概括
药物剂量显著影响处方级联,一种药物触发另一个药物. 高剂量的指数药物,如ACE抑制剂,他类药物,抗抑郁药和DCCBs增加了这些级联的风险,突出显示了剂量意识在临床实践中的重要性.
科学领域:
- 药监和药物安全 药监和药物安全
- 临床药理学 临床药理学
- 药物错误研究 药物错误研究
背景情况:
- 处方级联发生在新药被处方用于管理最初药物不良反应 (ADR) 时.
- 在许多处方级联中,剂量依赖关系的证据是有限的,尽管剂量降低是管理副作用的常见策略.
研究的目的:
- 为了研究各种指数药物的潜在处方级联中的剂量依赖关系,而这种联系以前是未知的.
- 分析药物剂量与随后药物的开始之间的关联.
主要方法:
- 一项队列研究利用了600多家荷兰药房 (2015-2020) 的处方序列对称性分析.
- 评估了18种潜在的处方级联,包括ACE抑制剂 (ACEI),他类药物,抗抑郁药和二皮里丁通道阻断剂 (DCCB).
- 使用世卫组织定义的每日剂量 (DDD),指数药物剂量被分为低 (<0.50 DDD),中等 (0.50-1.50 DDD) 和高 (>1.50 DDD).
主要成果:
- 在18个潜在的处方级联中,有12个呈现出剂量依赖关系.
- 血管激素转化酶抑制剂 (ACEI) 相关级联显示,调整后序列比率 (aSR) 随着剂量增加而增加,特别是在ACEI诱导的咳中.
- 对他类药物,抗抑郁药物和DCCB也观察到剂量依赖关系,但对质子抑制剂,利尿剂或NSAIDs没有观察到.

Dosage Regimens: Partial Pharmacokinetic Parameters
195
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...

Dosage Regimens: Designs and Approaches
350
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Pharmaceutical Poisoning: Potential Scenarios
19
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Determination of Multiple Dosing Parameters: Loading and Maintenance Doses
272
A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

Pharmacokinetic–Pharmacodynamic Relationship: Dose to Pharmacological Effect
22
A drug’s dosage and pharmacokinetic properties determine how quickly it acts, how intense its effects are, and how long it lasts. Higher doses increase drug concentration at receptor sites, producing a hyperbolic curve when pharmacologic response is plotted against drug dose. Converting this scale to a log-linear format results in a sigmoidal curve, better representing dose–response relationships.For drugs following a one-compartment model, the pharmacologic response is directly...

Drug Accumulation During Multiple Dosing: Repetitive IV Injections
318
Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
