Opsor (Salicylic Acid)

Salicylic acid, the active ingredient in Opsor, is a keratinocyte‑targeting agent presented as a topical formulation for dermatological use. It is employed to treat hyperkeratotic skin conditions and is suitable for adult patients. GNH USA supplies Opsor as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Opsor acts on keratinocyte proliferation pathways and is indicated for several dermatologic conditions. - Acne vulgaris: helps reduce comedones and inflammatory lesions. - Psoriasis plaques: softens and facilitates removal of thickened plaques. - Seborrheic keratosis: aids in gradual exfoliation of lesions.

Salicylic acid may cause local skin reactions, most of which are mild and reversible.

Common Side Effects: - Skin irritation: mild redness or itching at the application site. - Dryness: flaking or scaling of treated skin. - Mild burning sensation: transient warmth during application. - Peeling: superficial desquamation of the epidermis. - Erythema: temporary redness of the skin.

Serious or Rare Side Effects: - Allergic contact dermatitis: intense itching, swelling, or vesicle formation. - Systemic toxicity: rare salicylate poisoning presenting with tinnitus, nausea, or metabolic acidosis when large surface areas are treated. - Severe ulceration: deep skin breakdown beyond the intended exfoliation zone. - Hyperpigmentation: persistent darkening of treated areas, especially in darker skin types.

When using Opsor, consider the following safety measures: - Avoid extensive application: limit use to ≤10% of body surface area per session. - Pre‑existing skin conditions: do not apply on open wounds, eczema, or infected lesions. - Sun exposure: use sunscreen and limit UV exposure after treatment. - Pregnancy and lactation: consult a healthcare professional before use. - Pediatric use: avoid in children under 12 years unless directed by a physician. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Salicylic acid can interact with other topical agents and systemic medications.

Major Interactions (Avoid): - Concurrent use with other keratolytic agents (e.g., urea, glycolic acid) may cause excessive irritation. - Combination with topical retinoids can increase skin sensitivity and peeling.

Moderate Interactions (Monitor Closely): - Systemic salicylates (e.g., aspirin) may increase risk of salicylate toxicity if large skin areas are treated. - Use with photosensitizing drugs (e.g., tetracyclines) may heighten sunburn risk. - Co‑application with occlusive dressings can enhance absorption and irritation.
