Lignogesic Gel is a topical analgesic formulation combining multiple active ingredients to provide effective relief from musculoskeletal pain and inflammation. It contains Mephenesin (10% w/w), a centrally acting muscle relaxant that alleviates muscle spasms; Diclofenac (1.16% w/w), a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain by inhibiting cyclooxygenase enzymes; Lidocaine (2% w/w), a local anesthetic that provides rapid numbing and pain relief; Methyl Salicylate (10% w/w), a counterirritant that produces a warming sensation to distract from deeper musculoskeletal pain; Linseed Oil (3% w/w), which possesses anti-inflammatory and skin conditioning properties; and Menthol (5% w/w), which imparts a cooling effect that soothes irritated tissues and enhances analgesic efficacy. This synergistic combination targets pain, inflammation, and muscle stiffness associated with conditions such as strains, sprains, arthritis, and backache. Lignogesic Gel is intended for external use only and should be applied to the affected area with gentle massage, avoiding broken skin and mucous membranes. It is contraindicated in patients with hypersensitivity to any component. Use under medical supervision is advised, especially in pregnant or lactating women. The formulation offers a multi-mechanistic approach to managing localized musculoskeletal discomfort, improving patient mobility and comfort.
