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 ...
Allyone's Stability Chambers have a reputation to quickly achieve & maintain the defined setpoint to simulate the condition perfectly & flawlessly with extraordinary control on both Temperature & Humidity along with outstanding uniformity. Our Stability Chambers are conceptual... ...
which we have already found from the final condition in equation (29). Therefore, as Fedorov states [24], for a trigonal crystal, only three necessary and sufficient conditions are required: $$ c_{11} > \left | c_{12} \right |,\qquad (c_{11} + c_{12})c_{33} > 2c_{13}...
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 inSection 3). Obta...
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...
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: •...
which refers to the condition at which the ions are effectively immobilized when the scan rate is much quicker than the diffusion rate51. The difference between slow (steady-state) and fast scan speeds can be directly attributed to the movement of mobile ions and is referred to as mobile ion...
The ICH defines the mean kinetic temperature as being “a single derived temperature that, if maintained over a defined period of time, affords the same thermal challenge to a drug substance or drug product as would be experienced over a range of both higher and lower temperatures for an eq...
Accelerated stability study (Temperature: 40 °C ± 2, Relative Humidity (RH): 75% ± 5) and real time stability study (Temperature: 25 °C ± 2, Relative Humidity (RH): 60% ± 5) was conducted as per ICH guideline Q1A (R2). The change in organoleptic parameters, physic-chemical ...
