It is a synthetic chemotherapeutic agent that is effective against a broad spectrum of [[Gram-positive bacteria|Gram-positive]] and [[Gram-negative bacteria|Gram-negative]] bacteria. Pefloxacin is commonly used in the treatment of [[urinary tract infections]], [[respiratory tract infections]], and [[gastrointestinal infections]].


Pefloxacin works by inhibiting the bacterial enzymes [[DNA gyrase]] and [[topoisomerase IV]], which are required for bacterial DNA replication, transcription, repair, and recombination.
==Mechanism of Action==
Pefloxacin works by inhibiting bacterial [[DNA gyrase]] and [[topoisomerase IV]], enzymes that are essential for [[DNA replication]] and [[transcription (genetics)|transcription]]. This inhibition leads to the disruption of bacterial [[DNA synthesis]], ultimately resulting in bacterial cell death.


== Uses ==
==Pharmacokinetics==
Pefloxacin is well absorbed from the [[gastrointestinal tract]] and reaches peak plasma concentrations within 1 to 2 hours after oral administration. It is widely distributed throughout the body, including penetration into [[cerebrospinal fluid]], making it effective for treating [[central nervous system infections]]. The drug is metabolized in the [[liver]] and excreted primarily in the [[urine]].


Pefloxacin is used to treat severe and life-threatening bacterial infections such as [[pneumonia]], [[urinary tract infections]], [[gonorrhea]], and [[skin infections]]. It is also used in the treatment of [[tuberculosis]] when first-line drugs cannot be used.
==Clinical Uses==
Pefloxacin is indicated for the treatment of various infections, including:
* [[Urinary tract infections]]
* [[Respiratory tract infections]]
* [[Gastrointestinal infections]]
* [[Skin and soft tissue infections]]
* [[Bone and joint infections]]


== Side Effects ==
==Side Effects==
Common side effects of pefloxacin include [[nausea]], [[vomiting]], [[diarrhea]], and [[abdominal pain]]. Serious side effects may include [[tendonitis]] and [[tendon rupture]], particularly in older adults and those on concurrent [[corticosteroid]] therapy. [[Photosensitivity]] reactions and [[central nervous system]] effects such as [[dizziness]] and [[headache]] have also been reported.


Like all medicines, Pefloxacin can cause side effects, although not everybody gets them. The most common side effects include [[nausea]], [[diarrhea]], [[vomiting]], and [[rash]]. In rare cases, it can cause serious side effects like [[tendon rupture]], [[photosensitivity]], and [[QT prolongation]].
==Contraindications==
Pefloxacin is contraindicated in patients with a known hypersensitivity to [[quinolones]] and in those with a history of [[tendon disorders]] related to quinolone use. It should be used with caution in patients with [[renal impairment]] and [[hepatic impairment]].


== Precautions ==

* [[Fluoroquinolone]]
Pefloxacin should be used with caution in patients with a history of [[tendon disorders]] related to fluoroquinolone treatment. It should not be used in patients with a history of [[epilepsy]] or [[seizures]]. It should also be avoided in patients with known [[QT interval prolongation]] or patients who are taking other drugs that prolong the QT interval.

Pefloxacin is a fluoroquinolone antibiotic used to treat a variety of bacterial infections. It is a synthetic chemotherapeutic agent that is effective against a broad spectrum of Gram-positive and Gram-negative bacteria. Pefloxacin is commonly used in the treatment of urinary tract infections, respiratory tract infections, and gastrointestinal infections.

Mechanism of Action

Pefloxacin works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes that are essential for DNA replication and transcription. This inhibition leads to the disruption of bacterial DNA synthesis, ultimately resulting in bacterial cell death.

Pharmacokinetics

Pefloxacin is well absorbed from the gastrointestinal tract and reaches peak plasma concentrations within 1 to 2 hours after oral administration. It is widely distributed throughout the body, including penetration into cerebrospinal fluid, making it effective for treating central nervous system infections. The drug is metabolized in the liver and excreted primarily in the urine.

Clinical Uses

Pefloxacin is indicated for the treatment of various infections, including:

Side Effects

Common side effects of pefloxacin include nausea, vomiting, diarrhea, and abdominal pain. Serious side effects may include tendonitis and tendon rupture, particularly in older adults and those on concurrent corticosteroid therapy. Photosensitivity reactions and central nervous system effects such as dizziness and headache have also been reported.

Contraindications

Pefloxacin is contraindicated in patients with a known hypersensitivity to quinolones and in those with a history of tendon disorders related to quinolone use. It should be used with caution in patients with renal impairment and hepatic impairment.
