Hint: The given names are the different types of medicinal drugs that have been used to cure a variety of infections or diseases. Different drugs perform distinct and specific functions in our body and can therefore be used only for specific infections.

Complete answer:
A wide range of natural or synthetic medications are available to us. Different medicines can be categorized on many criterias. One such important basis of classification is based on the cure or the infection that is treated with the help of the drug. The functions performed by each drug can be written as follows:
Penicillin: an antibiotic
It is a strong antibacterial medication that works by destroying the cell walls of bacteria and restricting their ability to maintain a cell wall. It falls under the category of beta lactam antibiotics.
Aspirin: a non-narcotic analgesic
It is a member of a group of medications known as salicylates. It treats inflammation, pain and fever without inducing sleep.
Paracetamol: a non-narcotic analgesic
It serves the same purpose as that of Aspirin. It is also known as acetaminophen and helps in treating mild to moderate fever without inducing sleep.
Morphine: a narcotic analgesic
These drugs alter the way in which a response is received from the brain or the nervous system towards pain and is mainly used for treating severe pain. It affects the receptors and also induces sleep.

Note:
Even though most drugs perform limited and specific functions, certain medications are known as master drugs that do not treat any specific infection but help in reducing common symptoms like aches, fever or headache that can be caused by multiple reasons.
