Nasal spray

<p>Nasal sprays are used to deliver medications <a href="/facts/Route_of_administration/LsyoHTzH">locally</a> in the <a href="/facts/Nasal_cavities/N82Yw4LR">nasal cavities</a> or <a href="/facts/Systemic_administration/yxye1dtm">systemically</a>. They are used locally for conditions such as <a href="/facts/Nasal_congestion/xClWzxrg">nasal congestion</a> and <a href="/facts/Allergic_rhinitis/ukE6bkIs">allergic rhinitis</a>. In some situations, the <a href="/facts/Nasal_administration/W0hvb0gd">nasal delivery route</a> is preferred for systemic therapy because it provides an agreeable alternative to injection or pills. Substances can be assimilated extremely quickly and directly through the nose.[<i>unreliable medical source?</i>] Many pharmaceutical drugs exist as nasal sprays for systemic administration (e.g. <a href="/facts/Sedative/JWzvq66P">sedative</a>-analgesics, treatments for <a href="/facts/Migraine/5XaE1W25">migraine</a>, <a href="/facts/Osteoporosis/xa1W00Tj">osteoporosis</a> and <a href="/facts/Nausea/dyhkcbeD">nausea</a>). Other applications include <a href="/facts/Hormone_replacement_therapy/d3KW80rn">hormone replacement therapy</a>, treatment of <a href="/facts/Alzheimer%2527s_disease/w7Ad6tdg">Alzheimer's disease</a> and <a href="/facts/Parkinson%2527s_disease/xpekKj6x">Parkinson's disease</a>. Nasal sprays are seen as a more efficient way of transporting drugs with potential use in crossing the blood–brain barrier.
