Drug addiction has developed to a social illness. Changes in glutamate transmission have been recorded by the repeated administration of addictive drugs into VTA. In this investigation, In vivo microdialysis was used to study the effects of morphine on glutamate release from the ventral tegmentum area (VTA) in freely moving rats. Rats were anesthetized with chloral hydrate (350 mg/kg, i.p.) and...
Background and Purpose: Oral administrations have been used for many years as a main method comparing to other methods. Sustained release techniques have been a great interest recently. Matrix polymers are one of the ways used to prepare a sustained-release drug and are most widely used to prepare the controlled-release drugs. Cellulose derivatives are the most common ones. Solubilities of so...
داروی آلفازوسین متعلق به دسته داروهای قلبی عروقی می باشد که در درمان هایپرپلازی خوش خیم پروستات به عنوان خط اول درمان مطرح می باشد. این دارو به شکل قرص های immediate release با دوز 5/2 میلی گرم و قرص های extended release با دوزهای 5 و 10 میلی گرم موجود می باشد. از انجایی که این دارو با قابلیت درمانی بالا در کشور ما تولید نمی شود هدف ما بر این است که با تهیه فرمولاسیون فرم آهسته رهش این قرص با...
background: the development of injectable sustained-release products are of great interest to veterinary pharmaceuticals and animal health business. recently, great attention has been paid to in situ gel-forming chitosan/beta-glycerophosphate (chitosan/β-gp) solutions due to their good biodegradability and thermosensitivity. objectives: the general aim of this study was to prepare a novel in si...
Till date, most of the drugs have been given in conventional immediate release dosage form. Nimorazole is an anticancer drug, used as a hypoxic radiosensitizer in patients undergoing radiotherapy and no formulation has been available in the market till now. Hence, for the purpose to develop an immediate release dosage form, a statistical optimization process has been employed to quantify the ef...
Pills and capsules may release their contents within minutes of ingestion; these are immediate-release formulations. Pills and capsules may also release their contents after a time lag, or a little at a time, or in some other predetermined way; these are time-release formulations. Many drugs in psychiatry have been time-release formulated to reduce their local adverse effects in the gastrointes...
The purpose of this study was to assess the fluoride release of three fluoride- containing materials exposed to fluoride solutions. This study compared the initial fluoride release and release following re-fluoridation (neutral or acidic 2% NaF) of three different filling materials, conventional glass ionomer cement (CG1C), resin- modified glass ionomer cement (RMGIC), polyacid- modified compos...
objective(s): to investigate the chronopharmacological effects of growth hormone on executive function and the oxidative stress response in rats. materials and methods: fifty male wistar rats (36-40 weeks old) had ad libitum access to water and food and were separated into four groups: diurnal control, nocturnal control, diurnal gh-treated, and nocturnal gh-treated animals. levels of cu, zn sup...
In a supply chain, cross-docking is one of the most innovative systems for ameliorating the operational performance at distribution centers. Cross-docking is a logistics strategy in which freight is unloaded from inbound trucks and (almost) directly loaded into outbound trucks, with little or no storage in between, thus no inventory remains at the distribution center. In this study, we consider...
