Answer 1

1)Whats the advantage of Sublingual route over oral route?

The essential bit of leeway to sublingual administration is that the prescription is consumed by vessels that lead directly to your focal flow without a first go through the liver. This implies a quicker activity, just as frequently a higher blood prescription level, since the medicine isn't as a rule at first processed by the liver (accepting that it's a liver used medication, versus a renally discharged one).

On account of the mucous film underneath the tongue, the substance (on the off chance that it can break up in spit, generally this is unsettled) gets consumed snappier and straightforwardly into the circulatory system; instead of if you somehow managed to swallow it, it would need to be processed or endeavored to be processed first.

Now and again, however, a prescription requires the "principal go" to get dynamic - the drug itself is idle, yet has a functioning metabolite. The activity of these prescriptions would be eased back by being regulated sublingually.

2)What is First Pass Metabolism?

A first-pass impact is characterized as a low foundational accessibility of the medication because of huge digestion. Albeit a first-pass impact can happen in an assortment of tissues, including the digestion tracts Doherty and Pang (1997) and uterus De Ziegler et al (1997), it is frequently seen with the liver. Medication consumed from the gastrointestinal tract heads out quickly to the liver through the hepatic entry vein. Hepatic first pass happens when medication retained from the gastrointestinal tract is processed by compounds inside the liver to such a degree, that a large portion of the dynamic specialist doesn't leave the liver and, in this way, doesn't arrive at the systemic circulation.
