Trepar Uses, Dosage, Side Effects, Food Interaction and all others data.

A compound composed of a two cyclic peptides attached to a phenoxazine that is derived from streptomyces parvullus. It binds to DNA and inhibits RNA synthesis (transcription), with chain elongation more sensitive than initiation, termination, or release. As a result of impaired mRNA production, protein synthesis also declines after dactinomycin therapy. (From AMA Drug Evaluations Annual, 1993, p2015)

Generally, the actinomycins exert an inhibitory effect on gram-positive and gram-negative bacteria and on some fungi. However, the toxic properties of the actinomycins (including dactinomycin) in relation to antibacterial activity are such as to preclude their use as antibiotics in the treatment of infectious diseases. Because the actinomycins are cytotoxic, they have an antineoplastic effect which has been demonstrated in experimental animals with various types of tumor implant. This cytotoxic action is the basis for their use in the treatment of certain types of cancer. Trepar is believed to produce its cytotoxic effects by binding DNA and inhibiting RNA synthesis.

Uses

Trepar is an actinomycin used to treat a wide variety of cancers.

For the treatment of Wilms' tumor, childhood rhabdomyosarcoma, Ewing's sarcoma and metastatic, nonseminomatous testicular cancer as part of a combination chemotherapy and/or multi-modality treatment regimen

Trepar is also used to associated treatment for these conditions: Ewing's Sarcoma, Gestational Trophoblastic Disease, Ovarian Cancer, Rhabdomyosarcomas, Sarcoma, Osteogenic, Wilms' tumor, Metastatic nonseminomatous Testicular cancer

How Trepar works

Good evidence exists that this drug bind strongly, but reversibly, to DNA, interfering with synthesis of RNA (prevention of RNA polymerase elongation) and, consequently, with protein synthesis.
