<prompt> Drug induced pemphigus is seen in all exceptPenicillinPhenoptheleinIodineFrusemide  <response>: D i.e. Frusemide- Induced pemphigus is induced by radiotherapy PV PF , thermal burns and electrical injury PV, vegetables of Allium group, Human herpes virus 8 DNA and drugs.- Drug induced pemphigus usually resembles PF PV and is caused by thiol sulphydryl and non thiol containing drugs biochemical and immunological mechanisms respectively. The sulfhydryl group in desmoglein 1,3 becomes more antigenic because of interference of sulfhydryl group of thiol drugs. So the prognosis is better upon drug withdrawl of thiol group drugs.Drugs containing thiol sulphydryl group such as penicillamine, captopril, enalaprilQ are most commonly associated with drug induced pemphigus Harrison. Non thiol drugs linked to pemphigus include - penicillinsQ, cephalosporins, piroxicam, pyrazolam derivatives eg. phenylbutazone, propranolol, chloroquine, hydroxy chloroquine, rifampicin, montelukast, interferon, other ACE inhibitors eg enalapril, ramapril, fosinopril and angiotension II receptor blockers condesaan and telmisaan Rooks. Iodine radioactive non radioactive and phenopthaleinQ may also lit pemphigus.
