まとめ
独立系泌尿器科グループによる院内処方の導入は、進行性前立腺癌に対する経口特化型薬剤の処方を大幅に増加させました。この変化は、患者が地域の市場で重要な治療法へのアクセスを改善します。
科学分野:
- 腫瘍学; 泌尿器科学; ヘルスサービスリサーチ
- Oncology; Urology; Health Services Research
背景:
- 進行性前立腺癌の治療は経口特化型薬剤へと移行しています。; 泌尿器科診療所は、これらの治療法の管理に関与を増しています。; 一部の泌尿器科グループは、患者への直接的な薬剤配送のために院内処方を提供しています。
- Advanced prostate cancer treatment is shifting towards oral specialty drugs.; Urology practices are increasingly involved in managing these therapies.; Some urology groups offer in-office dispensing for direct patient medication delivery.
研究 の 目的:
- 泌尿器科グループの特徴を調査すること。; 進行性前立腺癌治療における院内処方が経口特化型薬剤の使用に与える影響を評価すること。
- To examine the characteristics of urology groups that adopt in-office dispensing.; To assess the impact of in-office dispensing on oral specialty drug utilization in advanced prostate cancer care.
主な方法:
- 従来のメディケア(2011-2019年)における進行性前立腺癌の男性を対象とした後ろ向きコホート研究。; 院内処方のある泌尿器科グループとない泌尿器科グループの比較。; 多変量ロジスティック回帰および差分の差分分析。
- Retrospective cohort study of men with advanced prostate cancer in Traditional Medicare (2011-2019).; Comparison of urology groups with and without in-office dispensing.; Multivariable logistic regression and difference-in-differences analysis.
主要な成果:
- 大規模な診療所規模、患者数の増加、社会的脆弱性の低下、競争の減少、および放射線治療室の所有は、院内処方導入と関連していました。; 採用している泌尿器科グループのある市場では、1000人あたり46件の経口特化型薬剤処方が大幅に増加しました。
- Large practice size, increasing patient volume, lower social vulnerability, reduced competition, and radiation vault ownership were associated with in-office dispensing adoption.; Markets with adopting urology groups saw a significant increase of 46 oral specialty drug prescriptions per 1000 men.
結論:
- 独立系泌尿器科グループによる院内処方は、進行性前立腺癌に対する経口特化型薬剤の使用増加と関連しています。; このモデルは、薬剤へのアクセスを向上させ、患者の治療アドヒアランスを改善する可能性があります。
- In-office dispensing by independent urology groups is linked to increased use of oral specialty drugs for advanced prostate cancer.; This model can enhance medication access and potentially improve treatment adherence for patients.

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Factors Influencing Drug Absorption: Presystemic Elimination
805
The pharmacokinetic journey of oral drugs begins with a crucial first pass through the hepatic portal system, called the first-pass effect. This first pass significantly impacts bioavailability — the proportion of a drug that enters systemic circulation and is available for therapeutic action. The primary route sees the drug absorbed by intestinal membranes and then shunted to the liver via the hepatic portal vein. Here, pre-systemic elimination occurs as drugs face metabolism or biliary...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
245
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Prodrugs
3.9K
Prodrugs are a class of pharmaceutical compounds that undergo a biotransformation process within the body to be converted into a pharmacologically active drug. Prodrugs are designed to improve the therapeutic properties of the parent drug, such as enhancing bioavailability, increasing stability, or reducing toxicity. The concept of prodrugs revolves around modifying the chemical structure of the original drug to make it more effective or convenient for administration.
