What is Ohtuvayre?
Ohtuvayre (ensifentrine) is an inhaled dual phosphodiesterase treatment that may be used to improve symptoms and reduce the number of flare ups of chronic obstructive pulmonary disease (COPD) in adults. It must be used with a nebulizer and it is not intended as a rescue treatment to relieve sudden breathing problems.
Ohtuvayre has combined bronchodilator and non-steroidal anti-inflammatory actions and works by inhibiting two enzymes, phosphodiesterase 3 (PDE3) and phosphodiesterase 4 (PDE4) that are highly expressed in the smooth muscle of the lungs. These enzymes hydrolyze (break down) cyclic AMP, which is an important cellular messenger for many different physiological processes, including bronchial smooth muscle relaxation and blocking substances that contribute to inflammation. Decreasing PDE3 activity relaxes airway muscles and prevents symptoms such as wheezing, coughing, chest tightness, and shortness of breath. Decreasing PDE4 activity helps to decrease inflammation in the lungs, which can lead to breathing problems.
Ohtuvayre was FDA-approved on 26 June 2024.

How do I take Ohtuvayre?
Ohtuvayre should only be used with a standard jet nebulizer with a mouthpiece connected to an air compressor.
- Shake the Ohtuvayre ampule vigorously immediately before using it. When shaken, it will appear cloudy and yellow to pale yellow in color.
- Use 1 ampule of Ohtuvayre 2 times a day, 1 time in the morning and 1 time in the evening.
- Do not use more than 1 ampule in a single treatment. Do not use more than 2 ampules a day.
- Squeeze the contents of the ampule into the nebulizer cup and discard the ampule.
- Do not mix other medicines with Ohtuvayre in your nebulizer.
Do not use it unless your healthcare provider has taught you how to use it with your nebulizer and you understand how to use it correctly.
- Use it exactly as your healthcare provider tells you to use it.
- Do not use Ohtuvayre more often than prescribed.
Call your healthcare provider or get emergency medical care right away if:
- your breathing problems get worse
- you need to use your inhaled rescue medicine more often than usual
- your inhaled rescue medicine does not relieve your symptoms.
Do not stop using Ohtuvayre even if you are feeling better unless your healthcare provider tells you to because your symptoms might get worse.
Throw away the Ohtuvayre ampules immediately after use. Due to their small size, the ampules pose a danger of choking to young children.
What happens if I miss a dose?
If you miss a dose of Ohtuvayre, take it as soon as you remember, but if it is almost time for your next dose, skip that dose and go back to your usual dosing schedule. Do not double up on Ohtuvayre doses.
What happens if I overdose?
If you use too much Ohtuvayre call your healthcare provider or go to the nearest hospital emergency room right away if you have any unusual symptoms, such as increased heart rate or headaches.
- Ohtuvayre does not relieve sudden symptoms of COPD and you should not use extra doses to relieve these sudden symptoms.
Always have an inhaled rescue medicine with you to treat sudden symptoms. If you do not have an inhaled rescue medicine, call your healthcare provider to have one prescribed for you.
