まとめ
バルプロ酸(VPA)製剤は、双極I型および統合失調感情障害の症状コントロールに影響します。徐放性VPAは、興奮に対する必要に応じたベンゾジアゼピンおよび抗精神病薬の投与量を減らす可能性があります。
科学分野:
- 精神医学;薬理学;臨床治療学
背景:
- 即放性(IR)、遅延放出性(DR)、および徐放性(ER)バルプロ酸(VPA)製剤間には薬物動態学的変動が存在します。;これらの薬物動態学的違いは、治療効果と患者のアウトカムに影響を与える可能性があります。;必要に応じた(プロ レ ナタ、PRN)投薬は、興奮を管理するための定期的な投薬の有効性の指標として役立ちます。
研究 の 目的:
- 異なるVPA製剤(IR、DR、ER)間で興奮に対して投与された必要に応じたベンゾジアゼピンおよび抗精神病薬の数を比較すること。;VPA製剤と双極I型または統合失調感情障害患者における必要に応じた投薬の必要性との関連を調査すること。
主な方法:
- 維持VPA療法を受けている双極I型または統合失調感情障害の患者150人の後ろ向きレビュー。;主要評価項目:興奮に対する必要に応じたベンゾジアゼピンおよび/または抗精神病薬の1日平均投与量。;副次評価項目:VPA総1日投与量(TDD)。統計分析には、ANOVAおよび階層的多重回帰が含まれました。
主要な成果:
- VPA製剤は、抗精神病薬単独を含む、必要に応じた抗精神病薬および/またはベンゾジアゼピンの1日平均投与量と有意に関連していました。;これらの関連は、年齢、性別、人種、およびVPA TDDなどの交絡因子を調整した後も有意なままでした。
結論:
- VPAの製剤は、興奮を管理するために必要に応じた投薬の必要性に有意に影響します。;これらの発見は、症状コントロールにおける製剤依存性の違いを示唆しており、精神医学的状態に対する最適なVPA送達に関するさらなる調査を保証します。

Mania and Antimanic Drugs: Overview
706
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Dosage Regimen: Individualization
230
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
1.0K
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Dosage Regimen: Fixed Dose
2.5K
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

Drug Dosage Regimen: Overview
4.6K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Dosage Regimens: Partial Pharmacokinetic Parameters
226
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...
