Pharmacological action
Pharmacodynamics
Antitumor agent. It is an inhibitor of mitosis. Paclitaxel specifically binds to microtubule beta-tubulin, disrupting the depolymerization of this key protein, which leads to the suppression of normal dynamic reorganization of the microtubule network, which plays a decisive role during interphase and without which the implementation of cellular functions in the mitosis phase is impossible. In addition, paclitaxel causes the formation of abnormal microtubule bundles throughout the cell cycle and the formation of several centrioles during mitosis.
Pharmacokinetics
Plasma Protein Binding 89-98%. Biotransformed mainly in the liver. It is excreted both by the kidneys in an unchanged form, and with bile (both unchanged and in the form of metabolites).
Indications
Ovarian cancer (including with ineffective platinum drugs)
breast cancer
lung cancer

From the cardiovascular system: arterial hypotension, bradycardia, conduction disorders, peripheral edema.
Other: arthralgia, myalgia, peripheral neuropathy.
Local reactions: thrombophlebitis, with extravasation – necrosis.
Drug Interaction
In laboratory studies in patients receiving sequential infusions of paclitaxel and cisplatin, a more pronounced myelotoxic effect was observed when paclitaxel was administered after cisplatin with an average of 20% paclitaxel clearance.
Cimetidine’s previous intake did not affect the mean clearance of paclitaxel overall.
Based on in vivo and in vitro data, it can be assumed that patients receiving ketoconazole, Paclitaxel metabolism is inhibited.
