There is an epinephrine metered-dose inhaler sold over the counter in the United States to relieve bronchial asthma. [67] [68] It was introduced in 1963 by Armstrong Pharmaceuticals. [69] A common concentration for epinephrine is 2.25% w/v epinephrine in solution, which contains 22.5 mg/mL, while a 1% solution is typically used for aerosolization.
Angioedema can be due to antibody formation against C1INH; this is an autoimmune disorder. This acquired angioedema is associated with the development of lymphoma. Consumption of foods that are themselves vasodilators, such as alcoholic beverages or cinnamon, can increase the probability of an angioedema episode in susceptible patients. If the ...
Drug-induced angioedema is a known complication of the use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin II antagonists (ARBs), and Angiotensin-Neprilysin Inhibitor LCZ969. [ 1 ] : 120 The angioedema appears to be dose dependent as it may resolve with decreased dose.
Adrenergic blocking agents are a class of drugs that exhibit its pharmacological action through inhibiting the action of the sympathetic nervous system [1] in the body. The sympathetic nervous system(SNS) is an autonomic nervous system that we cannot control by will.
Pheochromocytoma patients often have plasma adrenaline levels of 1000–10,000 ng/L. Parenteral administration of adrenaline to acute-care cardiac patients can produce plasma concentrations of 10,000 to 100,000 ng/L. [82] [83]
The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine), which function as both neurotransmitters and hormones. Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other ...
With regards to the mutations in the SERPING1 gene that is seen in hereditary angioedema types 1 and 2 (hereditary angioedema with C1 inhibitor deficiency), 75% of the cases are due to an autosomal dominant inheritance of a mutated gene and 25% of cases are due to de novo mutations of the egg or sperm, or early in embryological development.

Tranexamic acid is used in dentistry in the form of a 5% mouth rinse after extractions or surgery in patients with prolonged bleeding time; e.g., from acquired or inherited disorders. [37] In China, tranexamic acid is allowed in over-the-counter toothpaste, with six products using the drug.
