Renafor-B Inhalation Capsule 400 mcg + 12 mcg is a high-potency dry-powder inhalation therapy designed for the long-term management of severe asthma and chronic obstructive pulmonary disease (COPD). It combines Budesonide, a potent inhaled corticosteroid, with Formoterol Fumarate, a long-acting beta-2 adrenergic agonist (LABA). This dual-action therapy provides strong anti-inflammatory control and sustained bronchodilation, offering comprehensive symptom management for patients with persistent respiratory conditions.

Budesonide reduces airway inflammation, prevents swelling, and limits mucus production, targeting the root causes of chronic airway obstruction. Formoterol Fumarate relaxes bronchial smooth muscles, improving airflow and making breathing easier. The 400 mcg dose of Budesonide provides maximum anti-inflammatory effect, while the 12 mcg of Formoterol ensures prolonged bronchodilation for optimal symptom control.

Administered via a dry-powder inhaler device, Renafor-B 400/12 mcg delivers the medication directly to the lungs, ensuring rapid onset and effective long-term management. Regular use can reduce exacerbations, improve lung function, and enhance quality of life in patients with severe asthma or COPD.

Composition

Each inhalation capsule contains:

• Budesonide – 400 mcg

• Formoterol Fumarate – 12 mcg

Mechanism of Action

Renafor-B Inhalation Capsules act through the combined effects of its components:

• Budesonide: Suppresses airway inflammation by inhibiting inflammatory cells and mediators, reducing swelling, mucus secretion, and airway hyper-responsiveness.

• Formoterol Fumarate: Activates beta-2 adrenergic receptors in airway smooth muscles, producing long-lasting bronchodilation that improves airflow and eases breathing.

Together, these mechanisms provide both long-term prevention of flare-ups and immediate symptom relief, making it highly effective for patients with severe respiratory disease.

Indications

Renafor-B 400/12 mcg is indicated for:

• Severe persistent asthma requiring high-dose inhaled corticosteroids

• Severe COPD with frequent exacerbations or persistent symptoms

• Patients inadequately controlled with lower-dose inhalation therapies

• Long-term maintenance therapy to reduce airway inflammation and prevent exacerbations

This inhaler is for maintenance therapy only and is not suitable as a rescue inhaler for sudden asthma attacks.

Dosage and Administration

The dosage should be determined by a healthcare professional based on disease severity:

• Typical dose: 1 capsule inhaled twice daily or as prescribed

• Place the capsule in the dry-powder inhaler device

• Exhale fully, position the mouthpiece in the mouth, and inhale deeply to ensure the medication reaches the lungs

• Hold the breath for 5–10 seconds before exhaling

• Do not swallow the capsule; it is for inhalation only

• Rinse the mouth after use to prevent oral thrush caused by Budesonide

Consistency in daily use is essential for effective symptom control.
