Animal experiment: |
Rats: A total of 170 male Wistar rats are randomLy allocated into 17 groups (n=10) using random number tables. Short-term (40 minutes) mechanical ventilation with high tidal volume is performed to induce lung injury, impair active Na+ transport and lung liquid clearance in the rats. Unventilated rats serves as controls. To demonstrate the effect of phenylephrine on alveolar fluid clearance, phenylephrine at different concentrations (10, 1, 0.1, 0.01, and 0.001 μM) is injected into the alveolar space of the HVT ventilated rats[5]. |

Target: adrenergic α1A receptor
Ki: 1.4 μM
L-Phenylephrine is a selective agonist of adrenergic α1A receptor, with the Ki value of 1.4 μM, while having less effect against the α1B and α1C receptor subtypes, with the Ki values of 23.9 μM and 47.8 μM, respectively [1].
In Vitro: In neonatal rat cardiomyocytes, 50 μM L-Phenylephrine treatment could protect cells from apoptosis induced by hypoxia (95% N2 and 5% CO2) and serum deprivation through α-adrenergic receptor stimulation [2]. Besides, in neural progenitor cells (NPCs), 10 μM L-Phenylephrine could increase NPCs proliferation by approximately 160% [3]. Furthermore, in cultured rat neonatal CMs (NCMs), L-Phenylephrine could increase cross-sectional area, and significantly increase IL-6 mRNA levels, while decreasing PGC1α mRNA levels [4].
In Vivo: Studies in Sprague-Dawley male rats found that, local infiltration of L-phenylephrine could induce cutaneous anesthesia in a dose dependent manner, which could be significantly inhibited by α1-adrenergic receptor antagonists [5].
Clinical trial: Based on 8 unpublished studies that included 138 patients with nasal congestion, oral administration with 25 mg L-Phenylephrine could significantly reduce maximal nasal airway resistance (NAR) compared with placebo of 27.6% (95% CI 17.5% to 37.7%) [6].
