Overview
What is this medicine?
Rayos is a delayed-release tablet containing prednisone, a type of corticosteroid. It works by reducing inflammation and suppressing the immune system. This specific formulation is designed to release the medicine about 4 hours after you take it, typically in the evening, so that its effects are strongest in the morning when symptoms like joint stiffness are often at their worst.

Pharmacology
Mechanism of Action
Prednisone is a synthetic glucocorticoid. It exerts its anti-inflammatory and immunosuppressive effects by binding to intracellular glucocorticoid receptors. This complex then translocates to the nucleus, where it modulates gene expression, leading to the synthesis of anti-inflammatory proteins (e.g., lipocortin) and inhibition of pro-inflammatory mediators (e.g., cytokines, prostaglandins, leukotrienes). It also suppresses the migration of polymorphonuclear leukocytes and reverses increased capillary permeability.
Pharmacokinetics
Absorption:
Bioavailability:
Approximately 70-90% (for prednisone, converted to prednisolone)
Tmax:
Approximately 6 hours (range 4-8 hours) after evening administration of Rayos
FoodEffect:
Food does not significantly affect the absorption of Rayos, but administration with food may reduce gastrointestinal upset.
Distribution:
Vd:
Approximately 0.7 L/kg (for prednisone)
ProteinBinding:
Prednisone: ~65% (primarily to albumin and transcortin); Prednisolone: ~90% (primarily to albumin)
CnssPenetration:
Limited (prednisone and prednisolone can cross the blood-brain barrier, but CNS concentrations are lower than plasma)
Elimination:
HalfLife:
Prednisone: 2-3 hours; Prednisolone: 2-4 hours (plasma half-life); Biological half-life is longer (18-36 hours)
Clearance:
Approximately 1.5-2.5 mL/min/kg (for prednisolone)
ExcretionRoute:
Renal (primarily as inactive metabolites)
Unchanged:
Less than 5% (of prednisolone) is excreted unchanged in urine
Pharmacodynamics
OnsetOfAction:
Delayed (due to delayed-release formulation, drug release begins ~4 hours post-ingestion, aiming for morning peak effect)
PeakEffect:
Anti-inflammatory effects are generally observed within hours to days, with the delayed-release formulation designed to provide peak systemic concentrations in the early morning hours to address morning symptoms.
DurationOfAction:
18-36 hours (biological half-life, reflecting duration of anti-inflammatory effect)

Special Patient Groups
Pregnancy
Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. Corticosteroids have been shown to be teratogenic in animals. Human data are limited but suggest a possible association with cleft palate in infants exposed during the first trimester, and adrenal insufficiency in neonates exposed to high doses during pregnancy.
Trimester-Specific Risks:
First Trimester:
Possible increased risk of oral clefts (though human data are inconsistent and limited).
Second Trimester:
Generally considered safer than first or third trimester, but continued monitoring for fetal growth and well-being is advised.
Third Trimester:
Risk of fetal adrenal suppression, requiring monitoring of the neonate for signs of hypoadrenalism (e.g., hypoglycemia, hypotension) and potentially requiring corticosteroid replacement therapy.
Lactation
Prednisone and prednisolone are excreted into breast milk. While generally considered compatible with breastfeeding at low to moderate doses, caution is advised. Monitor the infant for signs of adrenal suppression (e.g., poor weight gain, delayed development) or other adverse effects.
Infant Risk:
Low to moderate risk, depending on dose and duration. High doses or prolonged use may pose a higher risk of infant adrenal suppression or growth inhibition.
Pediatric Use
Rayos (prednisone delayed-release) is not indicated for pediatric use. Corticosteroids in general can cause growth retardation in children and adolescents. If corticosteroids are necessary, the lowest effective dose for the shortest duration should be used, and growth should be carefully monitored.
Geriatric Use
Elderly patients may be at increased risk for adverse effects, including osteoporosis, hypertension, diabetes, and fluid retention. Use the lowest effective dose and monitor closely for adverse reactions.
Clinical Information
Clinical Pearls
- Rayos is specifically designed for evening administration to provide peak prednisone levels in the early morning, targeting morning stiffness and inflammation in conditions like rheumatoid arthritis.
- Patients should be educated on the importance of not crushing, chewing, or splitting the delayed-release tablets.
- Due to immunosuppressive effects, advise patients to avoid exposure to infections and report any signs of illness promptly.
- Long-term corticosteroid use requires careful monitoring for bone density, blood glucose, blood pressure, and ophthalmic changes.
- Always taper corticosteroids gradually to avoid adrenal insufficiency crisis, especially after prolonged therapy.
Alternative Therapies
- Other oral corticosteroids (e.g., prednisone immediate-release, methylprednisolone, dexamethasone)
- Biologic DMARDs (e.g., TNF inhibitors, IL-6 inhibitors, JAK inhibitors for RA)
- Conventional synthetic DMARDs (e.g., methotrexate, sulfasalazine, hydroxychloroquine, leflunomide for RA)
- NSAIDs (for symptomatic relief of inflammation and pain)
