Does adefovir cause nephrotoxicity?
Adefovir dipivoxil is an oral prodrug of adefovir that is effective against lamivudine-resistant HBV mutants. Adefovir was originally developed as an antiretroviral agent for HIV at a dosage of 60–120 mg daily, but was not preferred later due to high incidence of nephrotoxicity, occurring in 22–50% of patients.
Is lamivudine nephrotoxic?
Background: Lamivudine is one of the anti-hepatitis B virus (HBV) agents to prevent HBV recurrence after transplantation because lamivudine is safe for long-term use. However, nephrotoxicity is one of the adverse effects of lamivudine.
What is the treatment for nephrotoxicity?
Nephrotoxicity from IL-2 is generally reversible and managed by administering fluid boluses at the onset of oliguria [95,96]. Additionally, vasopressors such as low and intermediate-dose dopamine are used in treatment of oliguria and hypotension by cross-talk with adrenergic receptors [97,98].
Do antivirals affect the kidneys?
Antiviral drugs cause renal failure through a variety of mechanisms. Direct renal tubular toxicity has been described with a number of new medications with unique effects on epithelial cells of the kidney. These include cidofovir, adefovir dipivoxil, and tenofovir, as well as acyclovir.
Which drugs are nephrotoxic?
Certain drugs are inherently nephrotoxic and include aminoglycosides, amphotericin B, cisplatin, contrast dye, and cyclosporine. For others, such as those associated with chronic interstitial nephritis and crystal deposition, nephrotoxicity is dose dependant or related to prolonged duration of treatment.
Which ARV drug causes renal toxicity?
Antiretroviral therapy given in combination with low-dose ritonavir seems to increase the renal toxicity of indinavir [52].
Is tenofovir nephrotoxic?
Abstract. Tenofovir disoproxil fumarate (TDF, commonly termed ‘tenofovir’) is the antiretroviral most commonly implicated in antiretroviral-induced nephrotoxicity.
How does acyclovir cause nephrotoxicity?
Acyclovir-induced nephrotoxicity is typically evident by an increase in the plasma creatinine level, abnormal urine sediment, or acute renal injury [8]. Acyclovir is rapidly excreted in the urine via glomerular filtration and tubular secretion, and reaches high concentrations in the tubular lumen.
How do you prevent acyclovir nephrotoxicity?
The risk of acyclovir induced nephropathy can be minimized with empiric IV fluids to establish euvolemia before drug administration, avoiding rapid infusion of the drug (infuse slowly over 1-2 hours), and adjusting the dose for renal function if necessary [1].
Is ciprofloxacin nephrotoxic?
Drug-induced nephrotoxicity is one of the leading causes of acute kidney injury worldwide. Nephrotoxicity of ciprofloxacin is often underestimated. In addition to causing acute kidney injury, chronic drug toxicity can in some cases lead to chronic kidney disease and eventually end-stage renal disease.
What are the most common nephrotoxic drugs?
Drugs most often associated with this pathogenic mechanism of nephrotoxicity include antiplatelet agents (e.g., clopidogrel [Plavix], ticlopidine [Ticlid]), cyclosporine, mitomycin-C (Mutamycin), and quinine (Qualaquin).
Can lamivudine cause kidney problems?
Lamivudine (3TC) There have been multiple case reports of renal injury associated with ART including 3TC. One report describes two separate male patients who developed acute renal failure and pancreatitis.
Which tenofovir is less nephrotoxic?
Tenofovir alafenamide (TAF) is novel prodrug of Tenofovir, a nucleotide reverse transcriptase inhibitor. TAF is less nephrotoxic than its predecessor prodrug, tenofovir disoproxil fumarate (TDF).
Why is tenofovir nephrotoxic?
Proximal tubular cell secretion of tenofovir explains the accumulation of the drug in these mitochondria-rich cells. Tenofovir nephrotoxicity is characterized by proximal tubular cell dysfunction that may be associated with acute kidney injury or chronic kidney disease.
What medications are toxic to kidneys?
What Meds Might Hurt My Kidneys?
- Antibiotics.
- Diuretics.
- Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
- Proton Pump Inhibitors (PPIs)
- Supplements.
- Laxatives.
- If You Have Kidney Disease, Other Medications Can Be Harmful.
Is oral acyclovir nephrotoxic?
Acyclovir is an important antiviral agent in the therapy of herpes simplex and varicella zoster virus infections [6]. Although the drug is well tolerated, severe nephrotoxicity, which often leads to acute renal failure, has been observed in patients [4, 7].
Is acyclovir toxic to kidneys?
Acute kidney injury is a well-described side effect of acyclovir, the most common mechanism being crystal nephropathy. Unfortunately, although the side-effects of acyclovir are well known, they are often underappreciated.
