Insights

New antifungal drugs are in development to combat rising invasive fungal infections (IFIs) and resistance. Promising candidates include novel azoles, glucan synthase inhibitors, and orotomides, offering improved safety and administration options.

Area of Science:

  • Pharmacology
  • Infectious Diseases
  • Drug Development

Background:

  • Invasive fungal infections (IFIs) present a significant and increasing global health challenge.
  • Current antifungal therapies face limitations due to toxicity, drug interactions, and emerging resistance.
  • There is a critical need for novel antifungal agents with improved efficacy and administration routes.

Purpose of the Study:

  • To review antifungal drugs currently in clinical development pipelines.
  • To highlight agents with novel mechanisms of action and improved therapeutic profiles.
  • To discuss the potential of new antifungals for ambulatory and enhanced patient treatment.

Main Methods:

  • Review of clinical trial data for emerging antifungal agents.
  • Analysis of pharmacological properties, safety profiles, and resistance patterns.
  • Comparison of novel antifungals with existing treatments.

Main Results:

  • Isavuconazole, a new azole, demonstrates an improved safety profile and reduced drug-drug interactions (DDIs).
  • Rezafungin (CD101) and SCY-078 represent novel glucan synthase inhibitors (GSIs) with potential for once-weekly or oral administration, including against resistant strains.
  • New formulations of amphotericin B and the novel orotomide class show promise for broad-spectrum activity without cross-resistance.

Conclusions:

  • The antifungal drug pipeline shows promising candidates addressing limitations of current therapies.
  • Novel agents like isavuconazole, GSIs, and orotomides offer potential for improved safety, efficacy, and patient convenience.
  • Continued development is crucial to combat the growing threat of invasive fungal infections.

Pharmacokinetics: Drug–Drug Interactions

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 Indications01:09

Bioequivalence of Drugs: Drugs with Multiple Indications

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

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,...

Factors Influencing Drug Absorption: Drug Dissolution

The pharmacokinetic journey of drugs from solid oral dosage forms into systemic circulation is multifaceted. It begins with disintegration, a prerequisite ensuring a solid dosage form's subdivision into minute particles. Dissolution occurs next as these granulated entities solubilize in gastrointestinal fluids. This solubilization is crucial for the succeeding stage, permeation, which describes the traversal of the drug across the intestinal membrane and its subsequent entry into the blood...

Factors Affecting Protein-Drug Binding: Drug-Related Factors01:18

Factors Affecting Protein-Drug Binding: Drug-Related Factors

Drug binding to proteins is a complex phenomenon influenced by various drug-related factors, each playing a significant role in the interaction between drugs and proteins within the body.
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In...

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...
