ALDARA vs ZYCLARA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imiquimod is a toll-like receptor 7 (TLR7) agonist that activates immune cells, leading to the production of cytokines such as interferon-alpha, which promotes antiviral and antitumor activity.
Imiquimod acts as an immune response modifier. It activates toll-like receptor 7 (TLR7), leading to the production of cytokines such as interferon-alpha, interleukin-12, and tumor necrosis factor-alpha, which stimulate both innate and adaptive immune responses.
Apply a thin layer to the target lesion(s) 3 times per week (e.g., Monday, Wednesday, Friday) for up to 16 weeks. Do not occlude. Wash hands before and after application.
