Calcium and Ibandronate: what the published research says

PubMed indexes 7 records that name Calcium and Ibandronate together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Calcium and Ibandronate. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

7 studies naming Calcium and Ibandronate.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Therapeutic agents for disorders of bone and calcium metabolism: Ibandronate

Clinical calcium · 2007 · PMID 17211088

ReviewHuman subjects

“ibandronate injections effectively reduce bone turnover and increase BMD in Japanese women with osteoporosis. Ibandronate injections provide a new option for the treatment of osteoporosis.”

Hashimoto · From the abstract

Names both Calcium and Ibandronate in its title.

A semimechanistic and mechanistic population PK-PD model for biomarker response to ibandronate, a new bisphosphonate for the treatment of osteoporosis.

British journal of clinical pharmacology · 2004 · PMID 15563360

Meta-AnalysisHuman subjects3380 participants

“This validated K-PD model is currently being used to evaluate a range of novel intermittent oral and i.v. ibandronate regimens in an ongoing clinical development programme.”

Pillai et al. · Authors' conclusion

Names Calcium and Ibandronate together in an interaction, co-administration, or pharmacokinetic context.

Is there a role for bisphosphonates in vascular calcification in chronic kidney disease?

Bone · 2021 · PMID 33188959

Observational StudyHuman subjects

“Thus the efficacy of etidronate as treatment for soft tissue calcification brought with it a problematic tendency to cause osteomalacia. In contrast, conventional doses of nitrogen-containing bisphosphonates fail to yield circulating concentrations sufficient to exert direct anti-calcifying effects, at least in patients with good renal function and studies using alendronate and ibandronate have yielded inconsistent vascular outcomes.”

Hildebrand et al. · From the abstract

Names Calcium and Ibandronate together in an interaction, co-administration, or pharmacokinetic context.

Treatment of reduced bone density with ibandronate in dialysis patients.

Journal of nephrology · 2008 · PMID 18651540

Comparative StudyRandomized Controlled Trial

“Calcitriol dosage increased from 1.5 to 1.83 microg/week. In patients with renal osteodystrophy and ESRD, ibandronate significantly increased BMD and decreased bone turnover.”

Bergner et al. · From the abstract

Names Calcium and Ibandronate together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Calcium, Ibandronate, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
