INTRANASAL ADMINISTRATIONS Meaning and
Definition
-
Intranasal administration refers to the delivery of medication or other substances through the nasal cavity. It involves the instillation or application of a drug formulation directly into the nose, where it is absorbed into the systemic circulation.
This method of administration offers several advantages. The nasal cavity is highly vascularized, meaning it has a rich blood supply, which allows for rapid absorption of the drug. Additionally, the nasal mucosa, which lines the nasal cavity, contains cilia and mucus that can help trap and remove foreign particles, reducing the risk of systemic side effects or drug interactions.
Intranasal administration is commonly used for drugs that require rapid onset of action or are poorly absorbed through the gastrointestinal tract, such as certain nasal decongestants, allergy medications, or anti-migraine drugs. It may also be used for systemic delivery of certain medications, bypassing the need for injection.
The technique of intranasal administration involves the use of various devices, including nasal sprays, drops, or powders. These formulations are designed to facilitate drug delivery into the nasal cavity, optimizing absorption and distribution.
However, intranasal administration also has limitations. Nasal congestion, nasal discharge, or anatomical abnormalities may affect drug delivery and absorption. Additionally, some drugs may have poor stability or unpleasant taste when administered intranasally, limiting their feasibility for this route.
Overall, intranasal administration provides an effective and convenient means of delivering drugs, offering potential advantages over other routes of administration such as oral or injectable.
