Cardiovascular diseases are life-threatening conditions and, thus, have received a great deal of attention over the years. Several mechanisms, including hemorheology changes and inflammatory effects, are considered to be involved in the pathogenesis of these diseases. Because cardiovascular dysfunction is also known to worsen hemorheology changes and influence vital symptoms, it has become critical to formulate effective therapeutic strategies to combat the deleterious effects of cardiovascular diseases. Although a wide variety of drugs have been developed for the treatment of cardiovascular diseases, the effectiveness of any agent for therapy of a given disease cannot be indicated with certainty.
Pentoxifylline (PTXF), a phosphodiesterase inhibitor, has been investigated for close to two decades because of its primary pharmacological actions on hemorheology and other anti-inflammatory effects. Several studies have been conducted to investigate the effects and mechanisms of PTXF in ischemic injury, peripheral vascular disease and heart failure. The present article is intended to emphasize the therapeutic potentials of PTXF in different types of cardiovascular diseases, focusing on the mechanisms of its pharmacological actions.
心血管疾病是危及生命的病症,因此多年来受到了广泛关注。包括血液流变学变化和炎症效应在内的多种机制被认为与这些疾病的发病机制有关。由于心血管功能障碍也会加剧血液流变学变化并影响生命体征,因此制定有效的治疗策略以对抗心血管疾病的有害影响变得至关重要。尽管已经开发出多种用于治疗心血管疾病的药物,但任何一种药物对特定疾病治疗的有效性都不能确定。
己酮可可碱(PTXF)是一种磷酸二酯酶抑制剂,由于其对血液流变学的主要药理作用和其他抗炎作用,已经被研究了近二十年。已经进行了多项研究来探讨PTXF在缺血性损伤、外周血管疾病和心力衰竭中的作用及机制。本文旨在强调PTXF在不同类型心血管疾病中的治疗潜力,重点关注其药理作用机制。
