PBG (1-Phenylbiguanide HCl), as 5-HT3 receptor agonists(3–100 μM, pEC50 5.05±0.06), acutely increased XII (hypoglossal) burst frequency and regularity, and decreased bursts/episode . Phenylbiguanide produced a dose-related (10-500 microM) increase in the release of dopamine (280-2000%). When nomifensine (5 microM) was included in the Ringer solution, the effect of PBG on the release of dopamine was ameliorated or inhibited. Phenylbiguanide, infused intravenously for 15 min, elicited a sustained reflex decrease of renal sympathetic nerve activity (RSNA) but only transient (<3 min) changes of arterial blood pressure (BP) and heart rate (HR) in methohexital-anaesthesized rats.
