What are the quality Norms and Protocols followed for analysis?
Analysis is done as per both National and International Standards with following major protocols,
» Indian Pharmacopoeia
» United States Pharmacopoeia
» British Pharmacopoeia
» British Herbal Pharmacopoeia
» Ayurvedic Pharmacopoeia
» Unani Pharmacopoeia
» European Pharmacopoeia
» Martindales Extra Pharmacopoeia
» Any other protocol
In addition to this, products not listed in the pharmacopoeia are also analysed by the methods developed by scientists of SRI.

What are the general methods followed for various drugs and pharmaceutical products ?
The general methods for various drugs and pharmaceutical products are as follows:
» Physical
» Chemical
» Instrumental
» Microbiological
» Pharmacological

What are the test parameters evaluated by using different methods ?
In order to ensure the right quality of the products, besides testing for the active ingredients, it is also necessary to test several other parameters. For each parameter the protocols/validated methods are used. Following list gives the details of the parameters other than purity and their methods.

SRI has all the facilities to take up the analysis of the above test parameters in different products as mentioned below.

Parameters other than purity are analysed using different methods :

What are the facilitites at SRI ?
SRI is equipped with all facilities and has an animal house to take up the relevant test parameters for quality evaluation of different health care products. The details of the instruments are given in the list enclosed. The experts can not only develop validated methods for raw materials impurities and finished products but can also provide consultancy in the following areas:
» Extraction of Herbal Products.
» Process Improvements
» Product Differentiation.

Shelf Life / Stability Studies of Drugs and Pharmaceutical Products

What is Shelf life in case of Health Care Products ?
Shelf-life refers to the period from initial preparation and packaging during which the drug dosage form continues to remain within its physical, chemical, therapeutic and toxicological specifications at specified storage conditions.
The product must retain 90% of the labeled claim at the end of shelf-life.

What does stability mean for drugs and pharmaceuticals ?
The stability of the product is its ability to resist deterioration. It is always expressed in terms of shelf life.

As per USP there are five types of stability studies :
» Chemical
» Physical
» Microbiological
» Therapeutic
» Toxicological

What are the factors affecting Stability ?
The various factors affecting pesticides stability are :

» Environmental factors
» Temperature
» Light
» Air
» Oxygen
» Moisture
» Carbondioxide
» Other ingredients or excipients in the dosage form
» Particle size of drug
» pH of the vehicle
» Microbial contamination
» Tracemetal Contamination
» Leaching from containers

When do we need stability testing ?
How are the stability tests conducted ?
» Studies are conducted at
» Accelerated conditions
» Controlled room temperature conditions
» Product samples are analyzed at various intervals by validated analytical methods

Facilities at SRI for stability studies:-
SRI has the complete arrangement to take up the studies for shelf life / stability as per the various laid down protocols. SRI undertakes stability studies for all dosage forms.

Third Party Inspection
SRI undertakes third party inspection and testing of pharmaceutical supplies to various State Government Health Departments. The team of experts can undertake the inspection of different drugs and pharmaceutical.products.
