Why is sublingual faster than oral?

Thickness of oral epithelium: As the thickness of sublingual epithelium is 100‐200 μm which is less as compared to buccal thickness. So the absorption of drugs is faster due to thinner epithelium and also the immersion of drug in smaller volume of saliva.

Can metoprolol be given sublingual?

Metoprolol is probably swallowed after intranasal and sublingual administration and absorbed in the gastrointestinal tract.

Which drug can not given by oral route due to first pass metabolism?

Commonly used drugs that undergo extensive first pass metabolism are cimetidine, lidocaine, propranolol, nitroglycerin, diazepam, midazolam, morphine, pethidine, imipramine, and buprenorphine. Some drugs like insulin are destroyed by the gastric secretions and therefore cannot be given orally.

Which drug Administration Routes avoid first pass metabolism in the liver?

Intravenous injection is the most common parental route of medication administration and has the benefit of bypassing the first-pass metabolism by the liver.

Can sublingual tablets be taken long-term?

These drugs are not metabolized in the liver since they are not passing in the digesting system. Therefore, you may take a lower dosage and still get equivalent results. Smoking, drinking or eating while using sublingual medication can affect the drug absorption and how efficient the results would be.
