概括
二元和三元溶剂系统显著增强皮洛克奥拉 (OPX) 的皮肤透,与单一溶剂不同. 在PG:TC (75:25) 系统中,通过皮肤进行抗应用的OPX输送率最高.
科学领域:
- 皮肤透和配方科学.
- 化品和制药成分的交付.
背景情况:
- 角层 (SC) 屏障保护皮肤免受微生物的侵扰;其破坏可能导致皮等疾病.
- 头发涉及SC化,与马拉塞西亚真菌有关,促使在治疗中使用像皮洛克奥拉 (OPX) 这样的抗真菌剂.
研究的目的:
- 研究各种单一,二元和三元溶剂系统对皮肤相互作用和透Piroctone olamine (OPX) 的影响.
主要方法:
- 评估的单一,二进制 (PG:TC) 和三进制溶剂系统含有1% (w/v) 的OPX.
- 在有限剂量条件下利用热分离的人类表皮进行24小时透实验.
- 进行了质量平衡研究以量化OPX分布.
主要成果:
- 单一溶剂没有观察到OPX透.
- 在二元和三元溶剂系统中,OPX的显著皮肤透发生了.
- 二元系统PG:TC (75:25) 显示了最高的OPX透率,其次是PG:PGML:LAB (60:30:10) 三元系统.
结论:
- 这项研究是第一个在各种溶剂系统 (单,二进制,三进制) 中探索OPX透的研究.
- 与纯溶剂相比,混合溶剂系统,特别是二进制和三进制,对于提高OPX的皮肤透和保留至关重要.

Drug Delivery: Miscellaneous Routes
355
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.
Transdermal patches transport drugs...

Hand hygiene
3.3K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Non-Oral Extravascular Drug Absorption Routes
218
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.
Lipophilic drugs that are stable at salivary pH (6) and exhibit minimal binding to the oral mucosa are absorbed more...

Drug Delivery: Overview
296
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Indirect-Acting Cholinergic Agonists: Pharmacokinetics
987
Indirect-acting cholinergic agonists, or anticholinesterases, enhance the body's cholinergic activity by inhibiting acetylcholine's breakdown. They are categorized as reversible or irreversible agents based on their mechanism of action. They are further classified into short-acting, intermediate-acting, and long-acting agents based on their duration of action.
Reversible agents containing quaternary amines, such as neostigmine and edrophonium, are not easily absorbed orally because they...

Routes of Drug Administration: Parenteral
2.0K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
