The both opioid and narcotics are used to manage the pain (intense pain).

Question 2

Answer

Difference between semisynthetic and fully synthetic opioids

Semisynthetic opioids

Fully synthetic opioids

These are derived or synthesized from natural opioids by modifications of functional groups

These are synthesized from a chemical process

Examples are fentanyl, pethidine, methadone, tramadol, and loperamide

They do not develop addiction and dependence
