Abstract

Insights

Moxifloxacin effectively penetrates uterine tissue, reaching concentrations adequate for eradicating common pelvic inflammatory disease (PID) pathogens. This antibiotic demonstrates safety and tolerability for PID treatment.

Area of Science:

  • Pharmacology
  • Infectious Diseases
  • Gynecology

Background:

  • Pelvic inflammatory disease (PID) is a serious infection.
  • Effective antibiotic penetration into uterine tissue is crucial for PID treatment.
  • Moxifloxacin is a broad-spectrum antibiotic.

Purpose of the Study:

  • To assess moxifloxacin's uterine tissue penetration.
  • To determine if moxifloxacin concentrations are sufficient to treat PID pathogens.

Main Methods:

  • Prospective, multicenter, open-label study.
  • Single 400-mg intravenous dose of moxifloxacin administered.
  • Uterine tissue and plasma concentrations measured at 1, 2, 4, 7, and 24 hours post-infusion.

Main Results:

  • Moxifloxacin achieved significant uterine tissue accumulation.
  • Peak concentrations in plasma and tissue occurred at 1 hour.
  • Tissue-to-plasma ratios ranged from 1.7 to 2.1 over 24 hours.
  • Moxifloxacin was safe and well-tolerated.

Conclusions:

  • Achieved uterine tissue concentrations of moxifloxacin exceed minimum inhibitory concentrations for common PID pathogens.
  • Moxifloxacin is a promising therapeutic option for PID.

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
Uterine Tubes01:16

Uterine Tubes

The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...
Inhibitors of Bacterial DNA Synthesis01:28

Inhibitors of Bacterial DNA Synthesis

Bacterial pathogens depend on precise and efficient DNA replication to sustain infection. Two type II topoisomerases—DNA gyrase and topoisomerase IV—are critical to this process, as they resolve DNA supercoiling and unlink chromosomes during replication. Fluoroquinolones, synthetic derivatives of quinolones, exploit this mechanism by stabilizing the transient DNA–enzyme cleavage complex, preventing strand religation, and causing lethal double-strand breaks. These antibiotics are selectively...
Uterus and Cervix01:18

Uterus and Cervix

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...
Physiological Barriers01:25

Physiological Barriers

Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...
