Phenylephrine
Phenylephrine is a medication primarily used as a decongestant, to dilate the pupil, to increase blood pressure, and to relieve hemorrhoids. In the United States, it was previously used orally as an over-the-counter decongestant to relieve nasal congestion due to sinusitis, but this use was discontinued in 2007. As of 2022, its use as a nasal decongestant in other applications still persists. Phenylephrine can be taken by mouth, as a nasal spray, given by injection into a vein or muscle, or applied to the skin. Common side effects when taken by mouth or injected include nausea, vomiting, headache, and anxiety. Use on hemorrhoids is generally well tolerated. Severe side effects may include a slow heart rate, intestinal ischemia, chest pain, kidney failure, and tissue death at the site of injection. It is unclear if use during pregnancy or breastfeeding is safe. Phenylephrine is a selective α1-adrenergic receptor agonist which results in the constriction of both arteries and ...

Oxymetazoline
Oxymetazoline, sold under the brand name Afrin among others, is a topical decongestant and vasoconstrictor medication. It is available over-the-counter as a nasal spray to treat nasal congestion and nosebleeds, as eyedrops to treat eye redness due to minor irritation, and (in the United States) as a prescription topical cream to treat persistent facial redness due to rosacea in adults. Its effects begin within minutes and last for up to 6 hours. Intranasal use for longer than three days may cause congestion to recur or worsen, resulting in physical dependence.

Octopamine (drug)
Octopamine (molecular formula C8H11NO2; also known as OA, and also norsynephrine, ''para''-octopamine and others) is an organic chemical closely related to norepinephrine, and synthesized biologically by a homologous pathway. Octopamine is often considered the major "fight-or-flight" neurohormone of invertebrates. Its name is derived from the fact that it was first identified in the salivary glands of the octopus. In many types of invertebrates octopamine is an important neurotransmitter and hormone. In protostomes — arthropods, molluscs, and several types of worms — it substitutes for norephinephrine and performs functions apparently similar to those of norepinephrine in mammals, functions that have been described as mobilizing the body and nervous system for action. In mammals octopamine is found only in trace amounts, and no biological function has been solidly established for it. It is also found naturally in numerous plants, including bitter orange. Octopamine has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norepinephrine
Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter. The name "noradrenaline" (from Latin '' ad'', "near", and '' ren'', "kidney") is more commonly used in the United Kingdom, whereas "norepinephrine" (from Ancient Greek ἐπῐ́ (''epí''), "upon", and νεφρός (''nephrós''), "kidney") is usually preferred in the United States. "Norepinephrine" is also the international nonproprietary name given to the drug. Regardless of which name is used for the substance itself, parts of the body that produce or are affected by it are referred to as noradrenergic. The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the ...

Naphazoline
Naphazoline is a medicine used as a decongestant, and a vasoconstrictor added to eye drops to relieve red eye. It has a rapid action in reducing swelling when applied to mucous membranes. It is a sympathomimetic agent with marked alpha adrenergic activity that acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It was patented in 1934 and came into medical use in 1942. Medical uses Nasal administration Nasal decongestant. Ophthalmic drug administration Eye drops (brand names Clear Eyes, and Cleari) narrowing swollen blood vessels ( ophthalmic arteries, and ophthalmic veins) to relieve red eye. Temporary red eye can safely be treated when the cause of the redness is established (eg cannabis induces corneal vasodilation) nsufficient Bibliography However, continuous use is not recommended without knowing an underlying condition. Side effects A few warnings and contraindications that apply to all naphazolin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midodrine
Midodrine is a vasopressor/antihypotensive agent (it raises the blood pressure). Midodrine was approved in the United States by the Food and Drug Administration (FDA) in 1996 for the treatment of dysautonomia and orthostatic hypotension. In August 2010, the FDA proposed withdrawing this approval because the manufacturer, Shire plc, failed to complete required studies after the medicine reached the market. In September 2010, the FDA reversed its decision to remove midodrine from the market and allowed it to remain available to patients while Shire plc collected further data regarding the efficacy and safety of the drug. Shire announced on September 22, 2011, that it was withdrawing completely from supplying midodrine and leaving it to several generics to supply the drug. Medical uses Midodrine is indicated for the treatment of symptomatic orthostatic hypotension. It can reduce dizziness and faints by about a third, but can be limited by troublesome goose bumps, skin itch, gas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methyldopa
Methyldopa, sold under the brand name Aldomet among others, is a medication used for high blood pressure. It is one of the preferred treatments for high blood pressure in pregnancy. For other types of high blood pressure including hypertensive emergency, very high blood pressure resulting in symptoms other medications are typically preferred. It can be given Oral administration, by mouth or intravenous, injection into a vein. Onset of effects is around 5 hours and they last about a day. Common side effects include sleepiness. More severe side effects include hemolysis, red blood cell breakdown, liver problems, and allergic reactions. Methyldopa is in the alpha-2 adrenergic receptor agonist family of medication. It works by stimulating the brain to decrease the activity of the sympathetic nervous system. Methyldopa was discovered in 1960. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essential Medicines. Medical uses Methyldopa is us ...

Metaraminol
Metaraminol, previously sold under the brand name Aramine among others and also known as metaradrine, is a stereoisomer of ''meta''-hydroxynorephedrine (3,β-dihydroxyamphetamine), is a potent sympathomimetic amine used in the prevention and treatment of hypotension, particularly as a complication of anesthesia. It is an α1-adrenergic receptor agonist with some β effect. It is currently sold in its generic form by Slayback Pharma. Pharmacology and use as a vasopressor Metaraminol is given intravenously as either a bolus (often 0.5-1mg doses) or as an infusion, usually via peripheral intravenous access. Metaraminol is commonly available as 10mg in 1mL, that requires dilution prior to administration (often made up to a 0.5mg/mL solution), however pre-prepared syringes of metaraminol for bolus use for hypotension are also commonly available. Pharmacodynamics The dominant mechanism for the vasopressor action of metaraminol is indirect, with metaraminol displacing noradrena ...
