Etosid 100mg (Etoposide)

DESCRIPTION

Etosid 100mg consist of semisynthetic derivative of the mandrake plant substance podophyllotoxin, persuaded DNA strand breaks by preventing the activity of topoisomerase II and generating free radicals.
Etosid 100mg Injection is taken by mouth or Injection into a vein.
Etosid 100mg Injection which used as prescription drug provided under guidance of medical practioners.

INDICATION

Etosid 100mg Injection used in concomitant use with other cancer medication in the treatment of refractory testicular tumors and as first line treatment in patients with small cell lung cancer.

MECHANISM OF ACTION

Etoposide has been revealed to cause metaphase capture in chick fibroblasts. Its major effect, however, occurs to be at the G2 portion of the cell cycle in mammalian cells. Two variety dose-dependent reaction are observed. At high concentrations (10 mcg/mL or more), lysis of cells penetrate mitosis is observed. At low concentrations (0.3 to 10 mcg/mL), cells are prohibiting from entering prophase. It does not prevent microtubular assembly. The potent macromolecular effect of Etoposide results to be the DNA strand induction breaks by a combination with DNA topoisomerase II or the production of free radicals.
