| Selective COX-2 Inhibitor
With More Safety Profile |
 |
Composition :
| |
Meloxicam is 4-hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1,2-benzothiazine-3-carboxamide-1, 1-dioxide.
|
Action:
MOVIX®
is a nonsteroidal anti-inflammatory drug (NSAID)
of the enolic acid class which has shown anti-inflammatory,
analgesics and antipyretic properties in animals.
MOVIX®
showed anti-inflammatory activity in all standard
models of inflammation. A common mechanism for the
previously mentioned effects may exist in the ability
of MOVIX®
to inhibit the biosynthesis of prostaglandins, known
mediators of inflammation.
Comparison of the ulcerogenic dose and the anti-inflammatory
effective dose in the rat adjuvant arthritis confirmed
the therapeutic margin in animals over standard
NSAIDs.
This improved safety profile is thought to be related
to a selection of COX-2 relative to COX-1. The selective
inhibition of COX-2 relative to COX-1 by MOVIX®
has been demonstrated in vitro on various cell systems:
Guinea pig macrophages, bovine aortic endothelial
cells (for testing for COX-2 activity), and human
recombinant enzymes expressed in cos-cells. Evidence
is now accumulating that COX-2 inhibition provides
the therapeutic effects of NSAIDs whereas inhibition
of constitutive COX-1 is responsible for gastric
and renal side effects. |
Indication :
| Short-term symptomatic
treatment of acute exacerbation of osteoarthritis
and long-term symptomatic treatment of rheumatoid
arthritis (chronic polyarthritis). |
Dosage & Administration:
| Oral
administration: |
Rheumatoid
Arthritis: 15 mg/day. According to the
therapeutic response, the dose may be reduced to
7.5 mg/day.
Osteoarthritis: 7.5 mg/day. If
necessary, the dose may be increased to 15 mg/day.
|
In patients
with increased risk of adverse reactions, start
treatment at the dose of 7.5 mg/day.
As a dosage for use in children has yet to be established,
usage should be restricted to adults.
Tablets should be swallowed with water or other
fluid in conjunction with food. |
Overdosage:
| In case of overdose,
the standard measures of gastric evacuation and
general supportive measures should be used as there
is no known antidote. It has been shown in a clinical
trial that cholestyramine accelerates the elimination
of meloxicam. Severe gastrointestinal lesions may
be treated with antacids and H2-receptor antagonists. |
Contraindications:
Known hypersensitivity
to meloxicam or any excipient of MOVIX®.
There is a potential for cross-sensitivity to acetylsalicylic
acid and other NSAIDs.
MOVIX®
should not be given to patients who have developed
signs of asthma, nasal polyps, angioedema or urticaria
following the administration of acetylsalycilic
acid or other NSAIDs. Active peptic ulceration.
Severe hepatic insufficiency. Nondialysed severe
renal insufficiency. Children and adolescents <15
years. Pregnancy or breastfeeding. Gastrointestinal
bleeding, cerebrovascular bleeding or other bleeding
disorders. |
Precautions:
As with other NSAIDs,
caution should be exercised when treating patients
with a history of upper gastrointestinal disease
and in patients receiving treatment with anticoagulants.
MOVIX®
should be withdrawn if peptic ulceration or gastrointestinal
bleeding occurs.
Special attention should be paid in patients
reporting mucocutaneous adverse events and consideration
given to discontinuing MOVIX®.
NSAIDs inhibit the synthesis of renal prostaglandins
which play a supportive role in the maintenance
of renal perfusion. In patients whose renal blood
flow and blood volume are decreased, administration
of an NSAID may precipitate overt renal decompensation
which is typically followed by recovery to pre-treatment
state upon discontinuation of nonsteroidal anti-inflammatory
therapy. Patients at greatest risk of such a reaction
are dehydrated patients, those with congestive
heart failure, liver cirrhosis, nephrotic syndrome
and overt renal disease, those receiving a diuretic
or those having undergone major surgical procedures
which led to hypovolaemia. In such patients, the
volume of diuresis and the renal function should
be carefully monitored at the beginning of therapy.
In rare instances, NSAIDs may be the cause of
interstitial nephritis, glomerulonephritis, renal
medularry necrosis or nephrotic syndrome.
The dose of MOVIX®
in patients with end-stage renal failure on haemodialysis
should not be higher than 7.5 mg. No dose reduction
is required in patients with mild or moderate
renal impairment (ie, in patients with a creatinine
clearance of>25 mL/min).
As with most other NSAIDs, occasional elevations
of serum transaminases or other parameters of
liver function have been reported. In most cases,
these have been small and transient increases
above the normal range. If the abnormality is
significantor persistent, MOVIX®
should be stopped and follow-up tests carried
out.
Frail or debilitated patients may tolerate side
effects less well and such patients should be
carefully supervised. As with other NSAIDs, caution
should be used in the treatment of elderly patients
who are more likely to be suffering from impaired
renal, hepatic or cardiac function.
MOVIX®
suppositories should not be used in patients with
any inflammatory lesions of the rectum or anus,
or in patients with a recent history of rectal
or anal bleeding.
Effects on the Ability of Drive or Operate Machinery:
There are no specific studies about effects on
the ability to drive vehicles and to use machinery.
However, when adverse effects eg, vertigo and
drowsiness occur, it is advisable to refrain from
these activities.
Use in pregnancy & lactation:
In animals, lethal effects on the embryo have
been reported at doses higher than those used
clinically. (See Contraindications). |
Adverse Reactions:
The following adverse
events which may be causally related with the
administration of MOVIX®
have been reported. The following frequencies
are based on corresponding occurrences in clinical
trials, regardless of any causal relationship.
The information is based on clinical trials
involving 3750 patients who have been treated
with daily oral doses of 7.5 – 15 mg MOVIX®
tablets over a period of up to 18 months (mean
duration of treatment: 127 days).
Gastrointestinal: More frequent
than 1%.: Dyspepsia, nausea, vomiting, abdominal
pain, constipation, flatulence, diarrhea. Between
0.1% & 1%: Disturbances of blood count, including
differential white cell count, leucopenia and
thrombocytopenia. Concomitant administration of
a potentially myelotoxic drug, in particular methotrexate,
appears to be a predisposing factor to the onset
of a cytopenia.
Dermatological: More frequent
than 1%: Pruritus, skin rash. Between 0.1% and
1%: Stomatitis, urticaria. Less frequent than
0.1%: Photosensitisation.
Respiratory: Less frequent
than 0.1%: Onset of acute asthma has been reported
in certain individuals following the administration
of aspirin or other NSAIDs, including MOVIX®.
Central Nervous System: More
frequent than 1%: Lightheadedness, headache. Between
0.1% and 1%: Increase in blood pressure, palpitations,
flushes.
Genitourinary: Between 0.1%
and 1%: Abnormal renal function parameters (increased
serum creatinine and/or serum urea).
Liver Function: Raised transaminases
or bilirubin. |
Interactions:
Other NSAIDs (including
salicylates in high doses): Concomitant administration
of more than one NSAID may increase the risk of
gastrointestinal ulceration and bleeding through
synergistic action.
Oral Anticoagulants, Ticlopidine, Systemically
Administered Heparin, Thrombolytics: Increased
risk of bleeding. If such co-prescribing cannot
be avoided, close monitoring of the effectsof
anticoagulants is required.
Lithium: NSAIDs have been reported
to increase lithium plasma levels. It is recommended
that plasma lithium levels be monitored when initiating,
adjusting and discontinuing MOVIX®.
Methotrexate: As other NSAIDs,
MOVIX®
may increase the haematologic toxicity of methotrexate.
In this situation, strict monitoring of blood
cell count is recommended.
Contraception: NSAIDs have
been reported to decrease the efficacy of intrauterine
devices.
Diuretics: Treatment with NSAIDs
is associated with the potential for acute renal
insufficiency in patients who are dehydrated.
Patients receiving MOVIX®
and diuretics should be adequately hydrated and
be monitored for renal function prior to initiating
treatment.
Antihypertensives (eg, ?-blockers, ACE inhibitors,
vasodilator, diuretics): A reduced effect of the
antihypertensive drug by inhibition of vasodilating
prostaglandins has been reported during treatment
with NSAIDs.
Cholestyramine binds meloxicam in the gastrointestinal
tract leading to a faster elimination of meloxicam.
Nephrotoxicity of cyclosporine may be enhanced
by NSAIDs via renal prostaglandin-mediated effects.
During combined treatment, renal function is to
be measured.
No relevant pharmacokinetic drug-drug interactions
were detected with respect to the concomitant
administration of antacids, cimetidine, digoxin
and furosemide.
Interactions with oral antidiabetics cannot
be excluded. |
