What Brufen SR is

used for

Brufen SR relieves pain and

reduces inflammation (swelling or

redness) that may occur:

in different types of arthritis

including rheumatoid

arthritis, osteoarthritis and

juvenile rheumatoid arthritis

in muscle and bone injuries

such as sprains, strains,

low back pain (lumbago),

rheumatism, and tendonitis,

such as tennis elbow

Brufen SR also relieves fever (high


Although Brufen SR can relieve the

symptoms of pain and inflammation,

it will not cure your condition.

Brufen SR contains the active

ingredient ibuprofen. Ibuprofen

belongs to a group of medicines

called non-steroidal anti-

inflammatory drugs (or NSAIDs).

How long to take it

Page 3 of 5

Do not take Brufen SR for longer

than your doctor says.

Depending on your condition, you

may need Brufen SR for a few days,

a few weeks or for longer periods.

As with other NSAID medicines, if

you are taking Brufen SR for

arthritis, it will not cure your

condition but it should help to

control pain, swelling and stiffness.

It usually begins to work within a

few hours but several weeks may

pass before you feel the full effects

of the medicine. If you have

arthritis, Brufen SR should be taken

every day for as long as your doctor


For menstrual cramps (period pain),

Brufen SR is usually taken at the

first sign of pain or menstrual

bleeding (whichever comes first).

Treatment should be continued for a

few days until the pain goes away.

4. Clinical Particulars


Therapeutic indications

Rheumatoid arthritis


Juvenile rheumatoid arthritis

Primary dysmenorrhoea


Brufen SR is also indicated for the relief of acute and/or chronic pain states in which there is an

inflammatory component.


Dose and method of administration

After assessing risk/benefit ratio in each individual patient, the lowest effective dose for the shortest

duration should be used.



The recommended daily dosage is two Brufen SR tablets taken as a single dose, preferably in the

early evening, well before retiring to bed. The tablets should be swallowed whole with plenty of


In severe or acute conditions, the total daily dosage may be increased to three tablets taken as two

tablets in the early evening and an additional tablet in the morning.

Page 2 of 12

Maintenance dose

In all indications the dose should be adjusted for each patient and the smallest dose that results in

acceptable control of the symptoms employed. In general, patients with rheumatoid arthritis and

osteoarthritis tend to require higher doses than patients with other conditions.

Special populations


In elderly patients receiving 600 - 1,200 mg daily ibuprofen appeared to be well tolerated. However,

since elderly patients may have a degree of impaired liver or renal function the adult dosage should

be used with caution.

Hepatic impairment

Ibuprofen should be used with caution in patients with impaired liver function (see section 4.4).

Renal impairment

Ibuprofen should be used with caution in patients with impaired renal function (see section 4.4).


Brufen SR is not recommended for children under 12 years.

Method of administration

The dose may be taken on an empty stomach. It is recommended that patients with sensitive

stomachs take ibuprofen with food.

Take Brufen SR tablets with plenty of fluid. Brufen SR tablets should be swallowed whole and not

chewed, broken, crushed or sucked on, to avoid oral discomfort and throat irritation.



Known hypersensitivity to ibuprofen or any of the inactive ingredients (see section 6.1).

Hypersensitivity (e.g. asthma, rhinitis or urticaria) to aspirin or other nonsteroidal anti-

inflammatory drugs.

History of gastrointestinal bleeding or perforation, related to previous NSAID therapy.

History of ulcerative colitis, Crohn’s disease, recurrent peptic ulceration or gastrointestinal

hemorrhage (defined as two or more distinct episodes of proven ulceration or bleeding).

Severe heart failure (NYHA IV)

Severe liver failure.

Severe renal failure (glomerular filtration below 30 mL/min).

Conditions involving an increased tendency or active bleeding.

During the third trimester of pregnancy.


Special warnings and precautions for use

General precautions

Prolonged use of any painkillers may induce headaches, which must not be treated with increased

doses of the painkillers, including ibuprofen.

Through concomitant consumption of alcohol, NSAID-related undesirable effects, particularly those

that concern the gastrointestinal tract or the central nervous system, may be increased on use of


Cardiovascular thrombotic events

Clinical studies suggest that use of ibuprofen, particularly at a high dose (2400 mg/day) may be

associated with an increased risk of arterial thrombotic events (for example myocardial infarction or

Page 3 of 12

stroke). Overall, epidemiological studies do not suggest that low dose ibuprofen (≤ 1200 mg/day) is

associated with an increased risk of arterial thrombotic events.

Patients with uncontrolled hypertension, congestive heart failure (NYHA II-III), established ischaemic

heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated

with ibuprofen after careful consideration and high doses (2400 mg/day) should be avoided.

Careful consideration should also be exercised before initiating treatment of patients with risk factors









particularly if high doses of ibuprofen (2400 mg/day) are required.

There is no consistent evidence that the concurrent use of aspirin mitigates the possible increased

risk of serious cardiovascular thrombotic events associated with NSAID use.


NSAIDs may lead to onset of new hypertension or worsening of pre-existing hypertension and

patients taking antihypertensives with NSAIDs may have an impaired anti-hypertensive response.

Caution is advised when prescribing NSAIDs to patients with hypertension. Blood pressure should

be monitored closely during initiation of NSAID treatment and at regular intervals thereafter.

Heart failure

Fluid retention and oedema have been reported in association with ibuprofen, therefore, the

medicine should be used with caution in patients with a history of heart failure or hypertension.

Gastrointestinal events

Ibuprofen should be used with extreme caution, and at the lowest effective dose, in patients with a

history of gastrointestinal haemorrhage or ulcer since their condition may be exacerbated.

All NSAIDs can cause gastrointestinal discomfort and serious, potentially fatal gastrointestinal

effects such as ulcers, bleeding and perforation which may increase with dose or duration of use,

but can occur at any time without warning. Upper GI ulcers, gross bleeding or perforation caused by

NSAIDs occur in approximately 1% of patients treated for 3-6 months and in about 2-4% of patients

treated for one year. These trends continue with longer duration of use, increasing the likelihood of

developing a serious GI event at some time during the course of therapy. However, even short term

therapy is not without risk.

Combination therapy with protective agents (e.g. misoprostol or proton pump inhibitors) should be

considered for these patients, as well as patients requiring concomitant low dose aspirin, or for other

drugs likely to increase gastrointestinal risk (see section 4.5).

The concomitant administration of ibuprofen and other NSAIDs, including cyclooxygenase-2 (Cox-

2) selective inhibitors, should be avoided due to the increased risk of ulceration or bleeding (see

section 4.5).

Caution is advised in patients with risk factors for gastrointestinal events who may be at greater risk

of developing serious gastrointestinal events, e.g. the elderly, those with a history of serious

gastrointestinal events, smoking and alcoholism. When gastrointestinal bleeding or ulcerations occur

in patients receiving NSAIDs, the drug should be withdrawn immediately. Doctors should warn

patients about signs and symptoms of serious gastrointestinal toxicity.

Caution should be exercised in patients receiving concomitant medication which could increase the

risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective

serotonin re-uptake inhibitors or antiplatelet drugs such as aspirin (see section 4.5).

The concurrent use of aspirin and NSAIDs also increases the risk of serious gastrointestinal adverse


Page 4 of 12

Severe skin reactions

NSAIDs may very rarely cause serious cutaneous adverse events such as exfoliative dermatitis,

toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS), which can be fatal and

occur without warning. These serious adverse events are idiosyncratic and are independent of dose

or duration of use. Patients should be advised of the signs and symptoms of serious skin reactions

and to consult their doctor at the first appearance of a skin rash or any other sign of hypersensitivity.

In exceptional cases, varicella can be at the origin of serious cutaneous and soft tissue infectious

complications. To date, the contributing role of NSAIDs in the worsening of these infections cannot

be ruled out. Thus, it is advisable to avoid use of ibuprofen in case of varicella.

Infections and infestations

Exacerbation of skin infection-related inflammations (e.g. development of necrotising fasciitis)

coinciding with the use of NSAIDs has been described. If signs of an infection occur or get worse

during use of Ibuprofen the patient is therefore recommended to go to a doctor without delay.

Respiratory disorders

Caution is required if ibuprofen is administered to patients suffering from, or with a previous history

of bronchial asthma, chronic rhinitis or allergic diseases since ibuprofen has been reported to cause

bronchospasm, urticarial or angioedema in such patients.

Ophthalmological effects

Adverse ophthalmological effects have been observed with NSAIDs; accordingly, patients who

develop visual disturbances during treatment with ibuprofen should have an ophthalmological


Impaired liver function or a history of liver disease

Patients with impaired liver function or a history of liver disease who are on long term ibuprofen

therapy should have hepatic function monitored at regular intervals. Ibuprofen has been reported to

have a minor and transient effect on liver enzymes.

Severe hepatic reactions, including jaundice and cases of fatal hepatitis, though rare, have been

reported with ibuprofen as with other NSAIDs. If abnormal liver tests persist or worsen, or if clinical

signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g.

eosinophilia, rash, etc.), ibuprofen should be discontinued.

Impaired renal function

Caution should be used when initiating treatment with ibuprofen in patients with considerable

dehydration. There is a risk of renal impairment especially in dehydrated children and adolescents.

The two major metabolites of ibuprofen are excreted mainly in the urine and impairment of renal

function may result in their accumulation. The significance of this is unknown. NSAIDs have been

reported to cause nephrotoxicity in various forms; interstitial nephritis, nephrotic syndrome and renal

failure. In patients with renal, cardiac or hepatic impairment, those taking diuretics and ACE

Inhibitors, and the elderly, caution is required since the use of NSAIDs may result in deterioration of

renal function.

The long term concomitant intake of various analgesics further increases the risk. For patients with

renal, hepatic or cardiac impairment, use the lowest effective dose, for the shortest possible duration

and monitor renal function especially in long term treated patients.











inflammatory drugs and thiazide diuretics

The use of an ACE inhibiting drug (ACE-inhibitor or angiotensin receptor antagonist, an anti-

inflammatory drug (NSAID or COX-2 inhibitor) and thiazide diuretic at the same time increases the

Page 5 of 12

risk of renal impairment. This includes use in fixed-combination products containing more than one

class of drug. Combined use of these medications should be accompanied by increased monitoring

of serum creatinine, particularly at the institution of the combination. The combination of drugs from

these three classes should be used with caution particularly in elderly patients or those with pre-

existing renal impairment.

Aseptic meningitis

Aseptic meningitis has been reported only rarely, usually but not always in patients with systemic

lupus erythematosus (SLE) or other connective tissue disorders.

Haematological monitoring

Blood dyscrasias have been rarely reported. Patients on long term therapy with ibuprofen should

have regular haematological monitoring.

Coagulation defects

Like other NSAIDs, ibuprofen can inhibit platelet aggregation. Ibuprofen has been shown to prolong

bleeding time (but within the normal range), in normal subjects. Because this prolonged bleeding

effect may be exaggerated in patients with underlying haemostatic defects, ibuprofen should be used

with caution in persons with intrinsic coagulation defects and those on anti-coagulation therapy.

Masking signs of infection

As with other drugs of this class, ibuprofen may mask the usual signs of infection.

Withdrawal of concomitant steroid therapy

In order to avoid exacerbation of disease or adrenal insufficiency, patients who have been on

prolonged corticosteroid therapy should have their therapy tapered slowly rather than discontinued

abruptly when ibuprofen is added to the treatment program.


Interaction with other medicines and other forms of interaction


Care should be taken in patients treated with anti-coagulants, such as warfarin, due to an enhanced

effect of anti-coagulants.

Concurrent use of NSAIDs and warfarin has been associated with severe sometimes fatal

haemorrhage. The mechanism of this interaction is not known but may involve increased bleeding

from NSAID-induced gastrointestinal ulceration or an additive effect of NSAID inhibition of platelet

function with the anticoagulant effect of warfarin.

Brufen SR should only be used in patients taking warfarin if absolutely necessary. Patients taking

this combination must be closely monitored.

Anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs)

Increased risk of gastrointestinal bleeding.


NSAIDs may decrease the excretion of aminoglycosides.


Ibuprofen has been shown to decrease the renal clearance and increase plasma concentrations of


Lithium plasma concentrations should be monitored in patients on concurrent ibuprofen therapy.

Page 6 of 12

Cardiac glycosides

NSAIDs may exacerbate cardiac failure, reduce glomerular filtration rate and increase plasma

cardiac glycoside levels. Care should therefore be taken in patients treated with cardiac glycosides.


The concomitant administration of ibuprofen and cholestyramine may reduce the absorption of

ibuprofen in the gastrointestinal tract. However, the clinical significance is unknown.


Increased risk of gastrointestinal ulceration or bleeding.

Herbal extracts

Ginkgo biloba may potentiate the risk of bleeding with NSAIDs.

Other analgesics

Avoid concomitant use of two or more NSAIDs, including aspirin and cyclooxygenase-2 (COX-2)

selective inhibitors, because of the potential of increased adverse effects. Ibuprofen antagonizes the

irreversible inhibition of platelet COX-1 induced by low dose aspirin. To reduce this effect, ibuprofen

should be administered at least 8 hours before or 30 minutes after taking low dose aspirin.

Experimental data suggest that ibuprofen may competitively inhibit the effect of low dose aspirin on

platelet aggregation when they are dosed concomitantly. Some pharmacodynamic studies show that

when single doses of ibuprofen 400 mg were taken within 8 hours before, or within 30 minutes after

immediate release aspirin (81 mg), a decreased effect of aspirin on the formation of thromboxane or

platelet aggregation occurred. Although there are uncertainties regarding extrapolation of these data

to the clinical situation, the possibility that regular, long-term use of ibuprofen may reduce the

cardioprotective effect of low-dose acetylsalicylic acid cannot be excluded. No clinically relevant

effect is considered to be likely for occasional ibuprofen use (see section 5.1).

Ciclosporin or tacrolimus

Increased risk of nephrotoxicity when used with NSAIDs.


NSAIDs inhibit tubular secretion of methotrexate in animals. As a result, reduction of clearance of

methotrexate may occur. Use of high doses of methotrexate concomitant with NSAIDs should be

avoided. At low doses of methotrexate caution should be used if ibuprofen is administered









antiprostaglandin properties of NSAIDs including acetylsalicylic acid. Limited evidence suggests that

co-administration of NSAIDs on the day of prostaglandin administration does not adversely influence

the effects of mifepristone or the prostaglandin on cervical ripening or uterine contractility and does

not reduce the clinical efficacy of medicinal termination of pregnancy.

Quinolone antibiotics

Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone

antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing



NSAIDs may potentiate the effects of sulfonylurea medications. There have been rare reports of

hypoglycemia in patients on sulfonylurea medications receiving ibuprofen.

Increased risk of hematological toxicity when NSAIDs are given with zidovudine. There is evidence

of an increased risk of hemarthroses and hematoma in HIV(+) hemophiliacs receiving concurrent

treatment with zidovudine and ibuprofen.


Ibuprofen like other NSAIDs can reduce the antihypertensive effect of ACE inhibitors, angiotensin II-

receptor antagonists and beta-blockers with possible loss of blood pressure control and can

attenuate the natriuretic effects of diuretics. Diuretics can also increase the risk of nephrotoxicity of

NSAIDs. The combined use of the three classes of drugs, diuretics, an ACE inhibiting drug (ACE-

inhibitor or angiotensin receptor antagonist) and an anti-inflammatory drug (NSAID or COX-2

inhibitor) all at the same time increases the risk of renal impairment (see section 4.4).

CYP2C9 inhibitors

Concomitant administration of ibuprofen with CYP2C9 inhibitors may increase the exposure to

ibuprofen (CYP2C9 substrate). In a study with voriconazole and fluconazole (CYP2C9 inhibitors),

an increased S(+)-ibuprofen exposure by approximately 80 to 100% has been shown. Reduction of

the ibuprofen dose should be considered when potent CYP2C9 inhibitors are administered

concomitantly, particularly when high-dose ibuprofen is administered with either voriconazole or



Fertility, pregnancy and lactation

Inhibition of prostaglandin synthesis may adversely affect the pregnancy and/or embryo/foetal

development. Data from epidemiological studies suggest an increased risk of miscarriage and of

cardiac malformation and gastroschisis after the use of a prostaglandin synthesis inhibitor in early

pregnancy. The risk is believed to increase with dose and duration of therapy. In animals, the

administration of a prostaglandin synthesis inhibitor has been shown to result in increased pre- and

post-implantation losses and embryo/foetal lethality. In addition, increased incidences of various

malformations, including cardiovascular, have been reported in animals given a prostaglandin

synthesis inhibitor during the organogenetic period.

During the first and second trimester of pregnancy, ibuprofen should not be given unless clearly

necessary. If ibuprofen is used by a woman attempting to conceive, or during the first or second

trimester of pregnancy, the dose should be kept as low and duration of treatment as short as


During the third trimester of pregnancy, all prostaglandin synthesis inhibitors may expose the foetus

to the following:

Cardiopulmonary toxicity (with premature closure of the ductus arteriosus and pulmonary


Renal dysfunction, which may progress to renal failure with oligohydramnios.

At the end of pregnancy, prostaglandin synthesis inhibitors may expose the mother and the neonate

to the following:

Possible prolongation of bleeding time

Inhibition of uterine contractions, which may result in delayed or prolonged labor.

Consequently, ibuprofen is contraindicated during the third trimester of pregnancy.

Use in labour and delivery

Administration of ibuprofen is not recommended during labor and delivery. The onset of labor may

be delayed and the duration increased with a greater bleeding tendency in both mother and child.


Ibuprofen is not recommended for use in nursing mothers.


The use of ibuprofen may impair female fertility and is not recommended in women attempting to

conceive. In women who have difficulties conceiving or who are undergoing investigation of infertility,

withdrawal of ibuprofen should be considered.


Effects on ability to drive and use machines

Following treatment with ibuprofen, the reaction time of patients may be affected. Care should be

taken when driving or operating machinery as the activity may be affected by dizziness, drowsiness,

fatigue and visual disturbance. This applies to a greater extent in combination with alcohol.


Undesirable effects


Hypersensitivity reactions have been reported following treatment with ibuprofen. These may consist

of (a) non-specific allergic reaction and anaphylaxis, (b) respiratory tract reactivity comprising

asthma, aggravated asthma, bronchospasm or dyspnoea, or (c) assorted skin disorders, including

The most commonly observed adverse events are gastrointestinal in nature. Nausea, vomiting,

diarrhoea, flatulence, constipation, dyspepsia, abdominal pain, melaena, haematemesis, ulcerative

stomatitis and gastrointestinal haemorrhage and exacerbation of colitis and Crohn’s disease (see

section 4.3) have been reported following ibuprofen administration.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicine is important. It allows

continued monitoring of the benefit/risk balance of the medicine. Healthcare professionals are asked

to report any suspected adverse reactions




Signs and symptoms of toxicity have generally not been observed at doses below 100 mg/kg in

children or adults. However, supportive care may be needed in some cases. Children have been

observed to manifest signs and symptoms of toxicity after ingestion of 400 mg/kg or greater.


Most patients who have ingested significant amounts of ibuprofen will manifest symptoms within 4

to 6 hours.

The most frequently reported symptoms of overdose include nausea, vomiting, abdominal pain,

lethargy and drowsiness. Central nervous system (CNS) effects include headache, tinnitus,

dizziness, convulsion and loss of consciousness. Nystagmus, metabolic acidosis, hypothermia,

renal effects, gastrointestinal bleeding, coma, apnoea and depression of the CNS and respiratory

system have also been rarely reported. Cardiovascular toxicity, including hypotension, bradycardia

and tachycardia, has been reported. In cases of significant overdose, renal failure and liver damage

are possible. Large overdoses are generally well tolerated when no other drugs are being taken.


There is no specific antidote for ibuprofen overdose. Gastric emptying followed by supportive

measures is recommended if the quantity ingested exceeds 400 mg/kg within the previous hour.

Centre (0800 POISON or 0800 764 766).

5. Pharmacological Properties


Pharmacodynamic properties

Pharmacotherapeutic group: Anti-inflammatory and Antirheumatic Products, Non-Steroids. ATC

code: M01AE01.

Ibuprofen is a colourless crystalline stable solid, with a melting point of 75° to 77°C. It is relatively

insoluble in water but readily soluble in most organic solvents.

Pharmacodynamic effects

Ibuprofen is a propionic acid derivative nonsteroidal anti-inflammatory drug (NSAID) with analgesic,

anti-inflammatory and anti-pyretic effects. The drug's therapeutic effects are thought to result from

its inhibitory effect on the enzyme cyclooxygenase, which results in a marked reduction in

prostaglandin synthesis. These properties provide symptomatic relief of inflammation, pain and


Clinical efficacy and safety

Experimental data suggest that ibuprofen may competitively inhibit the effect of low dose aspirin on

platelet aggregation when they are dosed concomitantly. Some pharmacodynamic studies show

that when single doses of ibuprofen 400 mg were taken within 8 hours before or within 30 minutes

after immediate release aspirin dosing (81 mg), a decreased effect of acetylsalicylic acid on the

formation of thromboxane or platelet aggregation occurred. Although there are uncertainties

regarding extrapolation of these data to the clinical situation, the possibility that regular, long-term

use of ibuprofen may reduce the cardioprotective effect of low-dose acetylsalicylic acid/aspirin

cannot be excluded. No clinically relevant effect is considered to be likely for occasional ibuprofen

use (see section 4.5).


Pharmacokinetic properties

Ibuprofen is a racemic mixture of [+]S- and [-]R-enantiomers.


The sustained release form of ibuprofen is formulated to allow a gradual release of the active

substance from the gel matrix, with a slower release compared to immediate-release formulations

and a lower peak serum concentration which is reached about 3 hours after administration.

Ibuprofen diffuses through an outer gel layer which erodes allowing the aqueous medium to

penetrate further into the core. The sustained absorption phase that results provides prolonged

plasma levels of ibuprofen in the systemic circulation, reducing the dosage frequency normally

required for a drug with a plasma half life of about two hours.

The mean plasma profile of two sustained release 800 mg tablets compared to one conventional

release 400mg tablet taken four times daily, showed that the sustained release formulation reduced

the peaks and troughs characteristic of the conventional release tablets and produced higher mean

plasma levels at 5, 10 and 15 hours and, notably at 24 hours. The area under the plasma
