Ofloxacin

Ofloxacin 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 Ofloxacin rather than just read about it. In short: Ofloxacin, sold under the brand name Floxin among others, is a quinolone antibiotic useful for the treatment of a number of bacterial infections. When taken by mouth or injection into a vein, these include pneumonia, cellulitis, urinary tract infections, prostatitis, plague, and certain types of infectious diarrhea.

Key takeaways

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

Reference excerpt

Ofloxacin, sold under the brand name Floxin among others, is a quinolone antibiotic useful for the treatment of a number of bacterial infections. When taken by mouth or injection into a vein, these include pneumonia, cellulitis, urinary tract infections, prostatitis, plague, and certain types of infectious diarrhea. Other uses, along with other medications, include treating multidrug resistant tuberculosis. An eye drop may be used for a superficial bacterial infection of the eye and an ear drop may be used for otitis media when a hole in the ear drum is present. When taken by mouth, common side effects include vomiting, diarrhea, headache, and rash. Other serious side effect include tendon rupture, numbness due to nerve damage, seizures, and psychosis. Use in pregnancy is typically not recommended. Ofloxacin is in the fluoroquinolone family of medications. It works by interfering with the bacterium's DNA. Ofloxacin was patented in 1980 and approved for medical use in 1985. It is on the World Health Organization's List of Essential Medicines. Ofloxacin is available as a generic medication. In 2023, it was the 169th most commonly prescribed medication in the United States, with more than 2 million prescriptions.

Medical uses Ofloxacin is used in the treatment of bacterial infections such as:

Acute bacterial exacerbations of chronic obstructive pulmonary disease (COPD) Community-acquired pneumonia Uncomplicated skin and skin structure infections Nongonococcal urethritis and cervicitis Epididymitis Mixed Infections of the urethra and cervix Acute pelvic inflammatory disease Uncomplicated cystitis Complicated urinary tract infections Prostatitis Acute, uncomplicated urethral and cervical gonorrhea Ofloxacin has not been shown to be effective in the treatment of syphilis. Fluoroquinolones, the class of drug ofloxacin belongs to, were the drug of choice for treating gonorrhea in the 1980s; However, due to the development of fluoroquinolone-resistant Neisseria gonorrhoeae, fluoroquinolones were no longer used to treat gonorrhea by the late 1990s. As of 2004, the failure of single dose ofloxacin to treat gonorrhea has been reported in the United States, United Kingdom, Canada, and Australia.

Susceptible bacteria According to the product package insert, ofloxacin is effective against these microorganisms: Aerobic Gram-positive microorganisms:

Staphylococcus aureus (methicillin-susceptible strains) Streptococcus pneumoniae (penicillin-susceptible strains) Streptococcus pyogenes Aerobic Gram-negative microorganisms

Citrobacter koseri (Citrobacter diversus) Enterobacter aerogenes Escherichia coli Haemophilus influenzae Klebsiella pneumoniae Neisseria gonorrhoeae Proteus mirabilis Pseudomonas aeruginosa Other microorganisms:

Chlamydia trachomatis

Worked examples

Example 1 — a first encounter with Ofloxacin

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

In research: Ofloxacin 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 Ofloxacin 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: Ofloxacin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1,4-di-hydro-7-(1-piperazinyl)-4-oxo-3-quinolinecarboxylic acids, 4-Methylpiperazin-1-yl compounds, Cyclic ethers, so understanding it makes those chapters shorter.
In everyday life: Look for Ofloxacin 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 Ofloxacin in simple terms?

Why does Ofloxacin 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 Ofloxacin?

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.
