Several formulation variables were studied, such as the quantity of the drug, the type of non-ionic surfactant, the amount of the surfactant, the amount of cholesterol, the effect of ultrasonic sonication, and the time of sonication. The best niosomal formula was incorporated into a gel base, then evaluated and studied for its ex-vivo skin permeability, skin sensitivity test, and pharmacological effect on rats, in addition to studying the effect of storage conditions at three different temperatures.\u00a0The results proved that the gel containing niosomes of tolmetin showed improved specifications, high skin permeability, and no skin sensitivity, in addition to being stable under storage conditions. Therefore, niosomes could be one of the most promising delivery systems for tolmetin, with improved penetration and sustained delivery within 24 hours.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1066 size-full\" src=\"https:\/\/en.copharm.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/80\/2022\/11\/3-4.jpg\" alt=\"\" width=\"985\" height=\"604\" srcset=\"https:\/\/en.copharm.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/80\/2022\/11\/3-4.jpg 985w, https:\/\/en.copharm.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/80\/2022\/11\/3-4-300x184.jpg 300w, https:\/\/en.copharm.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/80\/2022\/11\/3-4-768x471.jpg 768w, https:\/\/en.copharm.uobaghdad.edu.iq\/wp-content\/uploads\/sites\/80\/2022\/11\/3-4-600x368.jpg 600w\" sizes=\"auto, (max-width: 985px) 100vw, 985px\" \/><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The College of Pharmacy discussed the Ph.D. Dissertation tagged \u201cFormulation, Characterization, and Ex-Vivo Permeation Study of Tolmetin as Transdermal Niosomal &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.copharm.uobaghdad.edu.iq\/?p=1065\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":9,"featured_media":1066,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[3,7],"tags":[],"class_list":["post-1065","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-latest-news","category-dissuasion"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
