Study Groups

Single-Arm Crossover

Group Type: EXPERIMENTAL

Hezkue Sildenafil Oral Suspension

Intervention Type: DRUG

Hezkue® sildenafil oral suspension will be administered as a single oral dose in each study period under different alcohol intake conditions (such as with and without moderate alcohol consumption), according to the randomized crossover design. Pharmacokinetic, absorption, onset of action, and safety parameters will be assessed after each administration.

Hezkue® With Moderate Alcohol Intake

Participants will receive Hezkue® sildenafil oral suspension administered following standardized moderate alcohol intake in one study period. Pharmacokinetic, absorption, onset of action, and safety assessments will be conducted following dosing.

Group Type: EXPERIMENTAL

Hezkue Sildenafil Oral Suspension

Intervention Type: DRUG

Hezkue® sildenafil oral suspension will be administered as a single oral dose in each study period under different alcohol intake conditions (such as with and without moderate alcohol consumption), according to the randomized crossover design. Pharmacokinetic, absorption, onset of action, and safety parameters will be assessed after each administration.

Moderate Alcohol Intake

Intervention Type: OTHER

A standardized moderate amount of alcohol will be administered under controlled conditions prior to dosing with Hezkue® sildenafil oral suspension in designated study periods, according to the protocol-defined alcohol intake procedures.
