because degranulation causes release of substances like histamine, SRS, leukotienes. Can anyone name any others?.

ipratropium is the anticholinergic that can decrease resp secretions.

cimetidine is the H2 block used in PUD and gerd and inhibiting p450.

steroids work at the intranuclear receptor and inhibit transcription.

theophylline inh. phosphodiesterase and has a narrow T.I. causes adrenergic side effects
