What Are Cholecalciferol Capsules USP 60000 IU?

Cholecalciferol capsules USP 60000 IU contain Vitamin D3 (cholecalciferol) in a high-strength oral dosage form. Vitamin D3 is a fat-soluble vitamin essential for calcium absorption, bone mineralization, muscle function, and immune regulation.

The term USP (United States Pharmacopeia) indicates that the active ingredient meets recognized standards for identity, purity, strength, and quality.

A 60000 IU dose is classified as a therapeutic high-dose regimen, typically prescribed for correcting vitamin D deficiency rather than routine daily supplementation.

Why Vitamin D Deficiency Is a Major Health Concern

Vitamin D deficiency is now recognized as a public health issue, even in sun-rich countries like India.

According to studies cited by the Indian Council of Medical Research (ICMR) and WHO, a large percentage of the Indian population has suboptimal vitamin D levels due to:

• Limited sun exposure
• Urban lifestyles
• Skin pigmentation reducing vitamin D synthesis
• Low dietary intake

Vitamin D plays a critical role in:

• Bone strength and calcium metabolism
• Prevention of osteomalacia and osteoporosis
• Muscle function and fall prevention
• Immune system regulation

Composition and Pharmacological Classification

Active Ingredient

• Cholecalciferol (Vitamin D3) – 60000 IU

Pharmacological Class

• Fat-soluble vitamin
• Vitamin D analog

Vitamin D3 (cholecalciferol) is the natural form of vitamin D synthesized in human skin upon exposure to sunlight and is considered more effective than vitamin D2 for raising serum vitamin D levels.

How Cholecalciferol Works in the Body

After ingestion, cholecalciferol undergoes two activation steps:

1. Liver conversion to 25-hydroxyvitamin D (calcidiol)
2. Kidney conversion to 1,25-dihydroxyvitamin D (calcitriol), the active form

Active vitamin D:

• Enhances intestinal calcium and phosphorus absorption
• Regulates bone remodeling
• Supports neuromuscular and immune function

Without adequate vitamin D, calcium absorption drops significantly, even if dietary intake is sufficient.

Why 60000 IU Is Prescribed

A common question patients ask is why doctors prescribe 60000 IU instead of daily low-dose vitamin D.

Clinical Rationale:

• Faster correction of deficiency
• Improved patient compliance (weekly or monthly dosing)
• Better serum vitamin D normalization

Typical prescribing patterns involve:

• Once weekly for 6–8 weeks (deficiency correction)
• Followed by maintenance dosing as advised

Important: Actual dosage and duration must always be determined by a physician based on blood levels and clinical condition.

Drug Interactions to Consider

Although cholecalciferol capsules USP 60000 IU are generally safe when used as prescribed, vitamin D is an active biological compound, not an inert supplement. At therapeutic doses, especially 60000 IU regimens, certain drug interactions become clinically relevant and should be considered by healthcare professionals.

Understanding these interactions is important to ensure optimal efficacy and avoid adverse effects, particularly in patients on long-term medications or with chronic conditions.

---

1️⃣ Thiazide Diuretics (e.g., Hydrochlorothiazide)

Thiazide diuretics reduce urinary calcium excretion. When combined with high-dose vitamin D supplementation:

• Risk of hypercalcemia may increase
• Serum calcium levels may rise excessively

This interaction is particularly relevant in elderly patients or those receiving vitamin D for osteoporosis or deficiency correction.

👉 Clinical relevance: Monitoring calcium levels is recommended when cholecalciferol capsules USP 60000 IU are prescribed alongside thiazide diuretics.

---

2️⃣ Corticosteroids (e.g., Prednisolone)

Long-term corticosteroid therapy can:

• Reduce vitamin D metabolism
• Decrease calcium absorption
• Increase bone demineralization

As a result, patients on steroids may require higher or prolonged vitamin D supplementation to achieve adequate serum levels.

👉 Clinical insight: In such cases, consistent-quality formulations—such as softgel capsules with reliable bioavailability—are preferred to ensure predictable absorption.

---

3️⃣ Anticonvulsants (e.g., Phenytoin, Carbamazepine)

Certain antiepileptic drugs induce hepatic enzymes that accelerate vitamin D metabolism, leading to:

• Reduced serum vitamin D levels
• Increased risk of osteomalacia and bone loss

Patients with epilepsy are therefore at higher risk of vitamin D deficiency and often require therapeutic-dose supplementation, including 60000 IU regimens.

👉 Clinical implication: Regular monitoring of vitamin D levels is advised in patients receiving enzyme-inducing anticonvulsants.

---

4️⃣ Cholestyramine and Other Fat Absorption Inhibitors

Drugs that interfere with fat absorption—such as cholestyramine—can significantly reduce the absorption of fat-soluble vitamins, including vitamin D3.

This may lead to:

• Reduced therapeutic response
• Inadequate correction of deficiency

👉 Practical consideration: Administering cholecalciferol capsules USP 60000 IU at a different time from such agents may help improve absorption.

---

5️⃣ Cardiac Glycosides (e.g., Digoxin)

Excess vitamin D can increase calcium levels, which may enhance the effects of cardiac glycosides and increase the risk of arrhythmias.

👉 Clinical caution: Patients receiving digoxin should use high-dose vitamin D only under strict medical supervision, with calcium monitoring when necessary.

---

6️⃣ Calcium Supplements and Combination Therapy

Vitamin D is often prescribed alongside calcium supplements to improve bone mineralization. While this combination is clinically beneficial, excessive intake of both can increase the risk of:

• Hypercalcemia
• Renal complications

👉 Best practice: Combination therapy should be dose-balanced and monitored, especially when using weekly 60000 IU regimens.
