The scarring of the small blood vessels, called capillary sclerosis, is the initial lesion of analgesic nephropathy. [7] Found in the renal pelvis, ureter, and capillaries supplying the nephrons, capillary sclerosis is thought to lead to renal papillary necrosis and, in turn, chronic interstitial nephritis.

Lysine acetylsalicylate, also known as aspirin DL-lysine or lysine aspirin, is a more soluble form of acetylsalicylic acid (aspirin). As with aspirin itself, it is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, antithrombotic and antipyretic properties. [ 1 ]
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances, both toxic chemicals and medications, on kidney function. [1] There are various forms, [2] and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity.
[citation needed] A dose of 40 mg of aspirin a day is able to inhibit a large proportion of maximum thromboxane A 2 release provoked acutely, with the prostaglandin I2 synthesis being little affected; however, higher doses of aspirin are required to attain further inhibition. [15]
These differential effects are due to the different roles and tissue localisations of each COX isoenzyme. [11] By inhibiting physiological COX activity, NSAIDs may cause deleterious effects on kidney function, [12] and, perhaps as a result of water and sodium retention and decreases in renal blood flow, may lead to heart problems.

The toxic effects of salicylates have been described since at least 1877. [5] In 2004, more than 20,000 cases with 43 deaths were reported in the United States. [1] About 1% of those with an acute overdose die, while chronic overdoses may have severe outcomes. [3] Older people are at higher risks of toxicity for any given dose. [5]
Symptoms can vary from person to person. Someone in early stage kidney disease may not feel sick or notice symptoms as they occur. When the kidneys fail to filter properly, waste accumulates in the blood and the body, a condition called azotemia. Very low levels of azotemia may produce few, if any, symptoms.
