5) Able to communicate effectively with study personnel. 6) Willing to provide written informed consent to participate in the study. 7) All volunteers must be judged by the principal or sub-investigator or physician as normal and healthy during a pre-study safety assessment performed within 28 days of the first dose of study medication which will include:

1. A physical examination (clinical examination) with no clinically significant finding.
2. Results within normal limits or clinically non-significant for the following tests: Hematology Hemoglobin Total RBC count Total WBC count Platelet count

   Differential leukocyte count:

   Neutrophils Lymphocytes Eosinophils Monocytes Basophils Blood indices: HCT Biochemistry BUN, Serum creatinine, Random glucose, SGPT \& SGOT Alkaline phosphatase Uric acid Serum bilirubin Serum total protein: Total proteins, Albumin Serum electrolytes: Serum sodium, serum chloride, serum potassium, serum phosphorous, serum calcium Urinalysis Color, quantity, specific gravity, odour, appearance, reaction, albumin, bilirubin, ketone bodies, sugar, urobilinogen and microscopical examination (performed based on clinical judgment) Immunological Tests HIV-I \& II, HbsAg ,Anti HCV
   * Additional tests and/or examinations (apart from mentioned in protocol) may be performed, if necessary, based on principal investigator discretion.
   * All results will be assessed against the current laboratory normal ranges at the time of testing and a copy of the normal ranges used will be included in the study documentation.
