Flunarizine dihydrochloride (FHC) is used for the prophylaxis to migraine. Flunarizine has solubility problems which is practically insoluble in water and alcohol. Nanoemulsion is the approach to increase the solubility of the insoluble drugs. In this research work the solubility of the poorly soluble FHC was successfully improved by preparing it as a nanoemulsion. Nanoemulsions can pass through the biological membrane easily so it can be delivered through nasal mucosa by which it may provide a quicker onset of action...

Glucocorticoids are the most widely used drugs for the treatment of hypersensitivity, however these drugs themselves and the excipients contained in commercial corticosteroid formulations are able to induce severe immediate-type hypersensitivity reactions. Reactions involving excipients have been confirmed to be IgE mediated by the demonstration of specific-IgE to excipients such as carboxymethylcellulose and lactose. In case of hypersensitivity reactions to corticosteroid preparations, a complete allergy work-up with skin tests and/or challenge tests should include testing excipients as well as the active ingredients...

BACKGROUND: At present, ischemic heart disease (IHD) is one of the main causes of morbidity and mortality world-wide. An important insight into both IHD pathophysiology and cardioprotection was achieved in 1986 when Murry et al. described for the first time the ischemic preconditioning (IP). IP can be defined as an innate phenomenon by which brief episodes of ischemia confer protection to a tissue from a subsequent more protracted ischemic insult. Suggested mechanisms explaining IP comprise the action of circulating substances (e...

BACKGROUND: Beta-lactam molecules are a family of drugs commonly used for their antibiotic properties; however, recent research has shown that several members of this group present a large number of other effects such as neuroprotective, antioxidant, analgesic or immunomodulatory capabilities. These properties have been used in both preclinical and clinical studies in different diseases such as hypoxic neuronal damage or acute and chronic pain. The present work briefly reviews the antibiotic effect of these molecules, and will then focus specially on the non-antibiotic effects of three beta-lactam subfamilies: penicillins, cephalosporins and beta lactamase inhibitors, each of which have different molecular structure and pharmacokinetics and therefore have several potential clinical applications...

BACKGROUND: Long term use of NSAIDS is mainly accompanied by major health implications such as gastrointestinal erosions, ulcerations and nephrotoxicity. These side effects arise from local irritation by the carboxylic acid moiety, that is common to most of NSAIDs (topical effect), in addition to decreased cytoprotective prostaglandin production. Therefore, in the medicinal chemistry research area, there is an ongoing need for the discovery of new, potent and safer anti-inflammatory lead compounds devoid of the irritant carboxylic acid moiety...

BACKGROUND: Oxygen has double-edge properties as it is essential for life, but can also provoke oxidative stress by protein & lipid per oxidation. The persistent oxidative stress and excess LPO induce several inflammatory mediators such as prostaglandins and leuckotrienes by activating enzymes cyclooxygenase and lipoxygenase. The per oxidation can be blocked by free radical scavengers as antiinflammatory agents. Most of the anti-inflammatory agents, which inhibit the above mentioned enzymes, are associated with side effects such as ulceration and bleeding in gastrointestinal tract; so the attention is focused on benzylideneacetophenones having antinflammatory, antioxidant and gastric protectant activities by virtue of free radical scavengers...
