Primary Outcome Measures :
  1. Peak plasma concentration (Cmax) of tenofovir [ Time Frame: 0-84 hours in test and 0-72 hours in reference arm ]
    Cmax of Tenofovir will be compared between test and reference arms.

  2. Area under the plasma concentration versus time curve (AUC) of tenofovir [ Time Frame: 0-84 hours in test and 0-72 hours in reference arm ]
    AUC of tenofovir will be compared between test and reference arms.


Secondary Outcome Measures :
  1. Volume of distribution of tenofovir [ Time Frame: 0-84 hours in test and 0-72 hours in reference arm ]
  2. Time of peak plasma concentration(Tmax) of tenofovir [ Time Frame: 0-84 hours in test and 0-72 hours in reference arm ]
  3. Plasma half-life of tenofovir [ Time Frame: 0-84 hours in test and 0-72 hours in reference arm ]
  4. Renal clearance of tenofovir [ Time Frame: 0-24 hours ]
  5. Amount of tenofovir excreted in urine [ Time Frame: 0-24 hours ]
  6. Peak plasma concentration of PAS [ Time Frame: 0-12 hours ]
  7. Area under the plasma concentration versus time curve (AUC) of PAS [ Time Frame: 0-12 hours ]
  8. Renal clearance of PAS [ Time Frame: 0-12 hours ]
  9. Volume of distribution of PAS [ Time Frame: 0-12 hours ]
  10. Time of peak plasma concentration of PAS [ Time Frame: 0-12 hours ]
  11. Plasma half-life of PAS [ Time Frame: 0-12 hours ]
  12. Amount of PAS excreted in urine [ Time Frame: 0-12 hours ]
