Publication Open Access The Prevalence of Potential Drug-Drug Interactions in CKD-A Retrospective Observational Study of Cerrahpasa Nephrology Unit(2022-02-01T00:00:00Z) BUKHARI, ANDLEEB; Sonmez, Ikbal; Kose, Cagla; OKTAN, BURHANEDDİN; Alagoz, Selma; Sonmez, Haktan; Hussain, Adil; AKKAN, Ahmet Gökhan; AKKAN, AHMET GÖKHANBackground and Objectives: Chronic kidney disease (CKD) is usually linked with polypharmacy and patients are invariably at risk of complex medication regimens. The present study was designed to estimate the potential drug-drug interactions (pDDIs) through the prescription patterns provided to patients of the Nephrology Transplant Unit of Cerrahpasa Medical Faculty patients. Materials and Methods: 96 patients were included in the study. pDDIs among every combination of the prescribed drug were analyzed using the Thomson Reuters Micromedex. Results: We found 149 pDDIs making 2.16 interactions per prescription with incidence rates of 69.7%. Approximately 4.1% of interactions were of significant severity, 75.1% moderate severity, and 20.8% were classified as minor pDDIs. The most frequent interactions were found between iron and aluminum, calcium or magnesium-containing products (21.37%), calcium channel blockers and beta-blockers (8.96%); and aspirin and aluminum, calcium, or magnesium-containing products (7.58%). We identified 42 drug pairs with probability of clinical significance. The most commonly reported clinical outcomes of the pDDIs were hypo- or hypertension (39.24%), decreased drug efficacy (24.05%), and arrhythmia (9.49%). Aluminum, calcium, or magnesium-containing drug products (33.10%) constituted the primary class of drugs involved in interactions. Conclusions: This study showed pharmacodynamics (49%), pharmacokinetics (42.94%) interactions, polypharmacy and gender as determinant of pDDIs. A comprehensive multicenter research is required to decrease the morbidity and ease the state burden.Publication Metadata only Investigation of the pharmacological potential of myricetin on alcohol addiction in mice(2022-01-01T00:00:00Z) Yunusoglu, Oruc; BUKHARI, ANDLEEB; Turel, Canan Akunal; Demirkol, Muhammed Hamdi; Berköz, Mehmet; AKKAN, Ahmet Gökhan; AKKAN, AHMET GÖKHANAlcohol addiction is one of the leading causes which is associated with morbidity and mortality with outcomes in high healthcare and economic costs. Myricetin is a flavonoid that demonstrates therapeutic actions in many central nervous system diseases. In the current study, the conditioned place preference (CPP) tests were performed W examine the effects of myricetin on ethanol reward. During conditioning, intraperitoneal (i.p) administration of ethanol (2 g/kg) and serum physiologic were given on alternate days for 8 days. In order to evaluate the effect of myricetin on the development of alcohol addiction, myricetin was injected into mice 30 minutes before ethanol administration. Subsequently, a daily myricetin injection was performed to evaluate the effect of myricetin on the extinction of alcohol addiction. Finally, ethanol was administered 900 seconds after different dose myricetin administration, and reinstatement was evaluated immediately thereafter. Systemic ethanol (2 g/kg, i.p) administration significantly produced CPP. Myricetin (5 and 10 mg/kg, i.p) attenuated the development of ethanol addiction (p < 0.05). Systemic myricetin injections immediately after each extinction period precipitated extinction and decreased reinstatement (10 mg/kg, i.p, p < 0.05, respectively). Ethanol alone and in combination with myricetin did not change locomotor activity and motor coordination. As a result, it can be suggested that myricetin is effective in attenuating the rewarding effect of alcohol in mice and can be used for the adjunctive therapy for alcohol addiction. In addition, it will be appropriate to conduct mechanistic experimental studies regarding these results in the future.
