Flurbinom P

Uses

Carefully consider the potential benefits and risks of Flurbiprofen and other treatment options before deciding to use Flurbiprofen . Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

Flurbiprofen is used for:

• For relief of the signs and symptoms of rheumatoid arthritis.
• For relief of the signs and symptoms of osteoarthritis.

Flurbinom P is also used to associated treatment for these conditions: Ankylosing Spondylitis (AS), Back Pain, Acute, Chronic Back Pain, Menstrual Distress (Dysmenorrhea), Muscle Spasms, Non-Articular Rheumatic Muscle Spasms, Osteoarthritis (OA), Pain, Pain, Inflammatory, Post-traumatic pain, Postoperative pain, Rheumatoid Arthritis, Spinal pain

How Flurbinom P works

Similar to other NSAIAs, the anti-inflammatory effect of flurbiprofen occurs via reversible inhibition of cyclooxygenase (COX), the enzyme responsible for the conversion of arachidonic acid to prostaglandin G2 (PGG2) and PGG2 to prostaglandin H2 (PGH2) in the prostaglandin synthesis pathway. This effectively decreases the concentration of prostaglandins involved in inflammation, pain, swelling and fever. Flurbiprofen is a non-selective COX inhibitor and inhibits the activity of both COX-1 and -2. It is also one of the most potent NSAIAs in terms of prostaglandin inhibitory activity.

Dosage

Flurbinom P dosage

After observing the response to initial therapy with Flurbiprofen , the dose and frequency should be adjusted to suit an individual patient's needs. For relief of the signs and symptoms of rheumatoid arthritis or osteoarthritis, the recommended starting dose of Flurbiprofen is 200 to 300 mg per day, divided for administration two, three, or four times a day. The largest recommended single dose in a multiple-dose daily regimen is 100 mg.

Side Effects

Oedema, abdominal pain, constipation, diarrhoea, dyspepsia/heartburn, liver enzyme elevations, flatulence, nausea, vomiting, wt change, headache, nervousness, CNS stimulation (e.g. anxiety), CNS inhibition (e.g. somnolence), rhinitis, vision changes, dizziness/vertigo, tinnitus, signs and symptoms of UTI, rash. Ocular hyperaemia, eye irritation, fibrosis, miosis, mydriasis.

Toxicity

LD₅₀=10 mg/kg (orally in dogs).

Selective COX-2 inhibitors have been associated with increased risk of serious cardiovascular events (e.g. myocardial infarction, stroke) in some patients. Current data is insufficient to assess the cardiovascular risk of flurbiprofen. Flurbiprofen may increase blood pressure and/or cause fluid retention and edema. Use caution in patients with fluid retention or heart failure. Risk of GI toxicity including bleeding, ulceration and perforation. Risk of direct renal injury, including renal papillary necrosis. Anaphylactoid and serious skin reactions (e.g. exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis) may occur. Common adverse events include abdominal pain, constipation, diarrhea, dyspepsia, flatulence, GI bleeding, GI perforation, nausea, peptic ulcer, vomiting, renal function abnormalities, anemia, dizziness, edema, liver function test abnormalities, headache, prolonged bleeding time, pruritus, rash, tinnitus. Although rarely documented in the case of flurbiprofen, oral propionic acid derivatives have been associated with a relatively high frequency of allergic reactions.

Precaution

Patients with known CV disease or risk factors for CV disease, fluid retention. Hepatic and renal impairment. Lactation.

Interaction

Reduced antihypertensive effect of ACE inhibitors, angiotensin II receptor antagonists and β-blockers. Slight reduction in blood glucose concentration in patients with DM receiving certain antidiabetic agents (e.g. glyburide, metformin). Reduced diuretic effect of furosemide and thiazides. May increase toxicity of lithium and methotrexate. May increase risk of bleeding with antiplatelets, anticoagulants, SSRIs, corticosteroids.

Volume of Distribution

• 14 L [Normal Healthy Adults]
• 12 L [Geriatric Arthritis Patients]
• 10 L [End Stage Renal Disease Patients]
• 14 L [Alcoholic Cirrhosis Patients]
• 0.12 L/kg

Elimination Route

Fluribiprofen is rapidly and almost completely absorbed following oral administration. Peak plasma concentrations are reached 0.5 - 4 hours after oral administration.

Half Life

R-flurbiprofen, 4.7 hours; S-flurbiprofen, 5.7 hours

Elimination Route

Flurbiprofen is poorly excreted into human milk. Following dosing with flurbiprofen, less than 3% of flurbiprofen is excreted unchanged in the urine, with about 70% of the dose eliminated in the urine as parent drug and metabolites. Renal elimination is a significant pathway of elimination of flurbiprofen metabolites.

Pregnancy & Breastfeeding use

Pregnancy Category C. Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Contraindication

Known hypersensitivity to flurbiprofen, history of asthma, urticaria, or allergic-type reactions precipitated by aspirin or other NSAIDs, NSAID-related history of GI bleeding or perforation, treatment of perioperative pain in the setting of CABG surgery. Pregnancy (3rd trimester) and lactation.

Acute Overdose

Symptoms: Headache, nausea, vomiting, epigastric pain, GI bleeding, diarrhoea, disorientation, excitation, coma, drowsiness, dizziness, tinnitus, fainting and occasionally convulsions, acute renal failure and liver damage.

Management: Supportive and symptomatic treatment. Admin activated charcoal w/in 1 hr after ingestion. In adults, gastric lavage should be considered.

Storage Condition

Store between 15-25° C.
