aminoplaster

Aminoplaster is a type of adhesive wound dressing designed to deliver amino-containing compounds to the skin or shallow wound bed. The term appears in medical supply catalogs to describe patches that incorporate amino acids or related polymers within a polymer matrix, enabling sustained local release at the application site. Aminoplaster dressings typically consist of a breathable backing material, a pressure-sensitive adhesive layer containing the aminocompounds, and a protective liner for storage until use. Some formulations may include antimicrobial agents or hydration-promoting additives.

Aminoplaster dressings are used for minor cuts and abrasions, burns, postoperative incisions, and certain chronic wounds where maintaining a moist healing environment is desired. They are designed to be conformable to body contours and to be removed with minimal pain or tissue disruption, reducing dressing changes and trauma.

The proposed mechanism involves local delivery of amino acids and related molecules that participate in collagen synthesis, keratinocyte function, and tissue remodeling, along with potential antimicrobial effects from cationic amino groups. Evidence for superior healing outcomes is mixed; some studies report improved comfort and decreased dressing-change frequency, while others find no clear advantage over conventional dressings. Availability and regulatory status vary by region and brand.

Safety considerations include potential skin irritation or allergic reaction to adhesive components, as well as higher cost and variable performance in wet conditions. Aminoplaster is not indicated for heavy bleeding, deep wounds, or areas of high friction without additional protective layers. The concept aligns with broader research into active or bioactive dressings that deliver therapeutic agents to the wound bed.
