RPL 554 is a known drug candidate for respiratory diseases, particularly in patients with asthma or chronic obstructive pulmonary diseases. | [in vivo]
Ensifentrine (RPL-554; 10 mg/kg; Oral administration; once) significantly inhibits eosinophil recruitment following antigen challenge in ovalbumin-sensitized guinea pigs[1].
The inhalation of dry powder containing Ensifentrine by conscious guinea pigs (25% in micronized lactose) 1.5 h before antigen exposure significantly inhibits the recruitment of eosinophils to the airways[1].
Exposure of conscious guinea pigs to inhalation of dry powder containing Ensifentrine (2.5%) in micronized lactose significantly inhibits histamine-induced plasma protein extravasation in the trachea and histamine-induced bronchoconstriction over a 5.5-h period[1]. | Animal Model: | Male Dunkin Hartley guinea pigs (200-300 g) injected with ovalbumin[1]. | | Dosage: | 10 mg/kg
| | Administration: | Oral administration; once | | Result: | Significantly inhibits eosinophil recruitment following antigen challenge in ovalbumin-sensitized guinea pigs. |
