The speed of absorption just after nasal insufflation is proscribed by cocaine-induced vasoconstriction of capillaries during the nasal mucosa. Onset of absorption soon after oral ingestion is delayed since cocaine is usually a weak base using a pKa of eight.6, and it is Therefore within an ionized sort that may be badly absorbed in the acidic belly and simply absorbed in the alkaline duodenum.[11] The rate and extent of absorption from inhalation of cocaine is analogous or higher than with intravenous injection, as inhalation offers access directly to the pulmonary capillary bed.
