Topical delivery of viscous medications for the treatment of diseases associated with chronic sinusitis
View Patent ↗A medication or combination of medications for the treatment of a disease involving the sinuses is incorporated into a sterile medical gel. The viscosity of the gel or the adhesion of the gel to the patient's sinus cavity allows the gel to be maintained in the cavity for a sufficient length of time for treatment of the affected area. This reduces the amount of wasted medication that would otherwise result from other topical methods.
1. A medicated gel, comprising:
a sterile viscous fluid having a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion; and
a medication dispersed in the sterile viscous fluid;
wherein the pH of the medicated gel is not adjusted by the addition of any acids, bases, or buffers, and the osmolality of the medicated gel is not adjusted by addition of any salts;
wherein the sterile viscous fluid comprises hydroxyethylcellulose, and the medication comprises tobramycin or mometasone.
2. The medicated gel of claim 1 , wherein the sterile viscous fluid has a viscosity between 2,000 centipoise and 128,000 centipoise at 20° C.
3. The medicated gel of claim 1 , wherein the medication further comprises an antimicrobial medication, an antibiotic medication, an anti-inflammatory medication, an anti-fungal medication, a mucolytic medication, an antihistamine medication, a decongestant medication, a vasoconstrictor medication, an anti-viral medication, a chelating agent medication, or an oncologic medication.
4. The medicated gel of claim 1 , wherein the medication further comprises a micro fine Vitamin D3 suspension.
5. A medical kit, comprising:
a syringe; and
a medicated gel disposed within the syringe;
wherein the medicated gel comprises a sterile viscous fluid having a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion and a medication dispersed in the sterile viscous fluid, the pH of the medicated gel is not adjusted by the addition of any acids, bases, or buffers, and the osmolality of the medicated gel is not adjusted by addition of any salts; and
wherein the sterile viscous fluid comprises hydroxyethylcellulose, and the medication comprises tobramycin or mometasone.
6. The medical kit of claim 5 , wherein the sterile viscous fluid has a viscosity between 2,000 centipoise and 128,000 centipoise at 20° C.
7. The medical kit of claim 5 , wherein the medication further comprises an antimicrobial medication, an antibiotic medication, an anti-inflammatory medication, an anti-fungal medication, a mucolytic medication, an antihistamine medication, a decongestant medication, a vasoconstrictor medication, an anti-viral medication, a chelating agent medication, or an oncologic medication.
8. The medical kit of claim 5 , wherein the medication further comprises a micro fine Vitamin D3 suspension.
9. A method of preparing a medicated gel, comprising:
dissolving a medication in a solvent;
forming a sterile gel; and
dispersing the dissolved medication in the gel to form the medicated gel;
wherein the medicated gel has a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion, the pH of the medicated gel is not adjusted by the addition of any acids, bases, or buffers, and the osmolality of the medicated gel is not adjusted by addition of any salts;
wherein the solvent comprises water or propylene glycol, and the medication comprises tobramycin or mometasone.
10. The method of claim 9 , wherein the medication further comprises a micro fine Vitamin D3 suspension.
11. A medicated gel, comprising:
a sterile viscous fluid having a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion; and
a medication dispersed in the sterile viscous fluid, wherein the sterile viscous fluid has a viscosity between 2,000 centipoise and 128,000 centipoise at 20° C.,
wherein the medication comprises an antimicrobial medication, an antibiotic medication, an anti-inflammatory medication, an anti-fungal medication, a mucolytic medication, an antihistamine medication, a decongestant medication, a vasoconstrictor medication, an anti-viral medication, a chelating agent medication, or an oncologic medication, wherein the sterile viscous fluid comprise hydroxyethylcellulose, and the medication comprises tobramycin or mometasone, and
wherein the medication further comprises a micro fine Vitamin D3 suspension; and
wherein the pH of the medicated gel is not adjusted by the addition of any acids, bases, or buffers, and the osmolality of the medicated gel is not adjusted by addition of any salts.
12. A medicated gel, consisting essentially of:
a sterile viscous fluid having a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion; and
a medication dispersed in the sterile viscous fluid;
wherein the sterile viscous fluid comprises hydroxyethylcellulose, and the medication comprises tobramycin or mometasone.
13. A medical kit, comprising:
a syringe; and
a medicated gel disposed within the syringe;
wherein the medicated gel consists essentially of a sterile viscous fluid having a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion and a medication dispersed in the sterile viscous fluid;
wherein the sterile viscous fluid comprise hydroxyethylcellulose, and the medication comprises tobramycin or mometasone.
14. A method of preparing a medicated gel, consisting essentially of:
dissolving a medication in a solvent;
forming a sterile gel; and
dispersing the dissolved medication in the gel to form the medicated gel;
wherein the medicated gel has a viscosity sufficient to be maintained within a human paranasal sinus cavity after insertion;
wherein the solvent comprises water or propylene glycol, and the medication comprises tobramycin or mometasone.
