MOBITIL
is a new potent nonsteroidal
anti-inflammatory drug, belonging
to the enolic acid group.
It acts through the preferential
inhibition of cyclo-oxygenase-2
(COX-2), with potentially
high anti-inflammatory and
analgesic actions. Meloxicam-beta-cyclodextrin
is a novel formulation of
meloxicam, which is the product
of supermolecular encapsulation
of meloxicam with the cyclic
oligosaccharide beta-cyclodextrin.
As a result, the absorption
rate of meloxicam is increased
with a more rapid onset of
action and reduced gastropathic
effects.

| PHARMACOLOGY: |
 |
 |
Nonsteroidal
anti-inflammatory drugs (NSAIDs)
are potent anti-inflammatory
agents that act through the
inhibition of the cyclo- oxygenase
(COX) enzyme and the subsequent
inhibition of prostaglandin
synthesis at the site of inflammation.
Recently two isoforms of the
COX enzyme have been identified;
1-
COX-1, which
is constitutively (naturally)
expressed in many cells and
tissues including the gastric
mucosa, where the inhibition
of COX-1 is responsible for
the toxicity associated with
the clinically active NSAIDs.
2-
COX-2, which
is induced by the proinflammatory
cytokines at the site of inflammation,
where the anti-inflammatory
properties of NSAIDs are caused
by the inhibition of inducible
COX-2.
MOBITIL preferentially inhibits
COX-2 enzyme.  |

 |
| PROPERTIES: |
 |
 |
Anti-inflammatory.
Analgesic.
Anti-pyretic.
Inhibitor of both bradykinin-induced
and PAF-induced bronchospasm
without exacerbation of acetylcholine-induced
bronchospasm (i.e. relatively
safe in asthmatic patients).  |

 |
| PHARMACOKINETICS: |
 |
 |
Absorption :
Almost complete after oral
or rectal administration.
The absorption rate of meloxicam
from the inclusion complex
of meloxicam-beta-cyclodextrin
is very rapid and accordingly,
meloxicam is almost immediately
bioavailable after oral or
rectal administration. Pharmacokinetic
characteristics, other than
absorption, remain unchanged.
Distribution :
Plasma
protein binding : 99.1 - 99.7
%.
Steady
state plasma concentration
: Achieved within 3-5 days.
Metabolism : Meloxicam is
extensively metabolized in
the liver, with only traces
of the drug appearing unchanged
in the urine and feces. The
main metabolites are formed
by hydroxylation and further
oxidation of the methyl group
of the thiazolyl moiety.
Excretion :
Meloxicam
is excreted through both renal
and hepatic pathways. The
excretion of a single dose
is complete in 6 days.
Elimination
half life (t ½) : 17-20
hours.
Total
plasma clearance (CL) : 0.42
- 0.48 liter / hour.
The
pharmacokinetic parameters
of meloxicam are linear over
the dose range of 7.5 -30
mg.
Neither
moderate hepatic insufficiency
nor moderate renal dysfunction
has any relevant effects on
the pharmacokinetics of meloxicam.  |
 |
 |
| INDICATIONS: |
 |
 |
Inflammatory
and degenerative articular and extra-articular
rheumatic diseases of muscles, joints,
joint capsules, bursae, tendons, tendon
sheaths and vertebral column such as
chronic rheumatoid arthritis, osteoarthritis,
arthrosis, spondylarthrosis, ankylosing
spondylitis, soft tissue rheumatism,
bursitis, tenditis, lumbago, sciatica
and other types of neuritis and neuralgia.
Post-traumatic
and post-operative pain, inflammation
and swelling.
Painful
syndromes of the vertebral
column.
Painful
and/or inflammatory conditions
in gynecology such as primary
dysmenorrhea or adnexitis.
 |
 |
 |
| CONTRAINDICATIONS
and PRECAUTIONS |
 |
 |
Hypersensitivity
to the oxicam group of NSAIDs.
Use
with caution in patients known
to be hypersensitive to other
NSAIDs or
aspirin as there is a probability
for cross sensitivity.
Active
peptic ulcer.
Severe
hepatic insufficiency.
Severe,
non-dialyzed renal insufficiency.
Pregnancy
and breast-feeding.
 |
 |
 |
| INTERACTIONS |
 |
 |
No
interactions were reported
following the concomitant
administration of food, cimetidine,
antacids, aspirin, digoxin,
warfarin, methotrexate, or
furosemide.
Cholestyramine
binds meloxicam in the gastrointestinal
tract leading to a decreased
absorption of meloxicam.
 |
 |
 |
| ADVERSE
REACTIONS |
 |
 |
The
following adverse reactions
were infrequently reported (not
more than 1%) in the clinical
trials:
CNS
: Headache, drowsiness, tinnitus.
GIT
: Dyspepsia, nausea, flatulence,
diarrhea or constipation.
Cardiovascular
: Peripheral edema.
Dermatological
: Pruritus, skin rash.  |
 |
 |
| DOSAGE
AND ADMINISTRATION |
 |
 |
Orally
: Depending on the severity
of the condition, the recommended
oral dose is 7.5mg to 15mg taken
after meals once daily.
Rectally
: One suppository containing
15mg once daily.
The
maximum recommended daily dose
is 15mg either orally, rectally
or combined.
Dosage
adjustments are not required
in the elderly or in case of
mild to moderate liver or renal
insufficiency.
In
patients with severe renal failure,
the daily dosage should not
exceed 7.5mg.  |
