Capsaicin cream/patches

Capsaicin topical creams and patches provide localized pain relief by leveraging capsaicin—the active component of chili peppers—to desensitize pain-transmitting nerve fibers. With repeated use, capsaicin reduces the concentration of substance P, a neuropeptide involved in pain signaling, resulting in sustained analgesic benefit.

Capsaicin products are widely used for chronic musculoskeletal and neuropathic pain, offering a non-systemic, non-opioid treatment option suitable for long-term management when used correctly.

Key Benefits

• Non-opioid, non-systemic pain relief

• Effective for chronic and neuropathic pain conditions

• Available in both cream and patch formulations

• Suitable for repeated use with proper adherence

Common Indications

• Osteoarthritis pain (knee, hand, joint pain)

• Peripheral neuropathy (including diabetic neuropathy)

• Postherpetic neuralgia

• Muscle and joint pain

• Back and neck pain

Mechanism of Action

Capsaicin activates TRPV1 receptors on nociceptive neurons, initially causing a warming or burning sensation. With continued exposure, these neurons become functionally desensitized, leading to reduced pain transmission and longer-lasting relief.
