Journal of Oral Pathology
|January 1, 1978
Summary
Levamisole significantly improved recurrent aphthous stomatitis compared to placebo. Most patients experienced clinical improvement after treatment with levamisole, demonstrating its efficacy for this oral condition.
Area of Science:
- Immunology
- Dermatology
- Oral Medicine
Background:
- Recurrent aphthous stomatitis (RAS) is a common, painful oral condition.
- Current treatments for RAS have variable efficacy and potential side effects.
Purpose of the Study:
- To evaluate the efficacy of levamisole in treating recurrent aphthous stomatitis.
- To compare levamisole treatment with placebo in a double-blind study.
Main Methods:
- A double-blind, placebo-controlled study was conducted with 65 patients diagnosed with RAS.
- Patients were randomized to receive either levamisole or placebo.
- Treatment outcomes were assessed, and a crossover design was implemented for non-responders and placebo recipients.
Main Results:
- Nineteen out of 34 patients (55.9%) showed improvement with levamisole, compared to only five out of 31 patients (16.1%) with placebo (P < 0.004).
- Following a code break and treatment adjustments, 46 out of 60 patients (76.7%) reported clinical improvement.
Conclusions:
- Levamisole demonstrates significant efficacy in treating recurrent aphthous stomatitis.
- The drug appears to be a promising therapeutic option for patients suffering from RAS.
