BACKGROUND The mechanisms underlying the ability of cilostazol to improve walking distance in patients with intermittent claudication (IC) are not fully understood, but may be related to its phosphodiesterase type 3 (PDE3) and adenosine uptake inhibition. In the present study the effect of cilostazol on blood flow and interstitial adenosine concentration was compared with that of the PDE3 inhib...

The use of BNP as a diagnostic and therapeutic tool in the management of heart failure is promising. Additional studies need to be done regarding the use of BNP as a diagnostic tool to clarify its intrapatient and interpatient variability, especially over time. Nesiritide is the first new intravenous agent for the treatment of acute decompensated heart failure since the introduction of milrinon...

Current therapy of persistent pulmonary hypertension of the newborn (PPHN) consists of optimal ventilation, hemodynamic support and selective vasodilatation with inhaled nitric oxide (iNO). We present herein a case of PPHN non-responsive to iNO but treated successfully with a combination of iNO and intravenous milrinone, a phosphodiesterase III inhibitor. This case suggests that the drug may be...

Phosphodiesterase (PDE) inhibitors can modulate the functions of immune cells, including T lymphocytes, due to increased intracellular levels of cyclic nucleotides. The drugs (aminophylline, milrinone and sildenafil) were administered once or five times at 24 h intervals at the following doses: 20 mg/kg, i.m., 1 mg/kg, i.m. and 1 mg/kg, p.o., respectively. Th1 and Th2 cytokine levels (IL-2, IFN...

OBJECTIVE To assess the hemodynamic and vasodilating effects of milrinone lactate (ML) in patients with dilated cardiomyopathy (DCM) and New York Heart Association (NYHA) class III and IV heart failure. METHODS Twenty patients with DCM and NYHA class III and IV heart failure were studied. The hemodynamic and vasodilating effects of ML, administered intravenously, were evaluated. The following...
