Mechanism of Action

Vilanterol is a long-acting beta-agonist (LABA) that works by stimulating beta-2 adrenergic receptors in the airways, leading to bronchodilation and improved airflow. Fluticasone Furoate is a corticosteroid that reduces inflammation by inhibiting the release of inflammatory mediators and suppressing immune responses in the airways. Together, these components help to relieve symptoms and prevent exacerbations of respiratory conditions.

How Long Does It Take to Work?

Vilanterol begins to show its bronchodilatory effects within 30 minutes, with peak effects occurring within 3 to 4 hours. Fluticasone Furoate may take several days to weeks of regular use to achieve its full anti-inflammatory effects and maximum symptom control.

Absorption

Both components of the combination are absorbed through the lungs. Vilanterol has a rapid onset of action with peak plasma levels occurring within 3 to 4 hours. Fluticasone Furoate has a slower absorption rate but provides sustained effects due to its high affinity for corticosteroid receptors in the lungs.

Route of Elimination

Vilanterol is primarily metabolized in the liver and excreted through the urine. Fluticasone Furoate is also extensively metabolized in the liver, with its metabolites excreted primarily in the feces.

Dosage

The usual dosage for this combination is:

One inhalation of the combination product once daily, generally in the evening.
The specific dosage may vary based on individual patient needs and should be adjusted according to the severity of the condition and response to treatment.

Administration

The medication is administered via inhalation using a specific inhaler device. Patients should follow the instructions provided with the inhaler to ensure proper usage and effective delivery of the medication. It is important to rinse the mouth after use to reduce the risk of oral thrush.

Side Effects

Cardiovascular disease (e.g., heart disease, hypertension)
Diabetes
Thyroid disorders
Severe infections

Interaction

Drug interactions may include:

Beta-blockers, which may reduce the effectiveness of Vilanterol.
Inhibitors of CYP3A4 (e.g., ketoconazole), which may increase systemic exposure to Fluticasone Furoate.

Disease Interaction

Use with caution in patients with:

Active or inactive tuberculosis
Severe hepatic impairment
Uncontrolled hypertension

Drug Interaction

Potential drug interactions include:

CYP3A4 inhibitors, which can increase Fluticasone Furoate levels.
Other beta-agonists, which may have additive effects.

Food Interactions

Food interactions are minimal. However, taking the medication with food may help reduce gastrointestinal discomfort.

Pregnancy Use

Breon Inhalation Capsule 25 mcg+100 mcg is categorized as a Category C medication for pregnancy. It should be used during pregnancy only if the potential benefits justify the risks to the fetus. Consult a healthcare provider before use.

Lactation Use

It is not known whether Vilanterol or Fluticasone Furoate are excreted in human breast milk. Use with caution during lactation and consult a healthcare provider if breastfeeding is planned or ongoing.

Acute Overdose

In the event of acute overdose, symptoms may include severe tachycardia, tremors, and hypokalemia. Immediate medical attention should be sought. Treatment typically involves symptomatic management and supportive care.

Contraindication

Storage Conditions

Store the inhaler at room temperature, away from direct sunlight and moisture. Keep out of reach of children. Do not use the inhaler after the expiration date.

Volume of Distribution

The volume of distribution of Vilanterol and Fluticasone Furoate is extensive, indicating distribution throughout body tissues. Vilanterol has a volume of distribution of approximately 3 liters/kg, while Fluticasone Furoate has a large volume of distribution due to its high tissue affinity.

Half Life

The half-life of Vilanterol is approximately 8 to 12 hours, allowing for once-daily dosing. Fluticasone Furoate has a longer half-life of approximately 24 hours, supporting once-daily administration.

Clearance

Vilanterol is primarily cleared through hepatic metabolism and renal excretion. Fluticasone Furoate is extensively metabolized in the liver, with its metabolites excreted mainly in the feces.
