What is the best route for administering respiratory drugs?

Intravenous administration is the best way to deliver a precise dose quickly and in a well-controlled manner throughout the body. It is also used for irritating solutions, which would cause pain and damage tissues if given by subcutaneous or intramuscular injection.

What is the route of administration that delivers a drug directly to the lungs?

2.5 Pulmonary Administration Route Pulmonary drug delivery offers several advantages in the treatment of respiratory diseases over other routes of administration. Inhalation therapy enables the direct application of a drug within the lungs.

Which route of administration delivers a drug most quickly?

Intravenous (IV)
Intravenous (IV) drug use in which the drug is injected directly into a vein and enters the bloodstream to reach the brain. This is the quickest way of achieving a psycho-active drug effect. The drug effect is experienced in less than one minute.

Why are drugs administered by different routes?

A medication administration route is often classified by the location at which the drug is applied, such as oral or intravenous. The choice of routes in which the medications are applied depends not only on the convenience but also on the drug’s properties and pharmacokinetics.

What are the advantages of a pulmonary drug delivery route?

Pulmonary drug delivery routes present several advantages compared to conventional drug administration, such as fewer systemic side effects than oral or parenteral administration. Many studies show drug delivery systems that are intended for pulmonary administration. However, the time that these systems stay at the mucose surfaces is limited.

Why is drug delivery so complex in the lungs?

Pulmonary drug delivery is relatively complex because the respiratory tract has evolved defense mechanisms to keep inhaled drug particles out of the lungs and to remove or inactivate them once deposited.

Which is the most efficient route of drug delivery?

Pulmonary drug deliveryappears to be the easy route of administration as this allows the delivery of drugs directly into the lungs and hence drug deposition through this route is more efficient due to the large absorptive surface area (between 70 and 100 m2) and the thinness of the alveolar epithelium (between 0.5 and 1.0 μm).

How is the inhalation route of Drug Administration used?

The inhalation route is used for a local effect or systemic effect. The drug is inhaled through the mouth and delivered into the lungs.
