🔬 Mechanism of Action

Prostatilen is a Khavinson Cytomax polypeptide extract derived from bovine prostate glands. Like other Cytomax preparations, it contains tissue-specific short peptides that are proposed to selectively modulate gene expression in prostate cells. The preparation reduces prostatic edema by inhibiting local TNF-α and IL-6 production, normalizes leukocyte infiltration, improves glandular microcirculation, and restores secretory function of prostatic epithelium. In Russian clinical practice, Prostatilen is approved for chronic abacterial prostatitis, benign prostatic hyperplasia (BPH), and post-operative recovery after prostate surgery. Also marketed as Samprost (injectable) and Vitaprost (rectal suppositories with the addition of a fluoroquinolone antibiotic).

📜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.

🎯 Research Use Cases

  • Chronic abacterial prostatitis
  • Benign prostatic hyperplasia
  • Post-prostatectomy recovery
  • Male genitourinary aging

Frequently Asked Questions

Is Prostatilen the same as Samprost?
Prostatilen and Samprost are essentially the same polypeptide extract from bovine prostate, marketed under different brand names. Vitaprost adds a fluoroquinolone antibiotic to the Prostatilen base for treating bacterial prostatitis. All three are Khavinson-era compounds.
