Механизм действия
Abaloparatid
Abaloparatide is a synthetic analogue of the first 34 amino acids of parathyroid hormone-related protein (PTHrP). Like parathyroid hormone and teriparatide it binds the PTH-1 receptor, but the literature describes it as preferentially engaging the so-called RG conformation of the receptor, which is associated with shorter signaling duration. As for the entire drug class, intermittent receptor activation is regarded as the mechanistic basis for the stimulation of bone-forming osteoblasts observed in studies, whereas continuously elevated exposure would tend to favor bone resorption. From this binding behavior the literature derives a discussed balance between bone formation and bone resorption.
Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight peptides (predominantly below 10 kDa) and free amino acids obtained by enzymatic cleavage of lipid-free porcine brain proteins. The manufacturer and preclinical literature describe a neurotrophic and neuroprotective mode of action said to mimic endogenous neurotrophic factors; cell and animal models have reported effects on neuronal survival, synaptogenesis and anti-apoptotic signalling (including PI3K/Akt). Because it is a complex, incompletely characterised mixture, the precise mechanism in humans remains unclear.

Frequently asked questions
- What is the difference between Abaloparatid and Cerebrolysin?
- Abaloparatid is classified as "Исследования (прочее)", while Cerebrolysin is classified as "Исследования (прочее)". Abaloparatid: Abaloparatide is a synthetic 34-amino-acid analogue of parathyroid hormone-related protein (PTHrP 1-34). It is regulatory-approved and studied in the scientific literature as a bone-anabolic agent for the treatment of osteoporosis in postmenopausal women at high fracture risk. Like the related teriparatide, studies describe it as stimulating new bone formation, but it exhibits a distinct receptor-binding profile. Cerebrolysin: Cerebrolysin (FPF-1070) is not a single peptide but a porcine-brain-derived preparation of low-molecular-weight peptides and free amino acids, produced by standardised enzymatic proteolysis. It is approved in several countries (including Austria, Russia and parts of Asia) for stroke, dementia and traumatic brain injury, but is not FDA-approved in the United States and not centrally approved by the EMA. Its efficacy is contested: Cochrane systematic reviews found no convincing benefit and flagged possible harm signals. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Abaloparatid or Cerebrolysin?
- The highest available evidence level is "РКИ на людях" for Abaloparatid and "РКИ на людях" for Cerebrolysin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Abaloparatid and Cerebrolysin in Germany and the United States?
- Германия: Abaloparatid — Рецептурный, Cerebrolysin — Неясно. США: Abaloparatid — Рецептурный, Cerebrolysin — Не одобрено. These are factual summaries with source and review date on the individual pages.
