Introduction

Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) known for its analgesic and antipyretic properties. However, its clinical effectiveness is often limited by its low solubility, which restricts its systemic absorption and bioavailability. This research explores the hydrotropic solubilization technique as a feasible approach to enhance the solubility of ibuprofen, thereby improving its dissolution and overall therapeutic efficacy. The study specifically evaluates the solubility enhancement effects of the hydrotropic agent N,N-dimethylurea (DMU) in comparison to other commonly used hydrotropic agents.

Hydrotropic Solubilization Technique

Hydrotropy refers to the ability of certain substances, when present in high concentrations, to increase the aqueous solubility of sparingly soluble compounds like ibuprofen. This phenomenon occurs due to the interaction of hydrotropic agents, which possess both hydrophilic and lipophilic properties, leading to the formation of micelles that encapsulate and solubilize non-polar drugs. Several hydrotropic agents were evaluated in the study, including sodium acetate, sodium benzoate, sodium salicylate, and urea, with a particular focus on their unique solubilization capabilities. The preliminary findings established that urea significantly increased the solubility of ibuprofen when used at a 1M concentration.

Efficacy of Urea in Solubilization

Among the various hydrotropic agents tested, urea showcased the most substantial enhancement in ibuprofen solubility. The study revealed that with increasing concentrations of urea (0.5M to 2.0M), the solubility of ibuprofen rose dramatically from 2.237 mg/ml to 29.047 mg/ml, indicating a direct relationship between urea concentration and solubility enhancement. This marked increase in solubility by over 81% compared to distilled water exemplifies the potential of urea as a powerful solubilizing agent for poorly soluble drugs like ibuprofen.

Spectrophotometric Methods for Solubility Analysis

The research implemented a UV-VIS spectrophotometric method to quantify the solubility of ibuprofen in various hydrotropic solutions. A calibration curve was developed to ensure accurate absorbance measurements at a wavelength of 259 nm, facilitating the determination of drug concentration in solution. The study's systematic approach allows for the assessment of hydrotropic agent interference, ensuring the reliability of results obtained from spectrophotometric analyses. It highlights the potential of hydrotropic solubilization methods in formulating safer and more efficient analytical techniques for poorly soluble drugs.

Conclusion

The findings of this study underscore the effectiveness of hydrotropic solubilization techniques, particularly with agents like urea, in enhancing the aqueous solubility of ibuprofen. As a result, this approach offers a promising, cost-effective, and environmentally friendly alternative to traditional solubilization methods that often rely on organic solvents. The implications of these results extend beyond ibuprofen, suggesting that other poorly water-soluble drugs may benefit from similar solubilization strategies, paving the way for innovative formulations and improvements in bioavailability and therapeutic outcomes.
