Fenoldopam mesylate (Corlopam) is a drug and synthetic benzazepine derivative which acts as a selective D1 receptor partial agonist. Fenoldopam is used as an antihypertensive agent. It was approved by the Food and Drug Administration (FDA) in September 1997. Indications
Fenoldopam is used as an antihypertensive agent postoperatively, and also intravenously (IV) to treat a hypertensive crisis. Since fenoldopam is an intravenous agent with minimal adrenergic effects that improves renal perfusion, in theory it could be beneficial in hypertensive patients with concomitant chronic kidney disease. It can cause reflex tachycardia, but it is dependent on the infusion of the drug. Pharmacology
Fenoldopam causes arterial/arteriolar vasodilation leading to a decrease in blood pressure by activating peripheral D1 receptors. It decreases afterload and also promotes sodium excretion via specific dopamine receptors along the nephron. The renal effect of fenoldopam and dopamine may involve physiological antagonism of the renin-angiotensin system in the kidney. In contrast to dopamine, fenoldopam is a selective D1 receptor agonist with no effect on beta adrenoceptors, although there is evidence that it may have some alpha-1  and alpha-2 adrenoceptor antagonist activity. D1 receptor stimulation activates adenylyl cyclase and raises intracellular cyclic AMP, resulting in vasodilation of most arterial beds, including renal, mesenteric, and coronary arteries. to cause a reduction in systemic vascular resistance. Fenoldopam has a rapid onset of action (4 minutes) and short duration of action (< 10 minutes) and a linear dose–response relationship at usual clinical doses. Side effects
Adverse effects include headache, flushing, nausea, hypotension, reflex tachycardia, and increased intraocular pressure.
Vaginal trauma from consensual and non-consensual intercourse
Vaginal trauma is possible during and after consensual and non-consensual intercourse so it is difficult to determine the circumstances in which the trauma occurs only based on a physical examination. It can be difficult to differentiate between injuries from consensual sex and injuries from sexual assault in adolescents. Women are three times more likely to have vaginal injuries and intercourse-related injuries from a forced assault than from a consensual sexual experience. Vaginal lacerations that happen during consensual or non consensual intercourse might need surgery, but victims of a forced assault will need additional services such as police intervention and trauma counseling. There is little research on minor injuries in adult, pre-menopausal women, adolescent girls, and post-menopausal women that do not require surgery or treatment. Why does vaginal trauma occur? There are factors that can predispose women to vaginal injury during consensual sex. These things include: first sexual experience, pregnancy, vigorous penetration, vaginal atrophy and spasm, previous operation or radiation therapy, disproportionate genitalia, penile ornamentation, and congenital anomalies. During vaginal intercourse in the missionary position with legs tilted all the way back, the penis reaches its deepest penetration and the extreme rotation of the uterus leads to hyper distention of the vaginal wall, which in some cases can cause it to rupture. This position is the most likely position for vaginal laceration. The vaginal wall on the right side is the most commonly torn sight in this position. Vaginal lengthening and lubrication usually occurs naturally in a consensual sexual situation.
