xanthine has been researched along with Hypotension in 5 studies
7H-xanthine : An oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-7 is protonated.
9H-xanthine : An oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-9 is protonated.
Hypotension: Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.

| "First, this investigation showed that plasma levels of inosine, hypoxanthine, and xanthine, which are metabolites of adenosine, rose sharply when blood pressure dropped suddenly along with symptoms during a hemodialysis session (sudden hypotension), but not when it decreased gradually with eventual symptoms (gradual hypotension)." | 9.07 | Role of adenosine in dialysis-induced hypotension. ( Inoue, I; Maeda, K; Miwa, M; Morita, H; Nakai, S; Odani, H; Shinzato, T, 1994) |

| "Values of guanosine, inosine, hypoxanthine, xanthine and uridine were significantly higher, while ECBA was significantly lower after hemorrhagic hypotension than control values." | 3.73 | Purine and pyrimidine metabolism and electrocortical brain activity during hypotension in near-term lambs.

| "Cerebral blood flow (CBF, by laser Doppler flowmetry) and extracellular cortical concentrations (by microdialysis) of adenosine, inosine, xanthine, hypoxanthine, and lactate were measured together with somatosensory evoked potentials (SEP) in chloralose-anaesthetized spontaneously hypertensive rats (SHR) during relative cerebral ischemia induced by hypotensive hemorrhage." | 3.67 | Relative cerebral ischemia in SHR due to hypotensive hemorrhage: cerebral function, blood flow and extracellular levels of lactate and purine catabolites. ( Carlsson, S; Hagberg, H; Sandberg, M; Skarphedinsson, JO; Thorén, P, 1989) |
| " This study tests the hypothesis that there is a direct relationship between periods of hypotension and body fluid uric acid and oxypurine levels in 19 prospectively studied patients." | 3.67 | Increased body fluid purine levels during hypotensive events. Evidence for ATP degradation. ( Fox, IH; Woolliscroft, JO, 1986) |
