Analysis of how long a box of ensifentrine-Ohtuvayre can be used and the dosage of the treatment course

Ensifentrine (Ensifentrine), trade name Ohtuvayre, is a new inhaled dual phosphodiesterase inhibitor, mainly used to treat chronic obstructive pulmonary disease (COPD). It inhibits PDE3 and PDE4 dual effects, simultaneously exerting bronchodilator and anti-inflammatory effects, improving respiratory function, relieving shortness of breath and reducing chronic inflammatory reactions. Ohtuvayre is suitable for patients who require long-term control of COPD symptoms and can be used as part of maintenance treatment.

Based on clinical guidelines and prescribing information, the recommended dose of Ohtuvayre is one ampoule (3 mg) twice daily for inhalation in the morning and evening. Each inhalation takes about 5–7 minutes and needs to be operated with a matching spray atomizer to ensure that the drug fully enters the lower respiratory tract and exerts maximum efficacy. Patients should strictly follow the doctor's instructions and not increase or decrease the dose or adjust the number of inhalations at will.

Ohtuvayre Usually sold in boxes of 5 ampoules, each box provides approximately 2.5 days of continuous use when used twice daily. For COPD patients who require long-term maintenance treatment, multiple boxes of medications should be prepared in advance to ensure continuous medication. At the same time, the opened ampoule should be used within 14 days to avoid the decrease in drug activity or affect the stability and ensure the therapeutic effect.

When using Ohtuvayre , you should pay attention to the storage conditions of the drug, avoid high temperature, humidity and direct sunlight, and do not mix it with other drugs for inhalation. Patients should regularly review lung function, symptom scores and adverse reactions during treatment. If severe cough, throat irritation or difficulty breathing occur, you should contact your doctor promptly to adjust the treatment plan. Through standardized use and regular monitoring, Ohtuvayre can effectively improve the respiratory function and quality of life of COPD patients.
