Step 1: Open the suction device. Open the dust cap first, then pull the dust cap upward to expose the inhalation nozzle. Step 2: Place the capsule into the inhalation device by pressing the nozzle and pulling it upward to expose the central chamber with the hole and place the capsule. Step 3: Pierce the capsule. Keep the dust cap open and press the nozzle firmly until you hear a cracking sound. Keep the mouthpiece open and press the piercing button to the end. Step 4: Inhale the medication. Start by exhaling 1 deep breath, but avoid exhaling into the inhalation device. Keep your head upright, eyes flat in front, lift the inhaler so that it is parallel to your mouth, do not block the inlet, wrap your lips together around the inhaler and inhale deeply and long, at this time you can feel the capsule vibrate, remove the inhaler, hold your breath and breathe normally again after 10 seconds. Step 5: Finally, open the mouthpiece, pour out the used capsule and throw it away, close the mouthpiece and dust cap. When the device does not have medicine, you can rinse it with water once a week, dry it and use it again. Note 1. As a maintenance drug, it should not be used in acute attacks, i.e., it should not be used as a rescue treatment drug. 2. There is a possibility of immediate allergic reaction, which may cause inhalation bronchospasm. 3. It should be used with caution in patients with narrow-angle glaucoma, prostatic hyperplasia or bladder neck obstruction. 4. Care should be taken to avoid getting the drug powder into the eyes. 5. It is mainly excreted by the kidneys. For patients with moderate or severe renal insufficiency, the advantages and disadvantages should be weighed. Q & A 1. What are the benefits of inhalation therapy? Inhaled drugs reach the lungs directly, with fast onset of action, low dosage, good safety, and suitable for long-term use. Oral medications are slower to work and have more systemic side effects. 2. Is it possible to treat without medication? The cost of hospitalization for one acute exacerbation is equivalent to the cost of two and a half years of domestic tiotropium bromide use, therefore, long-term use of the drug can reduce the overall medical costs, more importantly, it can reduce acute exacerbations, reduce mortality, prolong life and improve the quality of life. 3. How do I know that the powder has been absorbed? When pouring out the empty capsule, observe whether there is any powder left in the capsule and the device, if there is no powder, it proves that all of it has been inhaled, if there is still powder, it proves that the inhalation is not sufficient, you can close the nozzle and inhale the drug again. If your inhalation power is insufficient, you can choose to inhale several times.
