Pharmacokinetics study of chitosan-coated liposomes containing sumatriptan in the treatment of migraine.

Background: Sumatriptan is a routine medication in the treatment of migraine and cluster headache that is generally given by oral or parental routes. However, a substantial proportion of patients suffer severe side effects. The aim of this study was to investigate the physicochemical characterization and pharmacokinetic parameters of a novel delivery system for sumatriptan succinate (SS) using nanoliposomes (NLs) coated by chitosan (CCLs) to optimize the formulations to enhance its bioavailability.

Harnessing Intranasal Delivery Systems of Sumatriptan for the Treatment of Migraine.

Sumatriptan (ST) is a commonly prescribed drug for treating migraine. The efficiency of several routes of ST administration has been investigated. Recently, the intranasal route with different delivery systems has gained interest owing to its fast-acting and effectiveness.

Simvastatin prevents morphine antinociceptive tolerance and withdrawal symptoms through antioxidative effect and nitric oxide pathway in mice.

Oxidative stress and the nitric oxide (NO) pathway are involved in the development of opioid analgesic tolerance and dependence. Simvastatin modulates NO and oxidative stress, so the present study aimed to investigate its effect on the development and expression of morphine analgesic tolerance and withdrawal signs in mice. Morphine tolerance and dependence were induced by twice daily morphine injection (10 mg/kg, s.

Niosome-loaded antifungal drugs as an effective nanocarrier system: A mini review.

Skin is an important organ of the body due to offering an accessible and convenient site for drug administration. One of the disadvantages of transdermal drug delivery is the low penetration rate of drugs through the skin. Over the past decades, nanoparticles have been used as drug delivery systems to increase therapeutic effects or reduce toxicity.

Prospective evaluation of oral gastrografin(®) in the management of postoperative adhesive small bowel obstruction.

Oral Gastrografin®, a hyperosmolar water-soluble contrast medium, may have a therapeutic effect in adhesive small bowel obstruction. However, findings are still conflicting, as some authors did not find a therapeutic advantage. So, this prospective, randomized, and clinical trial study was designed to determine the value of Gastrografin in adhesive small bowel obstruction.

Morphine-induced anxiolytic-like effect in morphine-sensitized mice: involvement of ventral hippocampal nicotinic acetylcholine receptors.

In the present study, the effects of repeated intra-ventral hippocampal (intra-VH) microinjections of nicotinic acetylcholine receptor agonist or antagonist on morphine-induced anxiolytic-like behavior were investigated in morphine-sensitized mice using elevated plus-maze. Intraperitoneal (i.p.
