Bioequivalence Study of Loratadine / Pseudoephedrine Sulfate 10/ 240 mg Extended-Release Tablets Under Fed Conditions

Study Overview
=================
Brief Summary
-----------------
The objective of this study was to compare the single-dose relative bioavailability of Ranbaxy and Schering (Claritin-D® 24 hour) 10 mg Loratadine/240 mg Pseudoephedrine Sulfate Extended-Release Tablets, in a fully replicated design, under fed conditions.

Detailed Description
-----------------
The study was conducted as an open-label, randomized, Single-Dose, Fully replicated, 4-way Crossover Study to compare the single-dose relative bioavailability of Ranbaxy and Schering (Claritin_D® 24 hour) 10 mg Loratadine/240 mg Pseudoephedrine Sulfate Extended-Release Tablets, in Healthy adult Volunteers Under Fed Conditions In each period, subjects were housed from the evenings before the dosing until after the 36 hour blood draw and were to return for subsequent blood draws at 48, 72, 96 and 120 hours post dose. Single oral 10 mg Loratadine/ 240 mg Pseudoephedrine Sulfate doses were separated by a washout period of 21 days. A total of 40 subjects and 1 alternate (34 males and 7 females) were included in this study, of which 37 (32 males and 5 females) finished the study according to the protocol.
