Insights

This study enhanced the solubility and dissolution of meloxicam (MLX), a non-steroidal anti-inflammatory drug, using solid dispersions with skimmed milk. This formulation shows potential for treating gastric disturbances.

Area of Science:

  • Pharmaceutical Sciences
  • Drug Delivery Systems

Background:

  • Meloxicam (MLX) is a water-insoluble non-steroidal anti-inflammatory drug (NSAID) and selective COX-2 inhibitor.
  • Poor aqueous solubility limits the therapeutic efficacy and formulation options for MLX.

Purpose of the Study:

  • To enhance the aqueous solubility and dissolution rate of meloxicam.
  • To investigate the potential of solid dispersions with skimmed milk for improving MLX properties.

Main Methods:

  • Preparation of physical mixtures and solid dispersions of MLX with skimmed milk.
  • Utilized rotary vacuum evaporation technique for solid dispersion preparation.
  • Characterization using Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM).

Main Results:

  • Solid dispersions significantly increased MLX aqueous solubility (approximately threefold) compared to the pure drug.
  • Dissolution rate was notably improved for solid dispersions versus physical mixtures and pure MLX.
  • Analytical techniques confirmed the formation of meloxicam-skimmed milk solid dispersions.

Conclusions:

  • Solid dispersion with skimmed milk effectively enhances meloxicam solubility and dissolution.
  • The presence of amino acids and surfactants in skimmed milk contributes to solubility enhancement.
  • This approach offers a promising strategy for formulating water-insoluble drugs like MLX for potential gastrointestinal applications.

Factors Influencing Drug Absorption: Pharmaceutical Parameters

Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Factors Affecting Dissolution: Drug Permeability, Stability and Stereochemistry

Orally administered drugs primarily enter the systemic circulation via passive diffusion through the intestinal membranes. The drug's absorption is influenced by drug stability in the gastrointestinal GI tract, membrane permeability, the surface area available for absorption, luminal drug concentration, and residence time in the lumen. Drug permeability can be enhanced by adjusting the lipophilicity, polarity, or molecular size of the drug, promoting its passive transport across intestinal...

Drug Dissolution: Requirements and Profile Comparison

The acceptance criteria for dissolution profile data are anchored in Q values, representing the percentage of drug dissolved within a specified period. This assessment unfolds in three stages:First Stage: The test passes if all six drug dosage units are equal to or greater than Q plus 5%; otherwise, the sample proceeds to the second stage.Second Stage: The average of twelve units must be equal to or greater than Q, with no unit falling below Q - 15% to pass; if not, it progresses to the final...

Factors Affecting Dissolution: Particle Size and Effective Surface Area

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 employed to...
