How do antiseptics differ from disinfectants? Give one example of each.

Antiseptics and disinfectants are both used in daily lives since they are effective against harmful microorganisms. Antiseptics are applied to the living tissues such as wounds, cuts, ulcers, and diseased skin surfaces, while disinfectants are applied only to non-living objects such as floors, drainage system, instruments, etc. Disinfectants are harmful to living tissues. Examples of antiseptics are dettol, tincture of iodine and the examples of disinfectants are chlorine, potassium permanganate, 1 % solution of phenol.

While antacids and antiallergic drugs interfere with the function of histamines, why do these not interfere with the function of each other?

Specific drugs affect some specific receptors. Antacids and anti-allergic drugs work on different receptors. This is the reason why antacids and anti-allergic drugs do not interfere with each other functions but interfere with the functions of histamines. Secretion of histamine causes allergy.
