Introduction
Dicyclomine Hydrochloride (DIC) is an antimuscarinic and antispasmodic medication primarily used to alleviate symptoms associated with irritable bowel syndrome and smooth muscle spasms in the gastrointestinal and urinary tract. It is known for a dual mechanism of action: exhibiting anticholinergic effects at acetylcholine-receptor sites and directly relaxing smooth muscles. DIC is formulated in various pharmaceutical products, and while numerous analytical methods for simultaneous estimation exist, methods specifically for determining DIC alone are limited. This review aims to compile and assess various analytical techniques for estimating DIC in both pharmaceutical dosage forms and biological samples.
Spectrophotometric Methods
Among the various analytical techniques, spectrophotometry is a prominent method used for the quantitative determination of DIC. Bebawy et al. developed a spectrophotometric methodology that involves creating colored complexes through the interaction of DIC with π-acceptors like 2, 3-dichloro-5, 6-dicyano-p-benzoquinone (DDQ) and chloranil. The assay measurements occur at specific wavelengths (456 nm for DDQ, 530 nm for p-chloranilic acid, and 650 nm for chloranil), producing different color densities based on DIC concentrations. This method is not only reliable but also adheres to Beer's law over a defined concentration range, making it a valuable tool for the analysis of DIC in various formulations.
Chromatographic Techniques
Chromatographic methods, including gas-liquid chromatography (GLC) and high-performance thin-layer chromatography (HPTLC), also play a crucial role in the analysis of DIC. GLC was utilized for content uniformity determination in capsules and tablets, demonstrating precision comparable to established pharmacopeial procedures. Meanwhile, HPTLC has proven effective for quantifying DIC in injection formulations, achieving linear responses across a significant concentration range. The methods established in these chromatographic techniques are noted for their sensitivity, simplicity, and accuracy, thereby making them suitable for routine quality control of DIC in pharmaceutical applications.
Potentiometric Analysis
Potentiometric methods have been employed to analyze DIC in various matrices such as serum, urine, and milk. In these methods, specialized plastic membrane electrodes encapsulating DIC ion associations have been developed, exhibiting near-Nernstian responses. The assessments of DIC concentrations using potentiometric analysis are recognized for their good selectivity and operational ease. The successful application of these methods underscores their reliability for both pharmaceutical formulations and biological sample analysis, adding to the comprehensive toolkit available for DIC quantification.
Conclusion
In conclusion, this review highlights a range of analytical methods developed for the determination of DIC in pharmaceutical dosage forms and biological samples. Various techniques, including spectrophotometry, chromatography, and potentiometry, demonstrate promise in terms of precision and reliability. DIC remains an essential therapeutic agent, especially for treating colic pain across different age groups. Despite the existing methods, there is ample opportunity for the development of simpler and more efficient analytical techniques that focus on the unique properties of DIC, further enhancing its application in clinical settings and ensuring accurate dosing in therapeutic use.
