Abstract:
Lymphomatoid drug reactions are relatively rare, with no gender, race, or age predilection. The condition generally may be divided into 2 broad categories with some overlap: (1) drug-induced pseudolymphoma and (2) anticonvulsant-induced pseudolymphoma syndrome, marked by the triad of papular to nodular skin lesions, fever, and lymphadenopathy. While a vast array of pharmacologic agents has been linked to lymphomatoid drug reactions, our case represents the first reported incidence of methylphenidate hydrochloride--a ubiquitously prescribed medication for attention deficit hyperactivity disorder--causing a pseudolymphoma.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...
