Overview of Prostagutt forte

Property Description
Brand Name Prostagutt (often marketed as duo or forte in some regions)
Active Ingredients Saw Palmetto fruit extract, Nettle root extract
Form Oral soft capsule
Pharmacological Class Urological phytotherapeutic agent
Manufacturer / Origin Dr. Willmar Schwabe GmbH & Co.KG (Germany)

Prostagutt forte is a widely recognized herbal medicinal product (phytotherapeutic) used for the symptomatic relief of lower urinary tract symptoms (LUTS) associated with a benignly enlarged prostate gland (BPH). Its formulation is a specific, fixed combination of two proprietary plant extracts, distinguishing it from many single-ingredient herbal medicines. The product is administered as an easy-to-swallow oral soft capsule and is classified as a urological agent.

Products containing Saw Palmetto are traditionally recognized for their role in addressing these urinary difficulties. The medicine is often available without a prescription and is positioned for patients with mild-to-moderate BPH symptoms who seek a well-tolerated, plant-derived option.

Composition and Active Ingredients

The active components in Prostagutt forte are standardized dry extracts derived from the Saw Palmetto fruit (Serenoa repens) and the Stinging Nettle root (Urtica dioica).

The Saw Palmetto extract contains liposterolic compounds thought to affect prostate tissue, while the Nettle root extract provides complementary action, often researched for its anti-inflammatory effects. The extracts are prepared using specific methods to ensure a consistent concentration of active substances, ensuring the product's quality and therapeutic consistency.

Therapeutic Uses of Prostagutt forte

Therapeutic Purpose and Main Uses

Prostagutt forte is a herbal medicinal product used for the relief of lower urinary tract symptoms in men. It is primarily indicated for the treatment of urinary complaints associated with a medically diagnosed benign enlargement of the prostate, a condition known as benign prostatic hyperplasia (BPH).

The preparation is intended to manage the functional symptoms that arise when an enlarged prostate gland puts pressure on the urethra. These symptoms often include:

  • Frequent urge to urinate, particularly during the night (nocturia).
  • A weak or interrupted urinary stream.
  • A feeling of incomplete bladder emptying.
  • Dribbling after urination.
  • Increased frequency of urination during the day.

Benefits and Mechanism of Action

The efficacy of Prostagutt forte is based on the combination of two active herbal extracts: saw palmetto fruit extract (Sabalis serrulata) and nettle root extract (Urticae radix). These components work together to address the underlying inflammatory and proliferative processes in the prostate tissue.

Symptom Management

By targeting the congestion and inflammation within the prostate, the medication helps to reduce the swelling of the gland tissue. This reduction in pressure on the urethra facilitates a smoother flow of urine and can significantly improve the quality of life by reducing the frequency of bathroom visits.

Long-term Support

Regular use of the herbal combination is associated with a steady improvement in voiding symptoms. It is important to note that while the medication treats the symptoms and discomfort caused by the enlargement, it does not reduce the actual size of the prostate gland itself. Instead, it focuses on improving the functional capacity of the urinary system and providing relief from the chronic urge to urinate.

Mechanism of Action

The mechanism of action for Prostagutt forte involves influencing three distinct biological systems within prostate tissue: hormonal pathways, inflammatory cascades, and smooth muscle tone. These coordinated effects influence specific signaling patterns at the cellular level.

Modulation of Dihydrotestosterone (DHT) Signaling

Active components address hormonal pathways central to cell proliferation by modulating the 5-alpha-reductase (5α-R) enzyme, which converts testosterone to DHT. The drug may also interfere with DHT's receptor binding within prostate cells. This targeted pathway interference modulates the proliferation of prostate cells.

Interference with Local Inflammatory Mediators

Components, primarily from the nettle root extract, act on systems where inflammatory mediators dominate. By modulating early molecular steps in the arachidonic acid cascade, the drug limits the production of pro-inflammatory signals like certain prostaglandins. This activity modifies local signaling patterns, influencing factors related to tissue edema and localized inflammatory response.

Influence on Prostatic Smooth Muscle Tone

The mechanism also involves the regulation of smooth muscle activity within the prostate stroma. This action may involve the modulation of alpha1-adrenergic receptors or ion channels, which control the muscle's contractile state. This mechanism influences core physical processes by modulating the contractile state of smooth muscle fibers in the prostate stroma.

Dosage and Administration Information

Administration Protocol

Prostagutt forte is administered via the oral route as a soft capsule. The method and duration of intake are defined by specific application schedules.


Dosage and Frequency

The standard regimen for adults involves taking one soft capsule per dose, establishing a total daily intake of two capsules. This fixed dose contains a specific combination of 160 mg Saw Palmetto fruit extract and 120 mg Nettle root dry extract per capsule. The medicine is taken twice daily, once in the morning and once in the evening, to maintain a consistent dosing pattern.


Administration Conditions and Duration

For proper administration, the soft capsule must be swallowed whole and taken with sufficient liquid, such as a glass of water. Intake is permitted independently of meals (with or without food). The total prescribed daily dosage must not be exceeded.

In terms of duration, use is generally not limited in time, allowing for extended administration. However, a strict age-group administration rule applies: the medicine must not be used in children and adolescents under the age of 18 years.


Handling of Missed Doses

If the administration of a dose is missed, the instruction is to continue taking the medicine as normal at the next scheduled time. Patients are instructed not to take a double dose to compensate for the missed administration.

Recent Clinical Evidence

Prostagutt forte: Recent Clinical Evidence

Clinical research on Prostagutt forte (a combination of Saw Palmetto fruit extract and Stinging Nettle root extract) primarily focuses on its use for Lower Urinary Tract Symptoms (LUTS) associated with Benign Prostatic Hyperplasia (BPH).

Efficacy in Symptom Management

  • Symptom Score Improvement: Several randomized, double-blind clinical trials have investigated the effect of the combination extract on symptoms of BPH. In studies using the International Prostate Symptom Score (I-PSS), treatment with the combination extract was associated with a statistically significant reduction in total I-PSS scores compared to placebo over a 24-week period. Long-term follow-up studies extending to 96 weeks reported that I-PSS scores improved from baseline by a median of up to 9 points.
  • Comparisons to Reference Drugs: In a 60-week randomized, double-blind trial comparing the combination extract to tamsulosin (an alpha-blocker), the median reduction in the I-PSS total score was 9 points in both groups, supporting the conclusion of non-inferiority for the herbal combination relative to the reference drug in this specific trial population.

Other Observed Outcomes

  • Urinary Flow and Residual Volume: Long-term data also included observations related to urinary function. Maximum urinary flow rate and average urinary flow values were found to increase significantly from baseline, while the volume of residual urine decreased significantly over the 96-week follow-up period.
  • Tolerability: Across the randomized and open-label trials, the tolerability of the combination extract was generally reported to be good and comparable to that of placebo.
