Brief Summary:

This is an open label randomised, 2-way crossover, comparative bioequivalence study.

Condition or disease	Intervention/treatment	Phase
Healthy	Drug: Desloratadine and pseudoephedrine	Phase 1

Detailed Description:

The objective of this study was to compare the rate and extent of absorption of Dr. Reddy's Laboratories Ltd., India, desloratadine-pseudoephedrine and Schering Corporation, U.S.A.(Clarinex-D® 24-HOUR), desloratadine-pseudoephedrine, administered as a 1 x 5 mg/240 mg extended-release tablet under fasting conditions. The treatment phases were separated by a washout period of 14 days. 34 subjects(19 males and 15 females) were dosed and were enrolled in the study; 31 of these enrolled subjects completed the study.

Exclusion Criteria:

• Clinically significant illness or surgery within 4 weeks prior to dosing.
• Any clinically significant abnormality or abnormal laboratory test results found during medical screening.
• Any reason which, in the opinion of the Medical Sub-Investigator, would prevent the subject from participating in the study.
• Positive test for hepatitis B, hepatitis C, or HIV at screening.
• ECG abnormalities (clinically significant) or vital sign abnormalities (systolic blood pressure lower than 90 or over 140 mmHg, diastolic blood pressure lower than 50 or over 90 mmHg, or heart rate less than 50 or over 100 bpm) at screening.
• History of significant alcohol abuse or drug abuse within one year prior to the screening visit.

• History of allergic reactions to desloratadine, pseudoephedrine or other related drugs.
• Use of any drugs known to induce or inhibit hepatic drug metabolism (examples of inducers: barbiturates, carbamazepine, phenytoin, glucocorticoids, omeprazole; examples of inhibitors: antidepressants (SSRI), cimetidine, diltiazem, macrolides, imidazoles, neuroleptics, verapamil, fluoroquinolones, antihistamines) within 30 days prior to administration of the study medication.
• Use of an investigational drug or participation in an investigational study within 30 days prior to dosing.
• Clinically significant history or presence of any gastrointestinal pathology (e.g. chronic diarrhea, inflammatory bowel diseases), unresolved gastrointestinal symptoms (e.g.diarrhea, vomiting), liver or kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of the drug.
• Any clinically significant history or presence of neurological, endocrinal, cardiovascular, pulmonary, hematologic, immunologic, psychiatric, or metabolic disease.
• Use of prescription medication within 14 days prior to administration of study medication or over-the-counter products (including natural food supplements, vitamins, garlic as a supplement) within 7 days prior to administration of study medication, except for topical products without systemic absorption and hormonal contraceptives.
• Difficulty to swallow study medication.
• Use of any tobacco products in the 3 months preceding drug administration.

• Any food allergy, intolerance, restriction or special diet that, in the opinion of the Medical Sub-Investigator, could contraindicate the subject's participation in this study.

  ● A depot injection or an implant of any drug (other than hormonal contraceptives) within 3 months prior to administration of study medication.

• Donation of plasma (500 mL) within 7 days prior to drug administration. Donation or loss of whole blood (excluding the volume of blood that will be drawn during the screening procedures of this study) prior to administration of the study medication as follows:
