Research Applications
- Intranasal Drug Delivery: PT-141 nasal spray is studied for the pharmacokinetics of melanocortin agonist delivery via the nasal mucosa. The intranasal route was used in early clinical development before transitioning to subcutaneous injection. Research examines nasal absorption efficiency, systemic bioavailability, and the time-to-onset of central effects compared to subcutaneous administration.
- Sexual Medicine: Nasal PT-141 is investigated for non-invasive arousal signaling research. Studies examine whether intranasal delivery provides sufficient CNS melanocortin receptor activation to produce meaningful sexual function effects, and whether the convenience of nasal administration improves research compliance in chronic sexual dysfunction study protocols.
- Pharmaceutical Sciences: PT-141 nasal spray formulation research examines optimal delivery parameters for a CNS-active peptide. Studies investigate spray volume, droplet size distribution, pH optimization, and preservative systems to maximize nasal bioavailability while maintaining formulation stability and patient acceptability in clinical research settings.
Reconstitution Protocol
- 1 Remove the flip-off cap and wipe the rubber stopper with an alcohol swab.
- 2 Using a sterile syringe, draw the desired volume of bacteriostatic water (BAC water).
- 3 Insert the needle into the vial at an angle and slowly dispense the water down the inside wall — do not spray directly onto the powder.
- 4 Gently swirl (do not shake) the vial until the powder is fully dissolved.
- 5 Label the vial with the reconstitution date and concentration.
Storage Conditions
Unreconstituted
Store at -20°C to 4°C (freezer or refrigerator). Stable for 24+ months.
Reconstituted
Refrigerate at 2–8°C. Use within 30 days for optimal stability.
Avoid
Repeated freeze-thaw cycles, direct sunlight, and temperatures above 25°C.
Always note the reconstitution date on the vial label to track shelf life accurately.
Safety & Compliance
- Wear nitrile gloves and safety goggles when handling research compounds.
- Work in a clean, controlled environment (laminar flow hood recommended).
- Dispose of sharps and used materials in approved biohazard containers.
- This product is for laboratory research use only (RUO) — not for human or veterinary use.
