3. AIM AND OBJECTIVE OF STUDY
• To develop a simple accurate and precise method for
Verapamil in drug substances and drug product and to validate
the method as per ICH guidelines.
5. • DESCRIPTION: A calcium channel blocker that is a class IV
anti-arrhythmia agent.
• SOLUBILITY: SOLUBLE IN WATER,METHANOL
• MECHANISM OFACTION: Verapamil inhibits voltage-
dependent calcium channels. Specifically, its effect on L-type
calcium channels in the heart causes a reduction in ionotropy
and chronotropy, thuis reducing heart rate and blood pressure.
Verapamil's mechanism of effect in cluster headache is thought
to be linked to its calcium-channel blocker effect, but which
channel subtypes are involved is presently not known.

9. METHOD DEVELOPMENT STEPS IN RP-HPLC
ANALYTICAL METHOD DEVELOPMENT:
• Method development usually requires selecting the method
requirements and deciding on what type of instrumentation to
utilize and why.
• The wide variety of equipment, columns, eluent and
operational parameters involved makes HPLC method
development .
10. There are several reasons for developing new methods of
analysis:
1. A suitable method for particular analyte in the specific matrix
is not available.
2. Existing methods may be too error or they may be unreliable
(have poor accuracy or precision)
3. Existing methods may be too expensive, time consuming.
11. HPLC method development generally follows the following
steps:
Step 1-selection of the HPLC method and initial system.
Step2-Selection of optimum conditions.
Step3-selectivity optimization.
Step4-system parameter optimization.
Step5-method validation.
14. VALIDATION PARAMETERS OF RP-HPLC
Typical validation characteristics which should be
considered are listed below:-
1.Accuracy
2. Precision
a. repeatability
b. intermediate precision
3. specificity
4. Detection limit
5. Quantitation limit
6. Linearity
7. range.
