Fermented Polyherbal Formulation Restored Ricinoleic Acid-Induced Diarrhea in Sprague Dawley Rats and Exhibited In...

Area of Science:

• Pharmacology
• Microbiology
• Ethnobotany

Background:

• Antibiotic-resistant gastrointestinal pathogens significantly worsen diarrhea.
• Current treatments require augmentation with novel therapeutic strategies.
• Natural products offer a potential source for developing effective antidiarrheal agents.

Purpose of the Study:

• To develop and evaluate a polyherbal formulation (AP-01) for treating diarrhea caused by multiple antibiotic-resistant pathogens.
• To assess the safety and efficacy of AP-01 using an animal model and in vitro pathogen inhibition assays.
• To identify the phytochemical constituents responsible for the antidiarrheal and antimicrobial activities.

Main Methods:

• A hydroethanolic extraction method involving boiling and fermentation was used to prepare the polyherbal formulation AP-01 from selected plant parts.
• The safety and efficacy of AP-01 were evaluated in an animal model of diarrhea.
• In vitro studies were conducted to assess the formulation's effect on multiple antibiotic-resistant gastrointestinal pathogens and its cytotoxicity on normal gut cells.

Main Results:

• AP-01 demonstrated significant efficacy in relieving diarrhea symptoms by 79.71% in an animal model, comparable to a standard drug (83.01%).
• The formulation exhibited no cytotoxicity on normal gut cells and successfully inhibited the growth of antibiotic-resistant Enterobacteriaceae family pathogens in vitro at concentrations of 75–100 μl/ml.
• AP-01 was found to delay gastric motility, with diarrhea symptoms ceasing within 320.66 ± 5.05 minutes.

Conclusions:

• The polyherbal formulation AP-01 is a safe and effective agent against antibiotic-resistant gastrointestinal pathogens and infectious diarrhea.
• The presence of alkaloids, flavonoids, and polyphenols likely contributes to AP-01's synergistic multiple modes of action.
• Further research and development into AP-01 could lead to improved therapeutic options for infectious diarrhea, leveraging natural compounds.
