Introduction to the dosage of levodopa inhalation powder spray (Inbrija)

Levodopa inhalation powder (Inbrija) is an innovative drug used to treat the recurrence of symptoms in patients with Parkinson's disease during the "OFF" phase. Parkinson's disease is a chronic neurological disorder characterized by symptoms such as tremors, muscle stiffness, and slowed movements, often caused by insufficient dopamine levels in the brain. Levodopa inhalation powder spray can quickly deliver levodopa to the lungs through inhalation, and then quickly enter the blood circulation and reach the brain, helping patients quickly relieve symptoms during the "OFF" period. It should be noted that levodopa inhalation powder can only be used in combination with levodopa/carbidopa therapy and cannot be used alone as a treatment.

Levodopa inhalation powder spray is administered through a dedicated inhalation device. Each inhalation capsule contains 84 mg of levodopa. When using it, patients should put the capsule into the levodopa inhalation powder inhaler and inhale the drug powder into the lungs through the inhalation device. Capsules should not be swallowed whole or the desired effect will not be obtained. When patients with Parkinson's disease begin to experience a return of "OFF" phase symptoms, 84 mg should be taken by oral inhalation as needed, up to 5 times daily. The maximum dose per "OFF" period is 84 mg, and the maximum daily dose is 420 mg.

During the medication process, patients should strictly follow the doctor's advice and avoid increasing or decreasing the dosage or changing the frequency of medication on their own. If you miss a dose, you should take it as soon as you remember. However, if it is close to the next dose, there is no need to take it again. Just take the dose as originally planned. In addition, patients should undergo regular follow-up consultations while using levodopa inhalation powder, and doctors will adjust the medication plan according to changes in condition and side effects. Through rational medication and regular follow-up, levodopa inhalation powder can effectively improve the "OFF" symptoms of patients with Parkinson's disease and improve their quality of life.
