Pill Oesophagitis (oesophagitis caused by drugs)

Certain drugs, particularly those of the tetracycline group, lodge in the gullet when they are not taken down with enough water and cause local damage and ulceration; oesophagitis from drugs — pill oesophagitis — develops in this way.

In the pictures below you see the damage caused in the gullet by drugs. In the first picture the mark left by a drug that lodged in the gullet can be made out.
