The present data for the first time demonstrate the possible implication of routine caffeine intake in the acceleration of pathological conditions of periodontitis. Thus, we propose that chronic caffeine intake is one of the possible risk factors in the advancement of pathology in the periodontitis patient. Further research in this area is warranted.
Voltage-gated sodium channel blockers like phenytoin and carbamazepine have long been used in the treatment of epilepsy. Brain sodium channels continue to be an important target of many newer second-generation (fosphenytoin, oxcarbazepine, lamotrigine, felbamate, topiramate, zonisamide) and third-generation (eslicarbazepine, brivaracetam, carisbamate, fluorofelbamate, elpetrigine, lacosamide, rufinamide, safinamide, vinpocetine) antiepileptic drugs (AEDs). Some of the newer drugs show either state-dependent antiepileptic action or sodium channel subtype selectivity, although most agents do not differentiate between these channel subtypes. The present review highlights the preclinical and clinical efficacy, pharmacokinetics, drug interactions and adverse event profiles. It also addresses AED selection of sodium channel blockers that constitutes the third generation of AEDs.
Various levels of maternal caffeine ingestion during pregnancy were investigated to determine whether caffeine will affect the mineral contents of the growing bones of fetal rats. On day 8 of gestation, rat dams were fed with a 20% protein diet supplemented with 0.5 mg, 1 mg, or 2 mg caffeine/100 g of dams body weight as an experimental group and the same without caffeine as a control until day 22 of gestation. Fetuses were removed by cesarean section on day 22 and mandibular bones were removed to study the mineral contents of calcium, phosphorus, magnesium, and zinc. Although the mandible weighed more in the 0.5-mg caffeine group as compared to the controls, an additional increase of caffeine resulted in a decrease in weight. All calcium, magnesium, and zinc contents per bone decreased in the 1- and 2-mg caffeine groups as compared to either controls or 0.5-mg caffeine group, whereas phosphorus stayed relatively constant regardless of the different levels of caffeine intake. When data are expressed as per gram of bone tissue, most of the mineral contents among the groups disappeared suggesting that normal growth and development of the fetal bone are impaired as a results of maternal caffeine intake. Caffeine intake during gestation in the present study indicates that different levels of caffeine intake may exert not only different effects on mineral contents in bone development, but also affect the growth of the fetal bone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
