Винорелбин

Описание

Vinorelbine is a semisynthetic vinca alkaloid differing from vinblastine in the catharantine moiety of the molecule. It is claimed to have a broad spectrum of action both in vifro and in vivo; clinically it has been found effective in the treatment of non-small cell lung cancer, advanced breast cancer, ovarian cancer and Hodgkins disease.

Использование

Vinorelbine base is an antineoplastic agent with anti-mitotic properties.

Определение

ChEBI: A vinca alkaloid with a norvinblastine skeleton.

Фармакокине?тика

This semisynthetic alkaloid is unique in having oral bioavailability, but it currently is available only for IV injection. The initial phase elimination half-life is on par with that observed for vincristine and vinblastine, and the terminal phase half-life is between 28 and 44 hours.

Клиническое использование

Vinorelbine is particularly useful in the treatment of advanced non–small cell lung cancer and can be administered alone or in combination with cisplatin. It is thought to interfere with mitosis in dividing cells through a relatively specific action on mitotic microtubules.

Побочные эффекты

Although dose-limiting granulocytopenia is the major adverse effect, potentially fatal interstitial pulmonary changes have been noted, and patients with symptoms of respiratory distress should be promptly evaluated. As with all vinca alkaloids, elimination is primarily hepatobiliary, and dosage reduction should be considered in patients with liver dysfunction.
