Motilin Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Motilin. All information is for educational purposes only.

Quick Answer

Motilin is an endogenous peptide hormone, not typically administered exogenously. However, motilin receptor agonists like erythromycin are used clinically as prokinetics, but their use is limited by side effects. Selective motilin agonists are in development. Dosage information below pertains to research scenarios using motilin analogs or in the context of motilin receptor agonist therapy (e.g., erythromycin).

Standard Dosage Range

Research dosing range: N/A (Motilin itself not administered). Erythromycin: 250-500mg every 6-8 hours.

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Gastroparesis (Erythromycin - off-label)

250-500 mg3-4× daily
Duration

Up to 4 weeks

Erythromycin is a motilin receptor agonist used off-label. Tolerance often develops with long-term use. Side effects are common (GI cramping).

Postoperative Ileus (Research Setting)

N/A (Motilin analogs used in research)N/A
Duration

N/A

Motilin agonists are being researched to aid recovery of GI motility after surgery. Dosage varies significantly in research studies. Not for self-administration.

Small Intestinal Bacterial Overgrowth (SIBO) - Prevention (via MMC stimulation - Erythromycin)

250 mg1-2x daily
Duration

Limited use due to antibiotic resistance concerns

Used with extreme caution and short-term only due to antibiotic resistance risks and side effects.

Timing & Frequency

Erythromycin is typically administered 30-60 minutes before meals to promote gastric emptying. Due to the short half-life of erythromycin, frequent dosing is required.

Cycle Guidance

Cycling is not applicable to motilin itself. For erythromycin, short cycles (e.g., 2-4 weeks) are used to minimize the risk of antibiotic resistance and side effects. Tolerance to the prokinetic effects can develop with prolonged use.

Frequently Asked Questions

What is the dosage of motilin for gastroparesis?
Motilin itself is not typically administered exogenously. Erythromycin, a motilin receptor agonist, is used off-label at a dosage of 250-500 mg, 3-4 times daily. However, this is associated with significant side effects and resistance issues.
Are there any motilin analogs available?
Several motilin analogs are in preclinical and clinical development, but are not currently available for widespread use. Dosage information varies significantly across different analogs in research studies.
Can I take motilin to improve my digestion?
Motilin itself is not available as a supplement. Strategies to naturally stimulate motilin release include intermittent fasting and avoiding late-night eating. Erythromycin should only be used under strict medical supervision due to risks.
