ACE inhibitors, such as captopril and enalaprilat, the active metabolite of enalapril, occupy the enzyme as false substrates. Affinity significantly influences efficacy and rate of elimination. Enalaprilat has a stronger and longerlasting effect than does captopril.
Work-up for lower abdominal pain begins with resuscitation and exclusion of critical diagnoses: AAA (Abdominal Aortic Aneurysm); Mesenteric Ischemia; Perforation; SBO (small bowel obstruction); ectopic pregnancy

Begin work-up by ruling out emergent/urgent conditions and evaluating/charting the absence of red flags that can signal the presence of an emergent condition. Then consider other visceral causes of low back pain. If no red flags are present and patient does not need further work-up, then the likely default diagnosis is benign mechanical (lumbar strain) Low Back Pain
Risk factors for Aortic Aneurysm: smoking, male sex, age, pre-existing atherosclerosis, obesity, Hyperlipidemia, HTN (Hypertension), Family History
The distribution of blood within the circulation is a function of vascular caliber. Venous tone regulates the volume of blood returned to the heart, hence, stroke volume and cardiac output.…
