Besta Uses, Dosage, Side Effects, Food Interaction and all others data.
Besta, a piperidine derivative, is a long-acting, nonsedating, second-generation histamine receptor antagonist that binds preferentially to peripheral H1 receptors. It is metabolised to active metabolite, carebastine. It has antihistaminic, antiallergic activity and prevents histamine-induced bronchoconstriction. It does not have significant sedative or antimuscarinic actions.

Precaution
It is advisable to exercise caution when using ebastine in patients known to have the following conditions: long QT syndrome, hypokalaemia, treatment with any medicine known to produce an increase in QT interval or inhibit CYP3A4 enzyme systems such as azole antifungals and macrolide antibiotics. Use in Pregnancy and Lactation The safety of ebastine during pregnancy and lactation has not been established. Besta should not be used during pregnancy only if clearly needed. It is not known whether ebastine is excreted in milk, therefore, ebastine should not be used during lactation.
Interaction
The interaction of ebastine in combination with either ketoconazole or erythromycin (both known to prolong the QTc interval) has been evaluated. A significant pharmacokinetic and pharmacodynamic interaction has been observed with this combination; an 18-19 msec (4.7% - 5%) increase in QTc has been reported with either combination. Besta does not interact with the kinetics of theophylline, warfarin, cimetidine, diazepam or alcohol. The sedation effect of alcohol and diazepam may be enhanced. When ebastine is administered with food, there is a 1.5 to 2.0 fold increase in the plasma levels and the AUC of the main active acid metabolite of ebastine. This increase does not alter the Tmax. The administration of ebastine with food does not cause a modification in its clinical effect.
Food Interaction
- Take with or without food. Taking ebastine with food may increase its bioavailability.
Pregnancy & Breastfeeding use
The safety of Besta during pregnancy and lactation has not been established.
