Drugs are substances that alter the metabolic reactions in the living organisms. Morphine is an opioid drug extracted from the latex of Papaver somniferum.
On consumption of opioids, they bind to the proteins called opioid receptors found in the central nervous system (CNS), gut and other parts of the body. They act as CNS depressants slowing down body functions.
Morphine can decrease heart rate, blood pressure, respiratory rate and even show decreased responsiveness. This is because it decreases or slows down the activity of the CNS, thus acting as a depressant.
Morphine is generally administered either orally or intravenously. It binds to nerve cells of the CNS and inhibits the perception of pain. It is commonly used in pain management and provides significant pain relief in patients who have undergone surgery.
Morphine acts as a sedative by inducing sleep, however it plays no direct role in reducing fever.
