Correlation between Ph Pka and absorption of drug?
pKa of a drug is the pH at which the drug is 50% ionized and 50% non-ionized. This can affect drug absorption as the ionized form may have different solubility and permeability properties compared to the non-ionized form. Understanding the pKa of a drug can help predict its behavior in different pH environments and optimize absorption.
How do you find the pka value of a drug?
The pKa value of a drug can be found using laboratory techniques such as potentiometric titration or chemical software. These methods involve measuring the pH at which the drug molecule is half ionized and half unionized. The pKa value indicates the drug's acidity or basicity and helps predict its behavior in biological systems.
How do you know a drug is acidic or basic from pka value?
To be honest, sometimes it can be extremely difficult to choose which equation you should use depending on whether the solution is basic or acidic. But what I do know, is that when the pka is small then the solution is acidic, and when the pka is large then the solution is basic. "A weak acid has a pKa value in the approximate range −2 to 12 in water. Acids with a pKa value of less than about −2 are said to be strong acids. " this being said, its hard to distinguish whether a solution is acidic or basic since they both have such a wide range of pka values. but if you want just a general guideline then i would stick with the rule "high pka=basic, low pka=acidic
