Description:
Aldara was launched in the US for the topical treatment of genital warts caused by human papillomavirus (HPV). It can be prepared in a six step approach beginning with the nucleophilic substitution of 4-chloro-3-nitroquinolone with isobutylamine or via a thermal electrocyclic ring closure of 1 - and 2-azahexatriene systems. Aldara has antiviral and antitumor properties, with the former activity arising from the induction of cytokines, in particular, INF-α. Aldara also induces TNF-γ, IL-1α, IL-1β, IL-1ra, IL-6, IL-8, IL-10, GM-CSF, G-CSF and MID-la formation 1-4 hr after stimuli. The exact cells responsible for the response have not been determined, however, it is not activating T lymphocytes, NK cells, B lymphocytes, or dendritic stem cells but monocytes (CD14+, CD36+, HLA-DR+, HLA-DQ±, CD19-, CD16- and CD23-) are partly responsible. The speculation is that Aldara may interact with a kinase modulating the transduction pathway leading to cytokine genes. There is no direct antiviral activity (induction of IFN does not follow true dose response) and it is not mutagenic. The hydroxylated metabolite also induces IFN-α.
It can be used for the treatment of adult external genital and perianal genital warts at 3 times per week. Just before sleep, first apply the product evenly in a thin layer on the surface of the wart and gently massage until the product is completely absorbed. The position of the medication should not be packeted and should be maintained for 6 to 10 hours, and then wash with a neutral soap and clean water for clearing the drugs in the administration site. Wash your hands before and after treatment. 250 mg of cream can be applied to 20cm2 of wart. Avoid excessive application of the drug. Patients should continue the treatment until the wart is completely cleared. Wart can be cleared within 2-4 week at the fastest speed and can be generally cleared within 8 to 12 weeks. The medication should be not more than 16 weeks. After the treatment, patients with mild erythema locally who does not have to be discontinued for drug; if the patients feel general malaise or get local skin reactions (edema, erosion, pain, etc.), the drug should be discontinued. Only when the reaction is alleviated can they continue the medication.
