Property Description
Active ingredient Aceclofenac
Form Film-coated Tablet (Comprimido)
Pharmacological class Non-Steroidal Anti-Inflammatory Drug (NSAID)
Common use Relief of pain and inflammation
Origin Synthetic (Phenylacetic Acid Derivative)

1. Defining Aceclofenac Generis as a Pharmaceutical Entity

Aceclofenac Generis 100 mg Comprimidos is a synthetic, single-component medication containing Aceclofenac as its sole active ingredient. It is systematically classified as a Non-Steroidal Anti-Inflammatory Drug (NSAID), belonging to the chemical subgroup of acetic acid derivatives. The drug is presented as a film-coated tablet (comprimido) of 100 mg, a solid dosage form designed for reliable oral administration. Aceclofenac is chemically defined as a phenylacetic acid derivative, confirming its identity as a standardized, prescription-only therapeutic agent.


2. Aceclofenac's Place Within the NSAID Class and Utility

The core purpose of this medication is to provide both analgesic (pain-relieving) and anti-inflammatory effects. Its mechanism is focused on inhibiting the cyclo-oxygenase (COX) enzyme, thus reducing the production of inflammatory mediators, specifically prostaglandins. Aceclofenac is characterized by its anti-inflammatory profile and acts as a preferential COX-2 inhibitor, a distinction that focuses its action toward the acute inflammatory process. This provides the utility of the drug for managing symptoms where pain is intrinsically linked to active inflammation, such as chronic joint discomfort.


3. General Therapeutic Utility and Presentation

The film-coated tablet form facilitates non-invasive oral administration and accurate dosing, ensuring the required amount of Aceclofenac reaches the bloodstream effectively. The drug is used for the management of inflammatory pain and swelling across various musculoskeletal conditions. The overall benefit of this product is concentrated on systemic symptomatic relief by effectively addressing the underlying inflammatory component that causes pain and swelling.

Clinically Significant Risks and Restrictions

Serious Adverse Reactions: All NSAIDs, including aceclofenac, carry a risk of serious, potentially fatal, gastrointestinal (GI) events such as bleeding, ulceration, and perforation. There is also an increased risk of serious arterial thrombotic events, including myocardial infarction (heart attack) and stroke, with the risk being higher with prolonged use and high doses. Severe hypersensitivity reactions, including anaphylactic shock, and very rare but severe skin reactions require immediate discontinuation of treatment.

Contraindications and Special Populations: This medicine is contraindicated in patients with active or recurrent peptic ulcer/haemorrhage, severe liver or kidney failure, established congestive heart failure (NYHA class II–IV), ischaemic heart disease, or in the last trimester of pregnancy. Elderly patients are at an increased risk of severe adverse effects, particularly GI bleeding. The use of the lowest effective dose for the shortest duration necessary is advised to minimise risk. It is not recommended for use in children and adolescents under 18 years of age.

Overdose and Emergency Response

Overdose and when to seek help

The following information details the officially documented manifestations and required emergency actions in the event of an overdose, as described in government regulatory documents.

Documented Overdose Manifestations

Overdose may present with common clinical signs, including nausea, vomiting, abdominal pain, and central nervous system effects such as headache, dizziness, and drowsiness. Severe or life-threatening outcomes formally documented in regulatory labeling include the potential for acute renal failure, hepatic damage, and serious gastrointestinal bleeding or ulceration. In high-risk patients, particularly the elderly, the risk of severe gastrointestinal complications is increased.


Mandated Emergency Response

Immediate medical attention must be sought for any suspected overdose. Due to the risk of severe organ toxicity, emergency services should be contacted for life-threatening symptoms such as convulsions, significant bleeding, or signs of organ failure. No specific antidote is known for Aceclofenac toxicity, which limits management to supportive and symptomatic treatment.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documents classify interactions with Aceclofenac based on the resulting clinical outcome, ranging from contraindicated combinations to those requiring enhanced monitoring.

Contraindicated or Not Recommended Combinations

  • Other NSAIDs (including COX-2 selective inhibitors): Co-administration should be avoided due to an increased incidence of adverse effects, particularly gastrointestinal risks.
  • Acetylsalicylic Acid (Aspirin): Use at analgesic or anti-inflammatory doses is generally not recommended.

Exposure-Modifying Interactions

Aceclofenac is documented to increase the plasma concentrations of certain medicines by inhibiting their renal clearance or elimination:

  • Lithium and Digoxin
  • Methotrexate: May cause decreased elimination, potentially leading to increased toxicity, especially if administered within 24 hours of each other.

Pharmacodynamic and Efficacy Interactions

  • Anticoagulants (e.g., Warfarin): The effects of these medicines may be enhanced, increasing the risk of bleeding; close monitoring is required.
  • Diuretics and Antihypertensives (e.g., ACE Inhibitors): Aceclofenac may reduce their therapeutic effect and increase the risk of deterioration of renal function.
  • Corticosteroids, SSRIs, and Antiplatelet Agents: These combinations increase the risk of gastrointestinal ulceration or bleeding.
  • Mifepristone: Aceclofenac should not be used for 8–12 days following mifepristone administration to prevent a reduction in its effect.

Population-Specific Notes

  • The Elderly: Elderly patients receiving concomitant interacting medications, such as Corticosteroids or Anticoagulants, have an officially documented increased risk of serious adverse reactions.

Mechanism of Action

Aceclofenac is classified as a non-steroidal anti-inflammatory drug (NSAID). Its primary molecular action is the binding and inhibition of the enzyme cyclooxygenase (COX). Aceclofenac acts as a preferential inhibitor of the COX-2 isoform over COX-1, though inhibition of both contributes to its overall pharmacodynamic profile.

The COX enzyme catalyzes the conversion of arachidonic acid into prostanoids, including prostaglandins and thromboxanes. By inhibiting COX activity, aceclofenac disrupts the prostanoid synthesis cascade. This disruption results in the decreased generation of prostaglandins, which are key biochemical messengers involved in local inflammatory responses.

Aceclofenac also mediates the function of specific inflammatory cytokines within the cellular environment. This involves the modulation of signaling pathways associated with mediators such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha). The combined effect of COX inhibition and cytokine modulation alters the biochemical signaling that initiates and sustains inflammatory physiological processes.

Dosage and Administration Information

The use of Aceclofenac Generis 100 mg Comprimidos follows standardized administration protocols focused on protocol and precise dosage. This medication is designated for oral administration as a 100 mg film-coated tablet. The recommended total daily intake for adults is 200 mg, which is typically administered as two separate 100 mg doses, one taken in the morning and one in the evening.

Administration Feature Instruction
Dosing Schedule 100 mg twice daily (morning and evening)
Administration Method Tablet must be swallowed whole with a sufficient quantity of liquid, and not crushed or chewed.
Timing with Meals Taken preferably with or after food; food affects the rate, but not the overall extent, of absorption.
Duration Principle Use the lowest effective dose for the shortest duration necessary to control symptoms.

The duration of treatment is typically re-evaluated periodically based on symptomatic relief, aligning with the principle of minimal necessary exposure. Dosage adjustments are specified for specific patient groups: for individuals with hepatic impairment, an initial daily dose of 100 mg is suggested. Furthermore, the medication is not recommended for use in the paediatric population due to a lack of sufficient clinical data. No general modification to the dose or frequency is considered necessary for the elderly population.

Recent Clinical Evidence

Research evidence / Overview of studies for Aceclofenac Generis 100 mg Comprimidos

This overview summarizes the clinical research that has examined Aceclofenac Generis 100 mg Comprimidos. It focuses on the types of studies conducted, the outcomes measured, and areas where evidence may be limited, using information derived only from official regulatory and scientific sources.


Evidence for Use in Osteoarthritis

Research for this condition was studied for how it was associated with outcomes related to physical discomfort and daily functioning or activity level in patients. Studies utilized short-term Randomized Controlled Trials (RCTs), where results were compared against an inactive treatment or another established medicine. Larger observational studies have also explored patterns of use over longer periods.

These trials primarily examined changes in outcomes related to systemic or functional imbalance, such as scores on the Visual Analogue Scale (VAS) for pain intensity and the WOMAC scale for functional ability. The studies monitored adult populations with clinically diagnosed osteoarthritis. In comparing the measured changes, findings describe patterns observed in the studies. However, when the findings from multiple studies were pooled together in large reviews, data show patterns related to statistical heterogeneity, meaning the measured results sometimes varied across different trials. This, combined with follow-up durations were limited to short periods, means certainty is characterized as moderate.


Evidence for Use in Rheumatoid Arthritis

Aceclofenac Generis was evaluated in comparative clinical studies focusing on conditions involving periods of heightened symptoms in adults with rheumatoid arthritis. The research examined short-term symptom patterns over defined time intervals, typically lasting only a few weeks. The primary outcomes studied focused on outcomes capturing phases of heightened symptom activity, such as joint pain and measured swelling. Studies report how symptoms evolved in the observed populations and described measured changes. There is limited information for long-term outcomes that would provide context on the effects on disease progression over many years.


Long-Term Studies and Duration of Follow-Up

While comparative efficacy trials often measure outcomes over weeks, some observational settings evaluating daily-life functioning have monitored patient experiences over several months. These extended studies are valuable for evidence contributes to understanding symptom patterns during regular use. However, high-quality, long-term randomized evidence is generally limited for chronic pain medications of this class, meaning long-term effects are not fully established.


What is Still Uncertain About the Research Base

In reviews of studies for osteoarthritis, findings were mixed regarding the consistency of results across different trials. Overall, key research limitations include the fact that follow-up durations were limited in many controlled studies, meaning data are still emerging for long-term outcomes. Furthermore, comparative evidence is lacking for some complex patient subgroups, and evidence quality may vary across the scientific landscape. Evidence highlights what is known — and what is still uncertain.
