What is the method called for administering a drug into the nose?

The method of administering a drug into the nose is known as nasal administration. This route allows for the delivery of medications directly through the nasal mucosa, which can provide rapid absorption into the bloodstream. This can be particularly beneficial for certain medications that need to take effect quickly, bypassing the digestive system and liver metabolism, which can diminish the effectiveness of oral medications. Nasal administration can be employed for various drug types, including decongestants, hormones, and vaccines, among others. This method is also less invasive compared to other routes of administration and can enhance patient compliance when compared to injections or oral medications.
