Effect of Levodropropizine on isolated rabbit aorta contracted with phenylephrine and its Relationship with calcium

Öz

Objective: The aim of this study was to investigate the relationship between calcium (Ca+2) channels and levodropropizine, also to compare the potency of diltiazem and levodropropizine on phenylephrine pre-contracted rabbit aortic rings. Mateial-Method: 2-3 mm width rings of thoracic aorta were removed and suspended in 25 ml organ baths containing Krebs-Henseleit solution to reach baseline tension. To investigate contraction inhibiting effect of levodropropizine, Ca+2 free Krebs solution was created with Na2EDTA and pre-contraction was induced by 10-5 mol/l phenylephrine. Levodropropizine was added in baths and incubated for 15 minutes then cumulative concentration-relaxation curves were obtained increasing the addition of Ca+2 (10-4-10-2 mol/l) by consecutively. Results: Maximum response occurred with the addition of Ca+2 was inhibited 51.09±5.56% in the presence of levodropropizine (p<0.05). Potency of levodropropizine and diltiazem were calculated 95.96±3.12% and 78.28±6.78% respectively (p<0.05). The calculated IC50 values were given as −log IC50 for levodropropizine and diltiazem were 5.095 mol/l and 4.494 mol/l respectively. Discussion: The present in vitro study, it was shown that levodropropizine which is an antitussive drug inhibited extracellular Ca+2 entry by blocking the Ca+2 channels. We think this study would lead further studies which clarify the mechanism of the drug
