In clinical trials of treatments for chronic pain, the percentage of participants who withdraw early can be as high as 50%. Major reasons for early withdrawal in these studies include perceived lack of efficacy and adverse events. Commonly employed strategies for accommodating missing data include last observation carried forward, baseline observation carried forward, and more principled methods such as mixed model repeated measures and multiple imputation. All of these methods require strong and untestable assumptions concerning the conditional distribution of outcomes after dropout given the observed data...

Initially developed to generate new treatments for epilepsy, gabapentin, and pregabalin ("gabapentinoids") were engineered to mimic the action of GABA and to modulate GABA metabolism. Rather than their intended pharmacological action on GABA neurotransmission, instead, they exhibit a high affinity for the α2δ-1 and α2δ-2 subunits of voltage-activated calcium channels, wherein binding of gabapentinoids inhibits cellular calcium influx and attenuates neurotransmission. Despite a lack of activity on GABA levels, gabapentin and pregabalin are effective at suppressing seizures and subsequently approved as a new class of antiepileptic therapy for partial-onset epilepsy...

The chiral feature is a critical factor for the efficacy and safety of many therapeutic agents. At present, about 57% of marketed drugs are chiral drugs and about 99% of purified natural products are chiral compounds. There has been a tremendous potential of functional microorganisms and biocatalysts derived from them for the bioconversion of synthetic chemicals into drugs with high enantio-, chemo-, and regio-selectivities. Biocatalysis is becoming a key subassembly in the medicinal chemist's toolbox. In fact, the intermediates of many important therapeutic agents such as sitagliptin, pregabalin, ragaglitazar, paclitaxel, epothilone, abacavir, atorvastatin, rosuvastatin, and omapatrilat have been successfully synthesized via biocatalysis...

Neuropathic pain remains a significant unmet medical need. Several recommendations have recently been proposed concerning pharmacotherapy, neurostimulation techniques and interventional management, but no comprehensive guideline encompassing all these treatments has yet been issued. We performed a systematic review of pharmacotherapy, neurostimulation, surgery, psychotherapies and other types of therapy for peripheral or central neuropathic pain, based on studies published in peer-reviewed journals before January 2018...

Prevention of epilepsy is a great unmet need. Acute central nervous system (CNS) insults such as traumatic brain injury (TBI), cerebrovascular accidents (CVA), and CNS infections account for 15%-20% of all epilepsy. Following TBI and CVA, there is a latency of days to years before epilepsy develops. This allows treatment to prevent or modify postinjury epilepsy. No such treatment exists. In animal models of acquired epilepsy, a number of medications in clinical use for diverse indications have been shown to have antiepileptogenic or disease-modifying effects, including medications with excellent side effect profiles...

Introduction . Fibromyalgia syndrome (FMS) is a pain disorder with an estimated prevalence of 1-5%. It is associated with a variety of somatic and psychological disorders. Its exact pathogenesis is still unclear but is involved with neural oversensitization and decreased conditioned pain modulation (CPM), combined with cognitive dysfunction, memory impairment, and altered information processing. Connectivity between brain areas involved in pain processing, alertness, and cognition is increased in the syndrome, making its pharmacologic therapy complex...

Summary: We present three cases of acute diabetic neuropathy and highlight a potentially underappreciated link between tightening of glycaemic control and acute neuropathies in patients with diabetes. Case 1: A 56-year-old male with poorly controlled type 2 diabetes (T2DM) was commenced on basal-bolus insulin. He presented 6 weeks later with a diffuse painful sensory neuropathy and postural hypotension. He was diagnosed with treatment-induced neuropathy (TIN, insulin neuritis) and obtained symptomatic relief from pregabalin...

BACKGROUND: Approximately 50% of patients do not achieve seizure control with antiepileptic drug (AED) monotherapy, and polytherapy, with more than one AED, is often required. To date, no evidence-based criteria on how to combine AEDs exist. OBJECTIVE: This narrative review aimed to provide critical findings of the available literature about the role of pharmacodynamic AEDs' interactions in patients whose epilepsies were treated with polytherapy. METHODS: Electronic databases, Medical Literature Analysis and Retrieval System Online (MEDLINE) and Excerpta Medica dataBASE (EMBASE), were systematically searched to identify relevant studies on pharmacodynamic AEDs' interactions in patients with epilepsy...

There is a high prevalence of painful diabetic polyneuropathy (pDPN) with around one-third of all patients with diabetes suffering from pDPN. pDPN has debilitating consequences, with a major impact on morbidity and quality of life. Unfortunately, there is no globally licenced pharmacotherapy that modulates the underlying disease mechanisms to prevent or halt the progression of diabetic neuropathy. The cornerstone of treatment therefore remains optimising glycaemic control and cardiovascular risk factors, and symptom control...

Despite large efforts to test analgesics in animal models, only a handful of new pain drugs have shown efficacy in patients. Here, we report a systematic review and meta-analysis of preclinical studies of the commercially successful drug pregabalin. Our primary objective was to describe design characteristics and outcomes of studies testing the efficacy of pregabalin in behavioral models of pain. Secondarily, we examined the relationship between design characteristics and effect sizes. We queried MEDLINE, Embase, and BIOSIS to identify all animal studies testing the efficacy of pregabalin published before January 2018 and recorded experimental design elements addressing threats to validity and all necessary data for calculating effect sizes, expressed as the percentage of maximum possible effect...

Background and Objectives : Distal symmetrical polyneuropathy (DSPN) is one of the most common chronic complications of diabetes mellitus. Although it is usually characterized by progressive sensory loss, some patients may develop chronic pain. Assessment of DSPN is not difficult, but the biggest challenge is making the correct diagnosis and choosing the right treatment. The treatment of DSPN has three primary objectives: glycemic control, pathogenic mechanisms, and pain management. The aim of this brief narrative review is to summarize the current pharmacological treatment of painful DSPN...

The trigeminal nerve (V) is the fifth and largest of all cranial nerves and it is responsible for detecting sensory stimuli that arise from the craniofacial area. The nerve is divided into three branches: ophthalmic (V1), maxillary (V2) and mandibular (V3); their cell bodies are located in the trigeminal ganglia (TG) and they make connections with second order neurons in the trigeminal brainstem sensory nuclear complex (VBSNC). Ascending projections via the trigeminothalamic tract transmit information to the thalamus and other brain regions responsible for interpreting sensory information...
