PHARMACEUTICAL APPLICATIONS OF HPTLC AND METHOD VALIDATION
HPTLC as an analytical technique has applications in multiple fields. It can be used for qualification and quantification of samples in sectors like Pharmaceuticals, Herbals, Cosmetic, Food and Forensic sciences and it can also be used as a fingerprint analysis technique in the above fields. HPTLC instrumentation involves different modules for application, development, image documentation and detection.
Application of HPTLC
in pharmaceutical field: As all the compounds which are analysed by TLC can be
analysed using HPTLC, it has a wide variety of applications in the
Pharmaceutical field.
1. Impurity profiling
2. Content Uniformity
3. Forced Degradation
4. Stability
5. Limit test
6. Assay
Validation of a method
is very important as it tests the suitability of the method and makes sure that
there are no errors. HPTLC
Analysis Analytical
method validation is essential in the Pharmaceutical field and the ICH Q2
guidelines speak in detail regarding the types of analytical procedures that
need to be validated, viz.:
1. Identification tests
2. Quantitative tests for impurities content
3. Limit test for the control of impurities
4. Quantitative tests for the active moiety in
samples of drug substance or drug product or other selected components in the
drug product
It is also important
to understand the objective of the analytical procedure based on which the
validation characteristics will be evaluated.
One such example of
validation done using CAMAG HPTLC is that of Cyclobenzaprine HCl, which is
a skeletal muscle relaxant used to treat muscle spasms, strains, sprains and
other muscle injuries.
The analytical method
was developed and validated for linearity, robustness & ruggedness,
specificity, LOD & LOQ and the following results were obtained:
· Linearity: 4.826 mg Cyclobenzaprine HCl in the
given sample of tablet
· Recovery: 98%
· LOD: 160.60 Nano grams
· LOQ: 486.69 Nano grams
