Buffers are integral to maintaining proper function and stability in both pharmaceuticals and biological systems. Pharmaceutical Buffers Purpose: Stability: Many drugs are pH-sensitive; buffers maintain pH to prevent degradation. Solubility: The solubility of active ingredients can depend on pH. Efficacy and Safety: Proper pH ensures optimal drug action and minimizes irritation. Applications: Injectable Preparations: Must … Read more
Definition of Buffer Capacity Buffer Capacity (β): A quantitative measure of a buffer’s ability to resist pH changes. Mathematical Expression: $\beta = \frac{\Delta B}{\Delta{pH}}$ $\Delta \mathrm{pH}$ = amount (in moles per liter) of strong acid or base added. $\Delta B$ = change in pH resulting from the addition. Factors Affecting Buffer Capacities Concentration of Buffer … Read more
Buffer Equation, or Henderson-Hasselbalch equation, calculates the pH of a buffer solution based on the concentrations of its components. For Acidic Buffers Equation: $\mathrm{pH} = \mathrm{p}K_a + \log_{10} \left( \frac{[{A^-}]}{[{HA}]} \right)$ where: is the negative logarithm of the acid dissociation constant. is the concentration of the conjugate base. is the concentration of the weak … Read more
Once the isotonicity of a solution is determined, adjustments may be necessary. Methods are categorized into Class I and Class II. 1.Class I Methods of Adjusting Isotonicity Definition Methods that involve adding solutes to adjust the isotonicity of a solution without changing its volume significantly. Techniques Sodium Chloride Equivalent Method Concept: Calculates the amount of … Read more
Methods to Determine Isotonicity is Ensuring a solution is isotonic is vital for safety and efficacy. Two primary methods are employed to assess isotonicity: 1. Cryoscopic Methods to Determine Isotonicity The cryoscopic method evaluates a solution’s freezing point depression to determine its osmotic pressure. Principle: The presence of solutes lowers the freezing point of a … Read more
