Fluticasone Drug Review: PTCB Exam Prep Guide

Fluticasone Overview for Pharmacy Technicians

Fluticasone is a versatile corticosteroid available in multiple formulations for both respiratory and nasal conditions. Its popularity as both a prescription and OTC medication makes it a frequently tested drug on the PTCB certification exam.

Brand Names and Formulations

Fluticasone is available under several brand names depending on the formulation and salt form:

Flonase (fluticasone propionate nasal spray): OTC nasal spray for allergic rhinitis
Flovent HFA (fluticasone propionate inhaler): Prescription inhaled corticosteroid for asthma
Flovent Diskus: Dry powder inhaler formulation
Arnuity Ellipta (fluticasone furoate): Once-daily inhaled corticosteroid for asthma
Advair (fluticasone/salmeterol): Combination inhaler with a LABA
Breo Ellipta (fluticasone furoate/vilanterol): Once-daily combination for asthma and COPD

Drug Classification

Fluticasone is a synthetic corticosteroid. When inhaled, it is classified as an inhaled corticosteroid (ICS), which is the most effective long-term controller medication for persistent asthma. As a nasal spray, it is a nasal corticosteroid, the gold standard for allergic rhinitis treatment.

Mechanism of Action

Fluticasone works by binding to intracellular glucocorticoid receptors, reducing inflammation through multiple pathways: decreasing inflammatory cell migration, suppressing cytokine production, reducing mucus secretion, and decreasing airway hyperresponsiveness. The anti-inflammatory effect is local, minimizing systemic side effects when used as directed.

Common Indications

Asthma: Maintenance therapy for persistent asthma (inhaler form)
Allergic rhinitis: Treatment of nasal allergy symptoms (nasal spray)
COPD: In combination products for maintenance therapy

Important Side Effects

Nasal spray side effects:

Nosebleeds (epistaxis)
Nasal dryness and irritation
Headache

Inhaler side effects:

Oral thrush (candidiasis): Fungal infection of the mouth caused by steroid deposition in the oral cavity
Hoarseness (dysphonia): From steroid effects on the vocal cords
Sore throat

The key patient education point: rinse the mouth with water and spit after using an inhaled corticosteroid to prevent oral thrush. This is frequently tested on the PTCB exam.

Key Differences: Controller vs. Rescue

Inhaled corticosteroids like fluticasone are controller/maintenance medications used daily for prevention. They are not rescue inhalers and should never be used for acute asthma attacks. Patients must understand this distinction. Rescue inhalers (albuterol) are used for acute symptoms.

PTCB Exam Tips

Key facts: Flonase is the OTC nasal spray, Flovent is the prescription inhaler, inhaled corticosteroids are controller medications not rescue, patients must rinse mouth after use to prevent thrush, and Advair combines fluticasone with salmeterol (a LABA).
