Condylom podophilin. How does podophyllotoxin work and what is it used for?

Podophyllin The herbal extract known as podophyllin is a crude, non-standardised, and impure resin preparation obtained from the rhizomes of the Podophyllum plant species P peltatum, or P emodi.

The antiwart ingredients are antimitotically acting lignans, 5 of which podophyllotoxin is the most potent. Toxic ingredients often cause unpredictable and severe local toxicity including painful burns and ulcerations. Podophyllin is unstable during clinic storage, with frequent crystallisation and formation of inactive picroisomers of lignans.

The resin must condylom podophilin talpi szemölcsök áttekintése off 4—6 hours after application; use of a protective inert ointment for the surrounding skin is recommended. There is a risk of systemic intoxication, as ingredients at high concentrations may be absorbed and condylom podophilin to vital organs including the gastrointestinal mucosa, the kidneys, the bone marrow, and the CNS.

Of greatest concern are the number of case reports revealing that following podophyllin painting of large condylomas, after subdermal injection into plantar condylom podophilin, or following accidental ingestion, podophyllin may cause fatal or near fatal intoxication 9— 17 due to CNS influence, coma, respiratory depression, etc, and cardiovascular crisis.

A formal regulatory review and safety evaluation of podophyllin has never been performed, although mutagenicity, carcinogenicity, and reproductive toxicity studies indicate that podophyllin is potentially very dangerous. In mice, podophyllin seems teratogenic, inducing a high frequency of fetal mortality; in rats no teratogenic influence has been demonstrated. Such quantities are far below levels of clinical significance 10 ; cancer patients receiving daily intravenous injections of 0.

A negative influence was observed in the offspring exposed to the highest dose 2. Although reproductive toxicity studies in animals have not shown teratogenicity and the half life appears to be short and systemic elimination occurs within a few days, we still believe that podophyllotoxin should be avoided during pregnancy since the possibility cannot be excluded that the drug might accumulate in the human fetus.

As a further precaution, we also recommend that conception should be avoided during the week following completion of podophyllotoxin therapy. Conclusions Use of the crude herbal remedy podophyllin is associated with low production costs, but the cost benefit versus the risk ratio of the product is highly questionable.

Further podophyllin use is not only redundant but should be abandoned in favour of its modern pharmaceutical replacement—that is, podophyllotoxin preparations with well defined pharmacokinetic, metabolic, and toxicity safety profiles. Podophyllotoxin solution and cream have been documented as safe and effective for self therapy of anogenital warts table 2 and are recommended as first line therapy.
