Fluticasone propionate, sold under the brand names Flovent and Flonase among others, is a steroid medication. When inhaled it is used for the long term management of asthma and COPD. In the nose it is used for hay fever and nasal polyps. It can also be used for mouth ulcers.Common side effects when inhaled include upper respiratory tract infections, sinusitis, thrush, and cough. Common side effects when used in the nose include nosebleeding and sore throat. It works by decreasing inflammation.Fluticasone propionate was patented in 1980, and approved for medical use in 1990. It is available as a generic medication. In 2020, fluticasone was the 23rd most commonly prescribed medication in the United States, with more than 24 million prescriptions. Medical uses
Fluticasone propionate is used by powder or aerosol inhalation for the prophylaxis of asthma. The nasal spray is used for prevention and treatment of allergic rhinitis. Nasal drops are used in the treatment of nasal polyps. The nasal spray can also be used in the mouth for mouth ulcers.Fluticasone propionate in a topical form can be used to treat skin conditions such as eczema, psoriasis, and rashes. Adverse effects
If taken correctly, the nasal spray and oral inhaler formulation have fewer corticosteroid side effects than the tablet formulation because they limit systemic (blood) absorption. However, systemic absorption is not negligible even with correct administration. Using the spray or inhaler at higher than recommended doses or with other corticosteroids can increase the risk for serious, systemic corticosteroid induced side effects.
However, this does not mean someone with pure alexia is incapable of comprehending speech—merely that there is no connection between their working visual cortex and language areas—as is demonstrated by the fact that pure alexics can still write, speak, and even transcribe letters without understanding their meaning. Lesions to the fusiform gyrus often result in prosopagnosia, the inability to distinguish faces and other complex objects from each other. Lesions in the amygdala would eliminate the enhanced activation seen in occipital and fusiform visual areas in response to fear with the area intact. Amygdala lesions change the functional pattern of activation to emotional stimuli in regions that are distant from the amygdala.Other lesions to the visual cortex have different effects depending on the location of the damage. Lesions to V1, for example, can cause blindsight in different areas of the brain depending on the size of the lesion and location relative to the calcarine fissure. Lesions to V4 can cause color-blindness, and bilateral lesions to MT/V5 can cause the loss of the ability to perceive motion. Lesions to the parietal lobes may result in agnosia, an inability to recognize complex objects, smells, or shapes, or amorphosynthesis, a loss of perception on the opposite side of the body. Causes
Head injuries can be caused by a large variety of reasons. All of these causes can be put into two categories used to classify head injuries; those that occur from impact (blows) and those that occur from shaking.
