Itamidol (Diclofenac)

Diclofenac, the active ingredient in Itamidol, is a nonsteroidal anti-inflammatory drug presented as a topical formulation for cutaneous use. It provides relief of mild to moderate pain and reduces inflammation in musculoskeletal conditions and localized swelling. The product is formulated for external application to the skin, allowing targeted action at the site of pain without systemic exposure.

GNH USA supplies Itamidol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on quality and regulatory compliance.

Diclofenac acts locally on inflamed tissues to alleviate pain and swelling in several musculoskeletal and dermatologic conditions.

- Mild to moderate musculoskeletal pain: reduces pain intensity and improves function. - Localized joint inflammation (e.g., osteoarthritis of the knee): diminishes swelling and stiffness. - Superficial soft‑tissue injuries (sprains, strains): provides topical analgesia and anti‑inflammatory effect. - Post‑operative incision discomfort: eases localized pain at the surgical site. - Dermatologic inflammatory lesions (e.g., erythema, edema): helps reduce redness and swelling.

Topical diclofenac may cause local and systemic adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Skin irritation at the application site. - Burning or stinging sensation. - Pruritus. - Dryness of the treated area.

Serious or Rare Side Effects: - Allergic contact dermatitis. - Stevens‑Johnson syndrome or other severe cutaneous reactions. - Systemic NSAID effects such as gastrointestinal ulceration, hepatotoxicity, or renal impairment.

When using Itamidol, consider the following safety measures.

- Assess skin integrity: avoid application on broken or infected skin. - Limit use to the prescribed area: do not cover with occlusive dressings unless directed. - Monitor for systemic NSAID effects: especially in patients with cardiovascular or renal disease. - Avoid concurrent use with other topical NSAIDs: to reduce cumulative exposure. - Store below 25°C: keep in original packaging, protect from moisture and light.

Diclofenac can interact with other medicines; some combinations should be avoided while others require monitoring.

Major Interactions (Avoid): - Concurrent systemic NSAIDs (e.g., ibuprofen, naproxen): increased risk of gastrointestinal bleeding. - Anticoagulants (warfarin, direct oral anticoagulants): heightened bleeding risk. - Lithium therapy: diclofenac may raise lithium plasma concentrations.

Moderate Interactions (Monitor Closely): - ACE inhibitors or ARBs: potential impact on renal function. - Diuretics: may reduce renal perfusion when combined. - Methotrexate: diclofenac can decrease clearance, increasing toxicity risk.
