          Abstract

          Idiosyncratic reactions to a large number of drugs have been reported to cause choroidal detachment and secondary angle-closure glaucoma (ACG). We report a case of bilateral acute ACG and peculiar choroidal effusion following administration of oral acetazolamide immediately after cataract surgery. Few cases of acute secondary ACG with choroidal effusion and anterior shift of the lens-iris diaphragm have been associated with acetazolamide compared with other sulfonamides. As far as we are aware, posterior involvement with retinal folds and papillary edema due to acetazolamide has not been described before.

          Treatment of idiopathic intracranial hypertension: topiramate vs acetazolamide, an open-label study.

          OBJECTIVES - To assess the efficacy of topiramate in the treatment of idiopathic intracranial hypertension (IIH) and to compare it with acetazolamide. METHODS - Fourty patients diagnosed as IIH and randomly assigned to treatment with either acetazolamide or topiramate were assessed prospectively. Improvement in the visual fields at the end of third, sixth and twelfth months were taken into consideration. RESULTS - The demographic, clinical features and the cerebrospinal fluid (CSF) pressure of the two treatment groups were similar at the beginning of the study. When the follow-up visual field grades were compared with the visual field grades at the beginning of the study in each group a statistically significant improvement was detected with both drugs. When the results of the two treatment groups were compared with each other no statistically significant difference was present. Prominent weight loss was recorded in the topiramate group. CONCLUSIONS - Topiramate seems to be effective in the treatment of IIH. Weight reduction as well as the reduction of the CSF formation is the possible mechanism of action.

            Sulfonamides: a patent review (2008 - 2012).

            The primary sulfonamide moiety is present in many clinically used drugs, such as diuretics (furosemide, indapamide, chlorthalidone, thiazides); carbonic anhydrase (CA) inhibitors (CAIs) (including acetazolamide, dichlorophenamide, dorzolamide and brinzolamide); antiepileptics (zonisamide and sulthiame); the antipsychotic sulpiride and the cycloxygenase 2 (COX2) inhibitors celecoxib and valdecoxib. Recently, novel drugs have been launched, such as apricoxib and pazopanib, which also incorporate this group. The article presents the main classes of sulfonamides investigated between 2008 and 2012. Specifically, the authors review the scientific and patent literature on CAIs, COX2 inhibitors, pazopanib and its congeners, which are multi-targeted receptor tyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-a/β, and c-kit. Most patents deal with sulfonamide CAIs incorporating NO-donating moieties as antiglaucoma agents, or with compounds targeting the tumor-associated isoforms CA IX/XII. The antidandruff actions of sulphonamides, which inhibit yeast CAs, were also claimed. Apricoxib (a COX2 inhibitor) and pazopanib, a tyrosine kinase inhibitor, show significant antitumor activity and several patents deal with these drugs. There is a constant need of novel sulfonamides to act as selective antiglaucoma drugs (targeting CA II), as antitumor agents/diagnostic tools (targeting CA IX/XII), and to treat and diagnose other disease. This privileged structural motif is likely to be present in other drugs in the future.

              Topiramate-associated acute, bilateral, secondary angle-closure glaucoma.

              To evaluate spontaneous reports of ocular side effects associated with topiramate use. Retrospective case series. One hundred fifteen case reports, primarily of a specific ocular syndrome (acute secondary angle-closure glaucoma), were collected from spontaneous reporting systems: the Drug Safety section of Ortho-McNeil Pharmaceuticals, Inc. (Raritan, NJ), the Food and Drug Administration (Rockville, MD), the World Health Organization (Uppsala, Sweden), the National Registry of Drug-Induced Side Effects (Casey Eye Institute, Oregon Health & Science University, Portland, Oregon), and the world literature. The data were evaluated using the World Health Organization Causality Assessment Guide to the certainty of a suspected adverse drug reaction. Eighty-six cases of acute-onset glaucoma (83 bilateral and 3 unilateral), 17 cases of acute bilateral myopia (up to 8.75 diopters), 9 cases of suprachoroidal effusions, 3 cases of periorbital edema, and 4 cases of scleritis were reported. In those cases for which management was reported, 38% had laser or surgical peripheral iridectomy (21 cases). In the "certain" category of the World Health Organization classification system, the following are caused by topiramate therapy: abnormal vision, acute secondary angle-closure glaucoma, acute myopia, and suprachoroidal effusions. All findings are reversible if recognized early and if the drug is discontinued. The first presenting symptom of acute secondary angle-closure glaucoma in many patients was blurring of vision. Peripheral iridectomy is ineffective for this type of angle-closure glaucoma.
