Vulvodynia Study Endorsing Gabapentin for Pelvic Muscle Pain: An In-depth Look

Sexual pain in women remains a difficult and elusive medical condition to treat. Provoked vulvodynia current recommended therapies include pelvic floor physical therapy and psychological interventions including cognitive behavioral therapy (CBT) and sexual counseling.1 Pharmacologic options remain limited to topical lidocaine, hormonal cream (typically estrogen + testosterone), and tricyclic antidepressants and their evidence for use remains mixed at best. Vulvodynia etiology is multifactorial and likely involves central sensitization, muscle and tissue nociception, and mucosal mechanoreceptor dysfunction

The state of naloxone: Access amid a public health crisis

Over the past decade, opioid use has been at the forefront of a public health crisis throughout the United States. In response to the tremendous negative societal, personal, and economic impacts that the growing opioid crisis has caused, several governmental agencies began to respond. These efforts include declaration of a nationwide public health emergency, increased public health surveillance of the epidemic, research support for pain and addiction, and increased access to overdose-reversing drugs such as naloxone. Naloxone access, in particular, has become a priority. In the United States, pharmacists have had the opportunity to play a crucial role in promoting access to naloxone. Since initial approval by the Food and Drug Administration (FDA) in 1971 as an antidote to opioid agonist overdose, naloxone access has evolved significantly. Today many states have authorized standing orders for naloxone, allowing it to be dispensed by pharmacists without a patient-specific prescription, and all 50 states and the District of Columbia allow medical providers to prescribe take-home naloxone to at-risk patients. While the opioid epidemic itself remains a contentious topic of political, ethical, and medical debate, it is widely acknowledged that mitigation strategies that could lessen morbidity and mortality are essential. Improved access to naloxone is one such strategy which remains at the forefront during this public health crisis

Open-Label Adhesion Performance Study of a Prescription Lidocaine Topical System 1.8% versus Three Lidocaine-Containing Over-the-Counter Patches in Healthy Subjects.

PurposeThis study evaluates and compares the clinical adhesion performance of a prescription lidocaine topical system 1.8% versus two different over-the-counter (OTC) lidocaine patches 4% and an OTC combination menthol and lidocaine patch 1%/4% in human subjects.Patients and methodsThis study was an open-label, randomized, four-treatment, four-sequence, Phase 1 adhesion performance study in healthy adult volunteers (N = 24). Lidocaine topical system 1.8% (R) and the three OTC patch products (T1, T2, and T3) were separately applied for 12 hours. Adhesion of all products was scored at 0, 3, 6, 8, and 12 hours post-application.ResultsThere were no issues with the conduct of the study. Overall, the majority (≥59.1%) of subjects treated ("patched") with the lidocaine topical system 1.8% (R) demonstrated ≥90% adhesion (FDA adhesion score 0) throughout the 12-hour administration period versus 27.3% of subjects treated with OTC lidocaine patch 4% (T1), 22.7% of subjects treated with OTC lidocaine patch 4% (T2), and 18.2% of subjects treated with OTC menthol/lidocaine patch 1%/4%. Only one subject (4.5%) treated with lidocaine topical system 1.8% was observed with <75% adhesion (FDA adhesion score <2) versus 11 (50.0%) and 10 (45.5%) for the two OTC lidocaine patches 4% (T1 and T2), respectively, and 13 (59.1%) subjects for the OTC menthol/lidocaine patch 1%/4%. There were no complete detachments observed for lidocaine topical system 1.8%, whereas 50.0% and 31.8% complete detachments were observed for the two OTC lidocaine patches 4% (T1 and T2), and 27.3% complete detachments were observed for the OTC menthol/lidocaine patch 1%/4%. No adverse events were observed for any of the treatments.ConclusionLidocaine topical system 1.8% demonstrated superior adhesion relative to the three lidocaine-containing OTC products over the 12-hour treatment period

Opioids and pituitary function: expert opinion.

PURPOSE Opioids are highly addictive potent analgesics and anti-allodynics whose use has dramatically increased in recent decades. The precipitous rise in opioid dependency and opioid use disorder is an important public health challenge given the risks for severely adverse health outcomes. The long-term opioid impact on hypothalamic-pituitary axes is particularly underappreciated among both endocrinologists and primary care physicians. We review the effects of opioids on hypothalamic-pituitary-target gland function and their implications for clinical practice. METHODS Experts in hypothalamic-pituitary disorders and opioid pharmacology reviewed recently published literature and considered strategies for diagnosing and managing these opioid-induced endocrine effects. RESULTS Opioid suppression of hypothalamic-pituitary axes can lead to hypogonadotropic hypogonadism, central adrenal insufficiency, and hyperprolactinemia. These important clinical manifestations are often under-estimated, poorly evaluated, and typically either untreated or not optimally managed. Data on biochemical testing for diagnosis and on the effect of hormone replacement in these patients is limited and prospective randomized controlled studies for guiding clinical practice are lacking. CONCLUSIONS Patients should be informed about risks for hypogonadism, adrenal insufficiency, and hyperprolactinemia, and encouraged to report associated symptoms. Based on currently available evidence, we recommend clinical and biochemical evaluation for potential central adrenal insufficiency, central hypogonadism, and/or hyperprolactinemia in patients chronically treated with opioids as well as the use of current expert guidelines for the diagnosis and treatment of these conditions
