Sucralfate induces proliferation of dermal fibroblasts and keratinocytes in culture and granulation tissue formation in full-thickness skin wounds

Sucralfate is used to induce healing of gastrointestinal tract ulcers. We evaluated its potential utility in the healing of skin wounds. Initial experiments examined the effects of the sucralfate on proliferation of cultured dermal fibroblasts and keratinocytes. Sucralfate induced proliferation in quiescent cultures of both cell types. Additionally, sucralfate enhanced prostaglandin E₂ synthesis in basal keratinocytes and in interleukin-1-stimulated keratinocytes and dermal fibroblasts. Basal interleukin-1 and 6 release were not affected by sucralfate, but the agent enhanced interleukin-1-stimulated interleukin-6 release from fibroblasts. When applied daily to full-thickness wounds in rats, sucralfate increased the thickness of granulation tissue when assessed at day 12.
