“Cell incubation with increasing concentrations of galantamine (10–300 nm) or melatonin (0.3–10 nm) for 24 hr, followed by a 24‐hr period with R/O, caused a concentration‐dependent protection; maximum protection was achieved with 300 nm galantamine (56% protection) and 10 nm melatonin (50% protection).”
“Combination of subeffective concentrations of melatonin (0.3 nm) and galantamine (30 nm) caused a synergistic and significant protection that was similar to the maximum protection afforded by effective concentrations of melatonin or galantamine alone.”
“This investigation evaluated a possible synergistic neuroprotective effect of subeffective concentrations of combined galantamine and melatonin.”
