STABILITY STUDIES OF NITROGLYCERINE IN DIFFERENT DOSAGE FORMS (AS PER ICH GUIDELINES)three types that is physical, chemical and microbial stability.Nitroglycerin different dosage form like sublingual tablets,Injectionand ointment were studied over a 135 days period to determinestability in terms of loss ...
If a significant change occurs at any time during the 6 months’ testing at the accelerated condition, additional testing at the intermediate storage condition should be conducted and evaluated. A significant change for a drug substance or product as per ICH guideline is defined as follows: •...
All test interval plans that use the storage conditions of a stability study must be either a base interval plan or an overlay of the base interval plan assigned to the storage condition plan. Define interval periods as the testing frequencies required by the storage condition....
Sterility tests were performed on days 30 or 180 to detect the presence of microbial contamination using a pool of three batches for each condition. Samples were incubated in trypticase soy broth (TSB) and fluid thioglycolate medium (FTM, both from Merck KGaA), and incubated at 25 and 37 °...
as well as the selection of test methods at each stability time point presented in the table, a minimum of 232 DP vials will be required to perform the stability study as planned at just the intended storage condition (< minus 60 degrees C), monitoring DP stability for up to 36...
Further work by the ICH Stability Working Group led to the idea of a single long-term stability condition for Zone IV countries which would also serve as an intermediate condition/alternative long-term condition for Zone II countries. Their proposal to use 30...

For each condition, the number of timepoints tested should allow the accurate calculation of the rate of degradation “k.” This can be achieved for example using the “kinetic model” approach, the “shape parameter” approach or the “isoconversion” approach (as described in Section 3). Ob...
Finally, optimum temperature was selected to be 30 °C, since all peaks were properly resolved under this condition, Fig. 3. Different detection wavelengths 230.0, 254.0, 260.0 and 321.0 nm were tested to determine the best one for the studied analyte in term of sensitivity and peak shape. ...
