In the experimental solutions, varying concentrations from 1 nmol/L to 1 μmol/L of each drug were added to fresh control Tyrode’s solution.

In some of the experiments, the control solution also contained comparable quantities of the stock vehicle, 0.01% ethyl alcohol and 0.01% acetic acid.

Similar to astemizole, the block of I) in a guinea pig ventricular myocyte.

Terfenadine and astemizole are widely prescribed nonsedating antihistamines that have been associated with QT-interval prolongation and ventricular arrhythmias.

Since potassium channels are intrinsically involved in repolarization, this study was designed to evaluate the effect of the nonsedating antihistamines on potassium channel modulation. The dialyzing pipette solution was buffered with EGTA, and ionic channels other than potassium were pharmacologically inhibited or electrically inactivated.

Statistical analysis also included the two-tailed Student’s test for paired samples.

A two-factor ANOVA using % block as the outcome variable was performed to determine whether the drug effects were channel specific and whether the antihistamines differed in their K currents were recorded in response to hyperpolarizing pulses negative to −80 m V in both rat and guinea pig ventricular myocytes.

The current/voltage (I/V) relation in control (Ctl) solutions is compared with that obtained in 1 μmol/L of either AST or TERF.

Little or no significant effect is evident at the voltage ranges examined.Antihistamines are a group of structurally diverse compounds frequently prescribed for treatment of allergies, urticarial diseases, and symptoms associated with upper respiratory infections.The medications act via specific blockade of the H Recently, there have been several reports of adverse cardiac effects in patients taking this group of drugs.The mean percent inhibition (% block) and amount of recovery of the current on drug washout (% recovery) was tabulated.Each cell served as its own control, with data acquisition before, during, and after drug application.Graph illustrates the voltage-dependent inhibition of I) in a guinea pig ventricular myocyte.
