Methods and compositions for the treatment of rhinosinusitis in a subject using topical verapamil.

Methods and compositions to treat and diagnose diseases or pathologies associated with inflammation of the sinuses and nasal cavity

Provided herein are, inter alia, methods for treating rhinosinusitis with P-glycoprotein inhibitors. A subject having rhinosinusitis is identified and then treated by administration to the subject an effective amount of a P-gp inhibitor. The subject having rhinosinusitis can be identified by one of skill in the art based on known methods, e.g., based on detection of the presence of symptoms, by endoscopy, or by computed tomography. The efficacy of the treatment can be monitored by methods known in the art, e.g., by monitoring symptoms, by endoscopy or computed tomography. The P-glycoprotein inhibitor can be delivered to the subject's nasal passage and sinuses by an inhalation device, by flushing, by spraying, or by an eluting implant surgically placed in the subject's nasal passage or sinuses. The P-glycoprotein inhibitor can also be administered in combination with one or both of a corticosteroid and an antibiotic.

Treatment of rhinosinusitis with P-glycoprotein inhibitors

A method of delivering a therapeutic agent into the central nervous system through the blood-brain barrier includes implanting an implant within the submucosal space of the olfactory epithelium. The implant can provide sustained drug delivery to the brain. The implant can be placed using a minimally invasive surgical approach.

Biodegradable implant for sustained trans-nasal delivery of therapeutic agents to the brain

Treatment of rhinosinusitis with p-glycoprotein inhibitors

Methods for identifying and optionally treating subjects, e.g., subjects who have Chronic Rhinosinusitis (CRS), based on the detection of elevated levels of soluble P-glycoprotein in nasal secretions. The methods of treatment can include administration of a therapeutically effective amount of a P-glycoprotein inhibitor.

Secreted P-glycoprotein is a non-invasive biomarker of chronic rhinosinusitis

Provided herein are, inter alia, methods for treating rhinosinusitis with P-glycoprotein inhibitors. A subject having rhinosinusitis is identified and then treated by administration to the subject an effective amount of a P-gp inhibitor. The subject having rhinosinusitis can be identified by one of skill in the art based on known methods, e.g., based on detection of the presence of symptoms, by endoscopy, or by computed tomography. The efficacy of the treatment can be monitored by methods known in the art, e.g., by monitoring symptoms, by endoscopy or computed tomography. The P-glycoprotein inhibitor can be delivered to the subject's nasal passage and sinuses by an inhalation device, by flushing, by spraying, or by an eluting implant surgically placed in the subject's nasal passage or sinuses. The P-glycoprotein inhibitor can also be administered in combination with a corticosteroid.

Provided are methods of delivering at least one pharmaceutical agent to the central nervous system (CNS) of a subject, methods of treating a neurological disorder or pain in a subject that include administering at least one pharmaceutical agent onto a SEM graft in the skull base of the subject. Also provided are methods of treating a neurological disorder or pain in a subject that include forming a SEM graft in the skull base of the subject and administering at least one pharmaceutical agent onto the SEM graft in the skull base of the subject. Also provided are methods of forming a SEM graft in the skull base of a subject, compositions for administration onto a SEM graft in the skull base or into an endonasal reservoir or endonasal reservoir device in a subject, and devices for administering such compositions onto a SEM graft in the skull base of a subject.
