چکیده

Introduction Epilepsy is a common neurological disorder that can cause anywhere from a brief cessation of responsiveness to severe muscle spasms with a loss of consciousness.1 This condition is usually controlled with antiepileptic drugs (AEDs). However, approximately 20% of patients with epilepsy are resistant to therapy with first-generation AEDs.2 Topiramate (Topamax®) is a second-generation AED approved by the FDA for the treatment of partial seizures (with or without secondarily generalized seizures), seizures associated with Lennox Gastaut Syndrome, and primary generalized tonic-clonic seizures in patients that are inadequately controlled by conventional first-generation AEDs.3 Topiramate has also been shown to be effective in the prophylactic treatment of migraine headaches.

Application of Differential Kinetic Method Using ANN with a New Synthetic Reagent for Simultaneous Spectrophotometric Determination of Mercury and Palladium

A new selective reagent was used for simultaneous determination of mercury and palladium in real samples with their different kinetic spectrophotometric properties. The method is based on the difference in the rate of the oxidation reaction of the recently synthesized reagent, nitro benzoyl diphenylmethylen phosphorane (N-BDMP), with Hg2+ and Pd2+. The kinetic profiles were monitored and record...

Development and Validation of an Ion Chromatography Method for Quantification of Ammonium Ions in STEALTH® Liposomes

Ammonium sulfate is one of the subsidiary components in the stealth liposome structure. The ratio of ammonium ion bound to liposome sphere to ammonium ions outside the liposome plays an important role in drug delivery formulation; accordingly, in order to quantify the ammonium ion in the liposome structure, a rapid and sensitive method was validated using a conductivity detector. Through this m...

Determination of trace anions in high-nitrate matrices by ion chromatography.

An ion chromatography method was developed to determine trace anionic contamination in matrices that have a high concentration of nitrate ion. Contaminant anions of interest were separated on an IonPac AS15 high-capacity anion-exchange column and detected by suppressed conductivity detection. An EG40 eluent generator was used to prepare high-purity and carbonate-free potassium hydroxide. Using ...
