Summary
Developing curcumin (CUR) nanosuspensions using a novel, cost-effective method significantly enhances oral bioavailability. This approach improves drug solubility and permeability for insoluble compounds like CUR.
Area of Science:
- Pharmaceutical Sciences
- Materials Science
- Drug Delivery
Background:
- Nanosuspensions are key for improving oral bioavailability of poorly soluble drugs.
- Curcumin (CUR), a BCS class IV drug, shows promise but is limited by poor solubility and permeability.
- Conventional nanosuspension production methods can be complex and costly.
Purpose of the Study:
- To develop a cost-effective method for producing curcumin (CUR) nanosuspensions.
- To enhance the oral bioavailability of CUR.
- To investigate the physicochemical properties and in vitro/in vivo performance of CUR nanosuspensions.
Main Methods:
- Curcumin (CUR) nanosuspensions were prepared using a novel, cost-effective technique.
- Physicochemical characterization involved dynamic light scattering (DLS), transmission electron microscopy (TEM), differential scanning calorimetry (DSC), and X-ray diffraction analysis (PXRD).
- In vitro dissolution and in vivo pharmacokinetic studies were conducted using TPGS or Brij78 as stabilizers.
Main Results:
- Characterization confirmed the amorphous state of CUR in the nanosuspensions.
- In vitro dissolution of CUR nanosuspensions was significantly increased.
- Oral bioavailability of CUR increased 3.18-fold (CUR/TPGS) and 3.7-fold (CUR/Brij78) compared to CUR suspension.
Conclusions:
- The developed cost-effective method successfully produced CUR nanosuspensions with improved oral bioavailability.
- This method offers a fast, inexpensive, and efficient approach for preparing nanosuspensions of poorly soluble drugs.
- The findings support the potential of CUR nanosuspensions for enhanced therapeutic efficacy.

01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
1.9K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...

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...

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...

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 secretion,...

Oral drug delivery is the most common route of administration due to its convenience, cost-effectiveness, and high patient compliance. It enables precise formulation to ensure proper drug dosage and bioavailability. The development of oral dosage forms considers drug properties such as solubility, stability, and absorption to optimize therapeutic efficacy.Tablets, capsules, liquids, and chewable formulations enhance drug stability, mask undesirable tastes, and improve patient experience.

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 absorption...
