What is Volfenac and What Class of Medicine Does It Belong To?

Volfenac is a pharmaceutical preparation whose active component is the drug substance Diclofenac, a member of the major therapeutic group known as Nonsteroidal Anti-inflammatory Drugs (NSAIDs). This classification identifies it as a synthetic compound derived chemically from phenylacetic acid.


As a single-ingredient product, Volfenac’s identity is directly tied to Diclofenac, which is typically provided as a soluble salt, such as Diclofenac sodium or potassium, to enhance stability and absorption. Diclofenac is categorized as an essential medicine, reflecting its established role as an anti-inflammatory and analgesic agent globally. This status indicates the medicine is considered important for managing public health needs related to pain and inflammation.

Composition, Forms, and General Therapeutic Purpose

The fundamental purpose of Volfenac is to provide symptomatic relief from pain, inflammation, and fever by targeting the body's inflammatory response pathways. The active substance, Diclofenac, operates primarily as a Cyclooxygenase (COX) inhibitor, limiting the synthesis of prostaglandins, which are chemical messengers responsible for driving these specific symptoms. The compound is recognized for its potent anti-inflammatory action.


Volfenac is manufactured to accommodate various therapeutic needs and is thus available in multiple dosage forms, including oral preparations like tablets and capsules, as well as forms for targeted or rapid-action administration, such as topical gels and solutions for injection. Diclofenac is an established compound for the general management of acute painful conditions. This means the medication is used to help reduce the intensity of various types of acute discomfort, such as the general aches associated with musculoskeletal strain. The intended therapeutic effect is a reduction in swelling and tenderness, a decrease in pain intensity, and the potential to normalize elevated body temperature.

Pediatric Use Safety and efficacy are not established for most uses in children under 12 years of age; eligibility may begin at 12 or 14 years, depending on the specific formulation [3.4].
Older Adults Use requires caution due to increased risk of gastrointestinal and kidney issues. Avoid use in older adults with cardiovascular/renal risk factors [3.5].
Pregnancy Contraindicated from 30 weeks gestation onward; use should be limited between 20 and 30 weeks [3.2].
Organ Impairment Caution is advised in mild to moderate hepatic or renal impairment [3.7].

Eligibility is limited or restricted for those with significant cardiovascular risk factors, and the safety status during breastfeeding is undetermined [2.7], [3.4].

What should I know about interactions with other medicines?

The official interaction profile for Volfenac (Diclofenac) is defined by documented pharmacokinetic and pharmacodynamic relationships with other medicinal products and substances. High-level restrictions include the formal contraindication for use in the perioperative setting of Coronary Artery Bypass Graft (CABG) surgery. Co-administration with other Nonsteroidal Anti-inflammatory Drugs (NSAIDs), including aspirin, is officially not recommended due to a synergistically increased risk of serious gastrointestinal adverse events.

Pharmacokinetic interactions are formally documented with potent inhibitors of the CYP2C9 enzyme, such as Voriconazole. This concurrent use reduces metabolic clearance, resulting in a documented peak plasma concentration ( C max) increase of 114% and an area under the curve ( AUC) increase of 78% for Diclofenac. Furthermore, Volfenac reduces the renal clearance of Lithium and Methotrexate, which elevates plasma levels of these co-administered drugs.

Pharmacodynamic interactions include an increased risk of bleeding when combined with Anticoagulants (like Warfarin) and Antiplatelet Agents. Volfenac may also diminish the antihypertensive and natriuretic effects of medicines like ACE Inhibitors, ARBs, and Diuretics. This combination carries a specific caution for elderly, volume-depleted, or renal-impaired patients due to a heightened risk of renal function deterioration. Finally, the co-administration of Alcohol is noted to increase the risk of serious gastrointestinal problems.

Mechanism of Action

How Volfenac Works: Mechanism of Action

Key Target: Non-Selective Cyclooxygenase Inhibition

Volfenac primarily acts by non-selectively inhibiting the Cyclooxygenase (COX-1 and COX-2) enzymes. This enzyme inhibition blocks the initial molecular step in the arachidonic acid cascade, preventing the conversion of arachidonic acid into various inflammatory mediators.


Pathway Effect: Suppression of Prostaglandin Synthesis

The suppression of enzyme activity reduces the production of prostaglandins ( PGE2 and PGI2) and thromboxanes ( TXA2). This systemic reduction of key mediators is the core pathway effect, decreasing the concentration of molecules involved in nociception and vascular permeability.


Physiological Outcome: Modulating Nociceptor and Vascular Responses

At the physiological level, the reduction of PGE2 results in a decreased sensitization threshold of peripheral nociceptors and the modulation of local vascular responses. Furthermore, the central action results in the reduction of the hypothalamic temperature set-point during states of pyresis.

Dosage and Administration Information

Volfenac is administered through several official routes, including oral tablets, topical gels, rectal suppositories, and parenteral solutions for intramuscular (IM) and intravenous (IV) injection. The selection of the route depends on the immediate context, although oral administration is the most common regimen for ongoing use. General clinical principles suggest utilizing the lowest effective dose for the shortest duration required, consistent with general NSAID guidance.

Administration Scope Usage Principle
Oral Forms (Dosing) Doses for chronic conditions like rheumatoid arthritis typically range from 100 mg to 150 mg per day. The maximum recommended daily dose for most oral uses is 150 mg.
Oral Forms (Frequency) Frequency varies by formulation: extended-release tablets are often administered once daily, while immediate-release or delayed-release forms require divided dosing, typically two or three times daily.
Oral Forms (Handling) Specific oral forms, such as delayed-release or extended-release tablets, must be swallowed whole to ensure the controlled release profile is maintained and are not to be crushed or chewed.

The timing of oral administration is form-dependent; while many oral tablets can be taken with food, certain rapid-action formulations intended for conditions like acute migraine are often taken on an empty stomach. Parenteral use is subject to strict duration limits: the use of both intravenous and intramuscular injection is generally restricted to no more than two days for the initial management of pain, after which the regimen typically transitions to an oral or rectal form. Dosage adjustments for specific populations, such as older adults, often involve initiating treatment with the lowest possible dose. If a dose is missed, guidelines typically suggest omitting the missed dose if it is near the time of the next scheduled dose, and double dosing is prohibited.

Recent Clinical Evidence

Research evidence / Overview of Studies for Volfenac

Evidence for Use in Osteoarthritis

Research exploring Volfenac for joint conditions like osteoarthritis (OA) has been primarily structured around Randomized Controlled Trials (RCTs) and Meta-analyses. These studies were used in research exploring how symptoms change over time, and were designed to monitor outcomes related to physical discomfort and daily functioning in adult patients. Studies in this area examined specific endpoints, such as changes in patient-reported pain intensity and measurable shifts in physical function scales, which are designed to track activity level.

Trials documented measured changes in patient-reported pain intensity during the observation periods. Observed data also included numerical shifts in validated scores, reflecting recorded changes in function and stiffness metrics within the study groups. Importantly, some findings from meta-analyses described a degree of heterogeneity when comparing measurements across different Volfenac formulations.

Evidence for Acute Pain Management

Research exploring Volfenac for conditions associated with acute or disruptive episodes is based on short-term, randomized, placebo-controlled trials. These studies focused on episodes where symptoms become more noticeable, and they used highly specific analgesic metrics to monitor responses over defined time intervals.

Trials documented measurable patterns related to the time to the onset of reported symptom change and recorded changes in peak pain intensity in the hours following administration. Studies also reported numerical metrics related to the reported patterns related to the use of rescue medication in the observed groups.

Areas of Research Uncertainty

The research exploring short-term symptom changes, while available for acute events, leaves long-term effects not fully established for chronic conditions, where follow-up durations were limited in the core efficacy trials. Furthermore, data for certain groups remain insufficient, particularly for pediatric populations, and evidence describing comparative effectiveness against other treatments is sometimes lacking in large-scale studies.
