In Vitro Milrinone (1 µM) increases PKA activity in hypoxic myocytes to normoxic levels. Milrinone (50 nM) normalizes TP receptor sensitivity in hypoxic myocytes by restoring PKA-mediated regulatory TP receptor phosphorylation[1]. Milrinone significantly reduces NE-induced vasoconstriction, attenuating both NE sensitivity and maximal tension generation. Inhibition of ATP-sensitive K+ channels or voltage-gated K+ channels do not prevent the milrinone-induced attenuation of NE responses[4].
In Vivo Milrinone (1 μg/kg/min, i.v.) significantly reduces PAP, PVR (−18.96 ± 1.7%), and LAP (−26.03 ± 2.3%) in congestive heart failure (CHF) rats. Milrinone (1 mg/mL, inhalation) results in a near-maximal reduction of PAP without significant effects on AP, decreases pulmonary artery pressure similarly in a larger collective of CHF rats. Milrinone inhalation selectively increases cAMP but not cGMP plasma concentrations in both groups. Repeated milrinone inhalations even reduce lung wet/dry weight ratio[2]. Milrinone (49.5 μg) largely shifts the ESPVR upwards and significantly increases end-systolic pressure (ESP(0.08)) and the systolic pressure-volume area (PVA(0.08)) at a mid-range LV volume (0.08 mL/g myocardium). Milrinone also slightly decreases LV ESP(ESV) and decreased Ea[3].
Animal Admin In juvenile rats of 100 ± 8 g body weight (bw), CHF is induced by supracoronary aortic banding. In brief, rats are anesthetized by intraperitoneal injection of ketamine (87 mg/kg bw) and xylazine (13 mg/kg bw). Rats are placed in the supine position, the chest wall is shaved, and a left thoracotomy is performed in the third intercostal space during ventilation with 100% O2. The ascending aorta is freed from connective tissue and partially occluded by implantation of a titanium clip with a defined internal diameter of 0.8 mm. After surgical closure of the thorax, the rats are allowed to recover from anesthesia. For postoperative analgesia, rats receive 250 mg/kg bw of metamizole intramuscularly immediately after the operation and on the first postoperative day. Sham-operated rats serve as controls. After recovery from anesthesia, the animals are placed in cages with free access to water and standard laboratory diet. For inhalation, milrinone (0.2-5 mg/mL) or NaCl (0.9%) are nebulized using an ultrasonic nebulizer and inhaled for 3 min at identical peak inspiratory pressures as used throughout the experiment. A 3-min nebulization of 1 mg/mL milrinone results in vaporization of 14 μg of the phosphodiesterase-3 inhibitor as determined by microgravimetry. Therefore, the respective dose of 39 μg/kg is analog to inhaled doses in human studies. For intravenous delivery, milrinone (initial bolus of 2-10 μg/kg, followed by 0.2-1 μg/kg/min) or equivalent volumes of NaCl (0.9%; initial bolus of 1.6 mL/kg, followed by 10 μL/kg/h) are administered by an infusion pump for 10 min.
