Ativan (Lorazepam) Does Not Help with Anal Fissures
Ativan (lorazepam) is not recommended for the treatment of anal fissures as there is no evidence supporting its use for this condition. 1, 2 Instead, evidence-based treatments focus on reducing internal anal sphincter hypertonia through other mechanisms.
Pathophysiology and First-Line Treatment
Anal fissures are caused by:
- Mechanical trauma from hard stool passage (though less than 25% of patients report constipation)
- Internal anal sphincter hypertonia leading to decreased anodermal blood flow 1
First-Line Management (Non-Operative):
Dietary and lifestyle modifications:
Topical treatments to reduce pain:
Evidence-Based Pharmacological Options
For acute anal fissures that don't respond to conservative measures, the following medications are recommended:
Topical Calcium Channel Blockers:
- 2% Diltiazem or 0.3% Nifedipine - These reduce internal anal sphincter tone and increase local blood flow
- Healing rates range from 65-95% 1, 2
- Nifedipine shows higher remission rates (77.4%) compared to diltiazem (54%) and provides earlier pain relief 3
- Both have fewer side effects than nitrates 2
Topical Nitrates:
- Glyceryl trinitrate (nitroglycerin) ointment
- Acts as a vasodilator to increase blood flow and reduce sphincter tone
- Less effective than calcium channel blockers and associated with more headaches and hypotension 1
Other Options:
- Botulinum toxin injection for refractory cases (75-95% cure rate)
- Can be considered if no improvement after 4-6 weeks of conservative treatment 2
Important Considerations
Duration of therapy:
Adjunctive treatments:
Avoid manual dilatation:
When to consider surgery:
Common Pitfalls
- Misdiagnosing hemorrhoids as the cause of anorectal symptoms
- Failing to recognize atypical presentations
- Inadequate trial of conservative treatment
- Premature progression to invasive treatments
- Not addressing dietary and lifestyle factors
- Discontinuing treatments prematurely 2
Remember that approximately 50% of patients with acute anal fissures will heal with conservative measures within 10-14 days 1. However, many patients (59% in one study) may require additional treatment over a longer follow-up period 4.
