1. What Preservex is and what it is used for

Preservex belongs to a group of medicines

called non-steroidal anti-inflammatory drugs

(NSAIDs). They have anti-inflammatory and

painkiller properties causing a lowering of

swelling, redness (inflammation) and pain.

The medicine/active ingredient of Preservex

is aceclofenac.

Preservex works by blocking the production

of hormone-like substances called

prostaglandins. Prostaglandins have many

functions in the body including an

important role in both the way the body

responds to inflammation and also the

reabsorption of calcium in some diseases of

the bone

Preservex is used to relieve pain and reduce

redness and swelling (inflammation) in

patients suffering from:

Osteoarthritis - inflammation of the joints.

This is a common condition in patients

over the age of 50 and causes damage to

the tissues and bones in the joints.

Rheumatoid arthritis - long term

inflammation of the joints caused by the

body’s own immune system (autoimmune


Ankylosing spondylitis - inflammation of

the spine/backbone which can lead to the

joints fusing together.

PRESERVEX® 100 mg film-coated tablets



Each tablet contains 100 mg of aceclofenac.



Preservex film-coated tablets 100 mg are presented as white round film-coated

tablets, 8 mm in diameter.


Therapeutic indications

Preservex is indicated for the relief of pain and inflammation in osteoarthritis,

rheumatoid arthritis and ankylosing spondylitis.


Posology and method of administration

Preservex film-coated tablets are supplied for oral administration.


When Preservex was administered to fasting and fed healthy volunteers only the rate and not

the extent of aceclofenac absorption was affected.

Undesirable effects may be minimised by using the lowest effective dose for the shortest

duration necessary to control symptoms (see section 4.4

Special warnings and precautions for



The recommended dose is 200 mg daily, taken as two separate 100 mg doses, one tablet in the

morning and one in the evening.

Paediatric population

There are no clinical data on the use of Preservex in children and therefore it is not

recommended for use in children.


The elderly, who are more likely to be suffering from impaired renal, cardiovascular or

hepatic function and receiving concomitant medication, are at increased risk of the serious

consequences of adverse reactions. If an NSAID is considered necessary, the lowest effective

dose should be used and for the shortest possible duration. The patient should be monitored

regularly for GI bleeding during NSAID therapy.

The pharmacokinetics of Preservex are not altered in elderly patients, therefore it is not

considered necessary to modify the dose or dose frequency.

Renal insufficiency

There is no evidence that the dosage of Preservex needs to be modified in patients with mild

renal impairment, but as with other NSAIDs caution should be exercised (see also


Hepatic insufficiency

There is some evidence that the dose of Preservex should be reduced in patients with hepatic

impairment and it is suggested that an initial daily dose of 100 mg be used.

Method of administration

To be taken preferably with or after food. The tablets should be swallowed whole with a

sufficient quantity of liquid.



Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Active, or history of recurrent peptic ulcer/haemorrhage (two or more distinct episodes of

proven ulceration or bleeding).

NSAIDs are contraindicated in patients who have previously shown hypersensitivity reactions

(e.g. asthma, rhinitis, angioedema or urticaria) in response to ibuprofen, aspirin, or other non-

steroidal anti-inflammatory drugs.

Hepatic failure and renal failure (see section 4.4).

Patients with established congestive heart failure (NYHA II-IV), ischemic heart disease,

peripheral arterial disease and/or cerebrovascular disease.

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

Active bleedings or bleeding disorders.

Preservex should not be prescribed during pregnancy, especially during the last trimester of

pregnancy, unless there are compelling reasons for doing so. The lowest effective dosage

should be used (see section 4.6).


Special warnings and precautions for use

Undesirable effects may be minimised by using the lowest effective dose for the

shortest duration necessary to control symptoms (see section 4.2, and GI and

cardiovascular risks below).

The use of Preservex with concomitant NSAIDs including cyclooxygenase-2 selective

inhibitors should be avoided (see section 4.5).


The elderly have an increased frequency of adverse reactions to NSAIDs especially

gastrointestinal bleeding and perforation which may be fatal (see section 4.2).

Respiratory disorders:

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

history of, bronchial asthma since NSAIDs have been reported to precipitate

bronchospasm in such patients.

Cardiovascular, Renal and Hepatic Impairment:

The administration of an NSAID may cause a dose dependent reduction in

prostaglandin formation and precipitate renal failure. Patients at greatest risk of this

reaction are those with impaired renal function, cardiac impairment, liver dysfunction,

those taking diuretics or recovering from major surgery, and the elderly. The

importance of prostaglandins in maintaining renal blood flow should be taken into

account in these patients.

Renal function should be monitored in these patients (see also section 4.3).


Patients with mild to moderate renal impairment should be kept under surveillance,

since the use of NSAIDs may result in deterioration of renal function. The lowest

effective dose should be used and renal function monitored regularly. Effects on renal

function are usually reversible on withdrawal of Preservex.


If abnormal liver function tests persist or worsen, clinical signs or symptoms

consistent with liver disease develop or if other manifestations occur (eosinophilia,

rash), Preservex should be discontinued. Close medical surveillance is necessary in

patients suffering from mild to moderate impairment of hepatic function. Hepatitis

may occur without prodromal symptoms.

Use of Preservex in patients with hepatic porphyria may trigger an attack.

Cardiovascular and cerebrovascular effects:

Appropriate monitoring and advice are required for patients with a history of hypertension

and/or mild to moderate congestive heart failure as fluid retention and oedema have been

reported in association with NSAID therapy.

Patients with congestive heart failure ( NYHA-I) and patients with significant risk

factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes

mellitus, smoking) should only be treated with aceclofenac after careful consideration.

As the cardiovascular risks of aceclofenac may increase with dose and duration of

exposure, the shortest duration possible and the lowest effective daily dose should be

used. The patient's need for symptomatic relief and response to therapy should be re-

evaluated periodically.

Aceclofenac should also be administered with caution and under close medical

surveillance to patients with a history of cerebrovascular bleeding.

Gastrointestinal bleeding, ulceration and perforation:

GI bleeding, ulceration or perforation, which can be fatal, has been reported with all

NSAIDs at any time during treatment, with or without warning symptoms or a

previous history of serious GI events.

Close medical surveillance is imperative in patients with symptoms indicative of

gastro-intestinal disorders involving either the upper or lower gastrointestinal tract,

with a history suggestive of gastro-intestinal ulceration, bleeding or perforation, with

ulcerative colitis or with Crohn's disease, or haematological abnormalities, as these

conditions may be exacerbated (see section 4.8)

The risk of GI bleeding, ulceration or perforation is higher with increasing NSAID

doses, in patients with a history of ulcer, particularly if complicated with haemorrhage

or perforation (see section 4.3), and in the elderly. These patients should commence

treatment on the lowest dose available. Combination therapy with protective agents

(e.g. misoprostol or proton pump inhibitors) should be considered for these patients,

and also

for patients requiring concomitant low dose aspirin, or other drugs

likely to increase gastrointestinal risk (see below and section 4.5).

Patients with a history of GI toxicity, particularly when elderly, should report any unusual

abdominal symptoms (especially GI bleeding) particularly in the initial stages of treatment.

Caution should be advised in patients receiving concomitant medications which could

increase the risk of ulceration or bleeding, such as systemic corticosteroids, anticoagulants

such as warfarin, selective serotonin-reuptake inhibitors or antiplatelet agents such as

aspirin (see section 4.5).

When GI bleeding or ulceration occurs in patients receiving aceclofenac, the treatment

should be withdrawn.

SLE and mixed connective tissue disease:

In patients with systemic lupus erythematosus (SLE) and mixed connective tissue

disorders there may be an increased risk of aseptic meningitis (see section 4.8).


Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-

Johnson syndrome, and toxic epidermal necrolysis, have been reported very rarely in

association with the use of NSAIDs (see section 4.8). Patients appear to be at highest risk

for these reactions early in the course of therapy: the onset of the reaction occurring in the

majority of cases within the first month of treatment. Preservex should be discontinued at

the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.

Exceptionally, varicella can trigger serious cutaneous and soft tissues infections

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 aceclofenac in case of


Hypersensitivity reactions:

As with other NSAIDs, allergic reactions, including anaphylactic/anaphylactoid reactions,

can also occur without earlier exposure to the drug.


Preservex may reversibly inhibit platelet aggregation (see section 4.5 anticoagulants under


Long-term treatment:

All patients who are receiving NSAIDs should be monitored as a precautionary measure

e.g. renal, hepatic function (elevation of liver enzymes may occur) and blood counts.


Interaction with other medicaments and other forms of interaction

Other analgesics including cyclooxygenase-2 selective inhibitors: Avoid concomitant use of

two or more NSAIDs (including aspirin) as this may increase the risk of adverse effects,

including GI bleeding (see section 4.4).

Anti-hypertensives: NSAID’s may reduce the effect of antihypertensives. The risk of acute

renal insufficiency, which is usually reversible, may be increased in some patients with

compromised renal function (e.g. dehydrated patients or elderly patients) when ACE-

inhibitors or angiotensin II receptor antagonists are combined with NSAIDs. Therefore, the

combination should be administered with caution, especially in the elderly. Patients should be

adequately hydrated and consideration should be given to monitoring of renal function after

initiation of concomitant therapy, and periodically thereafter.

Diuretics: Aceclofenac, like other NSAIDs, may inhibit the activity of diuretics. Diuretics can

increase the risk of nephrotoxicity of NSAIDs. Although it was not shown to affect blood

pressure control when co-administered with bendrofluazide, interactions with other diuretics

cannot be ruled out. When concomitant administration with potassium-sparing diuretics is

employed, serum potassium should be monitored.

Cardiac glycosides, like digoxin: NSAIDs may exacerbate cardiac failure, reduce GFR

(glomerular filtration rate) and inhibit the renal clearance of glycosides, resulting in increased

plasma glycoside levels. The combination should be avoided unless frequent monitoring of

glycoside levels can be performed.

Lithium: Several NSAID drugs inhibit the renal clearance of lithium, resulting in increased

serum concentrations of lithium. The combination should be avoided unless frequent

monitoring of lithium can be performed.

Methotrexate: The possible interaction between NSAIDs and methotrexate should be born in

mind also when low doses of methotrexate are used, especially in patients with decreased

renal function. When combination therapy has to be used, the renal function should be

monitored. Caution should be exercised if both an NSAID and methotrexate are administered

within 24 hours of each other, since NSAIDs may increase plasma levels of methotrexate,

resulting in increased toxicity.

Mifepristone: NSAIDs should not be used for 8-12 days after mifepristone administration as

NSAIDs can reduce the effect of mifepristone.

Corticosteroids: Increased risk of gastrointestinal ulceration or bleeding (see section 4.4).

Anti-coagulants: NSAIDs may enhance the effects of anti-coagulants, such as warfarin (see

section 4.4). Close monitoring of patients on combined anti-coagulants and Preservex therapy

should be undertaken.

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 convulsions.

Anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs): Increased risk of

gastrointestinal bleeding (see section 4.4).

Ciclosporin, tacrolimus: Administration of NSAID drugs together with cyclosporin or

tacrolimus is thought to increase the risk of nephrotoxicity due to decreased synthesis of

prostacyclin in the kidney. During combination therapy it is therefore important to carefully

monitor renal function.

Zidovudine: Increased risk of haematological toxicity when NSAIDs are given with

zidovudine. There are indications of an increased risk of haemarthroses and haematoma in

HIV(+) haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen.

Antidiabetic agents: Clinical studies have shown that diclofenac can be given together with

oral antidiabetic agents with influencing their clinical effect. However, there have been

isolated reports of hypoglycaemic and hyperglycaemic effects. Thus with Preservex,

consideration should be given to adjustment of the dosage of hypoglycaemic agents.


Fertility, pregnancy and lactation


There is no information on the use of aceclofenac during pregnancy. Inhibition of

prostaglandin synthesis may adversely affect the pregnancy and/or the embryo/fetal

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

cardiac malformation or gastroschisis after use of prostaglandin synthesis inhibitor in early

pregnancy. The absolute risk for cardiovascular malformation was increased from less than

1%, up to approximately 1.5 %. The risk is believed to increase with dose and duration of


In animals, administration of a prostaglandin synthesis inhibitor has been shown to result in

increased pre- and post-implantation loss 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, aceclofenac should not be given unless clearly necessary. If

aceclofenac is used by a woman attempting to conceive, or during the first and 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:

cardiopulmonary toxicity (with premature closure of the ductus arteriosus and

pulmonary hypertension);

renal dysfunction, which may progress to renal failure with oligo-hydroamniosis;

the mother and the neonate, at the end of pregnancy, to:

possible prolongation of bleeding time, an anti-aggregating effect which may occur

even at very low doses.

inhibition of uterine contractions resulting in delayed or prolonged labour.

Consequently, aceclofenac is contraindicated during the third trimester of pregnancy (see

section 4.3).


There is no information on the secretion of aceclofenac to breast milk; there was however no

notable transfer of radio labelled (14C) aceclofenac to the milk of lactating rats.

The use of Preservex should therefore be avoided in pregnancy and lactation unless the

potential benefits to the other outweigh the possible risks to the foetus.


The use of Preservex 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 Preservex should be considered.


Effects on ability to drive and use machines

Undesirable effects such as dizziness, drowsiness, vertigo, fatigue, visual disturbances

or other central nervous system disorders are possible after taking NSAIDs. If

affected, patients should not drive or operate machinery.


Undesirable effects

Gastrointestinal: The most commonly-observed adverse events are gastrointestinal in nature.

Peptic ulcers, perforation or GI bleeding, sometimes fatal, particularly in the elderly, may

occur (see section 4.4). Nausea, vomiting, diarrhoea, flatulence, constipation, dyspepsia,

abdominal pain, melaena, haematemesis, ulcerative stomatitis, exacerbation of colitis and

Crohn’s disease (See section 4.4) have been reported following administration. Less

frequently, gastritis has been observed. Pancreatitis has been reported very rarely.

Hypersensitivity: Hypersensitivity reactions have been reported following treatment with

NSAIDs. These may consist of (a) non-specific allergic reactions and anaphylaxis (b)

respiratory tract reactivity comprising asthma, aggravated asthma, bronchospasm or

dyspnoea, or (c) assorted skin disorders, including rashes of various types, pruritus, urticaria,

purpura, angiodema and, more rarely exfoliative and bullous dermatoses (including epidermal

necrolysis and erythema multiforme).

Cardiovascular and cerebrovascular: Oedema, hypertension and cardiac failure have been

reported in association with NSAID treatment

Aceclofenac is both structurally related and metabolised to diclofenac for which a greater

amount of clinical and epidemiological data consistently point towards an increased risk of

general arterial thrombotic events (for example myocardial infarction or stroke, particularly at

high doses or in long treatment). Epidemiological data has also found an increased risk of

acute coronary syndrome and myocardial infarction associated with the use of aceclofenac

(see section 4.3 and 4.4 for Contraindications and Special warnings and special precautions

for use).

Exceptionally, occurrence of serious cutaneous and soft tissues infections complications

during varicella has been reported in association with NSAID treatment

Other adverse reactions reported less commonly include:

Renal: interstitial nephritis.

Neurological and special senses: optic neuritis, reports of aseptic meningitis (especially in

patients with existing auto immune disorders, such as systemic lupus erythematosus, mixed

connective tissue disease), with symptoms such as stiff neck, headache, nausea, vomiting,

fever or disorientation (See section 4.4), confusion, hallucinations, malaise and drowsiness.

Haematological: agranulocytosis, aplastic anaemia .

Dermatological: Bullous reactions including Stevens Johnson Syndrome and Toxic

Epidermal Necrolysis (very rare). Photosensitivity.

If serious adverse reactions occur, Preservex should be withdrawn.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is

important. It allows continued monitoring of the benefit/risk balance of the medicinal product.

Healthcare professionals are asked to report any suspected adverse reactions via the Yellow

Card Scheme, Website: or search for MHRA Yellow Card in

the Google Play or Apple App Store.



a) Symptoms

Symptoms include headache, nausea, vomiting, epigastric pain, gastrointestinal

irritation, gastrointestinal bleeding, rarely diarrhoea, disorientation, excitation, coma,

drowsiness, dizziness, tinnitus, hypotension, respiratory depression, fainting,

occasionally convulsions. In cases of significant poisoning acute renal failure and

liver damage are possible.

b) Therapeutic measure

Patients should be treated symptomatically as required.

Within one hour of ingestion of a potentially toxic amount, activated charcoal should

be considered. Alternatively, in adults, gastric lavage should be considered within one

hour of ingestion of a potentially life-threatening overdose.

Specific therapies such as dialysis or haemoperfusion are probable of no help in

eliminating NSAIDs due to their high rate of protein binding and extensive


Good urine output should be ensured.

Renal and liver function should be closely monitored.

Patients should be observed for at least four hours after ingestion of potentially toxic


In case of frequent or prolonged convulsions, patients should be treated with

intravenous diazepam.

Other measures may be indicated by the patient's clinical condition.

Management of acute poisoning with oral aceclofenac essentially consists of supportive

and symptomatic measures for complications such as hypotension, renal failure,

convulsions, gastro-intestinal irritation, and respiratory depression.


Pharmacodynamic properties

Aceclofenac is a non-steroidal agent with marked anti-inflammatory and analgesic


The mode of action of aceclofenac is largely based on the inhibition to prostaglandin

synthesis. Aceclofenac is a potent inhibitor of the enzyme cyclo-oxygenase, which is

involved in the production of prostaglandins.


Pharmacokinetic properties

After oral administration, aceclofenac is rapidly and completely absorbed as unchanged

drug. Peak plasma concentrations are reached approximately 1.25 to 3.00 hours

following ingestion. Aceclofenac penetrates into the synovial fluid, where the

concentrations reach approximately 57% of those in plasma. The volume of distribution

is approximately 25 L.

The mean plasma elimination half-life is around 4 hours. Aceclofenac is highly protein-

bound (>99%). Aceclofenac circulates mainly as unchanged drug. 4'-

Hydroxyaceclofenac is the main metabolite detected in plasma. Approximately two-

thirds of the administered dose is excreted via the urine, mainly as hydroxymetabolites.

No changes in the pharmacokinetics of aceclofenac have been detected in the elderly.


Preclinical safety data

The results from preclinical studies conducted with aceclofenac are consistent with those

expected for NSAIDs. The principal target organ was the gastro-intestinal tract. No

unexpected findings were recorded.

Aceclofenac was not considered to have any mutagenic activity in three in vitro studies

and an in vivo study in the mouse.

Aceclofenac was not found to be carcinogenic in either the mouse or rat.
