s The present invention relates to compositions and methods for providing
improved tre~t~n~, management or mitig~tion of cold, cold-like and/or fiu
symptoms by q,~minictering a safe and effective amount of a composition comprising
certain amino acid salts of propionic acid non-steriodal anti-infl-q- ...n~to,y agents
along with at least one of (a) a deconge~ , (b) an expectorant, (c) an
0 ~ntihictqmine, and (d) an qntit--csive~
BACKGROUND OF THE INVENTION
The co~ llon cold, -q-lthollgh not usually a serious illness, is a highly pre-
valent, discou~- Iu~g and annoying infli~ior- The terrn ~cGI.. on cold~ is applied
to minor respiratory illnesses caused by a variety of di~e~ r~yualo~y viruses.
5 While rhinoviruses are the major known cause of common colds, nc~.~,l;~ for
appl o~ tely 30 percent of colds in adults, viruses in several other groups are also
impor~ant. While immllne responses occur, and infçctiol- vith some l~piratory
tract viruses th~.efole could be p~enled by a vaccine, dc~elop,~ of a polytypic
vaccine to cover all possible agents is ;ll~pra~lical~ Thus, the problem of controlling
20 acute upper r~sp;,~lol~ disease plesenls complex chqll~ng~s, and the long-desired
discovery of a single cure for the collu~on cold is an unrealistic c~l~e~ t;~n
Early ~mp~ol-ls may be minimql uith only mild mqlqi~., sore throat and
n_sal compl_ints. ~lth rhinovirus infection, a~ G~Ils of nasal dischal~e, nasal
co~P~lion, qnd ~.~e~-:ng usually c~ e -r.C on the first day of illness _nd progress
2s to m-q-Yimum severity by the second or third day. Along with nasal symptoms may
come sore, dry or scla~chy throat and ho~,~ess and cough. Other symptoms may
include mild bun~ing of the eyes, loss of smell and taste, a feeling of pressure or
fullness in the sinuaes or ears, headache and vocal illlpaulllelll. Fever can occur,
but is un~iouu,lon. Tnfluen~ infection generally includes fever, often of sudden30 onset and pe.a;all. g for several days, and with great severity; generalized aches and
pains; fatigue and wÇ~Icness; and chest discon~. l.
At present, only symptomatic ~ is available for the common cold.
The costs oftreating colds with over-the-counter ~.P~iC~l;or~C in the United States is
çstim~ted at an annual cost of over 1.5 billion dollars. The direct costs of llc<.l~
3s in outpatient clinics is estim~ted at almost four billion dollars. Indirect costs, based
on the amount of loss in wages because of restricted activity are subst~nti~ny
higher.

non-steroidal anti-inllz~.. ~tory agents may also be employed. Of these propionic
acid NSAIDs, ibuprofen, napro~en and ketoprofen are most pl~f~.l~.
Most pr~fel,~d for use herein is the S(+) isomer of these NSAID salts. The
s term "S(+)" as applied to the qnqlgesic agents herein is int~n~ed to encomrqcs the
d~ ivrvtato~y or S(+) isomer of the amino acid salt derivatives thereof. The
e,.~, essivn "sl~b~ ;911y free of the R(-) antipode" as used in con~unction vith the
term "S(+)~ means that the S(+) enantiomer is sufficiently free it is R(-) antipode to
exert the desired onset-hq~tene~ and enhqnced q-nq-lgesic effect. Practically
20 spe~ing this means that the active ingredient should contain at least 90% by
weight of the S(+) enantiomer and 10% or less weight R(-) enantiomer. Preferably,
the weight ratio of S(+) enantiomer to R(-) enantiomer is greater than 20:1, more
preferably greater than 97:3. Most preferably the S(+) enantiomer is 99 or more /o
by weight free of R(-) çnqntiomer, i.e., the weight ratio of S to R is appro~l5a~

Avicel RC-591 (a microcrystalline-cellulose/sodium carboxymethyl cellulose
mixture available from FMC), guar gum and the like Such suspending agents are
well known to those skilled in the art While the amount of water in the
compositions of this invention can vary over quite a wide range depending upon the
s total weight and volume of the active component and other optional non-active
ingredients, the total water content, based on the weight of the f~nal composition,
will generally range from about 20 to about 75%, and, preferably, from about 20 to
about 40%, by weight/volume.
tho~lgh water itself may make up the entire carrier, typical liquid formu-
o lations preferably contain a co-solvent, for e~ .le, propylene glycol, glycerin, sor-
bitol solution and the like, to assist solubili7~ti~n and incorporation of
water-insoluble ingre~ nts~ such as flavoring oils and the like into the ccs...pos;lion.
In general, ther~fore, the co",pos;lions of this invention p~ft;lably contain from
about 5 to about 25 volume~volume percent and, most pref.,.~bly, from about 10 to
lS about 20 volume/ volume ~rcenl, of the co-solvent.
The compositio~c of this invention may optionally contain one or more other
known therapeutic agents, particularly those ~..~ or.l~ utilized in cough/cold
prepalations~ such as, for exarnple, a s ~ol~cl~o~ tor such as terbutaline,
a.,fi.loph~lline, ep,~epLIne, isopre,1aline"~etap,oterenol, bitoterol, theoph"rlline and
20 albuterol as well as other analgesic agents such as r~~ sphell and aspirin. Ahighly prer~ d optional cc ~ronenl is c~ e Other optional inglcl;c~lls well
known to the ph~ll.zcist's art may also be inrl~dGd in ~ mtc generally known forthese ingredients, for cAample, natural or ~liLcizl ,~.~ten~,.s, flavolii1g agents,
colorants and the like to provide a palatable and ~ c~nt looking f~nal product,
2s antioxidants, for example, butylated hydroAy anisole or bul~laled l.~droA~ toluene,
and preservatives, for e~ nple methyl or propyl p&~,n or sodium ben,oate, to
prolong and çnh~nr~ shelf lilfe.
METHOD OF TREATMENT
The ~mount of the ~ha... ~r~ltir~l co"lpos;lion ~ ,(e..,d depends upon
30 the percent of active ingredients within its formula, which is a function of the
~mol~nt of the n~pl.ll.al~ derivative and any optional co",pone.lts such as a
de~ongest~nt cough s~pln~lt7 eA~lolanl and/or ~ntih.~;....;..e required per
dose, stability, release characteristics and other pharm~c~utic~l pa,~..~lers
Usually from about 1 mg/kg to about S0 mg/kg per day, preferably from
3s about 2 mg/kg to about 30 mg/kg per day and most plefe.ably from about 3 mglkg
per day to about 20 mg/kg per day of the ph~ ...~ceutical co"~pos;lion is
a~lminictered as des~,libed herein. This amount can be given in a single dose, or,

wo 95/07103 ~
. %~ 8
preferably, in multiple (two to six) doses repeatedly or sustained release dosages
over the course of treatment. Generally, each individual dosage of the pharma-
ceutical compositions of the present invention range ~om about I mg/kg to about
25 mg/kg, preferably from about 2 mgAcg to about 15 mgQcg and most preferably
s from about 3 mglkg to about 10 mg/kg. While dosages higher than the foregoing
are effective to provide relief from cough, cold-like, flu and flu-like syrnptoms, care
must be taken, as with any drug, in some individuals to prevent adverse side effec~.
