まとめ
抗薬であるゾニサミドは,低カロリーダイエットと併用すると,肥満の成人の体重減少を大幅に助けました. この予備試験では,ゾニサミドによる体重減少が,プラセボと比較して32週間にわたってより大きく示されました.
科学分野:
- 薬理学 薬理学とは
- クリニック・トライアル 臨床試験
- 肥満に関する研究
背景:
- ゾニサミド (Zonisamide) は,セロトナーギーおよびドーパミナーギー作用が知られている抗薬です.
- 体重減少は,以前のゾニサミドのエピレプシー試験で有害な効果として観察されました.
- この研究では,減量治療としてのゾニサミドの可能性を調査しました.
研究 の 目的:
- 肥満成人における体重減少を促進するゾニサミドの有効性を評価する.
- ゾニサミドの減量効果とプラセボの効果を比較する.
主な方法:
- 16週間のランダム化,ダブルブラインド,プラセボ対照試験,任意の16週間の延長.
- 肥満の参加者 (n=60) は,低カロリーな食事と併せてゾニサミドまたはプラセボを投与された.
- ゾニサミドの投与量は,体重減少の進展に基づいて,600 mg/dまで定位されました.
主要な成果:
- ゾニサミドの治療は,プラセボ (0.9kg) と比較して16週間 (P<.001) の後に体重減少 (5.9kg) が著しく増加した.
- 16週目までに,ゾニサミドの患者の57%が体重の少なくとも5%を減量し,プラセボ群では10%減量した (P<.001).
- 32週間の治療期間を延長すると,ゾニサミド群 (9.2kg) とプラセボ群 (1.5kg) (P<.001) の間で持続的な体重減少が示されました.
結論:
- ゾニサミドは,低カロリーダイエットと併用して,プラセボとダイエット単独と比較して,より優れた減量効果を示しました.
- この肥満治療の予備試験では,薬剤が良好に耐受され,副作用は最小限でした.

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Obesity
1.5K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Antiepileptic Drugs: Potassium Channel Activators
895
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
Ezogabine has gained approval as an adjunctive treatment...
