Aerosol-based inhalers, often known as metered-dose inhalers, can be substituted with DPIs (or MDI). The DPIs might need to go through a process before the patient can take a measured dose of powder. Commonly, the drug is kept inside the inhaler in a unique form or in a capsule for manual loading. The user inserts the inhaler’s mouthpiece into their mouth after it has been loaded or activated, inhales sharply and deeply (ensuring that the drug reaches the lower portions of the lungs), and holds their breath for five to ten seconds. These devices come in a variety. Larger powder doses may cause side effects, thus the maximum dose that can be administered in a single breath is normally less than a few tens of milligrams.
While DPIs are frequently used to treat lung-based illnesses, using them effectively needs dexterity to carry out the necessary sequential procedures. The administration of the administered medication and, thus, its effectiveness and safety, can be significantly reduced by improperly completing one or more procedures in the use of a DPI. Between 50 and 100 percent of patients misuse their inhaler devices, according to numerous studies, and many of these patients are unaware that they are misusing their inhaled medication. Incorrect inhaler technique has been linked to less favourable results.
Storing Your Keyhaler
Keep the cap on your inhaler. This keeps dust and debris out meaning you won’t breathe it in.
Keep your inhaler at the correct temperature.
Keep your inhaler somewhere dry.
Store all medicines safely, out of reach of children and pets.
Since exposure to moisture impairs the powder’s capacity to be dispersed by the device as a fine powder when inhaled, DPI medication must be maintained in a dry location with humidity between 40 and 50% and a temperature of no higher than 25 °C (77 °F). Additionally, some medications demand photo security.
