Strepsils

Strepsils 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 Strepsils rather than just read about it. In short: Strepsils is a brand of throat lozenges manufactured by British company Reckitt Benckiser. Strepsils throat lozenges are used to relieve discomfort caused by mouth and throat infections.

Key takeaways

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

Reference excerpt

Strepsils is a brand of throat lozenges manufactured by British company Reckitt Benckiser. Strepsils throat lozenges are used to relieve discomfort caused by mouth and throat infections.

Ingredients The primary active ingredients are dichlorobenzyl alcohol and amylmetacresol, with some formulations containing ascorbic acid (vitamin C). Inactive ingredients include menthol, tartaric acid, and propylene glycol. Strepsils Extra rather contains Hexylresorcinol.

History Strepsils was originally introduced in 1950 by Boots Healthcare as a mouthwash. Strepsils throat lozenges were introduced in 1958. Strepsils was one of the Boots Healthcare brands acquired by Reckitt Benckiser in 2006. Strepsils have been in production since 1958 and contain two active ingredients, namely: amylmetacresol and 2,4-dichlorobenzyl alcohol. These ingredients are mild antiseptics that can kill bacteria associated with mouth and throat infections. However, as indicated in the package, research has not demonstrated that the presence of an antibacterial agent reduces the duration or severity of an infection. Extra Strepsils contains hexylresorcinol as an active ingredient and strepsils sore throat and nose covered contains menthol 8 mg. Reckitt Benckiser also produces a higher-resistance pill that used to be marketed under the Strepsils Intensive label, but is now marketed under the Strepfen brand, which contains the active ingredient flurbiprofen 8.75 mg. In Australia, Argentina and Hungary, 'Strepsils Plus' are available, which contain lidocaine, as well as the antiseptic agents present in original Strepsils. In France and Spain they are also available with lidocaine, marketed as 'Strepsils Lidocaine'. The name of Strepsil comes from the Streptococcus bacterium that causes certain types of sore throat.

Strepsils are sold in Italy under the Benagol brand. In Germany they are sold as Dobendan and Dobensana brand, and from 2009 to 2013 were sold as Dobendan Strepsils. In Norway they are sold without active ingredients under the Repsil brand. In North America, they are sold under the Cēpacol brand.

Dose The recommended dose is a tablet every 2–3 hours for adults. Vitamin C is added for Strepsils Vitamin C-100. Each Strepsils Vitamin C-100 pill contains 1.2 mg of 2,4-dichlorobenzyl alcohol, amylmetacresol 0.6 mg and 100 mg of vitamin C.

Worked examples

Example 1 — a first encounter with Strepsils

Start with the simplest possible case. Write down what Strepsils 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 Strepsils 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 Strepsils 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 Strepsils

In research: Strepsils 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 Strepsils 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: Strepsils is common in secondary-school and first-year university syllabi. It links to neighbouring topics Reckitt brands, Throat lozenges, so understanding it makes those chapters shorter.
In everyday life: Look for Strepsils 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.
