Ritonavir

YARDLEY, Pa., June 27, 2024 (GLOBE NEWSWIRE) -- Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced that XHANCE® (fluticasone propionate) has been added to Express Scripts’ national formularies, including the National Preferred, Flex, and Basic formularies, among the largest commercial formularies in the U.S. with more than 24 million lives. “XHANCE is approved for treatment of chronic rhinosinusitis and, importantly, is the only medication approved for by far the most common type - without nasal polyps, so we are very pleased that Express Scripts has added XHANCE as a preferred option to these formularies,” said Ramy Mahmoud, MD, MPH, CEO of Optinose. “Our recently published landmark studies in chronic sinusitis, and the recent FDA approval, mark a breakthrough for doctors and patients who want safe and effective treatment for one the most common diagnoses in adult outpatient medicine. We look forward to seeing the addition of XHANCE to these Express Scripts national formularies result in increased patient access to the only evidence-based prescription treatment for this disease.” Chronic sinusitis (also referred as chronic rhinosinusitis) affects approximately 30 million adults in the United States. Research shows that the disease impairs quality of life to a similar degree as other serious chronic conditions, such as chronic obstructive pulmonary disease, sciatica, or migraine. The ReOpen clinical trial program was the first ever controlled trial program we are aware of to demonstrate significant improvement in both symptoms and inflammation inside the sinuses for patients with chronic sinusitis, regardless of whether nasal polyps are present, and to demonstrate significant reduction in the number of acute exacerbations.1 About OptinoseOptinose is a specialty pharmaceutical company focused on serving the needs of patients cared for by ear, nose and throat (ENT) and allergy specialists.

About XHANCEXHANCE is a drug-device combination product that uses the Exhalation Delivery System™ (also referred to as the EDS®) designed to deliver a topical steroid to the high and deep regions of the nasal cavity where sinuses ventilate and drain. XHANCE is approved by the U.S. Food and Drug Administration for both the treatment of chronic rhinosinusitis without nasal polyps (also called chronic sinusitis) and chronic rhinosinusitis with nasal polyps (also called nasal polyps) in patients 18 years of age or older. IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE. WARNINGS AND PRECAUTIONS: Local nasal adverse reactions, including epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing, can occur. Monitor patients periodically for signs of possible changes on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma until healing has occurred.Glaucoma and cataracts may occur with long-term use. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use XHANCE long-term.Hypersensitivity reactions (e.g., anaphylaxis, angioedema, urticaria, contact dermatitis, rash, hypotension, and bronchospasm) have been reported after administration of fluticasone propionate. Discontinue XHANCE if such reactions occur.Immunosuppression and infections can occur, including potential increased susceptibility to or worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infection; ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients.Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue XHANCE slowly.Assess for decrease in bone mineral density initially and periodically thereafter. ADVERSE REACTIONS: Chronic rhinosinusitis without nasal polyps: The most common adverse reactions (incidence ≥3%) are epistaxis, headache, and nasopharyngitis.Chronic rhinosinusitis with nasal polyps: The most common adverse reactions (incidence ≥3%) are epistaxis, nasal septal ulceration, nasopharyngitis, nasal mucosal erythema, nasal mucosal ulcerations, nasal congestion, acute sinusitis, nasal septal erythema, headache, and pharyngitis. DRUG INTERACTIONS: Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid effects.USE IN SPECIFIC POPULATIONS: Hepatic impairment. Monitor patients for signs of increased drug exposure.Please see full Prescribing Information, including Instructions for Use References James N. Palmer, Nithin D. Adappa, Rakesh K. Chandra, Greg E.
