まとめ
多くの抗真菌薬はCoccidioidesをin vitroで殺すことができるが,一部の薬は患者で達成可能な濃度よりも高い濃度を必要とする. 最低真菌殺菌濃度 (MFC) は変化し,コクシオイドマイコシスの治療選択に影響を与えます.
科学分野:
- 菌類学 菌類学とは

主な方法:
- Coccidioidesの臨床単離体で557件のin vitro殺菌試験を実施しました.
- 複数の抗真菌薬の最低真菌殺菌濃度 (MFC) を決定する.
- MFCを確立された最小抑制濃度 (MIC) と比較した.
主要な成果:
- 異なる抗真菌薬の間でMFCの有意な異質性が観察されました.
- ポサコナゾールは一般的に殺すのに最も低い濃度が必要であり,フルコナゾールはしばしば最も高い濃度が必要でした.

Drug toxicity: Drug–Drug Interaction
2
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...

Pharmacokinetics: Drug–Drug Interactions
469
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...

Bioequivalence of Drugs: Drugs with Multiple Indications
167
The concept of therapeutic equivalence (TE) in drugs with multiple indications is complex. A generic drug may be therapeutically equivalent to a brand-name product for one specific indication, but this doesn't necessarily mean it's equivalent for all other indications. Evidence of TE in one patient group and bioequivalence shown in healthy volunteers can support—but not confirm—TE for other indications. However, definitive proof requires individual clinical studies for each...

FDA Approved Drugs: Changes to Approved Drugs
277
Post-approval, manufacturers may modify an approved new or generic drug product. Such modifications can encompass alterations in the Active Pharmaceutical Ingredient (API), manufacturing process, formulation, batch size, manufacturing site, and container closure system (FDA Guidance for Industry, April 2004). Often, a drug product may undergo multiple changes.These modifications require careful evaluation to determine their potential impact on the drug product's identity, strength, quality,...

Tissue-Drug Binding: Localization of Drugs and its Significance
456
Body tissues, comprising approximately 40% of the body weight, are crucial in drug distribution and localization. These tissues can serve as drug storage sites, competing with plasma binding sites for drug molecules.
Drugs can bind to different tissue components, enhancing their distribution and localization. The factors influencing drug localization in tissues include the drug's lipophilicity, structural characteristics, tissue perfusion rate, and pH differences. These factors determine...

Factors Affecting Protein-Drug Binding: Drug Interactions
617
Drug interactions are a critical aspect of pharmacology and can occur when two or more drugs compete for the same binding site. This competition can result in one drug displacing another, altering the effect of the displaced drug. Drug interactions are complex processes that rely heavily on how much of the displacer drug is present and how strongly it can bind to the same sites as the displaced drug.
Displacement interactions can have varying outcomes, ranging from toxicity to virtually...
