Introduction
Acetyl-l-carnitine (Nicetile® fiale; Biofutura Pharma S.p.A., Sigma Tau group, Milano, Italy) is a compound widely used for the treatment of many diseases, such as neuropathies, diabetic polyneuropathy, and Parkinson’s disease. It is frequently administered via the intramuscular route with other drugs, such as steroidal anti.inflammatories, muscle relaxants, and vitamins.
Methods
In the present study the behavior of acetyl-l-carnitine injections (Nicetile® fiale) with different drugs used for combined therapy was studied. Physicochemical properties including color, clarity, pH, and drug content were observed before and after mixing at room temperature.
Results
The content of all the active drugs after mixing remained optimal within 10% of their nominal values.
Conclusions
The measurements demonstrate the physicochemical compatibility between Nicetile fiale and the other tested products, meaning that there is no evidence of interactions and degradation.
