Let us look into each drug and its use:

A. Phenelzine : (III) Antidepressant

Phenelzine is a type of monoamine oxidase inhibitor (MAOI). MAOIs work by increasing the levels of neurotransmitters such as serotonin and norepinephrine in the brain, which helps alleviate symptoms of depression. It is prescribed for major depressive disorder and other mood disorders. Therefore, Phenelzine is classified as an antidepressant.

B. Terfenadine : (II) Antihistamine

Terfenadine is a second-generation antihistamine that was used to relieve symptoms of allergies such as runny nose, sneezing, and itchy eyes. It works by blocking histamine H1 receptors, which are responsible for allergy symptoms. Although it has been largely replaced by newer antihistamines due to safety concerns, it is still recognized for its antihistamine properties.

C. Codeine : (IV) Analgesics

Codeine is an opioid medication used to treat mild to moderate pain and to relieve cough. As an analgesic, it helps in pain management by interacting with opioid receptors in the brain. It is commonly used in combination with other medications to enhance pain relief or reduce coughing.

D. Salvarsan : (I) Antibiotic

Salvarsan, also known as arsphenamine, was one of the first antibiotics used to treat syphilis. It is an organoarsenic compound and was a breakthrough in the treatment of bacterial infections before the advent of modern antibiotics. Its discovery marked a significant advancement in the treatment of bacterial diseases.
