prescriptions written by general practitioners and medical specialists were studied and compared to determine the type, time of onset and clinical importance of drug-drug interactions (ddis) in an attempt to reduce further complications. in 2007, 28, 956, 638 prescriptions and 15, 610, 912 prescriptions in 2008 were filled by pharmacies affiliated with medical science universities. these prescr...

results: a total number of 117 patients were evaluated for adverse drug reactions, among them, 97 (82.9%) were considered to have immunological drug reactions. the most common symptoms of allergic drug reactions were morbilliform eruptions, serum sickness, dress (drug rash with eosinophilia and systemic symptoms), and toxic epidermal necrolysis. in 62 patients, anticonvulsant drugs had the prom...

conclusions as the results showed, the trend of activities was encouraging and some additional activities could be included to future programs relying on early-onset preventions. results summarizing the data led to three distinguished sections: 1) drug supply reduction activities; 2) drug demand reduction activities; 3) harm reduction activities. evidence acquisition in this report, authors gat...

background: due (drug utilization evaluation) studies can help identify and correct problems associated with irrational use of drugs. considering lack of data regarding how rational vancomycin is being used, we evaluated this due study in a referral infectious center to evaluate compliance with guidelines in terms of rational use of this valuable antibiotic. methods: this retrospective study wa...

benzoyl peroxide (bpo) is a first-line topical treatment in acne vulgaris, and it is superior to antibiotics, because the bacteria do not develop resistance to it. skin irritation is a common side effect, and it has been shown that controlled release of bpo from a delivery system to the skin could reduce the side effects while reducing percutaneous absorption. therefore, the purpose of the pres...

the drug pump protein mrp2 is a membrane drug efflux transporter widely distributed in normal and tumor tissues. its role is thought to be crucial for the disposition of many drugs and their substrates in different tissues. in this study, we aimed to examine the effects of systematic inflammation induced by lipopolysaccharide (lps) on the expression and function of this transporter in rats. jug...

the goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. the mesoporous silica nanoparticles were prepared by using tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); the prepared nanoparti...

the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...

to improve drug selectivity toward target cells, one interesting approach for drug delivery is to use polymer nanoparticles. a two-layered oniom becke3- lyp: uff calculation was carried out to study the structural and thermodynamic properties of the interaction between acetamide derivatives and the pca-peg-pca copolymers. the interaction enthalpies and the gibbs free energies between acetamide ...
