Summary
Amorphous beta-carotene (BC) solid dispersion significantly enhances BC absorption and bioavailability in rats due to improved water solubility. This method offers a solvent-free approach for pharmaceutical and food applications.
Area of Science:
- Nutritional Science
- Pharmacokinetics
- Materials Science
Background:
- Beta-carotene (BC) is a vital nutrient found in fruits and vegetables, known for its pharmacological benefits.
- Low water solubility limits the bioavailability of BC, hindering its effective utilization.
- Previous research developed an amorphous BC solid dispersion with enhanced solubility using hot-melt technology.
Purpose of the Study:
- To investigate the pharmacokinetic profile of amorphous BC solid dispersion.
- To evaluate the enhanced absorption and bioavailability of BC for functional food applications.
Main Methods:
- Oral administration of crystalline or amorphous BC to rats.
- Plasma BC concentration measurement using High-Performance Liquid Chromatography (HPLC).
- Pharmacokinetic parameter calculation using a novel method without organic solvents or surfactants.
Main Results:
- Amorphous BC demonstrated significantly increased absorption in rats compared to crystalline BC.
- The study successfully calculated pharmacokinetic parameters under physiological conditions.
- Bioavailability of orally administered BC was effectively determined.
Conclusions:
- Amorphous BC solid dispersion improves BC absorption and bioavailability.
- The developed technology enhances BC solubility without organic solvents, applicable to pharmaceutical and food industries.
- This approach holds significant utility value for improving BC's efficacy.

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...

Body:Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...

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...

Body:Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug...

Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...

01:27Pharmaceutical Alternatives: Polymorphic Form-Related and Particle Size-Related Therapeutic Nonequivalence
104
Changes in polymorphic forms can significantly influence the bioavailability of poorly soluble drugs. Although the FDA defines pharmaceutical equivalence based on having the same active ingredient, dosage form, and route of administration, it does not automatically disqualify products with different polymorphic forms. This means two products with different polymorphs can still be deemed pharmaceutically equivalent. However, polymorphic differences can affect properties like wettability,...
