ReviewPixantrone: a novel aza-anthracenedione in the treatment of non-Hodgkin's lymphomas.
Pixantrone (BBR-2778) is a novel mitoxantrone-like drug, which lacks the 5,8-dihyroxy substitution groups thought to be responsible for the cardiac toxicity associated with mitoxantrone. In Phase I/II single-agent pixantrone clinical trials, neutropenia was the dose-limiting toxicity and the maximum tolerated dose was 150 mg/m(2)/week for 3 weeks every 4 weeks. ⋯ In the BBR-2778, methylprednisolone, cisplatin and cytosine arabinoside (BSHAP) regimen, 58% overall response and 37% complete response were achieved. A number of randomised studies of pixantrone (BBR-2778) in patients with relapsed indolent or aggressive lymphomas are ongoing.

Neuropathic pain is a frequent condition that can result from a variety of underlying conditions and is frequently chronic and difficult to treat. A number of drugs are used to treat neuropathic pain, including anticonvulsants and antidepressants. ⋯ There is good evidence that oxcarbazepine is effective in relieving the pain associated with trigeminal neuralgia. Its efficacy in treating painful diabetic neuropathy is less clear; however, it seems to be useful when tolerated at doses of 1800 mg/day.
