👨‍⚕️ Doctor's Practical Tips

Evidence-based practical advice from experienced clinicians

1
Apply this medicine to clean, dry skin and wash your hands afterward to avoid spreading it to other areas.
2
Do not use this medicine on broken skin or near mucous membranes to prevent irritation and systemic absorption.
3
Avoid covering the treated area with tight bandages or applying heat, as this can increase absorption and side effects.
4
If you are using this medicine for arthritis, combine it with gentle exercises and physical therapy for better results.
5
Discontinue use and consult a doctor if you experience severe skin reactions or signs of systemic effects like dizziness or nausea.
6
Inform your doctor if you are taking blood thinners or other NSAIDs, as the risk of bleeding may increase.

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionDiclofenac and lidocaine are absorbed through intact skin. The extent of systemic absorption depends on the surface area, duration of application, and skin condition. Typically, only a small fraction of the applied dose reaches systemic circulation compared to oral administration.
DistributionAfter absorption, diclofenac is highly bound to plasma proteins and distributes into synovial fluid and inflamed tissues. Lidocaine distributes widely into tissues, with a volume of distribution of about 1.1 to 2.1 L/kg in adults.
Protein BindingDiclofenac is approximately 99% bound to plasma proteins, primarily albumin. Lidocaine is about 60-80% bound to plasma proteins, including alpha-1-acid glycoprotein and albumin.
MetabolismDiclofenac is metabolized in the liver by cytochrome P450 enzymes, mainly CYP2C9, to several metabolites. Lidocaine is metabolized in the liver by CYP3A4 and CYP1A2 to monoethylglycinexylidide (MEGX) and glycinexylidide (GX), which have some activity.
Half-LifeThe elimination half-life of diclofenac is approximately 1-2 hours. The elimination half-life of lidocaine is about 1.5-2 hours.
ExcretionDiclofenac metabolites are excreted primarily in urine (about 65%) and bile/feces (about 35%). Lidocaine metabolites are excreted mainly in urine.
BioavailabilityThe systemic bioavailability of diclofenac from topical gel is approximately 6% relative to oral dosing. The bioavailability of lidocaine from topical application is not well established but is considered low.
Onset of ActionPain relief typically begins within 30 minutes to 1 hour after application due to the lidocaine component. The anti-inflammatory effect of diclofenac may take longer, often several hours to days, to become noticeable.
Peak Plasma TimePeak plasma concentrations of diclofenac after topical application are generally reached within 1-4 hours. For lidocaine, peak levels are reached within 1-2 hours.
Duration of ActionThe numbing effect of lidocaine lasts for about 1-2 hours. The anti-inflammatory and analgesic effects of diclofenac can last for several hours, often requiring application 3-4 times daily.

How It Works

This medicine combines two active ingredients with complementary mechanisms. Diclofenac is a nonsteroidal anti-inflammatory drug that reversibly inhibits cyclooxygenase enzymes (COX-1 and COX-2), leading to decreased production of prostaglandins, which are mediators of inflammation and pain. Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels on nerve membranes, preventing the initiation and conduction of nerve impulses, thereby producing local numbness. Together, they reduce both inflammation and pain perception in the applied area.

Mechanism Steps

1
Diclofenac inhibits cyclooxygenase: Diclofenac binds to and reversibly inhibits the COX-1 and COX-2 enzymes, blocking the conversion of arachidonic acid to prostaglandin H2.
2
Reduced prostaglandin synthesis: Decreased prostaglandin levels lead to less inflammation, swelling, and sensitization of pain receptors.
3
Lidocaine blocks sodium channels: Lidocaine diffuses into nerve membranes and binds to voltage-gated sodium channels, preventing sodium influx and nerve impulse conduction.
4
Local anesthesia: The blockade of sodium channels results in reversible loss of sensation in the applied area, providing rapid pain relief.
