Sucralfate forms a polyanion gel that coats and protects damaged mucosal/skin tissue. It stimulates mucus production and enhances tissue growth factors (including epidermal growth factor), actively promoting epithelial healing of fissures and ulcerated tissue.
-
Lidocaine blocks sodium channels in peripheral nerve endings, preventing pain signal transmission. It provides rapid numbing of the intensely sensitive anal region, reducing pain during and after bowel movements.

Metronidazole has antibacterial action against anaerobic organisms common in the perianal region. It also has a direct anti-inflammatory effect that helps reduce swelling in hemorrhoidal tissue.
No major drug interactions are established for this topical combination at standard doses, given minimal systemic absorption. However, always inform your doctor of all medications being used.
A
2024 RCT from AIIMS Raipur found that the combination of
sucralfate + metronidazole ointment is as effective as diltiazem ointment for treating acute fissure-in-ano, with benefits in both ulcer healing and pain control. A
2023 pilot study (PMC) also demonstrated promising healing results with 3% sucralfate ointment alone in chronic anal fissures, supporting the rationale for sucralfate-based formulations.
Note: Sucral Ano is a prescription medication. Use only under medical guidance and complete the full prescribed course to prevent recurrence.
