Mesipol

Overdose

Symptoms following acute NSAID overdose are usually limited to lethargy, drowsiness, nausea, vomiting and epigastric pain, which are generally reversible with supportive care. Gastrointestinal bleeding can occur. Severe poisoning may result in hypertension, acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAID and may occur following an overdose.

Patients should be managed with symptomatic and supportive care following an NSAID overdose. Accelerated removal of Mesipol by 4 g oral doses of cholestyramine given three times a day was demonstrated in a clinical trial.

Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard

Preclinical safety data

The toxicological profile of Mesipol has been found in preclinical studies to be identical to that of NSAID: Gastrointestinal ulcers and erosions, renal papillary necrosis at high doses during chronic administration in two animal species.

Oral reproductive studies in the rat have shown a decrease of ovulations and inhibition of implantations and embryotoxic effects (increase of resorptions) at maternotoxic dose levels at 1 mg/kg and higher. Studies of toxicity on reproduction in rats and rabbits did not reveal teratogenicity up to oral doses of 4 mg/kg in rats and 80 mg/kg in rabbits.

The affected dose levels exceeded the clinical dose (7.5-15 mg) by a factor of 10 to 5-fold on a mg/kg dose basis (75 kg person). Foetotoxic effects at the end of gestation, shared by all prostaglandin synthesis inhibitors, have been described.

No evidence has been found of any mutagenic effect, either in vitro or in vivo. No carcinogenic risk has been found in the rat and mouse at doses far higher than those used clinically.

Pharmacodynamic properties

Pharmacotherapeutic group: Non steroidal anti-inflammatory agents, oxicams

ATC code: M01 AC06

Mesipol is a non-steroidal anti-inflammatory drug (NSAID) of the oxicam family, with anti-inflammatory, analgesic and antipyretic properties.

The anti-inflammatory activity of Mesipol has been proven in classical models of inflammation. As with other NSAID, its precise mechanism of action remains unknown. However, there is at least one common mode of action shared by all NSAID (including Mesipol): inhibition of the biosynthesis of prostaglandins, known inflammation mediators.

Pharmacokinetic properties

Absorption

Mesipol is well absorbed from the gastrointestinal tract, which is reflected by a high absolute bioavailability of 89% following oral administration (capsule). Tablets, oral suspension and capsules were shown to be bioequivalent.

Following single dose administration of Mesipol, mean maximum plasma concentrations achieved within 2 hours for the suspension and within 5-6 hours with solid oral dosage forms (capsules and tablets).

With multiple dosing, steady state conditions were reached within 3 to 5 days. Once daily dosing leads to drug plasma concentrations with a relatively small peak-trough fluctuation in the range of 0.4 - 1.0 µg/ml for 7.5 mg doses and 0.8 - 2.0 µg/ml for 15 mg doses, respectively (cmin and cmax at steady state, respectively). Maximum plasma concentrations of Mesipol at steady state, are achieved within five to six hours for the tablet, capsule and the oral suspension, respectively. Extent of absorption for Mesipol following oral administration is not altered by concomitant food intake.

Distribution

Mesipol is very strongly bound to plasma proteins, essentially albumin (99%). Mesipol penetrates into synovial fluid to give concentrations approximately half of those in plasma.

Volume of distribution is low, on average 11 L. Inter-individual variation is the order of 30-40%.

Biotransformation

Mesipol undergoes extensive hepatic biotransformation. Four different metabolites of Mesipol were identified in urine, which are all pharmacodynamically inactive. The major metabolite, 5'-carboxyMesipol (60% of dose), is formed by oxidation of an intermediate metabolite 5'- hydroxymethylMesipol, which is also excreted to a lesser extent (9% of dose). In vitro studies suggest that CYP 2C9 plays an important role in this metabolic pathway, with a minor contribution from the CYP 3A4 isoenzyme. The patient's peroxidase activity is probably responsible for the other two metabolites, which account for 16% and 4% of the administered dose respectively. Elimination

Mesipol is excreted predominantly in the form of metabolites and occurs to equal extents in urine and faeces. Less than 5% of the daily dose is excreted unchanged in faeces, while only traces of the parent compound are excreted in urine.

The mean elimination half-life is about 20 hours. Total plasma clearance amounts on average 8 mL/min. Linearity/non-linearity

Mesipol demonstrates linear pharmacokinetics in the therapeutic dose range of 7.5 mg 15 mg following per oral or intramuscular administration.

Special populations

Hepatic/renal insufficiency:

Neither hepatic, nor mild nor moderate renal insufficiency has a substantial effect on Mesipol pharmacokinetics. In terminal renal failure, the increase in the volume of distribution may result in higher free Mesipol concentrations, and a daily dose of 7.5 mg must not be exceeded.

Elderly:

Mean plasma clearance at steady state in elderly subjects was slightly lower than that reported for younger subjects.

Meloxicam

Special warnings and precautions for use

The recommended maximum daily dose should not be exceeded in case of insufficient therapeutic effect, nor should an additional NSAID be added to the therapy because this may increase the toxicity while therapeutic advantage has not been proven. The use of Mesipol Orodispersible Tablets with concomitant NSAIDs including cyclooxygenase-2 selective inhibitors should be avoided.

Mesipol Orodispersible Tablets is not appropriate for the treatment of patients requiring relief from acute pain.In the absence of improvement after several days, the clinical benefit of the treatment should be reassessed.

Any history of oesophagitis, gastritis and/or peptic ulcer must be sought in order to ensure their total cure before starting treatment with Mesipol. Attention should routinely be paid to the possible onset of a recurrence in patients treated with Mesipol and with a past history of this type.

Gastrointestinal effects

GI bleeding, ulceration or perforation, which can be fatal, has been reported with all NSAIDs at anytime during treatment, with or without warning symptoms or a previous history of serious GI events.

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 , 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 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 is advised in patients receiving concomitant medications which could increase the risk of ulceration or bleeding, such as heparin as curative treatment or given in geriatrics, anticoagulants such as warfarin, or other non steroidal anti-inflammatory drugs, including acetylsalicylic acid given at anti-inflammatory doses (> 1g as single intake or > 3g as total daily amount).

When GI bleeding or ulceration occurs in patients receiving Mesipol orodispersible tablets the treatment should be withdrawn.

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.

Clinical monitoring of blood pressure for patients at risk is recommended at baseline and especially during treatment initiation with Mesipol Orodispersible Tablets.

Clinical trial and epidemiological data suggest that use of some NSAIDs (particularly at high doses and in long term treatment) may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke). There are insufficient data to exclude such a risk for Mesipol.

Patients with uncontrolled hypertension, congestive heart failure, established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated with Mesipol orodispersible tablets after careful consideration. Similar consideration should be made before initiating longer-term treatment of patients with risk factors for cardiovascular disease (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking).

Skin reactions

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 NSAIDSs (see 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. Mesipol should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.

Parameters of liver and renal function

As with most NSAIDs, occasional increases in serum transaminase levels, increases in serum bilirubin or other liver function parameters, as well as increases in serum creatinine and blood urea nitrogen as well as other laboratory disturbances, have been reported. The majority of these instances involved transitory and slight abnormalities. Should any such abnormality prove significant or persistent, the administration of Mesipol should be stopped and appropriate investigations undertaken.

Functional renal failure

NSAIDs, by inhibiting the vasodilating effect of renal prostaglandins, may induce a functional renal failure by reduction of glomerular filtration. This adverse event is dose-dependant. At the beginning of the treatment, or after dose increase, careful monitoring of diuresis and renal function is recommended in patients with the following risk factors:

- Elderly

- Interaction with other medicinal products and other forms of interaction)

- Hypovolemia (whatever the cause)

- Congestive heart failure

- Renal failure

- Nephrotic syndrome

- Lupus nephropathy

- Severe hepatic dysfunction (serum albumin <25 g/l or Child-Pugh score 10)'

In rare instance NSAIDs may be the cause of interstitial nephritis, glomerulonephritis, renal medullary necrosis or nephrotic syndrome.

The dose of Mesipol in patients with end-stage renal failure on haemodialysis should not be higher than 7.5 mg (half a 15 mg tablet). No dose reduction is required in patients with mild or moderate renal impairment (i.e. patients with a creatinine clearance of greater than 25 ml/min).

Sodium, potassium and water retention

Induction of sodium, potassium and water retention and interference with the natriuretic effects of diuretics may occur with NSAIDs. Furthermore, a decrease of the antyhypertensive effect of antyhypertensive drugs can occur. Consequently, oedema, cardiac failure or hypertension may be precipitated or exacerbated in susceptible patients as a result. Clinical monitoring is therefore necessary for patients at risk.

Hyperkalaemia

Hyperkalaemia can be favoured by diabetes or concomitant treatment known to increase kalaemia. Regular monitoring of potassium values should be performed in such cases.

Adverse reactions are often less well tolerated in elderly, fragile or weakened individuals, who therefore require careful monitoring. As with other NSAIDs, particular caution is required in the elderly, in whom renal, hepatic and cardiac functions are frequently impaired. The elderly have an increased frequency of adverse reactions to NSAIDs especially gastrointestinal bleeding and perforation which may be fatal.

Mesipol orodispersible tablet, as any other NSAID may mask symptoms of an underlying infectious disease.

The use of Mesipol orodispersible tablet, as with any drug known to inhibit cyclooxygenase / prostaglandin synthesis, may impair 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 Mesipol should be considered.

Mesipol orodispersible tablet contains a source of phenylalanine:

Aspartame (E951) and may be harmful for people with phenylketonuria.

Mesipol orodispersible tablet contains Sorbitol (E420): Patients with rare hereditary problems of fructose intolerance should not take this medicine.

Effects on ability to drive and use machines

There are no specific studies on the ability to drive and use machinery. However, on the basis of the pharmacodynamic profile and reported adverse drug reactions, Mesipol is likely to have no or negligible influence on these abilities. However, when visual disturbances or drowsiness, vertigo or other central nervous system disturbances occur, it is advisable to refrain from driving and operating machinery.

Dosage (Posology) and method of administration

Oral Use

- Exacerbations of Osteoarthritis: 7.5 mg/day (half a 15 mg tablet); if necessary, in the absence of improvement, the dose may be increased to 15 mg/day.

- Rheumatoid arthritis, Ankylosing Spondylitis: 15 mg/day (one 15 mg tablets).

(See also 'Special Populations')

According to the therapeutic response, the dose may be reduced to 7.5 mg/day (half a 15mg tablet).

Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms. The patient's need for symptomatic relief and response to therapy should be re-evaluated periodically, especially in patients with osteoarthritis.

DO NOT EXCEED THE DOSE OF 15 MG/DAY.

Mesipol Orodispersible Tablets should be placed in the mouth on the tongue and allowed to dissolve slowly for five minutes (the tablet should not be chewed and should not be swallowed undissolved), before swallowing with a drink of 240 ml of water.
