Hypothesis
The study aims to examine the interaction of local anaesthetic drugs used in ophthalmology with model DOPA-melanin in the presence of metal ions.
Conclusion
The presence of Cu2+ and Zn2+ ions decreases the total amount of local anaesthetics bound to melanin, potentially affecting their clinical therapeutic efficiency.
Supporting Evidence
- The analyzed drugs form complexes with melanin biopolymer.
- The order of drug affinity to melanin was found to be tetracaine > procaine >> bupivacaine > lidocaine.
- Cu2+ and Zn2+ ions decrease the total amount of local anaesthetics bound to melanin.
Takeaway
This study looks at how certain metal ions can change how local anaesthetic drugs stick to melanin, which is important for eye treatments.
Methodology
The study involved synthesizing melanin and testing the binding of local anaesthetics to melanin in the presence of metal ions.
