Nasal route
If a drug is to be breathed in and absorbed through the thin mucous membrane that lines the nasal passages, it must be transformed into tiny droplets in air (atomized). Once absorbed, the drug enters the bloodstream. Drugs administered by this route generally work quickly. Some of them irritate the nasal passages. Drugs that can be administered by the nasal route includenicotine(for smoking cessation),calcitonin(for osteoporosis),sumatriptan(for migraine headaches), and corticosteroids (for allergies).
