Motusol Max (Diclofenac Diethylamine)

• Diclofenac diethylamine topical NSAID acts on inflammatory pathways to provide relief in several musculoskeletal and soft‑tissue conditions.
• Musculoskeletal pain: Reduces pain and swelling in muscles, tendons and joints affected by overuse or minor injury.
• Sprains and strains: Alleviates inflammation and discomfort associated with ligament or muscle tears, supporting faster functional recovery.
• Osteoarthritis of superficial joints: Provides localized anti‑inflammatory effect to improve joint mobility and lessen pain in surface joints such as the knee or hand.

• Diclofenac diethylamine penetrates the skin and inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes in peripheral tissues. By blocking these enzymes, the conversion of arachidonic acid to prostaglandins is reduced, leading to decreased synthesis of inflammatory mediators that cause pain, swelling and redness at the site of application. The topical route concentrates the effect where needed while limiting systemic drug levels, which helps to maintain a favorable safety profile compared with oral NSAIDs.

Topical diclofenac diethylamine may cause local and, rarely, systemic adverse reactions.

Common Side Effects

• Skin irritation: Redness, itching or burning at the application site.
• Pruritus: Mild itching without rash.
• Dryness: Localized dry skin where gel is applied.
• Sensation of warmth: Transient feeling of warmth or tingling.

Serious or Rare Side Effects

• Allergic dermatitis: Severe rash, swelling, or blistering indicating hypersensitivity.
• Systemic NSAID effects: Gastrointestinal ulceration or bleeding if significant absorption occurs.
• Cardiovascular events: Rare increase in blood pressure or thrombotic risk in susceptible individuals.

When using Motusol Max, several precautions should be observed to ensure safe and effective therapy.

• Application area: Apply a thin layer only to intact, unbroken skin of the affected region.
• Frequency: Do not exceed the recommended number of applications per day as advised by the prescriber.
• Concomitant NSAIDs: Avoid using other topical or systemic NSAIDs simultaneously to reduce risk of additive toxicity.
• Medical conditions: Use with caution in patients with a history of asthma, urticaria or known NSAID hypersensitivity.
• Pregnancy and lactation: Consult a healthcare professional before use during pregnancy or while breastfeeding.
• Store at room temperature: Keep the product below 25 °C in the original packaging, protected from moisture and direct sunlight.

Diclofenac diethylamine can interact with other medicines; awareness of these interactions helps prevent reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Anticoagulants: Increased risk of bleeding when combined with warfarin or other blood thinners.
• Other NSAIDs: Additive gastrointestinal toxicity and renal impairment when used with oral or topical NSAIDs.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or diuretics: May diminish renal function, requiring monitoring of kidney parameters.
• Lithium: Diclofenac can raise lithium serum levels, necessitating dosage adjustment.
• Methotrexate: Potential for increased methotrexate toxicity due to reduced renal clearance.
