Abstract: | The influence of cigarette smoke on nicorandil plasma levels at a dose of 10 mg/kg administered orally was investigated in rats. The animals were exposed to standard and nicotine-less cigarette smoke for 8 min using a 'smoking machine'. In nonsmoking control rats, nicorandil plasma levels increased rapidly and reached the maximum (approx. 7.6 micrograms/ml) after 1 h and then decreased gradually. On the other hand, nicorandil plasma levels in the rats inhaling standard cigarette and nicotine-less cigarette smoke reached the maximum (approx. 4.7 and 4.9 micrograms/ml, respectively) after 1-2 h. These results suggest that nicorandil plasma levels after oral administration are influenced not only by standard cigarette smoke but also by nicotine-less cigarette smoke. |
