Match List I with List II

(i)-(c); (ii)-(d); (iii)-(a); (iv)-(b)

The correct answer is option 1. (i)-(c); (ii)-(d); (iii)-(a); (iv)-(b)

Here is the explanation for each of the following match:

(i) Ranitidine: (c) Antihistamine

Ranitidine is a medication used to treat ulcers in the stomach and intestines. It belongs to a class of drugs called H2 blockers, which work by reducing the production of stomach acid. While it doesn't directly block histamine receptors like traditional antihistamines, it indirectly inhibits the release of histamine from certain cells in the stomach lining.

(ii) Furacine: (d) Antiseptic

Furacine is a topical antiseptic medication used to prevent and treat bacterial infections in wounds, burns, and cuts. It contains the active ingredient nitrofurazone, which has broad-spectrum antimicrobial properties and helps prevent the growth of bacteria on the skin's surface.

(iii) Phenelzine: (a) Tranquilizer

Phenelzine is a medication used to treat depression and anxiety disorders. It belongs to a class of drugs called monoamine oxidase inhibitors (MAOIs), which work by increasing the levels of certain neurotransmitters in the brain, such as serotonin, norepinephrine, and dopamine. While it has calming effects, it is not typically classified as a tranquilizer.

(iv) Chloramphenicol: (b) Antibiotic

Chloramphenicol is a broad-spectrum antibiotic used to treat various bacterial infections, including bacterial conjunctivitis, meningitis, typhoid fever, and certain types of pneumonia. It works by inhibiting bacterial protein synthesis, thereby preventing the growth and reproduction of bacteria.

Summary:
The correct matches are:

Ranitidine: Antihistamine

Furacine: Antiseptic

Phenelzine: Tranquilizer

Chloramphenicol: Antibiotic
