$CODE / $BKLLF ~ Oral mucosal delivery can reduce the dosing frequency of chloroquine (CQ) and hydroxychloroquine (HCQ) which is currently administered orally 2-3 times a day. Moreover, in oral mucosal drug delivery, the drug is delivered slowly and continuously throughout the duration of oral application hence there are no peaks and troughs in drug plasma concentration which are associated with multiple dose administration in a day. With respect to CQ and HCQ, it is expected that adverse effects in patients will be less with the oral mucosal delivery as drug plasma concentration with oral mucosal delivery is less than peak plasma concentration associated with oral tablets.
