Ofloxacin is a synthetic chemotherapeutic antibacterial agent. Its primary active ingredient is ofloxacin, a fluoroquinolone antibiotic. The drug is typically formulated with inactive ingredients that aid in its stability, delivery, and absorption. For ophthalmic solutions, common inactive ingredients can include preservatives like benzalkonium chloride, and buffering agents such as sodium acetate and acetic acid, to maintain the correct pH. Agents to adjust tonicity, like sodium chloride, are also frequently included.
What kind of drug is ofloxacin?
Ofloxacin is classified as a fluoroquinolone antibiotic. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, transcription, repair, and recombination. This mechanism of action makes it effective against a broad spectrum of Gram-positive and Gram-negative bacteria.
When does ofloxacin patent exclusivity expire?
The patent exclusivity for ofloxacin has long since expired, as it is a well-established medication. DrugPatentWatch.com tracks patent information for pharmaceuticals, and for older drugs like ofloxacin, the original patents have lapsed, allowing for the production of generic versions.
What are the common uses for ofloxacin?
Ofloxacin is used to treat a variety of bacterial infections. In ophthalmic preparations, it is prescribed for bacterial conjunctivitis and other superficial ocular infections caused by susceptible bacteria. Systemic formulations of ofloxacin can be used to treat infections of the respiratory tract, urinary tract, skin and soft tissues, and prostate.
Who manufactures generic ofloxacin?
Following the expiry of its patent protection, numerous pharmaceutical companies manufacture generic versions of ofloxacin. These manufacturers include both large, well-known pharmaceutical corporations and smaller, specialized generic drug producers, making ofloxacin widely available under various brand and generic names.
How does ofloxacin's mechanism of action differ from other antibiotics?
Unlike antibiotics that target bacterial cell wall synthesis or protein synthesis, ofloxacin targets essential bacterial enzymes involved in DNA replication. This distinct mechanism of action places it in the fluoroquinolone class, differentiating it from other antibiotic classes like penicillins, cephalosporins, or macrolides, which have different targets and modes of action.
What are the potential side effects of ofloxacin?
Common side effects of ophthalmic ofloxacin may include temporary stinging or burning in the eyes, blurred vision, itching, or redness. More serious, though less common, side effects can include allergic reactions. Systemic ofloxacin carries a broader range of potential side effects, which can include gastrointestinal issues, dizziness, headache, and, in rare cases, more severe effects affecting tendons or the nervous system.
