The basic intent of my work was to develop accelerated stability-indicating Non-Pharmacopoeial method for check of Cholecalciferol tablets and to understand the drug assay stableness at different intervals at accelerated climatic status.

In accelerated stableness survey, lower limit of 3 points including the initial and concluding clip points ( e.g. , 0, 3, 6 months ) from a 6 month survey were analyzed. Accelerated survey conditions comprised of 40A± 2A°C/75A± 5 % RH for 6 months. The assay consequences informations was analyzed by comparing between different commercial trade names and were found to be sensitive to elevated temperatures every bit good as to high comparative humidness.

In my survey, I analyzed that the active ingredient should hold best consequence in ambient clime while in accelerated clime, there were small bit debasement of active drug stuff ( Cholecalciferol ) .

Introduction:

Degradation during storage and transit is of peculiar critical issue in tropical states. Indeed, shelf life ( an termination day of the month ) determined for a temperate clime may be inappropriate in a tropical part even when high criterions of packaging are met.

For this intent, peculiar importance is accorded to ocular review of dose signifiers, since this frequence provides a first critical indicant of debasement which may be due to hapless industry, fiddling etc.

Because the distribution environment is extremely variable, merchandises must be distributed in a mode that ensures the drug merchandise quality will non be adversely affected. The consequence of possible temperature and comparative humidness fluctuations, outside of labelled storage conditions, during transit of drug merchandises, can be evaluated on the footing of the stableness analysis for that drug [ 1, 3 ] .

No pharmaceutical merchandise is stable indefinitely and surely the bulk of drug merchandises are stable merely for a limited clip. The instability may be demonstrated as active drug or excipients debasement. Instability is thermodynamic phenomenon in nature of pharmaceutical preparations.

Vitamin D3 or Cholecalciferol normally known as the “ Sunshine vitamin ” is indispensable for Ca metamorphosis and for bone wellness. The major physiological map of Cholecalciferol is to keep the blood Ca and P degrees within the normal scope, metabolic maps are indispensable for most of the life procedure. Cholecalciferol is synthesized from 7-dehydrocholesterol in tegument by the action of sunshine. Under UV beam between 290-315 nanometer, 7-dehydrocholesterol is converted to previtamins D3. However, it is thermodynamically unstable easy rearrange to more stable signifier, Vitamin D3 [ 4, 6, 10 ] .

Cholecalciferol ( Vitamin D3 ) undergoes degradation reactions at elevated temperatures and high humidness conditions [ 7 ] .Our end in this work was to spread out probe of debasement of assorted Cholecalciferol samples of tablets to a wider scope of conditions than reported antecedently. Degradation of Cholecalciferol ( Vitamin D3 ) tablets was compared to pure Cholecalciferol.

Cholecalciferol is the vitamin that mediates enteric Ca soaking up, bone Ca metamorphosis and really likely, musculus activity, normally acts as a endocrine precursor [ 8 ] .

Structure of Vitamin d:

Cholecalciferol-activated 7-dehydrocholesterol [ 9 ] .

Cholecalciferol is besides called as activated 7-dehydrocholestrol or vitamin D3. Their chemical expression is C27H44O and molecular weight is 384.7. Its runing point is 84A°C to 88A°C.It is white odorless crystals which are affected by air and visible radiation. It should be stored in a cool topographic point in certain glass containers in which the air has been replaced by an inert gas. Cholecalciferol should be protected from light [ 5 ] . It is oxidized and inactivated by moist air within a few yearss [ 8 ] .

ACCELERATED STABILITY STUDY:

Accelerated survey is the survey designed to increase the rate of chemical debasement and/or physical alteration of a drug substance or drug merchandise by utilizing overdone storage conditions with the intent of supervising debasement reactions and foretelling the shelf life under normal storage conditions.

The Stability trial plan comprised of trial points ( 0, 3, 6 months ) at given stableness conditions. 15 battalions of merchandise are required to execute the complete analysis as per the accelerated stableness specifications.

Oxidation is a good known chemical debasement tract for Cholecalciferol. Oxygen, which participates in most oxidization reactions, is abundant in the environment to which Cholecalciferol is exposed, during either processing or long term storage.

Oxidation mechanisms for drug substances ( Cholecalciferol ) depend on the chemical construction of the drug and the presence of reactive O species or their oxidizers.

THE EFFECT OF TEMPERATURE, RELATIVE HUMIDITY AND LIGHT:

Temperature and Relative humidness universally affect the drug molecule but if we protect the drug from visible radiation from the start of fabrication e.g. , As Cholecalciferol ( Raw stuff ) is packed in aluminum container, while during drug fabrication it is protected from visible radiation, so it is non necessary to look into light as critical parametric quantity during ASS of Cholecalciferol.

Evaluation OF STABILITY DATA:

The information may unclutter so small debasement and so small variableness that it is evident from looking at the information that the requested re-test period will be granted. Under these fortunes, it is usually unneeded to travel through the formal statistical analysis ; supplying a justification for the skip should be plenty.

An attack for analyzing the information on a quantitative property that is expected to alter with clip is to find the clip at which the 95 % nonreversible assurance bound for the average curve intersects the credence standard. If analysis indicates that the batch-to-batch variableness is little, it is advantageous to unite the information into one overall estimation.

Equally good as my survey is concerned, I am covering with a category of medical specialty that has one sided critical part for the statistical facets of analysis that lies on the greater side of the normal curve. The value for the under survey curve that get an addition from the criterion ( targeted or nominal value ) set by official books, I find my critical value to the right manus tail of my normal curve.

This can be completed by first using appropriate statistical trials, e.g. , P values observed degree of significance of rejection of more than 0.25 to the coefficient of the arrested development ( we are regressed months with batches, it indicates that there is a 25 % alteration in one variable to other ) and zero clip intercepts for the single batches. If it is non suited to unite informations from several batches, the overall retest period should be based on the minimal clip a batch can be expected to stay within credence standards [ 2 ] .

RESULT AND DISCUSSION:

Three trade names of Cholecalciferol ( Vitamin D3 ) tablets i.e. , ( a ) Qalsan D, ( B ) Calgo and ( degree Celsius ) Osam-D incorporating 125, 125 and 400 IU severally of Cholecalciferol were used in this survey.

Qalsan D tablet in record of assay content had no debasement observed and was stable at temperature 40A±2 oC and Relative humidity75A±5 % while Osam-D and Calgo in record of assay content show small bit debasement at given accelerated stableness survey parametric quantities.

The trade names of Cholecalciferol tablets were found to follow with the Pharmacopoeial demands as shown in supra tabular array as respects to their fluctuation in assay contents.

The check content trials of tablet were carried out by utilizing methyl alcohol as space, formic acid and dinitrophenylhydrazin supply by dependable beginnings at i?¬max 265nm, utilizing Double beam UV Spectrophotometer.

The per centum of Qalsan D tablet samples of Batch 001, 002, 003 were analyzed and checked at month ( 0, 3, 6 ) at specific temperature and comparative humidness.

From assay content behaviour of these Cholecalciferol tablets, it is apparent from above tabular array, ASS information reveals that in first 6 months of Batch 001, consequences decreased from 100.89 % to 100 % . In Batch 002, holding 6 months survey, consequences illustrated downward status from 102.92 % to 101.35 % , while in Batch 003 holding 6 months ASS, consequence move from 100.67 % to 98.43 % .

Similarly both “ P ” values of Qalsan D tablets were placed within the bound i.e. , NMT 0.05, as shown in statistical informations.

The per centum of Calgo tablet samples of Batch 001, 002, 003 were analyzed and checked at month ( 0, 3, 6 ) at specific temperature and comparative humidness.

From assay content behaviour of these Cholecalciferol tablets, it is apparent from above tabular array, ASS information reveals that in first 6 months of Batch 001, consequences decreased from 105.63 % to 98.19 % . In Batch 002, holding 6 months survey, consequences illustrated downward status from 107.79 % to 97.50 % , while in Batch 003 holding 6 months ASS, consequence move from 110.49 % to 104.67 % .

Similarly out of two “ P ” values, one “ P ” value of Calgo tablets was out of the bound while other meets the demand, i.e. , NMT 0.05, as shown in statistical informations.

The per centum of Osam-D tablet samples of Batch 001, 002, 003 were analyzed and checked at month ( 0, 3, 6 ) at specific temperature and comparative humidness.

From assay content behaviour of these Cholecalciferol tablets, it is apparent from above tabular array, ASS information reveals that in first 6 months of Batch 001, consequences decreased from 104.54 % to 96.18 % . In Batch 002, holding 6 months survey, consequences illustrated downward status from 102.69 % to 97.27 % , while in Batch 003 holding 6 months ASS, consequence move from 103.61 % to 96.19 % .

Similarly out of two “ P ” values, one “ P ” value of Osam-D tablets was out of the bound while other meets the demand, i.e. , NMT 0.05, as shown in statistical informations.

CONCLUTION:

From consequence and treatment, the chief decisions of the present probe on the accelerated stability-indicating Non-Pharmacopoeial method for check of different trade names of Cholecalciferol tablet may be summarized as follows:

The assay stableness of the Cholecalciferol tablet was investigated under assorted conditions. Cholecalciferol tablet samples were found to be sensitive to elevated temperatures every bit good as to high comparative humidness. The most stable signifier is obtained in Qalsan D tablet preparations.

The Qalsan D tablet has stable Cholecalciferol molecule for 2 old ages while debasement of Cholecalciferol in Calgo tablet and Osam-D tablet high spots unstability of molecule under emphasis conditions and should be degraded wholly before 2 old ages. The difference in assay contents with the advancement of month and batch can be explained on the footing of oxidative debasement phenomenon. Three trade names of tablets, consequently of grade of oxidative debasement of Cholecalciferol are arranged in following sequences:

Qalsan D a†’ Osam-D a†’ Calgo.

Suggestion:

Some of the most complex tablet preparations include vitamins/multivitamins/minerals. These may be exposed to temperature and comparative humidness during fabrication, storage and disposal doing vitamin interaction and loss of the single vitamins.

In position of the sensitiveness of Cholecalciferol and the influence of factors such as temperature, comparative humidness, presence of other vitamins, in a multivitamin readying, an rating of stableness features of Cholecalciferol highly hard.

This may be used to carry on further systematic surveies on the rating of Cholecalciferol stableness in tablet mixtures.

Designation of the unknown oxidative every bit good as degradative merchandises of Cholecalciferol in tablet.

Development of Stability-determining methods for check of a Cholecalciferol in the presence of its debasement merchandise.

Survey of the relationship of debasement rates with Non-Pharmacopoeial methods applied during analysis of Cholecalciferol tablet.
