Atropine and scopolamine
Dilate and fix pupil (no accommodation, fixed at far vision)
Mydriatic and cycloplegic effects
Indications, considerations, and AE of topical ocular steroids
Used to reduce inflammation (esp post-procedure)
Need to taper and use minimal effective concentration
AE: cataracts, possible rise in IOP, increased susceptibility to infections (sometimes prescribed with an antibiotic)
Considerations with ocular topical NSAIDs

MOA of acyclovir
2-deoxyguanosine analog; gets converted by thymidine kinase and inhibits viral DNA synthesis
Tx for oral candidiasis
Infants:
Nystatin topical oral solution
Treat mom with azole cream
Others: best compliance with PO fluconazole, but nystatin is technically 1st line
MOA of -azoles
Inhibition of fungal CYP450 enzymes = reduced ergosterol synthesis
Considerations with nasal steroids
Inhibit late stage of allergic rhinitis (tissue remodeling); not good for quick relief
