OMDR vs Pharma — Key differences for NEET MDS
Wickham striae = white lacy lines = Lichen planus pathognomonic. Reticular LP = most common form. Erosive LP = most symptomatic painful. Butterfly rash = malar rash = SLE pathognomonic. Band of IgG at BMZ = Lupus band test. Lichenoid drug reaction mimics LP = gold NSAIDs ACE inhibitors.

Onset determined by pKa = lower pKa faster onset. Duration determined by protein binding = higher binding longer duration. Articaine = unique hybrid amide with ester group. Prilocaine = least toxic amide. Bupivacaine = most cardiotoxic.
