an analgestc agent substanttally free or of tts R(-) antipode se~ected

BA~KGROUN~ OF THE~INVENT~ON
Inflammationt or the ~tnflammatory response~, is the result of '
lS complex interconnected physiological events, inciuding increased ~`
vascular permeabiltty, flutd accumulattons, and the migrat~on of a
-changing populat~on of inflammatory cells~into the inflamed area. The
clinical manifestations of lnflammat~ton ~include swelltng (edemaj, j`
increased local temperature, erythema, and patn. The inflammatary
response can be tr1ggered by any of a num:ber of causative factors,~
includtng certain bacteria, rad~ation, hypersensittvity to chemical
agents, arthrttts-llke condittons, and the ltke. The inflammatorg
response is generally believed to be a primary defense mechanism ~n
the body, but, unchecked, can become excess1ve and can result in
25 functional impairment. ~ ,~
The use of non-steroidal ant1-inflammatory, anti-pyrettc and
analgesic drugs,~especially thè salicylates~,~ which include aspirtn and~
açpirin derivatives,~ ~to combat inflammation~ and atten~Jant pain ts
accepted medtcal praftice. ~he non-steroidals are commonly employed~ I 30 to relieve pain and in~lammatton associated~with, for example, burslt-
is, arthritts, and the like.

feel1ngs o~ d1stress or suffer1ng caused by st1mulat10n of~spec1al1~ed
~5 ner~e endtngs.~A~gr~at variety o~f drugs~have~been developed to reduce

the brain. A~ong the latter group of dru~s that are designed to bloc~ -
the sensatton of paln~ are the analgesics, which generally re7ieve
pain without causing unconsciousness~ Analgesics can be further
classified into two main categories: opioid analgesics, including
morphine, codeine, levorphanol, and the morphine-like analgesics
meperidine, and methadone; and antipyretic analgesics, such as
aspirin, ibuprofen, phenacetin, acetaminophen, phenylbutazone, and '~
indomethacin. ~ ~ "
Although the precise pharmacolog1cal actton of these analgesics
I0 is uncertatn, there are certain effects whtch read~ly distinguish the
opioid analgesics from the antipyretics. In~particular, the; antipyre- r"~
tics are weak analgesics, with much of their ef~ect in the peripheral
nervous system, so that behavioral changes~ do not usually occur.
Generally, these analgestcs relieve only pain ortginating from~mus- '''
15 cles, joints, tendons and fasciae, and~ are ineffe'ctive against deep
visceral pain. However, the opioid~analgesics are quite effective
against all types of pain,~with broad-based' actton in the central ~'.'
nervous system. Aside from potent analgesta, the~opioids, also known Il"'
as narcottcs, often produce effects on mood and other behavioral
20 changes. Perhaps the most notable side effect of opioid analgesics ts L~'
the fact that their repeated use is assoclated with tolerance, as well~ ;'
as psychtc and phys~cal dependence.
Ibuprofen, or ~+)~ 2-(p-isobutylphenyl)propionic acid, is
well-known as a nonsteroidal ant~-inflammatory ~drug hav1ng analgestc; 'i
25 and anttpyretic activity. Ib~profen is curre~ntly marketed by~ L"~""'
~prescriptton in the United States generically, as ;well as~ under ~'
t`radenames such;~as Mot~rln-, which i~s~ avallable ln 400, 600 and~ 800 mg '~"

available in this country in non-prescription strength (200~ ~g); under~
30 ' a variety of tlradenames, including Advil and Nuprin~, as well as in
~` generic form.~ For the treatment~of mild~t moderate pa~in, 400 mg

Various oral dosage forms can be used, including such solid forms
as tablets, gelcaps capsules, granules, lozenges and bulk powders and ;'
liquid forms such as syrups and suspensions. These oral forms com-
prise a safe an~ effectiYe amount, usually at least about 5% of the 1;
active component. Solid oral dosa~e forms preferably contain from ~-
about 5% to about g5%, more preferably fro- about l0% to about 95%t
and most preferably from about 25% to about 95X of the active compo- ;'`
nent. Ltquid oral dosage forms preferably contaln from about 1% to
about 50~t and more preferably from about 1% to about 25% and most
preferably ~rom about 3%~to about 10% of the active compo'nent. ~''
~ablets can be compressed, tablet trtturates, enteric-coated, ~"
sugar-coated, film-coated or multiple compressed, containing suitable '~
binders, lubrican~s, diluents, disintegrating agents, coloring agents,
Slavoring agents, preservattves and flow-inducing agents. "
L~qu1d oral dosage fonms include aqueous and nonaqueous solu-
tions, emulsions, suspensions, and solutions~ and~or suspensions
reconstituted from non-effervescent granules, containing suitable ~
20 solvents, preservat1ves, emulsifying agents, suspending ~agentst ~!,
diluents, sweeteners, taste-masking agents, coloring agents, and
flavoring agents. SpeciSic examples ~of pharmaceutically acceptable
carrters and excipients that may ~be used to formulate oral dosage
forms, are described in U.S. Patent 3,903,2g7, Robert, issued' Sep-~
tember 2, 1975, incorporated by reference~herein. Techniques and~ -`
compositions for making solid oral dosage forms are described in
Marshall, ~Solid Oral Dosage Fonms,~ Mod'ern Phanmaceutics, ~ ,
`(Banker and Rhodes, editors), 359-427 (1979), incorporated by refer~

In preparing~the ltquid~oral dosage;forms,~ the actlve~component
is incorporated~1nto an aqueous-based ora~lly~acceptable~ph~armaceut1cal
'~5 carrier consistent ~with conYentional pharmaceutical pract1ees~. An
'aqueaus-based orat~y~acceptable ;phar~aceutical carrier~ is one~
~` `wherein the entire or predomtnant ~solvent content is water. Typical ~ 0

carriers include simple aqueous soiutions, syrups, dispersions and
suspensions, and aqueous based emulsions such as the oil-in-water
type. The most preferred carrier ~s a suspension of the pharma-
ceutical composition in an aqueous vehicle containing a suitable
suspending agent. Suitable suspending agents include Avicel RC-S91 (a `
microcrystalline cellulose/sodium carboxymethyl cellulose mixture
ava~lable from FM~), guar gum~and the 11ke. ~Such suspending agents
are well known to those skilled ~n thè art. ~hile the a~ount of water
in the compositions of th~s invention can vary over~quite a wide range
depending upon the total weight and volume of~the act~ve component and
other optional non-actiYe~ingred1ents, the total water content, based
on the weight of the~final composit10n,~ will~:generally range from 2
about 20 to about 75%, and, preferably, fro~ about 20 to about 40X, by
weight/volume.
Although water itself may make ~up the entire carrier, typical
liquid formulations ;preferably contain a co-solvent, for example, ~'
propylene glycol, glycerin, sorbitol~solution and the like, to assist
solubilization and incorporation of water-insoluble ingredients, such
as flavoring oils and the like into the composition. In general,
20 therefore, the compositlons of thts invention preferably contain from
about 5 to about 25 volume/volume percént and, most preferably, fro~
about 10 to about 20 volume/ volume per~ent, of the co-solvent.
rhe compositions of this invention ma~ optionally contatn one or
more other known therapeutic agents, particularly those commonly
25 utilized in cough~cold preparations, such~as, for exàmple, a cough
