We hypothesized that increasing the dopaminergic tone with L-DOPA and the cholinergic tone with rivastigmine will enhance PAS-induced LTP, potentiation pharmacology, while increasing the GABAergic tone with baclofen and inhibiting glutamatergic neurotransmission with dextromethorphan will reduce it compared to placebo. Methods : Potentiation pharmacology this randomized controlled, double-blind cross-over within-subject study, potentiation pharmacology, 12 healthy participants received five sessions of PAS to the DLPFC in a random order, each preceded by the administration of placebo or one of the four active drugs.

Long-term potentiation is widely used as a model for memory formation. Recently, much information concerning this topic like the involvement of protein kinase C, arachidonic acid and N -methyl- d -aspartate receptors has been reported. In this review recent discoveries concerning long-term potentiation and the pharmacological implications for the development of cognition-enhancing drugs are discussed.

The probability of interactions increases with the number of drugs taken. The high rate of prescribed drugs in elderly patients year-old patients take an average of 5 drugs increases the likelihood of drug interactions and thus the risk that drugs themselves can be the cause of hospitalization. Drug interactions occur on pharmacodynamic and pharmacokinetic levels. Examples of pharmacodynamic interactions are simultaneous administration of a NSAID and phenprocoumon additive interaction , or of aspirin and ibuprofen antagonistic interaction. Pharmacokinetic interactions occur at the levels of absorption e. The systematic knowledge of drug interaction, in particular on the level of absorption, elimination, transport and drug metabolism may help to prevent adverse effects.

As complex diseases, especially cancer, are being treated with various drug cocktails, understanding the interactions among these drugs is increasingly vital to ensuring successful treatment regimens. However, the idea of synergy is not limited to only the biomedical realm and these ideas have developed across many different disciplines, as well. In this review, we first discuss the various terminology surrounding the idea of synergy, providing a comprehensive list of terms defined across numerous disciplines. We then review the most common methodology for detection and quantification of synergy, including the two most prominent reference models for describing additive interactions: Loewe Additivity and Bliss Independence. We also discuss advantages and limitations to each method, with a focus on the Chou-Talalay Combination Index method.

The current study was a double-blind randomized controlled within-subject cross-overdesign. The mechanism of protein kinase C activation. To our knowledge, this is the first study to assess the pharmacological modulation of DLPFC neuroplasticity in humans. All data processing and analyses were also completed under blind condition. The repeated measure factor that was used in the rmANOVA was the drug condition because each participant had PAS repeated five times, each time under one of the five drug conditions. Figure 2.
