Calcium and Raloxifene: what the published research says

PubMed indexes 5 records that name Calcium and Raloxifene 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 Raloxifene. 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

5 studies naming Calcium and Raloxifene.

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

Raloxifene lowers serum calcium and markers of bone turnover in postmenopausal women with primary hyperparathyroidism.

The Journal of clinical endocrinology and metabolism · 2003 · PMID 12629102

Clinical TrialRandomized Controlled Trial

“Calcium and bone marker changes were therefore similar to those observed with ERT in PHPT. This short-term study suggests that raloxifene may be a useful approach to the treatment of postmenopausal women with mild PHPT.”

Rubin et al. · From the abstract

Names both Calcium and Raloxifene in its title.

Contribution of raloxifene and calcium and vitamin D3 supplementation to the increase of the degree of mineralization of bone in postmenopausal women.

The Journal of clinical endocrinology and metabolism · 2003 · PMID 12970287

Clinical TrialMulticenter StudyRandomized Controlled Trial

“Raloxifene treatment was found to shift the distribution of total bone mineral to higher values of MDMB (RLX60, 29%; RLX120, 8%) with greater heterogeneity, compared with placebo. The profile of MDMB observed in biopsies after treatment with placebo and raloxifene, compared with baseline, closely resembles physiological premenopausal bone.”

Boivin et al. · From the abstract

Names both Calcium and Raloxifene in its title.

Combination teriparatide and raloxifene therapy for postmenopausal osteoporosis: results from a 6-month double-blind placebo-controlled trial.

Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research · 2005 · PMID 16234962

Randomized Controlled Trial

“Combination therapy increased bone formation to a similar degree as teriparatide alone. However, the increase in bone resorption was significantly less and total hip BMD significantly increased for combination therapy compared with teriparatide alone. Combination treatment with raloxifene may thus enhance the bone forming effects of teriparatide.”

Deal et al. · Authors' conclusion

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

Guidelines for drug therapy of postmenopausal osteoporosis

Wiener medizinische Wochenschrift (1946) · 2002 · PMID 12530170

Comparative StudyReviewHuman subjects

“Also, there is good evidence that in women with Calcium and vitamin D deficiency, a combination of Calcium and vitamin D may reduce the risk of non-vertebral fractures. There is no evidence so far that a combination therapy of antiresorptive drugs would result in reduced fracture risk.”

Dimai et al. · From the abstract

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

Raloxifene and estrogen: comparative bone-remodeling kinetics.

The Journal of clinical endocrinology and metabolism · 1997 · PMID 9329380

Clinical TrialComparative StudyRandomized Controlled Trial

“At 31 weeks, remodeling suppression was greater for estrogen than for raloxifene; however, remodeling balance was the same for the two agents. We conclude that raloxifene and estrogen affect the bone remodeling apparatus similarly, and that raloxifene, therefore, is acting on bone as an estrogen agonist.”

Heaney et al. · From the abstract

Names Calcium and Raloxifene 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, Raloxifene, 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.
