| Description | Quazolast (RHC 3988) is a potent mediator release inhibitor used as a control against ragweed antigenic nasal challenge and demonstrates superiority over placebo in preventing nasal congestion and nasal itching following such challenges. |
| In vivo | Quazolast (400 mg ; orally ; RW allergy ; 23 subjects) had significantly lower (P less than .05) mean percent decreases in nasal flow rate at 1350 and 2700 PNU for subjects. Nasal itchiness scores were significantly lower (P less than .05) during Quazolast treatment than at placebo at 1000, 1350, and 2700 PNU.[1] |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
