For Painful Musculoskeletal Conditions
Each caplet (capsule shaped tablet) contains:
|Lebec-MR (Chlorzoxazone) ||500 mg|
Inactive ingredients: FD&C Blue No. 1, microcrystalline cellulose, docusate sodium, lactose (hydrous), magnesium stearate, sodium benzoate, sodium starch glycolate, pregelatinized corn starch, D&C Yellow No. 10.
Lebec-MR (Chlorzoxazone) is a centrally-acting agent for painful musculoskeletal conditions. Data available from animal experiments as well as human study indicate that Lebec-MR (Chlorzoxazone) acts primarily at the level of the spinal cord and subcortical areas of the brain where it inhibits multisynaptic reflex arcs involved in producing and maintaining skeletal muscle spasm of varied etiology. The clinical result is a reduction of the skeletal muscle spasm with relief of pain and increased mobility of the involved muscles. Blood levels of Lebec-MR (Chlorzoxazone) can be detected in people during the first 30 minutes and peak levels may be reached, in the majority of the subjects, in about 1 to 2 hours after oral administration of Lebec-MR (Chlorzoxazone). Lebec-MR (Chlorzoxazone) is rapidly metabolized and is excreted in the urine, primarily in a conjugated form as the glucuronide. Less than one percent of a dose of Lebec-MR (Chlorzoxazone) is excreted unchanged in the urine in 24 hours.
Lebec-MR (Chlorzoxazone) Lebec-MR (Chlorzoxazone) is indicated as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions. The mode of action of this drug has not been clearly identified, but may be related to its sedative properties. Lebec-MR (Chlorzoxazone) does not directly relax tense skeletal muscles in man.
Lebec-MR (Chlorzoxazone) Lebec-MR (Chlorzoxazone) is contraindicated in patients with known intolerance to the drug.
Serious hepatocellular toxicity has been reported rarely in patients receiving Lebec-MR (Chlorzoxazone). The mechanism is unknown but appears to be idiosyncratic and unpredictable. Factors predisposing patients to this rare event are not known. Patients should be instructed to report early signs and/or symptoms of hepatotoxicity such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, or jaundice. Lebec-MR (Chlorzoxazone) should be discontinued immediately and a physician consulted if any of these signs or symptoms develop. Lebec-MR (Chlorzoxazone) use should also be discontinued if a patient develops abnormal liver enzymes (e.g. AST, ALT, alkaline phosphatase and bilirubin).
The concomitant use of alcohol or other central nervous system depressants may have an additive effect.
The safe use of Lebec-MR (Chlorzoxazone) Lebec-MR (Chlorzoxazone) has not been established with respect to the possible adverse effects upon fetal development. Therefore, it should be used in women of childbearing potential only when, in the judgment of the physician, the potential benefits outweigh the possible risks.
Lebec-MR (Chlorzoxazone) Lebec-MR (Chlorzoxazone) should be used with caution in patients with known allergies or with a history of allergic reactions to drugs. If a sensitivity reaction occurs such as urticaria, redness, or itching of the skin, the drug should be stopped.
If any symptoms suggestive of liver dysfunction are observed, the drug should be discontinued.
Lebec-MR (Chlorzoxazone) containing products are usually well tolerated. It is possible in rare instances that Lebec-MR (Chlorzoxazone) may have been associated with gastrointestinal bleeding. Drowsiness, dizziness, lightheadedness, malaise, or overstimulation may be noted by an occasional patient. Rarely, allergic-type skin rashes, petechiae, or ecchymoses may develop during treatment. Angioneurotic edema or anaphylactic reactions are extremely rare. There is no evidence that the drug will cause renal damage. Rarely, a patient may note discoloration of the urine resulting from a phenolic metabolite of Lebec-MR (Chlorzoxazone). This finding is of no known clinical significance.
One caplet three or four times daily. If adequate response is not obtained with this dose, it may be increased to 1 ½ caplets (750 mg) three or four times daily. As improvement occurs dosage can usually be reduced.
Initially, gastrointestinal disturbances such as nausea, vomiting, or diarrhea together with drowsiness, dizziness, lightheadedness or headache may occur. Early in the course there may be malaise or sluggishness followed by marked loss of muscle tone, making voluntary movement impossible. The deep tendon reflexes may be decreased or absent. The sensorium remains intact, and there is no peripheral loss of sensation. Respiratory depression may occur with rapid, irregular respiration and intercostal and substernal retraction. The blood pressure is lowered, but shock has not been observed.
Gastric lavage or induction of emesis should be carried out, followed by administration of activated charcoal. Thereafter, treatment is entirely supportive. If respirations are depressed, oxygen and artificial respiration should be employed and a patent airway assured by use of an oropharyngeal airway or endotracheal tube. Hypotension may be counteracted by use of dextran, plasma, concentrated albumin or a vasopressor agent such as norepinephrine. Cholinergic drugs or analeptic drugs are of no value and should not be used.

Revised: March 2012
NSAIDs, a derivative of phenylacetic acid, Lebec-MR has a pronounced anti-inflammatory, analgesic and mild antipyretic effect. The mechanism of action is associated with inhibition of COX activity - the main enzyme metabolism of arachidonic acid, which is a precursor of prostaglandins, which play a major role in the pathogenesis of inflammation, pain and fever. Analgesic effect is due to two mechanisms: peripheral (indirectly, through suppression of prostaglandin synthesis) and central (due to inhibition of prostaglandin synthesis in the central and peripheral nervous system).
Inhibits synthesis of proteoglycan in cartilage.
In rheumatic diseases, Lebec-MR (Diclofenac) reduces joint pain at rest and in motion, as well as morning stiffness and swelling of the joints, helps to increase range of motion; reduces post-traumatic and postoperative pain, and inflammatory edema.
Inhibits platelet aggregation. With prolonged use has a desensitizing effect.
When used topically in ophthalmology reduces swelling and pain in inflammatory processes non-infectious etiology.
After intake is absorbed from the gastrointestinal tract. Eating slows down the rate of absorption, extent of absorption is not changed. About 50% of the active substance is metabolized in the "first passage" through the liver. When used rectally absorption is slower. Time to reach Cmax in plasma after oral administration is 2-4 hours depending on the used dosage form, after rectal - 1 h, I.M. administration - 20 min. The concentration of active substance in plasma is a linear function of the applied dose.
Not cumulative. Plasma protein binding is 99.7% (predominantly albumin). Penetrates into synovial fluid, Cmax is achieved in 2-4 hours later than in plasma.
To a large extent metabolized to form several metabolites, among which two pharmacologically active, but to a lesser extent than Lebec-MR (Diclofenac).
Systemic clearance of the active substance is about 263 ml / min. T1/2 from plasma is 1-2 h, from synovial fluid - 3-6 h. Approximately 60% of the dose was excreted as metabolites by the kidneys, less than 1% excreted in the urine as unchanged, while the rest is displayed in the form of metabolites with bile.
Articular syndrome (rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout), degenerative and chronic inflammatory diseases of musculoskeletal system (osteochondrosis, osteoarthritis, periartropatii), post-traumatic inflammation of soft tissue and musculoskeletal system (sprains, bruises). Pain in the spine, neuralgia, myalgia, arthralgia, pain and inflammation after surgery or injury, pain in gout, migraine, algomenorrhea, pain with Bursitis, proctitis, colic (biliary and renal), pain in infectious and inflammatory diseases of ENT organs.
For local use: the inhibition of miosis during surgery for cataract prevention of cystoid macular edema associated with removal and lens implantation, inflammatory eye non-infectious nature, post-traumatic inflammation in penetrating and nonpenetrating wound of the eyeball.
For oral use for adult single dose is 25-50 mg 2-3 times / 24 h. Frequency of admission depends on the dosage form employed, the severity of the disease and is 1-3 times / 24 h, rectally - 1 times / 24 h, for the treatment of acute conditions or the exacerbation of chronic edema use intramuscular in dose of 75 mg.
For children older than 6 years and adolescents daily dose is 2 mg / kg.
Topical applied at a dose of 2-4 g on the affected area 3-4 times / 24 h.
When used in ophthalmology frequency and duration of administration are determined individually.
The maximum oral daily dose for adults is 150 mg.
Digestive system: nausea, vomiting, anorexia, abdominal pain and discomfort in the epigastrium, flatulence, constipation, diarrhea, and in some cases - erosive-ulcerative lesions, gastrointestinal bleeding and perforation; rarely - abnormal liver function. When rectal administration - in isolated cases were observed inflammation of the colon bleeding, exacerbation of ulcerative colitis.
From the side of the central nervous system and peripheral nervous system: dizziness, headache, agitation, insomnia, irritability, fatigue, rarely - paresthesia, visual disturbances (blurred, double vision), tinnitus, insomnia, cramps, irritability, tremors, mental disorders, depression.
Hemopoietic system: rarely - anemia, leukopenia, thrombocytopenia, agranulocytosis.
Urinary system: rarely - renal failure; in predisposed patients may be swelling.
Dermatological reactions: rarely - hair loss.
Allergic reactions: skin rash, itching, when used in the form of eye drops - itching, redness, photosensitivity.
Local reactions: in the place of I.M. introducing possible burning, in some cases - the formation of infiltration, abscess, necrosis of adipose tissue in the rectal administration may be local irritation, the appearance of mucous discharge mixed with blood, painful defecation, when used externally, in rare cases - itching, redness, rash, burning sensation, when applied topically in ophthalmology may be a transient burning sensation and / or temporary blurred vision immediately after instillation.
With long-term topical use and / or drawing on a vast surface of body are possible systemic side effects due to resorptive action of Lebec-MR (Diclofenac).
known hypersensitivity to Lebec-MR sodium or to any accessory ingredient that is part of the drug Lebec-MR (Diclofenac);
anamnestic information about the attacks of bronchial asthma, urticaria, acute rhinitis associated with the use of aspirin or other NSAIDs;
hemodyscrasia unknown origin;
children under 6 years
pregnancy (III trimester);
increased sensitivity to sulfite (for injection solution).
children under age 15 - tablets of 50 mg to 18 years - injection.
Use during pregnancy and lactation is possible in cases where the potential benefits for the mother exceeds than the potential risk to the fetus or newborn.
With extreme caution is used in diseases of liver, kidney, gastrointestinal history, dyspepsia, asthma, hypertension, heart failure, after major surgery, as well as elderly patients.
When referring to a history of allergic reactions to NSAIDs Lebec-MR and sulfites are used only in urgent cases. In the course of treatment requires systematic monitoring of liver function and kidney picture of peripheral blood.
Do not recommended the use for rectal patients with diseases of anorectal region or anorectal bleeding in history. Topical should be applied only to intact skin areas.
Avoid contact with Lebec-MR (Diclofenac) in the eye (except for eye drops), or on mucous membranes. Patients who use contact lenses, eye drops should be applied no earlier than 5 minutes after removing the lenses.
Not recommended for children under 6 years.
During the period of treatment drugs for systemic use is not recommended alcohol consumption.
During the period of treatment may decrease the speed of psychomotor reactions. With worsening blurred vision after application of eye drops should not be driving and doing other potentially danger activities.
At simultaneous application with Lebec-MR (Diclofenac) antihypertensive drugs may be weakening their actions.
There are few reports on the occurrence of seizures in patients taking both NSAIDs and antibacterial drugs quinolic series.
At simultaneous application with GCS and increased risk of side effects from the digestive system.
With simultaneous use of diuretics may decrease diuretic effect. With the simultaneous use of potassium-sparing diuretics may increase the concentration of potassium in the blood.
With simultaneous use with other NSAIDs may increase the risk of side effects.
There are reports of hypoglycemia or hyperglycemia in patients with diabetes who engaged in Lebec-MR (Diclofenac) together with hypoglycemic drugs.
When applied simultaneously with acetylsalicylic acid may decrease the concentration of Lebec-MR (Diclofenac) in plasma.
Although clinical studies have not found the influence of Lebec-MR (Diclofenac) on the action of anticoagulants, describes the individual cases of bleeding when used with Lebec-MR (Diclofenac) and warfarin.
With simultaneous use may increase digoxin, lithium, and phenytoin in blood plasma.
The absorption of Lebec-MR (Diclofenac) from the gastrointestinal tract is reduced by simultaneous application with kolestiraminom, to a lesser extent - with colestipol.
With simultaneous use may increase the concentration of methotrexate in plasma and increased its toxicity.
With simultaneous application of Lebec-MR (Diclofenac) could not affect the bioavailability of morphine, but the concentration of the active metabolite of morphine may be enhanced in the presence of Lebec-MR (Diclofenac), which increases the risk of side effects metabolites of morphine, including respiratory depression.
When applied simultaneously with pentazocine described a case of great convulsions, and rifampicin - may decrease the concentration of Lebec-MR (Diclofenac) in plasma, with ceftriaxone - increases excretion of ceftriaxone in bile; with cyclosporine - may increase cyclosporine nephrotoxicity.
Symptoms: may cause hypotension, renal failure, convulsions, gastrointestinal irritation or respiratory depression. Treatment: There is no specific antidote. In acute poisoning as soon as possible to stop drug absorption from the gastrointestinal tract. There is indicated gastric lavage, activated charcoal appointment and conduct of other symptomatic and supportive therapy. The use of forced diuresis, dialysis or blood transfusion is not justified because NSAIDs largely associated with serum proteins and possess extensive metabolism.
In a dry, protected from light place, at temperature not above 25°C.Common expiration date for Lebec-MR (Diclofenac) tablets: 3 years.
Depending on the reaction of the Lebec-MR after taken, if you are feeling dizziness, drowsiness or any weakness as a reaction on your body, Then consider Lebec-MR not safe to drive or operate heavy machine after consumption. Meaning that, do not drive or operate heavy duty machines after taking the capsule if the capsule has a strange reaction on your body like dizziness, drowsiness. As prescribed by a pharmacist, it is dangerous to take alcohol while taking medicines as it exposed patients to drowsiness and health risk. Please take note of such effect most especially when taking Primosa capsule. It's advisable to consult your doctor on time for a proper recommendation and medical consultations.Is Lebec-MR addictive or habit forming?
