Introduction

Fenaaf Tablet 100 mg is an oral non-steroidal anti-inflammatory drug (NSAID) with marked anti-inflammatory and analgesic properties used to treat osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It is reported to have a higher anti-inflammatory action or at least comparable effects than conventional NSAIDs in double-blind studies . Fenaaf Tablet 100 mg potently inhibits the cyclo-oxygenase enzyme (COX) that is involved in the synthesis of prostaglandins, which are inflammatory mediators that cause pain, swelling, inflammation, and fever. Fenaaf Tablet 100 mg belongs to BCS Class II as it possesses poor aqueous solubility . It displays high permeability to penetrate into synovial joints where in patients with osteoarthritis and related conditions, the loss of articular cartilage in the area causes joint pain, tenderness, stiffness, crepitus, and local inflammation . Fenaaf Tablet 100 mg is also reported to be effective in other painful conditions such as dental and gynaecological conditions . In 1991, aceclofenac was developed as an analog of a commonly prescribed NSAID, Diclofenac, via chemical modification in effort to improve the gastrointestinal tolerability of the drug. It is a more commonly prescribed drug in Europe.

Uses

Fenaaf Tablet 100 mg is indicated for the relief of pain and inflammation in osteoarthritis, rheumatoid arthritis and ankylosing spondylitis.

Associated Conditions

Ankylosing Spondylitis (AS)
Osteoarthritis (OA)
Rheumatoid Arthritis

Pharmacodynamics

Fenaaf Tablet 100 mg is a NSAID that inhibits both isoforms of COX enzyme, a key enzyme involved in the inflammatory cascade. COX-1 enzyme is a constitutive enzyme involved in prostacyclin production and protective functions of gastric mucosa whereas COX-2 is an inducible enzyme involved in the production of inflammatory mediators in response to inflammatory stimuli. Fenaaf Tablet 100 mg displays more selectivity towards COX-2 (IC50 of 0.77uM) than COX-1 (IC50 of >100uM), which promotes its gastric tolerance compared to other NSAIDs. The primary metabolite, 4'-hydroxyaceclofenac, also minimally inhibits COX-2 with IC50 value of 36uM . Although the mode of action of aceclofenac is thought to mainly arise from the inhibition of synthesis of prostaglandins (PGE2), aceclofenac also inhibits the production of inflammatory cytokines, interleukins (IL-1β, IL-6), and tumor necrosis factors (TNF) . It is also reported that aceclofenac also affects the cell adhesion molecules from neutrophils [A19763]. Fenaaf Tablet 100 mg also targets the synthesis of glycosaminoglycan and mediates chrondroprotective effects .

Mechanism of Action

Through COX-2 inhibition, aceclofenac downregulates the production of various inflammatory mediators including prostaglandin E2 (PGE2), IL-1β, and TNF from the arachidonic acid (AA) pathway. Inhibition of IL-6 is thought to be mediated by diclofenac converted from aceclofenac . Suppressed action of inflammatory cytokines decreases the production of reactive oxygen species. Fenaaf Tablet 100 mg is shown to decreased production of nitrous oxide in human articular chondrocytes . In addition, aceclofenac interferes with neutrophil adhesion to endothelium by decreasing the expression of L-selectin (CD62L), which is a cell adhesion molecule expressed on lymphocytes . Fenaaf Tablet 100 mg is proposed to stimulate the synthesis of glycosaminoglycan in human osteoarthritic cartilage which may be mediated through its inhibitory action on IL-1 production and activity . The chrondroprotective effects are generated by 4'-hydroxyaceclofenac which suppresses IL-1 mediated production of promatrix metalloproteinase-1 and metalloproteinase-3 and interferes with the release of proteoglycan from chrondrocytes .

Absorption

Fenaaf Tablet 100 mg is rapidly and completely absorbed from the gastrointestinal tract and circulates mainly as unchanged drug following oral administration. Peak plasma concentrations are reached around 1.25 to 3 hours post-ingestion, and the drug penetrates into the synovial fluid where the concentration may reach up to 60% of that in the plasma . There is no accumulation in regular dosing, with similar maximum plasma concentration (Cmax) and time to reach peak plasma concentration (Tmax) after single and multiple doses .

Volume of Distribution

The volume of distribution is approximately 25 L .

Protein Binding

It is reported to be highly protein-bound (>99%) .

Route of Elimination

The main route of elimination is via the urine where the elimination accounts for 70-80% of clearance of the drug . Approximately two thirds of the administered dose is excreted via the urine, mainly as glucuronidated and hydroxylated forms of aceclofenac . About 20% of the dose is excreted into feces .

Half Life

The mean plasma elimination half-life is approximately 4 hours .

Clearance

The mean clearance rate is approximately 5 L/h .

Toxicity

Some common adverse effects include gastro-intestinal disorders (dyspepsia, abdominal pain, nausea), rash, ruber, urticaria, symptoms of enuresis, headache, dizziness, and drowsiness . Oral LD50 value in rats is 130 mg/kg .

Food Interactions

Take with or without food.

Dosage

Extended release tablet: The recommended dose in adults is one 200 mg Fenaaf Tablet 100 mg tablet daily or as prescribed by the physician.
