  • Fenspiride, an orally active non-steroidal antiinflammatory agent, is an antagonist of H1-histamine receptor. Fenspiride inhibites phosphodiesterase 3 (PDE3), phosphodiesterase 4 (PDE4) and phosphodiesterase 5 (PDE5) activities with -log IC50 values of 3.44, 4.16 and approximately 3.8, respectively. Fenspiride can be used for the research of respiratory diseases[1][2][3].

In Vitro Fenspiride (around 100 μM) inhibits histamine-induced contraction of isolated guinea pig trachea[2]. Fenspiride (≤1000 μM) produces less than 25% inhibition of phosphodiesterase 1 and phosphodiesterase 2 activities[2].
In Vivo Fenspiride (60 mg/kg; p.o. for 3 days) reduces the lipopolysaccharide-induced early rise of tumor necrosis factor concentrations in serum and in the bronchoalveolar lavage fluid (BALF) of the model of endotoxemia[3]. Fenspiride (60 mg/kg; p.o. for 3 days) reduces the lipopolysaccharide-induced primed stimulation of alveolar macrophages[3]. Fenspiride (60 mg/kg; p.o. for 3 days) reduces the increased serum concentrations of extracellular type II phospholipase A 2, the intensity of the neutrophilic alveolar invasion and the lethality due to the lipopolysaccharide[3]. Animal Model: Lipopolysaccharide-treated Male Dunkin-Hartley guinea-pigs weighing 400-600 g[3] Dosage: 60 mg/kg Administration: orally for 3 days; pretreated Result: Reduced the lipopolysaccharide-induced early rise of tumor necrosis factor concentrations in serum (4.2 vs. 2.3 ng/ml) and in the BALF (55.7 vs. 19.7 ng/ml). Reduced the lipopolysaccharide-induced primed stimulation of alveolar macrophages, (1551.5 vs 771.5 pg/μg protein, P<0.05 for thromboxane B2 and 12.6 vs. 3.6 pg/μg protein, P<0.05 for leukotriene C4). Reduced the increased serum concentrations of extracellular type II phospholipase A 2 (3.9 vs. 1.2 nmol/ml per min), the intensity of the neutrophilic alveolar invasion and the lethality due to the lipopolysaccharide.
