The conditions can be harsh for API (e.g. The hygroscopic character of a pharmaceutical material is known to influence the behavior of the material during various stages of pharmaceutical process, manufacturing, packing, storage, and transport. Stability studies for pharmaceutical drug . Physiological processes affect the performance (absorption, metabolism, elimination, permeation, solubility, and bioavailability) of the administered drug product by any direct or indirect means. Drug product intended for clinical use after IND approval must be stability tested before IND submission, with preferably 3-6 months' data minimum at submission time. It is not unusual for the storage to experience uncontrolled situations where temperature deviates from the specified values and for the transport to not follow the forecasted routes . In this review paper, we provide an overview of the factors that can cause high gastric pH in human, discuss clinical and preclinical pharmacokinetic data for weak bases under conditions of normal and high gastric pH, and give examples of formulation strategies to minimize or mitigate the reduced absorption of weakly basic drugs under high gastric pH conditions.

The difference between the rate constants at 45 and 25°C becomes about eight times at pH 5 [13]. EFFECT OF PRODUCT pH: Activity of weekly acidic preservatives is associated with unionized molecules so they work best when ionization is low Benzoic and sorbic acids have limited preservative usefulness Above pH 5 Quaternary ammonium and chlorhexidine probably are effective in products of neutral pH. Functional film coats can also be used as a part of the product's stabilisation strategy and to modify or delay drug release. The drug and pharmaceutical materials must be compatible with one another to produce a drug product that is stable, effi cacious, attrac-tive, easy to administer, and safe. pH can affect the rate of growth of microbes, the interaction of the preservative with cell wall components and the MIC (minimum inhibitory concentration) of many preservatives [11,12]. The ultimate goal of every pharmaceutical product is to achieve the required bioavailability to get desired clinical effect. tion and pH is the resulting pH change.The .

Pharmaceutical manufacturers are accountable for delivering medicinal products with the right quality attributes to patients. . product. A Drug in the non-ionized form is more permeable than in its ionized form. In this science article, Timothy J. Snape, Alison M. Astles and Janice Davies discuss the chemical basis for the stability of certain functional groups within drug molecules against hydrolytic degradation and consider the methods used to maximise their stability on storage. The appropriate Non-clinical/Clinical evaluation division should be contacted for guidance in this regard. The usefulness of sodium benzoate as apreservative is limited by its effectiveness over a narrow pH range. Accessibility The effect of sunlight (exposure or protection . Therefore, the use of skin cleansing agents with a pH of about 5.5 may be of relevance in the prevention and treatment of those skin diseases. The containers may be made of glass, plastic, matel or paper. Since such reduction in exposure can lead to significant loss of efficacy, it is imperative to (1) understand the behavior of the compound as a function of stomach pH to inform of any risk of bioavailability loss in clinical studies and (2) develop a robust formulation which can provide adequate exposure in achlorhydric patients.
