Match the classes of drugs given in Column I with their action given in Column II.
(i) Analgesic – (e) Pain killing effect
Analgesic falls under the group of drugs which is used to achieve analgesia, which is relief from pain. They act on our peripheral and central nervous system. Analgesics reduce or abolish pain without causing any disturbances to the nervous system. So, they have a pain killing effect. E.g. Morphine.
(ii) Antiseptics – (f) Applied to diseased skin surfaces
Antiseptics are substances which stop or slow down microbial growth. Therefore it is an antimicrobial substance. They are applied to living tissues or to our skin to reduce the possibility of infections. So they can also be applied to diseased skin surfaces. E.g. Hydrogen peroxide, iodine, boric acid.
(iii) Antihistamines – (d) Prevents the interaction of histamine with its receptor
Antihistamines, from the name itself, we get to know that it has ‘anti effect’. It means that it shows the inhibitory effect whenever histamine comes in contact to its receptor , or in other words, antihistamines prevent the binding of the receptor by blocking the binding sites of the receptor. They are anti-allergic drugs. E.g. Seldane.
(iv) Antacids – (g) Treatment of acidity
Antacids are substances which are used to neutralize the acids produced in stomach. Also it helps in relieving heat burns, indigestions and other problems. E.g. Milk of magnesia.
(v) Tranquilizers – (b) Treatment of stress
Tranquilizers are basically drugs which are used for treatment of anxiety, tension, fear or any disturbance of mind and helps in sleeping. It is therefore an antidepressant as it helps in restoring the balance of neurotransmitters in our brain. E.g. Phenelzine (C8H12N2) or Nardil.
(vi) Antibiotics – (a) Inhibit the growth of microorganisms can be given orally.
Antibiotics are powerful medicines which are used to kill bacteria or inhibit their growth. Thus they help in fighting bacterial infections. It is used in the alternative treatment of meningitis, typhoid, dysentery, pneumonia. Along with that it is also used as an eye ointment for conjunctivitis. They can be given orally due to their low toxicity. If we are not sure the predictability of oral supply, then we can do it intravenously as well. E.g. amoxicillin, doxycycline, cephalexin.
(vii) Disinfectants – (c) Applied to inanimate objects.
Disinfectants are antimicrobial agents applied to non-living or inanimate objects so as to destroy the microorganisms living on that object. But they are harmful if they are applied on human tissue or skin as our skin is very sensitive and disinfectants would cause some ill effects on our skin. So to stop the microbial outgrowth on our skin, antiseptics are used which are milder as compared to disinfectants. E.g. Formaldehyde, glutaraldehyde, hydrogen peroxide, peracetic acid.
