Prostatilen

Prostatilen (Vitaprost/Samprost) represents the clinical pinnacle of targeted male pelvic health algorithms in Eastern Europe. Functioning as a hyper-specific Cytomax bioregulator extracted from youthful bovine prostate tissue, it is a fully authorized pharmaceutical. Used extensively to totally reverse chronic, treatment-resistant prostatitis, aggressively halt Benign Prostatic Hyperplasia (BPH), and violently accelerate tissue repair following severe prostatic surgery.

Mechanism of Action

Prostatilen is a pharmaceutical-grade polypeptide extract derived from the prostate glands of young bulls. Manufactured primarily in Russia and Eastern Europe, it is an injectable therapeutic containing water-soluble peptides with specific tropism (attraction) to the human prostate gland.

It acts by improving prostate microcirculation, reducing tissue edema (swelling), inhibiting leukocyte infiltration (inflammation), and normalizing the secretory function of prostate epithelial cells. It is a widely prescribed clinical treatment in Russia for chronic abacterial prostatitis and benign prostatic hyperplasia (BPH). It works via the same tissue-specific gene regulation pathways as the oral Cytomax version (Libidon), but at a higher, clinical-grade concentration.

Background & History

Prostatilen is one of the earliest and most widely used Khavinson Cytomax preparations, first developed in the 1980s at the Military Medical Academy in Saint Petersburg. It was among the first tissue-specific polypeptide extracts to receive Russian pharmaceutical approval. The preparation is derived from bovine prostate glands using Khavinson's acidic peptide extraction methodology. With over 30 years of clinical use in Russia and CIS countries, Prostatilen has an extensive safety record.

Frequently Asked Questions

How does Prostatilen differ from Libidon?
They are functionally identical in mechanism. Libidon is classed as a food supplement (Cytomax) for oral preventative use. Prostatilen is a much higher concentration, purified extract classified as a prescription medicine for intramuscular injection to treat acute pathology.
