DefinitionThis section has been translated automatically.
Natural catechin derivative (polyphenol), which is contained in green tea, among other things. The medical application is as a local therapeutic agent for the therapy of condylomata acuminata in the genital and perianal area in adult immunocompetent patients. The local therapeutic agent contains a purified dry extract of green tea leaves (Camellia sinensis). The main component of the extract is epigallocatechin gallate. The extract also contains a large number of other catechins.

Note(s)This section has been translated automatically.
The approval of a 10 % ointment from green tea extract is based on two randomized double-blind placebo-controlled phase III trials (CT 1017 and CT 1018). A total of 608 immunocompetent adults with genital and perianal warts were included. Of these, 401 patients were treated with Veregen 10 % ointment, 207 patients with the drug-free ointment base until complete healing of the genital warts, but for a maximum of 16 weeks. The primary endpoint was the complete removal of all condylomas. In the verum group, complete healing occurred in 61 percent of the patients. This was the case in 44 percent of the placebo group. A reduction of warts by at least half was achieved in 76 percent of the patients in the veregen group and in 52 percent in the placebo group. Regarding recurrence rates, Veregen apparently performs better than podophyllotoxin, imiquimod or cryotherapy.
