Abstract
Therapy for influenza using a combination of a neuraminidase inhibitor, a macrolide antibiotic, and a non-steroidal anti-inflammatory drug has been found to provide improved clinical outcomes and reduced incidence of viral quasispecies compared to conventional treatment with neuraminidase inhibitors alone. Effective treatment schedules are also provided. The drug combination can be used in concert with a proton-pump inhibitor and/or an additional antibacterial antibiotic.

A composition for treating infection with an influenza virus, comprising:
- a neuraminidase inhibitor;
- a macrolide antibiotic;
- and
- a non-steroidal anti-inflammatory drug.
The composition of claim 1, wherein the neuraminidase inhibitor is selected from the group consisting of ethyl (3R,4R,5S)-5-amino-4-acetamido-3-(pentan-3-yloxy)-cyclohex-1-ene-1-carboxylate (oseltamivir), 4S,5R,6R)-5-acetamido-4-carbamimidamido-6-[(1R,2R)-3-hydroxy-2-methoxypropyl]-5,6-dihydro-4H-pyran-2-carboxylic acid (laninamivir), (2R,3R,4S)-4-guanidino-3-(prop-1-en-2-ylamino)-2-((1R,2R)-1,2,3-trihydroxypropyl)-3,4-dihydro-2H-pyran-6-carboxylic acid (zanamivir), and (1S,2S,3S,4R)-3-[(1S)-1-acetamido-2-ethyl-butyl]-4-(diaminomethylideneamino)-2-hydroxy-cyclopentane-1-carboxylic acid (peramivir).
The composition of claim 1, wherein the macrolide antibiotic is selected from the group consisting of azithromycin, clarithromycin, erythromycin, fidaxomycin, telithromycin, carbomycin A, josamycin, kitamycin, midecamycin, midecamycin acetate, oleandomycin, solithromycin, spiramycin, troleandomycin, and roxithromycin.
The composition of claim 1, wherein the non-steroidal anti-inflammatory drug is selected from the group consisting of acetylsalicylic acid, diflunisal, ibuprofen, dexibuprofen, naproxen, indomethacin, tolmetin, sulindac, piroxicam, meloxicam, tenoxicam, mefenamic acid, meclofenamic acid, celecoxib, rofecoxib, valdecoxib, nimesulide, clonixin, licofelone, and flufentamic acid.
The composition of claim 1, further comprising a proton-pump inhibitor.
The composition of claim 5, wherein the proton-pump inhibitor is selected from the group consisting of omeprazole, lansoprazole, dexlansoprazole, pantoprazole, rabeprazole, and ilaprazole.
The composition of claim 1, further comprising an anti-bacterial antibiotic that is not the macrolide antibiotic.
The composition of claim 7, wherein the anti-bacterial antibiotic is selected from the group consisting of a penicillin, a penicillin in combination with a penicillinase inhibitor, a cephalosporin, a polymyxin, a rifamycin, a lipiarmycin, a quinolone, a sulfonamide, a lincosamide, a tetracycline, an aminoglycoside, a cyclic lipopeptide, a glycylcline, an oxazolidinone, and a lipiarmycin.
A method of treating an infection with an influenza virus, comprising:
- providing a neuraminidase inhibitor, a macrolide antibiotic, and a non-steroidal anti-inflammatory drug;
- and
- administering the neuraminidase inhibitor, the macrolide antibiotic, and the non-steroidal anti-inflammatory drug to an individual on a schedule effective in reducing mortality due to influenza.
The method of claim 9, wherein the schedule comprises administering the composition for a first period of time followed by administration of the neuraminidase inhibitor for a second period of time.
The method of claim 9, wherein the macrolide antibiotic is selected from the group consisting of azithromycin, clarithromycin, erythromycin, fidaxomycin, telithromycin, carbomycin A, josamycin, kitamycin, midecamycin, midecamycin acetate, oleandomycin, solithromycin, spiramycin, troleandomycin, and roxithromycin.
The method of claim 9, wherein the non-steroidal anti-inflammatory drug is selected from the group consisting of acetylsalicylic acid, diflunisal, ibuprofen, dexibuprofen, naproxen, indomethacin, tolmetin, sulindac, piroxicam, meloxicam, tenoxicam, mefenamic acid, meclofenamic acid, celecoxib, rofecoxib, valdecoxib, nimesulide, clonixin, licofelone, and flufentamic acid.
The method of claim 9, further comprising a step of administering a proton-pump inhibitor.
The method of claim 13, wherein the proton-pump inhibitor is selected from the group consisting of omeprazole, lansoprazole, dexlansoprazole, pantoprazole, rabeprazole, and ilaprazole.
The method of claim 9, further comprising a step of administering an anti-bacterial antibiotic that is not the macrolide antibiotic.
The method of claim 15, wherein the anti-bacterial antibiotic is selected from the group consisting of a penicillin, a penicillin in combination with a penicillinase inhibitor, a cephalosporin, a polymyxin, a rifamycin, a lipiarmycin, a quinolone, a sulfonamide, a lincosamide, a tetracycline, an aminoglycoside, a cyclic lipopeptide, a glycylcline, an oxazolidinone, and a lipiarmycin.
A kit for treating disease resulting from infection with an influenza virus, comprising:
- a neuraminidase inhibitor;
- a macrolide antibiotic;
- a non-steroidal anti-inflammatory drug;
- and
- instructions for administering the neuraminidase inhibitor, the macrolide antibiotic, and the non-steroidal anti-inflammatory drug to an individual on a schedule effective in reducing mortality due to influenza, wherein the schedule comprises administering the neuraminidase inhibitor, the macrolide antibiotic, and the non-steroidal anti-inflammatory drug for a first period of time followed by administration of only the neuraminidase inhibitor for a second period of time.
The kit of claim 17, wherein the macrolide antibiotic is selected from the group consisting of azithromycin, clarithromycin, erythromycin, fidaxomycin, telithromycin, carbomycin A, josamycin, kitamycin, midecamycin, midecamycin acetate, oleandomycin, solithromycin, spiramycin, troleandomycin, and roxithromycin, and wherein the non-steroidal anti-inflammatory drug is selected from the group consisting of acetylsalicylic acid, diflunisal, ibuprofen, dexibuprofen, naproxen, indomethacin, tolmetin, sulindac, piroxicam, meloxicam, tenoxicam, mefenamic acid, meclofenamic acid, celecoxib, rofecoxib, valdecoxib, nimesulide, clonixin, licofelone, and flufentamic acid.
