Buflomedil poisoning: five cases with cardiotoxicity

Toward a broader view of mechanisms of drug cardiotoxicity

Cardiotoxicity, defined as toxicity that affects the heart, is one of the most common adverse drug effects. Numerous drugs have been shown to have the potential to induce lethal arrhythmias by affecting cardiac electrophysiology, which is the focus of current preclinical testing. However, a substantial number of drugs can also affect cardiac function beyond electrophysiology. Within this broader sense of cardiotoxicity, this review discusses the key drug-protein interactions known to be involved in cardiotoxic drug response. We cover adverse effects of anticancer, central nervous system, genitourinary system, gastrointestinal, antihistaminic, anti-inflammatory, and anti-infective agents, illustrating that many share mechanisms of cardiotoxicity, including contractility, mitochondrial function, and cellular signaling.

The use of buflomedil in reduction mammaplasty for a previously irradiated breast: a case report

In recent years, lumpectomy combined with breast irradiation and chemotherapy, as a part of conservation therapy for breast cancer, has well-established results. Little has been published on reduction mammoplasty for breast-irradiated patients. These patients have increased risks of nipple necrosis, wound complications, and delayed healing. Breast reduction techniques that rely on minimum skin undermining combined with the use of buflomedil may prevent major postoperative complications in breast-irradiated patients. Buflomedil was administered intraoperatively and for 14 days after the procedure. The use of buflomedil in reduction mammaplasty for a previously irradiated breast patient has not been heretofore described. The case of a 58-year-old woman who underwent bilateral breast reduction after breast conservation therapy is reported.

Rapid HPLC measurement of buflomedil in plasma in poisoning cases

A rapid high-performance liquid chromatographic method for the determination of buflomedil in human plasma is described. It requires a single liquid-liquid extraction step from 1 mL of plasma with diethyl ether followed by chromatography on a Nova Pak C(18) reversed-phase column and detection by ultaviolet light. Metoclopramide was used as internal standard. The method is sensitive with a quantification limit at 500 ng/mL. It was used for the determination of buflomedil in biological fluids in poisoning cases.
