A Review on Phosphodiesterase-5 Inhibitors as a Topical Therapy for Erectile Dysfunction

Area of Science:

• Pharmacology
• Urology
• Drug Delivery Systems

Background:

• Erectile dysfunction (ED) prevalence necessitates safer pharmacotherapies.
• Systemic ED treatments face challenges like drug interactions and contraindications.
• Research is shifting towards treatments with fewer side effects and contraindications.

Purpose of the Study:

• To review recent findings on topical 5-Phosphodiesterase-5 inhibitors (5-PDEIs) for ED.
• To provide a comprehensive overview of topical 5-PDEI therapy.
• To assess topical 5-PDEIs as an alternative to systemic treatments.

Main Methods:

• Extensive literature search on topical 5-PDEI therapy for ED.
• Evaluation of recent scientific reports and studies.
• Focus on formulation type, adsorption, and comparative efficacy.

Main Results:

• Topical 5-PDEIs demonstrate considerable potency with fewer complications than systemic use.
• Various topical formulations were evaluated for efficacy.
• Topical 5-PDEIs present an acceptable alternative therapy for ED.

Conclusions:

• Topical agents are promising for mild to moderate ED, especially when systemic treatments are contraindicated.
• Novel topical and transdermal delivery of 5-PDEIs enhances effectiveness.
• Topical 5-PDEIs offer a safer therapeutic option for erectile dysfunction management.
