Form II of this drug was recently discovered in co-crystallization experiments with an epilepsy drug, and its active component can interfere with chloride levels to induce hearing loss and tinnitus.  A newly discovered mechanism of its action involves stimulation of lipoxins to then form nitric oxide, while a more established mechanism involves its irreversible binding to a serine residue on the cyclo-oxygenases; this binding prevents the formation of thromboxane A2, which is needed for platelet aggregation, as well as prostaglandins. For 10 points, name this drug that can cause Reye's syndrome in children, a pain-reliever also known as acetylsalicylic acid.
