The first compound studied was glycine which was hypothesized by Daniel Javitt after observation that people with phencyclidine(PCP)-induced psychosis were lacking in glutamate transmission. [1] (PCP is an NMDA receptor antagonist that blocks glutamate.) In giving glycine to people with PCP-induced psychosis a recovery rate was noted.
A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations.In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy.
Dose response relationship of cell killing by chemotherapeutic drugs on normal and cancer cells. At high doses the percentage of normal and cancer cells killed is very similar. For this reason, doses are chosen where anti-tumour activity exceeds normal cell death. [4]
The approval allows the therapy to be used in a reduced dosing of 1.5 milligrams per kilogram every two weeks, in patients who have achieved and maintained a complete response or better for a ...

High-dose chemotherapy and bone marrow transplant (HDC/BMT), also high-dose chemotherapy with autologous bone marrow transplant (HDC/ABMT or just ABMT), was an ineffective treatment regimen for metastatic breast cancer, and later high-risk breast cancer, that was considered promising during the 1980s and 1990s.
