Results. Baseline demographics, lifestyle, constipation, number of prolapses, grade of hemorrhoid severity, and duration of experiencing hemorrhoidswerecomparableinbothgroupsofpatients.eeffectsofCQ-APandthecommercializedrectalsuppositoryonbleeding, prolapse size, and anal pain were comparable. e patients in both groups were satisfied with both products at comparable levels and stated a preference for further use in the case of hemorrhoids recurrence. In terms of safety, the patients in the commercialized rectal suppository group experienced a higher incidence of adverse events, including anal pain and bleeding. Conclusion. Rectal suppositories containing a combined extract of CQ and AP show potential in alleviating hemorrhoidal symptoms with a good safety profile. 1.
