Revefenacin

Revefenacin is a science 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 Revefenacin rather than just read about it. In short: Revefenacin, sold under the brand name Yupelri, is a medication for the treatment of chronic obstructive pulmonary disease (COPD). It was approved for use in the United States in 2018.

Key takeaways

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

Reference excerpt

Revefenacin, sold under the brand name Yupelri, is a medication for the treatment of chronic obstructive pulmonary disease (COPD). It was approved for use in the United States in 2018. It was developed by Theravance Biopharma and is marketed by Mylan. Revefenacin is formulated as a solution that is nebulized and inhaled. Revefenacin is a bronchodilator that exerts its effect as a long-acting muscarinic antagonist.

Society and culture

Brand names In some countries, Yupelri is marketed by Viatris after Upjohn merged with Mylan to create Viatris.

Synthesis The synthesis of revefenacin was recently reported.

The reaction between 1-benzylpiperidin-4-ol [4727-72-4] (1) and 1-isocyanato-2-phenylbenzene [605-677-1] (2) gave the urethane [171723-80-1]. Next acid transfer hydrogenation cleaved the benzyl protecting group to give [171722-92-2] (3). The reductive amination with Cbz-sarcosinal [107201-33-2] (4). Catalytic hydrogenation then removed the Cbz group to give [743460-48-2] (5). Amide formation with 4-formylbenzoic acid [619-66-9] (6) gave [864760-28-1] (7). Lastly, a reductive amination reaction with isonipecotamide [39546-32-2] (8) completed the synthesis of revefenacin (9).

Worked examples

Example 1 — a first encounter with Revefenacin

Start with the simplest possible case. Write down what Revefenacin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Revefenacin 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 Revefenacin 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 Revefenacin

In research: Revefenacin appears in science 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 Revefenacin 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: Revefenacin is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benzamides, Biphenyls, Bronchodilators, so understanding it makes those chapters shorter.
In everyday life: Look for Revefenacin 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.
