Description of intervention(s) / exposure
Treatment: Drugs - Inhaled Melatonin (100 µg)
Treatment: Drugs - Oral Melatonin (4 mg)

Experimental: Inhaled Melatonin Arm - 100 µg daily of inhaled melatonin delivered by pressurized metered dose inhaler for two weeks before habitual bedtime.

Active comparator: Oral Melatonin Arm - 4 mg daily of orally delivered melatonin tablets for two weeks before habitual bedtime.


Treatment: Drugs: Inhaled Melatonin (100 µg)
An orally inhaled formulation of melatonin delivered by pressurised metered dose inhaler (pMDI) to be taken before bedtime. The pMDI will deliver a total of 100 µg of inhaled melatonin (2 x 50 µg/actuation). The investigational product is produced under Good Manufacturing Practice by Ab Initio Pharma Pty Ltd, a GMP certified manufacturer of pharmaceutical products.

Treatment: Drugs: Oral Melatonin (4 mg)
Two orally ingested tablets each containing 2 mg of melatonin (4 mg total) to be taken before bedtime.
