A dry powder inhaler (DPI) capsule is a type of medication used in conjunction with a dry powder inhaler device. The capsule contains a dry powder form of the medication, which is dispensed by the patient breathing in through the inhaler. The dry powder form allows for fast and efficient delivery of the medication to the lungs, providing quick relief of symptoms. DPIs are commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). The capsule form of the medication is convenient and easy to use, making it a popular choice for many patients. Proper technique and use of the inhaler is important for ensuring maximum efficacy and minimizing side effects. It is important to follow the instructions on the label and to use the inhaler exactly as prescribed by a healthcare provider.
