概括
过度活跃的膀 (OAB) 单用托尔特罗丁或米拉贝格朗的单一治疗并没有改善大鼠的炎症诱导的膀过度活跃. 两种药物都没有改变氧化 (NO) 水平,这表明组合疗法可能对治疗囊炎的OAB优越.
科学领域:
- 药理学 药理学是指药理学的学科.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 炎症研究的研究.
背景情况:
- 单一治疗对于过度活性膀 (OAB) 是常见的,但联合治疗可能更有效,特别是在并发性囊炎时.
- 氧化 (NO) 在OAB病理生理学和治疗中的作用仍然不完全理解.
研究的目的:
- 在炎症诱导的OAB大鼠模型中研究托尔特罗丁 (抗肌肉素) 和mirabegron (β3激动剂) 单一治疗的疗效.
- 探索氧化 (NO) 在这些OAB药物的治疗作用中的参与.
主要方法:
- 鼠被预先用tolterodine或mirabegron治疗,然后用cyclophosphamide诱导膀炎症和过度活动.
- 评估了流参数,并测量了尿液中的NO水平.
- 膀组织使用免疫组织化学检查炎症.
主要成果:
- 环胺诱导了膀显著过度活跃和炎症.
- 无论是托尔特罗丁,还是米拉贝格朗单疗法都没有显著缓解诱导的过度活跃或炎症.
- 虽然炎症增加了NO的产生,但这些药物并没有增强它;相反,它们显著降低了炎症膀中的NO水平.
结论:
- 在这种大鼠模型中,托尔特罗丁和米拉贝格朗单独治疗对炎症诱导的OAB无效.
- 药物对NO生产的影响表明复杂的相互作用,这并不支持它们在这种情况下的有效性.
- 结果间接支持组合疗法作为潜在的优越治疗OAB与囊炎,保证进一步调查NO的作用.

Drugs for Treatment of Diarrhea-Predominant IBS
140
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs for Treatment of Constipation-Predominant IBS
125
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
202
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Parkinson's Disease: Treatment
185
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents
170
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...
