Study aimed to evaluate the efficacy and tolerance of Lazolex®, an emollient gel, to treat mucocutaneous lesions caused by herpes simplex virus.
A single-center, single-arm, open-label, phase II clinical trial was conducted with 30 patients divided into two groups: 15 patients with herpes simplex virus type 1 (HSV-1) infections and 15 with herpes simplex virus type 2 (HSV-2) infections. All received topical treatment with Lazolex® Gel four times daily for 10 days. The efficacy and tolerance of the treatment were evaluated on day 10 and day 20 after the study started. In addition, recurrence rates were evaluated before treatment with Lazolex® and after a 4-year follow-up period after treatment.

Tolerance outcomes were evaluated using both objective and subjective criteria. The objective criteria included the comparison of laboratory tests and physical examinations before and after Lazolex® Gel treatment. The subjective criteria included complaints and symptoms reported by patients. In the event of adverse reactions, they were assessed by attending physicians. Individual tolerance was categorized as follows:
Very satisfactory: No clinically significant changes in physical examination or laboratory tests, and no adverse reactions.
Satisfactory: Insignificant changes in physical examination or laboratory tests, or mild adverse reactions that do not require a change in treatment.
Unsatisfactory: Significant changes in physical examination or laboratory tests and/or the occurrence of adverse reactions that require the withdrawal of the product, as well as prescribing treatment to address the adverse reaction
