation, the metered-dose inhaler releases a fixed dose of medication in aerosol form through the actuator and into a patient’s lungs.
SPH Phililab has an equipment line and devices resources of developing MDI type of products. We specialized in developing suspension and solution type of MDI using HFA as propellant, that is a non-ozone depleting compound.
