The correct answer is Oxycodone.
Oxycodone refers to a drug, which is generally prescribed in certain cases to treat severe pain. At lower doses, it leads to fatigue, memory loss, headache, itching, anxiety, and constriction of the pupil. At higher doses, Oxycodone causes lowered heart rate, slowed or stopped breathing that may eventually lead to unconsciousness and death.
In addition, it can also result in inhibition of blood flowing in specific regions of the circulatory system. This can eventually result in organ failure, loss of muscle control, and gangrene.
