Contraindicated Populations (Must Not Use): Use is strictly contraindicated for patients presenting with an excess of the active components, including Hypercalcaemia, Hypercalciuria, or Hypervitaminosis D. The medicine is also prohibited in individuals with severe renal impairment, a history of Nephrolithiasis (kidney stones), or known hypersensitivity to the active substances or excipients, such as soya or peanut.

Age-Related Eligibility: Use is established for Adults and Older Adults. The high-dose combination product is not intended for use in Children and Adolescents under 18 years of age.

Restricted and Conditional Use: Use is restricted and requires caution in patients with non-severe renal impairment or sarcoidosis, as these groups necessitate regular monitoring of serum calcium and phosphate levels. For pregnant women, use is conditional upon documented deficiency and is subject to a strict maximum daily dose limit defined by official labeling.

What should I know about interactions with other medicines?

The interaction profile for Bonesil D Flas, a combination of Calcium Carbonate and Colecalciferol (Vitamin D3), is defined by specific pharmacokinetic and pharmacodynamic patterns documented in official government regulatory labeling.

Interaction Category Interacting Agents and Official Pattern
Absorption Interference Tetracycline and Quinolone antibiotics: Calcium reduces the absorption and plasma concentration of these antibiotics. Bisphosphonates and Thyroid hormones also have reduced absorption when co-administered.
Mineral Balance Effects Thiazide diuretics: These agents reduce calcium excretion, formally increasing the risk of hypercalcaemia. Cardiac Glycosides: Co-administration increases the risk of cardiac toxicity if hypercalcaemia is present.
Metabolic Alteration Rifampicin, Phenytoin, and Barbiturates: These substances increase the metabolic clearance of the Colecalciferol component, which is documented to reduce its activity.
Food Interaction Oxalic Acid and Phytic Acid (in certain foods) are documented to inhibit calcium absorption and require specific timing separation from administration.

Administration Constraints: Regulatory documents establish specific timing constraints. For agents like tetracyclines, quinolones, bisphosphonates, and certain dietary items, separation windows of two to six hours are formally required to minimize absorption interference. A specific note exists for elderly patients on cardiac glycosides or diuretics, advising the need for enhanced clinical monitoring due to heightened interaction risk. The documented interactions fundamentally define the requirements for dose spacing and monitoring when co-administered with numerous medicinal products.

Mechanism of Action

Bonesil D Flas is composed of calcium carbonate and cholecalciferol (Vitamin D3). Its mechanism of action is mediated by both components, primarily modulating mineral homeostasis.

Calcium Carbonate Mechanism

Calcium carbonate dissociates into ionized calcium ( Ca^2+) in the acidic environment of the stomach. Ca^2+ is then absorbed in the small intestine via active transport, which is dependent on Vitamin D, and via passive diffusion.

Cholecalciferol Mechanism

Cholecalciferol (D3) is a prohormone. It undergoes 25-hydroxylation in the liver to form 25-hydroxyvitamin D3 (calcifediol), which is then transported to the kidney. In the kidney, 1-alpha -hydroxylase catalyzes the formation of the biologically active metabolite, 1,25-dihydroxyvitamin D3 (calcitriol).

Calcitriol acts as a ligand for the nuclear Vitamin D Receptor (VDR), a transcription factor present in various tissues, including the intestine and bone. The calcitriol-VDR complex translocates to the nucleus, binding to Vitamin D response elements (VDREs) on target genes. This gene transcription modulation leads to the increased synthesis of proteins involved in intestinal absorption of calcium and phosphate. In the bone, calcitriol facilitates the mobilization of calcium and phosphate into the systemic circulation by regulating osteoclast activity.

System-Level Consequences

The synergistic actions of exogenous calcium supply and VDR-mediated pathways increase plasma calcium and phosphate concentrations, directly contributing to the systemic modulation of mineral balance.

Recent Clinical Evidence

Research Evidence: Overview of Studies for Bonesil D Flas

This section provides a summary of the available research base for the combination of Calcium Carbonate and Colecalciferol (Vitamin D3). The information describes the structure and findings of research on the combination, consistent with regulatory guidance on evidence presentation. Research describes group patterns and does not determine whether an individual will respond similarly.

Evidence for Supplementation in Bone Health and Osteoporosis Management

Research for this product was evaluated in multiple Randomized Controlled Trials (RCTs) and systematic reviews that explored outcomes related to skeletal structure and exploring outcomes related to combined mineral and vitamin deficiency. The evidence base was studied for the population of people with osteoporosis and those considered at risk for fractures.

Researchers primarily monitored outcomes related to changes in Bone Mineral Density (BMD), a measured factor. Studies also focused on tracking the reported incidence of clinical fractures (such as hip and non-vertebral fractures) and measuring blood levels of the Vitamin D biomarker, serum 25-hydroxyvitamin D [25(OH)D]. These trials included older adults, particularly postmenopausal women, and also focused on patients who were either institutionalized or living independently in the community.

Studies reported measurements of both BMD and the Vitamin D biomarker. Research describes that changes in these physiological indicators were observed in the studies over the defined time periods. Findings were mixed across the entire body of evidence, and the reported patterns often varied depending on the specific characteristics of the populations studied.

Long-Term Studies and Follow-Up Duration

Studies exploring outcomes was observed in trials with follow-up durations that range across the intermediate term, typically lasting from 18 months to over 3 years. While aggregated data may include observations spanning up to seven years, long-term effects are not fully established across the entire evidence base. This means that information regarding the persistence of the outcomes observed over many years is still emerging.

What Remains Uncertain About the Research

One key challenge is the inconsistency of findings across the different clinical trials. Some large trials focusing on community-dwelling adults have reported different outcomes when compared to the aggregated results of meta-analyses, indicating that evidence quality varies across studies. Furthermore, comparative evidence is lacking for many direct comparisons against other specific calcium and Vitamin D supplement formulations. These are limitations that researchers continue to address.
