Hypotension cocaine abuse

Amphetamines have also been associated with a syndrome of acute kidney injury and rhabdomyolysis. Several series have described patients following intravenous injection of methamphetamine or phenmetrazine who presented with hyperactivity, fever, chills, sweats, abdominal cramps, diarrhea, and hypotension [177,178]. The patients have developed acute kidney injury which is usually oliguric and associated with classic rhabdomyolysis, similar to cases of cocaine-induced rhabdomyolysis. Several patients have had disseminated intravascular coagulation and liver function abnormalities as well. Methamphetamine abuse has also been associated with accelerated hypertension, unexplained chronic renal failure, acute lead poisoning (a common reagent used in its production utilizes lead acetate) and at least one case of biopsy proven interstitial nephritis the latter patient responded to intravenous corticosteroids but whether the nephritis was truly due to amphetamines remains unproven [179].
