SCENARIO 4

Does nitroglycerin have a high or low first pass effect? Please discuss why this is important to know and how it relates to bioavailability. What route has 100% bioavailability? In addition to parenterally, how can this medication be given to counter the first pass effect? Write a sample prescription for this medication.

The need for nitroglycerin and its ability to depict a high first-pass effect is confirmed. This means that if it is taken through the mouth there will be some contents of drugs to be metabolized by the liver before it comes to systemic circulation which will bring critically low oral bioavailability (Meunier et al., 2023).

The importance of this aspect of first-pass effect and bioavailability is helps in the calculation of the amount of drugs that will reach the target system in active form. When there are medicines that have high pass effects then other routes of administration will be used (Twiner et al., 2022).

The route that gives 100% bioavailability includes the intravenous (IV) route since the drugs are directed wired to the bloodstream hence bypassing the liver and other tissues that metabolize drugs. Countering these past effects of drugs can be solved using sublingual tablets, transdermal patches, and intravenous (IV) administration (Meunier et al., 2023).

A prescription sample of Nitroglycerin 0.4 mg of the sublingual tablets is administered by taking one tablet of this drug and placing it under the tongue when the chest pains start.
