Is this trial a fit for you?

Likely a good fit

Adults 18–75 with a clinical or anoscopic diagnosis of acute hemorrhoidal disease (Goligher grade II–IV) who started topical nifedipine 0.3% plus lidocaine 1.5% within the past 5 days and can give informed consent are eligible.

Probably not a fit

Patients with complicated hemorrhoids (thrombosis or strangulation), coagulopathies, active cancer, on anticoagulants/chemotherapy, severe cardiovascular instability, pregnancy/breastfeeding, or known allergy to lidocaine are unlikely to benefit or are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, observational, single-center study of patients who are already receiving topical nifedipine 0.3% plus lidocaine 1.5% as part of routine care. Participants will apply the ointment twice daily for at least 21 days and complete four assessments over about 30 days (baseline, day 10 phone call, day 21 in-person visit, day 30 phone call). The primary outcome is change in the Hemorrhoidal Disease Symptom Score (HDSS), with secondary measures including changes in prolapse grade, quality of life, and prevention of thrombosis. Data will be entered into a web-based electronic database by study staff at the Cardarelli Hospital center in Naples, Italy.

Why it matters

Potential benefit: If effective, the topical combination could speed symptom relief, reduce prolapse severity, and lower the need for invasive procedures.

How similar studies have gone: Topical calcium-channel blockers like nifedipine have shown benefit in anal fissures, but evidence specifically for nifedipine plus lidocaine in hemorrhoidal disease is limited and largely based on small or real-world studies.
