Obstructive Sleep Apnea: Understanding

Obstructive Sleep Apnea: Overview

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder characterized by repeated partial or complete blockage of the upper airway during sleep. These episodes cause apnea or hypopnea, resulting in intermittent oxygen desaturation, sleep fragmentation, and repeated arousals. OSA is associated with excessive daytime sleepiness, fatigue, impaired cognition, and an increased risk of cardiovascular and metabolic complications.

 

OSA results from a combination of upper-airway anatomy and physiological factors that increase airway collapsibility during sleep. Major risk factors include obesity, older age, male sex, increased neck circumference, craniofacial abnormalities, menopause, family history, smoking, and nasal congestion. Excess fat around the neck can narrow the upper airway and increase its tendency to collapse during sleep.

 

During sleep, reduced activity of the upper-airway muscles can cause the airway to narrow or collapse in susceptible individuals. This leads to repeated episodes of apnea or hypopnea, followed by oxygen desaturation, carbon dioxide accumulation, and brief arousals that restore airway patency. Recurrent intermittent hypoxia and sleep fragmentation can increase sympathetic activity, oxidative stress, and inflammation, contributing to cardiovascular and metabolic complications.

 

Diagnosis involves clinical assessment followed by objective sleep testing. Overnight polysomnography (PSG) is the standard diagnostic test and measures airflow, respiratory effort, oxygen saturation, brain activity, and other physiological parameters during sleep. The apnea-hypopnea index (AHI) is used to assess disease severity: 5–<15 events/hour indicates mild OSA, 15–<30 indicates moderate OSA, and ≥30 indicates severe OSA. Home sleep apnea testing may also be used in selected patients.

 

Treatment aims to maintain airway patency, reduce respiratory events, and improve symptoms and quality of life. Continuous positive airway pressure (CPAP) is the main treatment, particularly for moderate-to-severe OSA, as it prevents airway collapse during sleep. Other options include weight management, mandibular advancement devices, BiPAP, and surgical interventions, depending on disease severity, anatomy, comorbidities, and treatment tolerance.

Product Description: IHL-42X

IHL-42X is an oral fixed-dose combination therapy of dronabinol and acetazolamide designed to act synergistically by targeting two physiological mechanisms involved in OSA. Dronabinol, a synthetic form of delta-9-tetrahydrocannabinol (THC), acts on cannabinoid receptors and is intended to stimulate upper-airway dilation, thereby helping reduce airway obstruction during sleep. Acetazolamide, a carbonic anhydrase inhibitor, induces a mild metabolic acidosis, which signals increased carbon dioxide levels to the body and stimulates ventilation. By combining these mechanisms, IHL-42X is intended to address both upper-airway dysfunction and ventilatory control instability, thereby reducing the frequency of apneas and hypopneas, measured by the Apnea-Hypopnea Index (AHI). Currently the drug is in Phase II/III stage of its development for the treatment of Obstructive Sleep Apnea.
