Insights

Researchers are developing novel lipid-based delivery systems for Amphotericin B (AmB) to improve its effectiveness and reduce side effects. These advanced formulations aim for better drug accessibility, potentially through oral administration, offering a breakthrough in treating serious fungal infections.

Area of Science:

  • Pharmacology
  • Drug Delivery Systems
  • Nanotechnology

Background:

  • Amphotericin B (AmB) is a critical antifungal and antileishmanial drug but faces limitations due to poor solubility and toxicity.
  • Conventional formulations cause severe side effects and nephrotoxicity, while liposomal versions are costly and require injection.
  • There is a significant need for safer, more accessible Amphotericin B formulations.

Purpose of the Study:

  • To review recent advancements in lipid-based delivery systems for Amphotericin B.
  • To focus on non-parenteral, nanoparticulate formulations developed in the last five years.
  • To highlight promising lipid systems currently in clinical trials.

Main Methods:

  • Literature review of recent scientific publications and clinical trial data.
  • Focus on lipid-based nanoparticulate systems for Amphotericin B delivery.
  • Analysis of formulations targeting improved efficacy and reduced toxicity.

Main Results:

  • Lipid systems show high affinity for Amphotericin B, enabling targeted delivery.
  • Non-parenteral formulations, particularly nanoparticulate ones, are under active investigation.
  • Several novel lipid-based systems are progressing towards or are in clinical trials.

Conclusions:

  • Lipid-based systems offer a promising strategy to overcome Amphotericin B's limitations.
  • Development of safe, cost-effective oral formulations is a key goal.
  • Continued research in this area could lead to improved treatment options for invasive fungal infections and leishmaniasis.

Drug Distribution: Tissue Binding01:21

Drug Distribution: Tissue Binding

Upon entering the systemic circulation, drugs can distribute into the interstitial and intracellular fluid of various tissue cells. This distribution is facilitated by the binding of drugs to different cellular components within tissues, which may lead to drug accumulation in specific areas. Drugs bound to tissue components serve as reservoirs that release free drugs back into the system, prolonging the drug's overall action. However, this accumulation can also result in local toxicity.

Pore Transport and Ion-Pair Transport

Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...

Bioavailability Enhancement: Drug Permeability Enhancement

Body:After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt...

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Routes of Drug Administration: Parenteral01:25

Routes of Drug Administration: Parenteral

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Drug Biotransformation: Overview01:16

Drug Biotransformation: Overview

Pharmaceutical substances known as xenobiotics are predominantly lipophilic and nonionized. This enables them to permeate lipid bilayers, such as cell membranes, and interact with intracellular target receptors. Lipophilic drugs have an advantage in crossing biological barriers and reaching their intended sites of action. However, lipophilic drugs often have a restricted capacity for renal expulsion or elimination from the body. When these drugs enter the kidneys and undergo glomerular...
