Overview

ℹ️

What is this medicine?

Ohtuvayre is an inhaled medicine used to help people with Chronic Obstructive Pulmonary Disease (COPD) breathe easier. It works by relaxing the muscles around your airways and reducing inflammation in your lungs, which helps to open up your air passages. It is given using a nebulizer, which turns the liquid medicine into a fine mist that you breathe in.

How to Use This Medicine

Proper Use of This Medication

To use this medication correctly, follow your doctor's instructions and read all the information provided. You will inhale this medication through your mouth using a special machine called a nebulizer. Your doctor will teach you how to use the nebulizer properly. Be sure to use only the type of nebulizer recommended by your doctor. If you're unsure, consult with your doctor.

Important Administration Instructions

Do not swallow this medication.
Do not mix this medication with any other liquid medications.
Do not add other medications to the nebulizer.
Do not open the ampule until you are ready to take a dose.
After opening, discard any unused portion of the ampule.
Shake the solution well before use. The solution should appear cloudy and yellow to pale yellow. Do not use if the solution changes color or appears cloudy, leaking, or contains particles.

Nebulizer Care and Maintenance

Follow the instructions for cleaning the nebulizer carefully. Each ampule is for single use only. After using an ampule, dispose of it in the trash, out of the reach of children, as it may pose a choking hazard.

Taking Multiple Inhaled Medications

If you are taking more than one inhaled medication, consult with your doctor to determine the best order for taking your medications.

Pharmacology

πŸ”¬

Mechanism of Action

Ensifentrine is a first-in-class, non-selective phosphodiesterase 3 (PDE3) and phosphodiesterase 4 (PDE4) inhibitor. By inhibiting both PDE3 and PDE4, ensifentrine increases intracellular cyclic adenosine monophosphate (cAMP) levels in airway smooth muscle cells and inflammatory cells. Increased cAMP leads to bronchodilation by activating protein kinase A (PKA), which relaxes smooth muscle. It also exerts anti-inflammatory effects by modulating immune cell function and reducing the release of pro-inflammatory mediators.

Drug Interactions

🟑

Moderate Interactions

  • Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): May increase ensifentrine exposure. Use with caution.
  • Strong CYP3A4 inducers (e.g., rifampin, carbamazepine): May decrease ensifentrine exposure. Use with caution.

Monitoring

πŸ”¬

Baseline Monitoring

Pulmonary Function Tests (FEV1)

Rationale: To establish baseline lung function and assess disease severity.

Timing: Prior to initiation of therapy

Patient's symptom burden (e.g., dyspnea, cough)

Rationale: To establish baseline and monitor therapeutic response.

πŸ“Š

Routine Monitoring

Pulmonary Function Tests (FEV1)

Frequency: Periodically, as clinically indicated (e.g., every 3-6 months)

Target: Improvement from baseline

Frequency: Regularly, especially during initial weeks of therapy and with dose changes

Target: Absence or tolerability of side effects

Action Threshold: Persistent or severe adverse effects warrant dose adjustment or discontinuation

COPD symptom control

Frequency: At each follow-up visit

Target: Reduction in frequency and severity of symptoms

Action Threshold: Worsening symptoms or increased exacerbations require reassessment

Special Patient Groups

🀰

Pregnancy

There are no adequate and well-controlled studies of Ohtuvayre in pregnant women. Animal studies have not shown evidence of developmental toxicity. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Trimester-Specific Risks:

First Trimester: No specific data; theoretical risk based on animal studies is low.
Second Trimester: No specific data; theoretical risk based on animal studies is low.
Third Trimester: No specific data; theoretical risk based on animal studies is low.
🀱

Lactation

It is not known whether ensifentrine is excreted in human milk. Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for Ohtuvayre and any potential adverse effects on the breastfed infant from Ohtuvayre or from the underlying maternal condition.

Infant Risk: Unknown; potential for systemic effects in infant is low due to low systemic absorption in mother, but caution is advised.
πŸ‘Ά

Pediatric Use

Safety and effectiveness in pediatric patients (under 18 years of age) have not been established for COPD. Ohtuvayre is not indicated for use in pediatric patients.

πŸ‘΄

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly and younger adult patients. No dose adjustment is required based on age.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Ohtuvayre is a novel, first-in-class dual PDE3/PDE4 inhibitor, offering both bronchodilator and anti-inflammatory effects in a single inhaled medication.
  • It is administered via nebulizer, which may be beneficial for patients who struggle with inhaler technique or have severe airflow limitation.
  • Unlike inhaled corticosteroids, ensifentrine is a non-steroidal anti-inflammatory agent, potentially offering an alternative for patients who cannot tolerate or do not respond well to steroids.
  • It is approved for maintenance treatment of COPD and should not be used for acute bronchospasm.
  • Patients should be instructed on proper nebulizer use and maintenance.
πŸ”„

Alternative Therapies

  • Long-acting beta-agonists (LABAs) e.g., salmeterol, formoterol, indacaterol, olodaterol
  • Long-acting muscarinic antagonists (LAMAs) e.g., tiotropium, aclidinium, glycopyrronium, umeclidinium
  • Inhaled corticosteroids (ICS) e.g., fluticasone, budesonide, mometasone (often in combination with LABA)
  • Combination LABA/LAMA inhalers
  • Combination ICS/LABA inhalers
  • Oral phosphodiesterase-4 inhibitors (e.g., roflumilast)
  • Oral corticosteroids (for exacerbations)
  • Theophylline (less common due to narrow therapeutic index)
