We have to use 0.9% NaCl for adjustment of tonicity. But for calculation purpose we should compare it with 1% as the freezing point depression of the drug is given in terms of 1% solution.
For cryscopic method, freezing point depression of the drug is required. If it is not given, then we can try to adjust the tonicity by other methods like sodium chloride equivalent method and sprowls method.
The formula given there is exactly correct and it is a simple trick for easy calculation. But within the video, 0.52-0.17 should have value of 0.35 which misplaced with 0.37. So if we put 0.35 there, both direct method and simple method will give 1.21 as answer. Thank you very much for notifying this correction and we will update it in description box. Thank you.
Great lecture..
Thank you sir..
How 0.17 I don’t know how you calculate it
Please make video on class 2 method
You made it too easy🔥
thank you! I finally understand this topic
Glad it was helpful! Thanks for watching.
Really helpful formula. what if there are two drugs, how do we apply to this formula?
Thank you soo much sir ❤❤❤
Tnq
Nice presentation sir please made more video related to physical pharmaceutics
Thank you sir🎉
Sir, by using simple formula the answer wil be 0.137????
Excellent👌🏽
why did u use 1% nacl and not 0.9% ? is it up to whats asked of us to use ? it could be either ?

Sir, your calculation for FDP require to produced NaCI should be 0.35 right? Because 0.52-0.17=0.35..Sorry if i am wrong😅
Thanks💗
Omg thanku somuch
0.52-0.17=0.35🙏5:14
Really very easy to follow
Glad to hear that. Thanks for watching
Please provide tricks for white Vincent and sprowls method also sir
Great ❤️
Thank u so much
What if freezing point of drug is not given in data
For cryscopic method, freezing point depression of the drug is required. If it is not given, then we can try to adjust the tonicity by other methods like sodium chloride equivalent method and sprowls method.
the formula answer is not 1.28 is 1.21 ! so the formula is wrong
