Stability Testing for Pharmaceuticals. Stability testing is utilized to determine if the quality of a drug substance or drug product is altered over time by various environmental factors, such as light, temperature, and humidity. A drug substance, often referred to as an Active Pharmaceutical Ingredient (API), is defined as the. Stability testing examines the quality and potency of drug at suitable time intervals under the influence of environmental factors such as temperature, light, oxygen, moisture, other ingredient or excipient in the dosage form, particle size of drug, microbial contamination, trace metal contamination, leaching from the container However, stability studies are also essential during the pharmaceutical development of a new drug, to guarantee its proper handling and formulation, and to avoid mistakes in the evaluation, both in vitro and in vivo, of the activity or bioavailability due to dosing problems or drug instability in physiological conditions • Reduction of package screening studies prior to registration stability • Flexibility for post-approval changes to stability commitments • Can be used specifically in early in development to • compare prototype formulations • identify stability issues (i.e. utilized as part of Genotoxic Impurities (GTI) contro It has become mandatory to perform stability studies of new drug moiety before filing in registration dossier. The stability studies include long term studies (12 months) and accelerated stability studies (6 months). But intermediate studies (6 months) can be performed at conditions milder than that used in accelerated studies

Regulatory Requirements Stability testing is required by a number of regulatory agencies. The ICH harmonized tripartite guidelines on stability testing are the Q1A-Q1E documents (Q1F was withdrawn in 2006) and ICH Q5C, which is specifically for biologics (3, 5-9).Q1A is the parent guideline for stability testing of all pharmaceuticals Studies designed to increase the rate of chemical degradation and physical change of an API or FPP by using exaggerated storage conditions as part of the stability testing programme.

The hydrolysis kinetics of hydralazine hydrochloride was studied at pH 1 to 12 at 35°, 50°, and 70° C. The hydrolysis takes place by water attack on the dicationic and the cationic forms of the drug. In addition there is hydroxyl attack on the cationic and the neutral forms of the drug. The drug is not subject to attack by acetate and carbonate buffers, but its decomposition is catalyzed by.

  1. g the drug should get its full dose and not go under medication.[6] Decomposition or instability of API active pharmaceutical ingredient in the drug may lead to formation of toxic products that are harmful for human health..
  2. For these pharmaceutical products the stability studies may be restricted to dosage forms because for established drug substances, literature data is available on the decomposition process and degradability of the active substances along with adequate analytical methods. Thus the actual stability of these dosage forms depends on the formulation.

Drug substance stability studies are then conducted to define stability under long-term and accelerated storage conditions. In the next phase of the development plan, the drug substance is formulated into a drug product and compatibility of the drug substance with excipients and container parts is then tested Stability studies performed by the pharmaceutical industry are only designed to fulfill licensing requirements.

An approach to analyzing and interpreting kinetic data from stability studies using factorial designs is presented. This may be useful for screening purposes or as an aid in identifying significant effects in complex systems. A typical 2 n factorial experiment is discussed, and methods of variance estimation and statistical testing are. indicators of product stability. Studies of the exposure of the drug substance or drug product to extreme conditions may help to reveal patterns of degradation; if so, such changes should be monitored under proposed storage conditions. Conditions should be carefully selected on a case-by-case basis.11 Likewise for new drug substances an matrixing to stability studies conducted in accordance with principles outlined in the ICH Q1A(R) Harmonised Tripartite guideline on Stability Testing of New Drug Substances and Products (hereafter referred to as the parent guideline). 1.2 Background The parent guideline notes that the use of matrixing and bracketing can be applied, if justified Study of drug-excipient compatibility is an important stage in pre-formulation studies during the development of pharmaceuticals. Indeed, potential physical and chemical interactions between drug and excipients can affect the chemical nature, stability, and bioavailability of a drug and thus its effectiveness [1-6].In the literature, two types of chemical incompatibilities have been. Photostability studies of drugs and drug products are an integral part of the product development process in the pharmaceutical industry. These studies are carried out to ensure quality, efficacy, and safety of the formulated products during manufacture, storage, and use. This review deals with the concept of photostability and related aspects and the literature available in the field

ICH Stability Studies: Storage and Testing Services Gathering pharmaceutical stability testing data on drug products or drug substances to determine an overall stability profile is a necessary step in the drug approval process. Guidelines for conducting stability studies are described in ICH Q1A(R2) and the ICH stability guidance has been adopted by the European Medicines [ As the stability climatic zones of the world are different but for different climatic zone study also change. Different stability condition and different climatic zones are depends on temperature and humidity of the region. Stability testing is a study to check the quality of drug throughout life of drug product. Classification of Countries. There were several limitations in performing this review. The definition of drug stability varied greatly between studies. 2, 29 In the reports reviewed, investigators suggested the drug to be stable when anywhere from no drug loss to <10% drug degradation occurred by a specified time point. A stability cut-off value of >95% of the initial drug. We report on the stability assessment of a recombinant human epidermal growth factor (rhEGF) freeze-dried formulation for wound healing by intra-lesional injections. The suitability of packaging material for the light protection of finished dried powder was evaluated after stressed exposure conditions. Degradation kinetics of powder for injection was investigated at concentrations of 25-250. E.g. radiopharmaceutical products. Since the evaluation of the stability of drug is highly specialized and esoteric nature. Drug stability concerns about drug product safety, efficacy, and quality, found it to appropriate.
