T44: Poisoning by drugs primarily affecting the autonomic nervous system

Poisoning by drugs primarily affecting the autonomic nervous system is a group of conditions caused by the inadvertent or intentional misuse of certain medications. The autonomic nervous system, which regulates body functions like heart rate, digestion, and temperature, can be disrupted by these drugs, leading to varied symptoms. In the initial stages, a person may experience abnormal heart rhythms, fluctuating blood pressure, difficulties in breathing, and disturbances in digestion such as vomiting or diarrhea. As the condition progresses, more serious effects can occur including loss of consciousness or even life-threatening crises such as a heart attack. These conditions can result from an overdose of the drug, a heightened sensitivity to normal doses in some individuals, or interaction with other medications or substances. The range of affected substances includes medications used for asthma, a variety of heart conditions, certain types of eye surgery, as well as certain poisons.
