If not treated aggressively these events may become rapidly fatal. Several toxins can induce such non-infection-based temperature disturbances through different underlying mechanisms. The drugs involved in the eruption of these syndromes include sympatho-mimetics and monoamine oxidase inhibitors antidopaminergic agents anticholinergic compounds serotonergic agents medicaments with the capability of uncoupling oxidative phosphorylation inhalation anesthetics and unspecific agents causing drug fever. Besides centrally disturbed regulation disorders hyperthermia often results as a consequence of intense skeletal muscle hypermetabolic reaction. This leads mostly to rapidly evolving muscle rigidity extensive rhabdomyolysis electrolyte disorders and renal failure and may be fatal. The goal of treatment is to reduce body core temperature with both symptomatic supportive care including active cooling and specific treatment options. Introduction Body temperature regulation is complex and requires a balance between heat production and dissipation. Hyperthermia occurs when metabolic heat production exceeds heat dissipation. Many exogenously administered drugs are capable of altering the body s ability to maintain a constant temperature. Normal body temperature is approximately C although this varies with the time of day. The Society of .
