Ph of drugs
WebThe degree of ionisation of weak monobasic acidic drugs at different pH values may be calculated using the Henderson-Hasselbalch equation: Non-ionised form p^ = pH + log [ … WebThe intraluminal pH is rapidly changed from highly acid in the stomach to about pH 6 in the duodenum. The pH gradually increases in the small intestine from pH 6 to about pH 7.4 in the terminal ileum. The pH drops to 5.7 in the caecum, but again gradually increases, reaching pH 6.7 in the rectum.

WebThe pH for normal urine fluctuates throughout the day but usually is in the range of 4.5 to 8.0. Specimen contamination should be suspected if the pH level is less than 3 or greater than 11 or if the specific gravity is less than 1.002 or greater than 1.020. 16 Creatinine concentrations in normal human urine should be greater than 20 mg/dL.
