The Effects of Tegaserod, a Gastrokinetic Agent, on Voltage-Gated K⁺ Channels in Rabbit Coronary Arterial Smooth Muscle Cells

The field of [smooth muscle physiology] is constantly unraveling the complex mechanisms governing the function of these vital tissues. This research investigates the effects of tegaserod, a gastroprokinetic agent used to treat irritable bowel syndrome, on voltage-gated K+ channels in rabbit coronary arterial smooth muscle cells. The researchers used the whole-cell patch-clamp technique to assess the impact of tegaserod on Kv channel activity.

Their findings demonstrate that tegaserod inhibits Kv channels in a concentration-dependent and use (state)-dependent manner, suggesting that it may have potential implications for vascular function. The study also identified the Kv1.5 subtype as the major Kv channel target of tegaserod. The researchers highlight the importance of further investigation into the potential cardiovascular effects of tegaserod.
