Peptide for preventing hearing loss, and composition comprising same
The present invention relates to a pharmaceutical composition for preventing and treating hearing loss. More particularly, the present invention relates to a composition including a telomerase-derived peptide, the composition being effective in the treatment and prevention of hearing loss due to an ototoxic drug. A peptide having a sequence of SEQ ID NO: 1, a peptide having 80% or more sequence homology to the sequence, or a fragment thereof, according to the present invention, has an excellent effect in the treatment and prevention of hearing loss due to an ototoxic drug.
1. A method of treating hearing loss comprising:
administering an effective amount of a composition comprising the isolated peptide of SEQ ID NO: 1 to a subject in need thereof, wherein the hearing loss is caused by administration of an ototoxic drug or ototoxic drug treatment, and wherein the ototoxic drug is one or more drug selected from the group consisting of aminoglycoside-based antibiotics and diuretics.
2. The method of claim 1 , wherein the aminoglycoside-based antibiotics comprise kanamycin, and the diuretics comprise furosemide.
3. The method of claim 1 , wherein the composition is a pharmaceutical composition further comprising a pharmaceutically acceptable additive.
4. The method of claim 3 , wherein the pharmaceutically acceptable additive is a diluent, an excipient, a lubricant, a binder, a disintegrant, a buffer, a dispersant, a surfactant, a colorant, a flavoring, or a sweetener.
5. The method of claim 1 , wherein the pharmaceutical composition is administered orally, intrarectally, percutaneously, intravenously, intramuscularly, intraperitoneally, intramedullary, intradurally, or subcutaneously.
6. The method of claim 1 , wherein the pharmaceutical composition is a tablet, a pill, a soft or hard capsule, a granule, powder, a liquid preparation, or an emulsion.
7. The method of claim 1 , wherein the pharmaceutical composition is an injection, a dripping agent, a lotion, an ointment, a gel, a cream, a suspension, an emulsion, a suppository, a patch, or a spraying agent.
8. The method of claim 1 , wherein the isolated peptide of SEQ ID NO: 1 is administered at a dose of from 10 ng/kg/day to 100 g/kg/day.
9. The method of claim 1 , wherein the isolated peptide of SEQ ID NO: 1 is administered at a dose of from 2μg/kg/day to 100 mg/kg/day.
10. The method of claim 1 , wherein pharmaceutical composition is administered once to three times daily.
11. A method of preventing hearing loss caused by administration of an ototoxic drug or ototoxic drug treatment comprising:
administering an effective amount of a composition comprising the isolated peptide of SEQ ID NO: 1 to a subject in need thereof, wherein the ototoxic drug is an aminoglycoside-based antibiotic.
12. The method of claim 11 , wherein the aminoglycoside-based antibiotics comprise antibiotic comprises kanamycin.
13. The method of claim 11 , wherein the composition is a pharmaceutical composition further comprising a pharmaceutically acceptable additive.
14. The method of claim 11 , wherein the pharmaceutical composition is administered orally, intrarectally, percutaneously, intravenously, intramuscularly, intraperitoneally, intramedullary, intradurally, or subcutaneously.
15. The method of claim 11 , wherein the pharmaceutical composition is a tablet, a pill, a soft or hard capsule, a granule, powder, a liquid preparation, or an emulsion.
16. The method of claim 11 , wherein the pharmaceutical composition is an injection, a dripping agent, a lotion, an ointment, a gel, a cream, a suspension, an emulsion, a suppository, a patch, or a spraying agent.
17. The method of claim 11 , wherein the isolated peptide of SEQ ID NO: 1 is administered after the ototoxic drug or ototoxic drug treatment.
