Benjakul Extract and Loratadine for Treatment Allergic Rhinitis Patients

Study Overview
=================
Brief Summary
-----------------
To compare the effectiveness of Benjakul extract capsules at 300 mg per day with Loratadine drug in the treatment of allergic rhinitis patients in small group (Clinical Trial Phase II). To study the safety and side effects of Benjakul extract capsules 300 mg per day and Loratadine drug for allergic rhinitis patients.

Detailed Description
-----------------
Group 1consists of 30 patients, taking Benjakul dosage 100 mg or 1 capsule 3 times daily. beforeBreakfast, lunch and dinner. Group 2 consists of 30 patients, taking Loratadine dosage 100 mg 1time daily.Taking drug is as follows Volunteers will be treated by drugs continuously for a period of six weeks. Taking three times a day 1 tablet before meals (breakfast, lunch, dinner), giving drug based on random. Volunteers groups receiving Benjakul take 1capsule 3 times daily. Volunteer groups receiving Loratadine take loratadine tablet first 1capsule 1 time daily and then taking placebo once 1 capsule during the day and 1 capsule in the evening. Patients have to report all the 42 days (6 weeks). The blood and urine samples will be collected and evaluated before the treatment and later following symptoms after 21 and 42 days (3 weeks and 6). Assessment methods to measure the nasal, other of nasal symptoms, assessment of quality of life and overall treatment (Global assessment),Acoustic Rhinometry and tools which are used to evaluate nasal congestion. measuring the narrowest cross-sectional area of the nasal cavity, this tool takes a short time to evaluate and can determine volume of nasal cavity by calculating of the CSA in the nasal cavity. In addition, the researchers areable to check the safety of using medications by taking blood and urine samples to check Hematology CBC, Lipid profile, FBS monitoring of renal function (Renal function test) and liver function tests (Liver Function Tests: LFTs). So, the volunteers must NPO before every blood drawing.
