Paritaprevir

Paritaprevir is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Paritaprevir rather than just read about it. In short: Paritaprevir (previously known as ABT-450) is an acylsulfonamide inhibitor of the NS3-4A serine protease manufactured by Abbott Laboratories that shows promising results as a treatment of hepatitis C. When given in combination with ritonavir and ribavirin for 12 weeks, the rate of sustained virologic response at 24 weeks after treatment has been estimated to be 95% for those with hepatitis C virus genotype 1.

Key takeaways

Paritaprevir belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Paritaprevir to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Paritaprevir from memory before moving on to harder problems.

Reference excerpt

Paritaprevir (previously known as ABT-450) is an acylsulfonamide inhibitor of the NS3-4A serine protease manufactured by Abbott Laboratories that shows promising results as a treatment of hepatitis C. When given in combination with ritonavir and ribavirin for 12 weeks, the rate of sustained virologic response at 24 weeks after treatment has been estimated to be 95% for those with hepatitis C virus genotype 1. Resistance to treatment with paritaprevir is uncommon, because it targets the binding site, but has been seen to arise due to mutations at positions 155 and 168 in NS3. Paritaprevir was a component of Viekira Pak and Technivie. In May 2018, the FDA announced that Technivie and Viekira were to be discontinued. The discontinuation was voluntary and not related to the safety, quality, or efficacy of the medicine. It was estimated that both medications would be available until January 1, 2019.

Worked examples

Example 1 — a first encounter with Paritaprevir

Start with the simplest possible case. Write down what Paritaprevir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Paritaprevir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Paritaprevir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Paritaprevir

In research: Paritaprevir appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Paritaprevir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Paritaprevir is common in secondary-school and first-year university syllabi. It links to neighbouring topics Acylsulfonamides, Anti-infective agent stubs, Cyclopropyl compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Paritaprevir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Paritaprevir in simple terms?

Why does Paritaprevir matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Paritaprevir?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
