Diclofenac Analysis: Why You Should Verify the Compliance of Your NSAIDs

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that is essential for relieving inflammatory and rheumatic pain. Because it is so widely used, it is unfortunately a frequent target of counterfeiting networks. For healthcare professionals, distributors, and patients, laboratory analysis of diclofenac has become a crucial step in ensuring that the medication taken is indeed the one prescribed and that it meets therapeutic dosage requirements.

The Challenges of Laboratory Analysis: Beyond Appearances

When a medication is purchased outside official channels, particularly at an online pharmacy, it is impossible to guarantee its quality through a simple visual inspection. The blister pack may appear authentic, but the contents may be completely different. Testing for diclofenac helps answer two critical questions:

Does the active ingredient contain diclofenac? Some counterfeit products contain no trace of diclofenac, consisting only of inert excipients (placebos) or, worse, different active ingredients.

Is the dosage correct? An underdosed tablet will be ineffective against inflammation, while an overdose drastically increases the risk of side effects, particularly severe gastrointestinal or renal complications, which are characteristic of improper use of NSAIDs.

The reference method: HPLC-UV chromatography

Pharmanalyse uses High-Performance Liquid Chromatography (HPLC-UV), the gold standard in the pharmaceutical industry for quality control.

Why is this method essential?

Analytical precision: It allows the diclofenac molecule to be isolated from any other compounds present in the tablet.

Precise quantification: It measures the concentration of the active ingredient to the nearest milligram. This control ensures that the dose ingested corresponds exactly to the therapeutic dose required for safe treatment.

Impurity Detection: This analysis also helps identify any contaminants (solvents, synthesis residues) introduced during unregulated, clandestine manufacturing.

Who should have a diclofenac test performed in a laboratory?

Access to laboratory expertise is no longer limited to large pharmaceutical companies. Pharmanalyse makes this testing available to everyone:

Importers and distributors: Before any batch is placed on the market, testing for diclofenac is an essential legal safeguard against the distribution of non-compliant products.

Health and customs authorities: To quickly identify suspicious shipments and protect the public.

Individuals: To eliminate any doubts about the origin of a medication purchased online or through questionable channels, and thereby protect their health.

Science as the Only Guarantee of Safety

Counterfeiting is a silent threat, but science is a clear and effective defense. Don’t let doubt compromise your health. By opting for rigorous testing, you’re choosing certainty and transparency over the illusion of compliant packaging.
