Insights

This study highlights a novel method for treating patients using intracavitary instillation of amphotericin B guided by computed tomography (CT). The addition of iohexol injection enhances drug delivery accuracy, offering a promising technique for targeted antifungal therapy.

Area of Science:

  • Medical Imaging
  • Pharmacology
  • Infectious Diseases

Background:

  • Intracavitary drug instillation is a method for localized treatment.
  • Accurate delivery of antifungal agents is crucial for effective therapy.
  • Existing methods may have limitations in precision.

Purpose of the Study:

  • To describe a novel technique for intracavitary drug instillation.
  • To evaluate the utility of computed tomography (CT) guidance in this procedure.
  • To assess the impact of iohexol injection on the accuracy of amphotericin B delivery.

Main Methods:

  • Computed tomography (CT)-guided intracavitary instillation of amphotericin B.
  • Concurrent administration of iohexol for enhanced visualization.
  • Case report detailing the procedural steps and outcomes.

Main Results:

  • The combined use of CT guidance and iohexol injection facilitated precise localization of the target cavity.
  • Amphotericin B was successfully instilled with improved accuracy.
  • The technique was found to be feasible and rarely reported previously.

Conclusions:

  • CT-guided intracavitary amphotericin B instillation with iohexol offers a highly accurate method for targeted drug delivery.
  • This approach represents a valuable, albeit uncommon, therapeutic option for specific clinical scenarios.
  • Further research may explore broader applications of this technique.

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...
