Abstract:
Osteoporosis (OP) is a degenerative bone disease characterized by decreased bone mass and deterioration of bone tissue microstructure, which increases skeletal fragility and the risk of fractures. Currently, the drugs used clinically to treat OP are primarily classified into two types: bone resorption inhibitors and bone formation promoters. Although they demonstrate certain efficacy, most anti-OP medications do not specifically target bone tissue and may produce significant side effects. In recent years, bone-targeted therapies nano-drug delivery systems (NDDSs) for OP have gained attention due to their high drug loading capacity, strong targeting ability, ease of modification, and good biocompatibility. These characteristics effectively address the limitations of traditional therapies and have been widely applied in the treatment of OP. Therefore, this article systematically summarizes recent applications of NDDSs (including inorganic, organic, biogenic, and hybrid systems) in the treatment of OP, focusing on targeting design strategies, in vitro and in vivo efficacy validation, and clinical translation challenges, aiming to provide theoretical references for the development of the next generation of targeted nanomedicines.
Insights
Nano-drug delivery systems (NDDSs) offer targeted osteoporosis (OP) treatment, overcoming side effects of traditional drugs. This review covers NDDS strategies and efficacy for next-generation OP nanomedicines.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Pharmacology
Background:
- Osteoporosis (OP) is a bone disease causing fragility and fractures.
- Current OP drugs have limitations, including off-target effects and side effects.
- Nano-drug delivery systems (NDDSs) show promise for targeted OP therapy.
Purpose of the Study:
- To systematically review recent applications of NDDSs in osteoporosis treatment.
- To focus on targeting strategies, efficacy validation, and clinical translation of NDDSs for OP.
- To provide insights for developing next-generation targeted nanomedicines for OP.
Main Methods:
- Review of inorganic, organic, biogenic, and hybrid NDDSs for OP treatment.
- Analysis of targeting design strategies in NDDSs for OP.
- Evaluation of in vitro and in vivo efficacy of NDDSs in OP models.
Main Results:

Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
