Lamivudine / tenofovir Disease Interactions

There are 6 disease interactions with lamivudine / tenofovir:

Major

Nrtis (Includes Lamivudine/tenofovir) ↔ Hepatotoxicity

Severe Potential Hazard, Moderate plausibility

Applies to: Alcoholism, Liver Disease

Hepatotoxicity including lactic acidosis, severe hepatomegaly with steatosis, fulminant hepatitis, and hepatic failure has rarely been associated with the use of nucleoside reverse transcriptase inhibitors (NRTIs) alone or in combination with other antiretroviral agents. Therapy with NRTIs should be administered cautiously in patients with preexisting liver disease, a history of alcohol abuse, or hepatitis. Therapy should be suspended if clinical or laboratory findings suggestive of lactic acidosis or pronouced hepatotoxicity occur.

Nrtis (Includes Lamivudine/tenofovir) ↔ Pancreatitis

Severe Potential Hazard, Moderate plausibility

Applies to: Hyperlipidemia, Pancreatitis, Alcoholism

The reverse transcriptase inhibitors, didanosine (ddI), zalcitabine (ddC), stavudine (d4T) and lamivudine (3TC), may cause pancreatitis. The incidence is generally low but is approximately 7% with ddI, and up to 15% in pediatric patients given 3TC. Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with these agents. Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.

Nrtis (Includes Lamivudine/tenofovir) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Patients with clinically significant renal impairment may be at greater risk for toxicities and adverse effects from nucleoside reverse transcriptase inhibitors (NRTIs) due to decreased drug clearance. Dosage adjustments are recommended. In addition, these patients should be monitored closely during NRTI therapy, and dosages adjusted further if necessary.

Tenofovir (Includes Lamivudine/tenofovir) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Tenofovir is primarily eliminated by the kidney via glomerular filtration and active tubular secretion. Renal impairment, including acute renal failure and Fanconi syndrome, has been reported with tenofovir use. Close monitoring of renal function and lengthening the dosing interval are recommended for patients with creatinine clearance less than 50 mL/min. Creatinine clearance should be calculated in all patients before starting tenofovir treatment and during treatment when clinically appropriate. Routine monitoring of serum creatinine and phosphorus is recommended for patients at risk of or with a history of renal dysfunction. Safety and effectiveness have not been evaluated in patients with renal insufficiency using dose adjustments; therefore, the benefit of tenofovir treatment should be weighed against the risk of renal toxicity. Tenofovir should be avoided in patients who are currently using or have recently used nephrotoxic drugs.

Moderate

Tenofovir (Includes Lamivudine/tenofovir) ↔ Bone Toxicity

Moderate Potential Hazard, Moderate plausibility

Applies to: Osteoporosis, Vitamin D Deficiency

Osteomalacia and reduced bone mineral density have been reported in animal toxicology studies involving tenofovir exposures 6- to 12-fold those observed in humans. The mechanism of bone toxicity has not been established, and it is not known if long-term use of tenofovir disoproxil fumarate will cause bone abnormalities in humans.

Moderate

Tenofovir (Includes Lamivudine/tenofovir) ↔ Liver Disease

Minor Potential Hazard, Low plausibility

Applies to: Liver Disease

There are no data concerning the use of tenofovir disoproxil fumarate in patients with hepatic impairment. Tenofovir and tenofovir disoproxil are not metabolized by liver enzymes. However, since tenofovir is not entirely eliminated by the kidney (70% to 80%), tenofovir pharmacokinetics may be altered in patients with impaired hepatic function.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
