Oxiracetam (ISF 2522) is a water-soluble ampakine of the nootropic racetam chemical class. Oxiracetam is a positive AMPA modulator similar in mechanism and potency (but not the binding site) to both piracetam and aniracetam but may have an additional benefit of increasing glutamate, acetylcholine, and D-aspartic acid release from activated but not resting neurons. Oxiracetam has been proved as an efficient memory enhancer if taken consistently. Additionally, studies have revealed positive impacts on demented patients in the long term. Thus, the drug enhances an overall quality of life of patients suffering from ADHD, dementia, and other neurological problems. Oxiracetam is one of the most popular nootropics, well known and highly regarded for its outstanding cognitive enhancement properties and mild stimulant capability. It has also been proven to be safe and well tolerated even at high dosages, and its moderate cost, ready availability and “stackability” make it a must-have for many nootropic users.

To record currents through Ca2+ channels, a whole cell variation of the patch-clamp technique was applied to NG108-15 cells. Step depolarizations lasting 160 milliseconds were applied to a holding potential of −50 mV to induce high-voltage– activated (HVA) Ca2+ channel currents. Under such experimental conditions, low-voltage–activated (LVA) Ttype Ca2+ channels were practically inactivated at the end of the pulse, allowing us to measure the amplitude of N/L-type Ca2+ channel currents. The external and internal (pipette-filling) solutions were designed to separate Ca2+ channel currents from other ionic currents
