Does Metronidazole Decrease Serum Lafame Levels?
There is no evidence that metronidazole affects serum "Lafame" levels, as "Lafame" does not appear to be a recognized medical term or laboratory parameter in standard clinical practice or the medical literature.
Clarification of the Question
The term "Lafame" is not identifiable as:
- A standard serum laboratory value
- A medication or drug compound
- A recognized biomarker or clinical parameter
- A metabolite or enzyme measured in routine or specialized testing
What Metronidazole DOES Affect
Based on FDA labeling and clinical evidence, metronidazole has documented effects on several laboratory values and drug interactions:
Laboratory Interference 1
Metronidazole can interfere with certain serum chemistry determinations, causing falsely low or zero values for:
- Aspartate aminotransferase (AST/SGOT)
- Alanine aminotransferase (ALT/SGPT)
- Lactate dehydrogenase (LDH)
- Triglycerides
- Hexokinase glucose
This interference occurs because metronidazole's absorbance peak (322 nm) is similar to NADH (340 nm) in enzymatic assays at pH 7.
Drug Level Interactions 1
Metronidazole can affect serum levels of other medications:
- Lithium: Can cause elevation of serum lithium levels, potentially leading to toxicity
- Warfarin: Potentiates anticoagulant effect (prolongs prothrombin time)
- Phenytoin: Impaired clearance reported
Metabolic Effects 2
One older study demonstrated metronidazole can reduce:
- Total serum cholesterol (by approximately 13-22%)
- LDL-cholesterol (by 21%)
Recommendation
If you intended to ask about a specific laboratory value or medication level, please clarify the correct term. Common possibilities that sound similar might include:
- Lipase
- Lactate
- Albumin
- Drug levels (e.g., lamotrigine, leflunomide)
If monitoring laboratory values in a patient on metronidazole, be aware of the potential for spurious results in enzymatic assays and consider lithium level monitoring if the patient is on concurrent lithium therapy 1.
