An inhalation capsule is a type of dosage form that is used to deliver medication directly to the lungs. The capsule contains a dry powder form of the medication and is inserted into a device, such as a dry powder inhaler (DPI), that converts the powder into a fine mist or spray for inhalation. This method of delivery is commonly used for respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD), as well as for delivering medications directly to the lungs. Inhalation capsules are effective because they allow the medication to be absorbed directly into the bloodstream through the lungs, bypassing the digestive system. Proper technique is important when using an inhalation capsule to ensure that the medication is delivered effectively to the lungs. It is also important to follow the manufacturer's instructions for using the inhalation device and to keep it clean and well-maintained.
