Patient With MG-Related Ptosis Successfully Treated With Nasal Spray Duo
Although further research is needed, these new findings suggest that using the 2 intranasal sprays is an effective option for patients with myasthenia gravis (MG) who experience eyelid drooping.
For the first time, data have shown improvements in upper eyelid drooping resulting from

“This case is particularly noteworthy due to the rapid relief and ease of application, suggesting these treatments as potential alternatives or adjuncts in MG management,” wrote the researchers, noting that current treatments, including prolonged immunosuppressive therapy and pyridostigmine, carry significant adverse effects. “Further studies with larger patient populations and controlled settings are necessary to clarify the use of oxymetazoline and flunisolide intranasal sprays for ptosis, specifically in relation to MG, and to explore their mechanism of action, long-term efficacy, and safety profile.”
Use of these 2 sprays was implemented for a 71-year-old woman who presented to the emergency department following 3 weeks of ptosis in the left eye, as well as issues with swallowing. The patient was initially started on 3 sprays of oxymetazoline hydrochloride 0.05% per nostril followed by 2 sprays per nostril twice daily before stopping on the third day to alleviate rebound congestions. She then was given 2 sprays of flunisolide per nostril twice daily for 7 days. Between treatments, the patient received nasogastric tube insertion due to dysphagia.
Symptoms resolved on the fifth day, with complete resolution of the ptosis, and on the seventh day, the tube was removed with complete resolution of dysphagia. The group noted that sequential use of these 2 sprays left them unable to determine which spray contributed more to symptom resolution.

The group noted that there remain unknowns about the mechanisms underlying the relief of ocular symptoms from intranasal sprays.
“Although significant absorption through the nasolacrimal system is unlikely due to gravity, the upward force exerted by spray bottles and some retrograde flow via nasolacrimal cilia may make it plausible,” wrote the researchers. “Another possibility lies in the therapeutic benefits of systemic absorption, likely due to vasoconstrictive effects improving muscle tone. It is crucial to acknowledge that there have been only transient side effects of flunisolide such as nasal stinging and throat irritation. Considering the systemic absorption of lipophilic drugs like oxymetazoline, potential adverse effects include increased nasal congestion, impaired vision, fast or irregular heartbeat, hypertension, and dizziness.”
