Summary
Drug-eluting balloons offer a promising advancement for critical limb ischemia management in below-the-knee disease. These devices show favorable results, potentially improving outcomes compared to traditional methods.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Devices
Background:
- Critical limb ischemia (CLI) from below-the-knee (BTK) disease presents management challenges due to patient comorbidities and diffuse vascular involvement.
- The BASIL study indicated equivalence between bypass surgery and angioplasty, but percutaneous techniques have since evolved significantly.
- Drug-eluting balloons (DEBs) represent a major advancement, offering theoretical advantages over standard balloons and metallic stents for BTK lesions.
Purpose of the Study:
- To discuss the rationale for employing drug-eluting balloons in the complex treatment of BTK critical limb ischemia.
- To review the findings of recent clinical trials evaluating DEBs for BTK lesions.
Main Methods:
- Review of existing literature and clinical trial data on drug-eluting balloons for below-the-knee critical limb ischemia.
- Discussion of the theoretical advantages of DEBs compared to conventional angioplasty and stenting.
Main Results:
- Two clinical trials reported favorable outcomes using the In.Pact Amphirion paclitaxel-eluting balloon for BTK lesions.
- DEBs present potential benefits for infra-popliteal lesions, addressing restenosis and disease progression.
Conclusions:
- Drug-eluting balloons are a significant development in managing below-the-knee critical limb ischemia.
- Evidence suggests DEBs, like the paclitaxel-eluting balloon, offer promising results in this challenging patient population.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
01:24Site-Targeted Drug Delivery Systems: Polymeric Carriers
Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...
01:26Oral Drug Delivery Systems: Continuous-Release Systems
Continuous-release drug delivery systems offer a strategic approach to maintaining therapeutic drug levels over extended periods following oral administration. By modulating the release rate of active pharmaceutical ingredients, these systems minimize fluctuations in plasma concentrations, which enhances clinical efficacy and reduces the need for frequent dosing. Such characteristics make them particularly advantageous in managing chronic diseases where patient adherence and stable drug...

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 through the...

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
