new treatment for Chronic hepatitis B

Tenofovir a  nucleotide analogue can now be used for treating CHB,,, can anyone tell me abt the nephrotoxicity profile of the drug

[naic]

do you mean that Tenofovir can make HBsAg positive to HBsAg negative? is that for real?

[zellyf]

No, it reduces viral load.

I would try googling tenofovir with nephrotoxic.

New Onset or Worsening Renal Impairment

Tenofovir is principally eliminated by the kidney. Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported with the use of VIREAD [See ADVERSE REACTIONS].

It is recommended that creatinine clearance be calculated in all patients prior to initiating therapy and as clinically appropriate during therapy with VIREAD. Routine monitoring of calculated creatinine clearance and serum phosphorus should be performed in patients at risk for renal impairment.

Dosing interval adjustment of VIREAD and close monitoring of renal function are recommended in all patients with creatinine clearance <50 mL/min [See DOSAGE AND ADMINISTRATION]. No safety or efficacy data are available in patients with renal impairment who received VIREAD using these dosing guidelines, so the potential benefit of VIREAD therapy should be assessed against the potential risk of renal toxicity.

VIREAD should be avoided with concurrent or recent use of a nephrotoxic agent.
