Factors affecting Drug Stability(Cont.) 2 0 obj Show abstract. Although chemical degradation ordinarily cannot be detected by the pharmacist, excessive chemical degradation sometimes is accompanied by observable physical changes. Accessibility In addition, some physical changes not necessarily related to chemical potency, such as change in color and odor, formation of a precipitate, or clouding of solution, may serve to alert the pharmacist to the possibility of a stability problem. This only tells that the complex [Fe(CN)6]3- is extremely stable. Gravity and atmospheric pressure.

However, other excipients, such as glycerin, sorbitol, propylene glycol, flavoring agents, preservatives, and syrups, may be included as well. log . Physical, Chemical, Dietary and Dosage form factors. stream The major dosage form factors that influence drug stability include particle size (especially in emulsions and suspensions), pH, solvent system composition (i.e., percentage of free water and overall polarity), compatibility of anions and cations, solution ionic strength, primary container, specific chemical additives, and molecular binding and diffusion of drugs and excipients. Main factors that affect protein stability include: 1. the term "frequency stability" is used to define the ability of the oscillator to maintain a single fixed frequency as long as possible over a time interval. The influential factors of the slope stability coefficient are different in different stages. The major chemical accelerators or catalysts of hydrolysis are adverse pH and specific chemicals (e.g., dextrose and copper in the case of ampicillin hydrolysis). -+ K~`6w9lVe9eJ',tQVKC"DP5]3=\p7$F7C3{rqy5kz]qV EKTqk..p- I4-BHK]CI`UMxMOGvorp7#Rk,=|Vt!Gno#q9i+.qTF|*bbt'6Krem]. j^oInr[J _;`&fJ;LlDz=.$\, 3 factors 1) type of bone 2) position and strength of ligaments 3) contraction of muscle How does government stability affect a business?
