What to Know Before Using Pyrilutamide

Pyrilutamide (KX-826), a pharmaceutical compound designed with a specific therapeutic purpose, has become a subject of growing interest in the medical community. As with any medication, comprehending its nature, applications, and potential implications is very important before considering its use.

Pyrilutamide stands out for its unique properties and targeted applications which include managing specific medical conditions, preventing hair loss, influencing biological processes within the body,  and more. In this post, we will particularly talk about Pyrilutamide and give you the knowledge required before using it so that you can make wise decisions. 

What to Know Before Using Pyrilutamide

Pyrilutamide and Its Primary Uses, with a Focus on Hair Loss

Pyrilutamide (KX-826) is a member of the pharmaceutical family. Pyrilutamide was invented by Kintor Pharmaceutical Limited, a company that is well-known for making innovative solutions for androgen receptor-related diseases like androgenetic alopecia, acne vulgaris, and certain cancers.

Originally developed for its anti-androgenic properties, Pyrilutamide has found significant application in the treatment of conditions influenced by androgen hormones, such as androgenetic alopecia, commonly known as male-pattern baldness.

Androgenetic alopecia, a prevalent form of hair loss, is characterised by a hereditary predisposition to the effects of dihydrotestosterone (DHT) on hair follicles. Pyrilutamide, through its anti-androgenic activity, works by inhibiting the effects of DHT – a hormone implicated in hair loss – thereby slowing down the progression of androgenetic alopecia.

Mechanism of Action

This drug acts as an androgen receptor antagonist, meaning it competes with and inhibits the binding of androgens like DHT to their respective receptors. By interfering with this binding process, Pyrilutamide mitigates the hormonal signals responsible for hair follicle miniaturization and eventual hair loss.

In simpler terms, Pyrilutamide acts as a protective shield for hair follicles and interrupts the chain of events that lead to their gradual deterioration. This mechanism is necessary in the context of androgenetic alopecia. It offers a potential solution for those seeking to retain and regrow their hair.

It is different from the commonly prescribed 5-alpha reductase inhibitors like finasteride and dutasteride. While both types of medications aim to address the impact of androgens on hair follicles, their mechanisms and potential side effects differ significantly.

5-alpha reductase inhibitors, including finasteride and dutasteride, work by preventing the conversion of testosterone to dihydrotestosterone (DHT). This reduction in DHT levels is essential in slowing down or halting the progression of androgenetic alopecia. However, these oral medications come with potential side effects.

Pyrilutamide, on the other hand, takes a unique approach as a topical anti-androgen. Unlike its oral counterparts, Pyrilutamide's clinical trials have shown that it does not lead to a decrease in systemic androgen levels. This is a key differentiator which indicates that Pyrilutamide is less likely to induce the adverse reactions commonly associated with oral 5-alpha reductase inhibitors.

The absence of systemic effects, such as changes in libido and mood, makes Pyrilutamide an intriguing option for those seeking an alternative to oral medications. The focus on topical application not only suggests a different avenue for intervention but also raises hopes for fewer side effects traditionally linked with androgenetic alopecia treatments.

Pyrilutamide Clinical Trials and Medical Indications

In September 2021, a pharmaceutical company named Kintor revealed promising results from its Chinese phase II clinical trial of Pyrilutamide, specifically designed for men grappling with androgenic alopecia, commonly known as male-pattern hair loss. This milestone was marked by success in both efficacy and safety. It is essential to note, however, that despite the positive outcomes, the lack of subsequent publication in scientific journals raises questions about the transparency and scrutiny of these findings.

The clinical trial, involving 120 Chinese men with moderate pattern hair loss symptoms classified under the Norwood-Hamilton scale as IIIv, IV, or V, explored various concentrations and application frequencies of Pyrilutamide. The study included three different options and two control groups:

  • Pyrilutamide 2.5 milligrams (0.25% concentration) applied twice daily.
  • Pyrilutamide 5 milligrams (0.5% concentration) applied once daily.
  • Pyrilutamide 5 milligrams (0.5% concentration) applied twice daily.

According to information presented in a poster for the Annual Meeting of the Chinese Hair Research Society sponsored by the Chinese Society of Dermatology, the study found that the application of 5 milligrams of Pyrilutamide twice a day yielded the most significant improvements in hair growth. After 24 weeks of treatment, this regimen increased hair count by an impressive 22.73 hairs per cm². In comparison, the placebo group's hair count only experienced an increase of 15.34 hairs per cm².

Subsequent press releases from Kintor highlight positive outcomes from Pyrilutamide clinical trials in both female subjects and an American phase II trial for male pattern hair loss. These continuous affirmations of positive results underscore the potential significance of Pyrilutamide in expanding treatment options for individuals grappling with hair loss.

Preferred Method of Administration

Unlike some other medications used for hair loss treatment, Pyrilutamide is not taken orally or through injection. Instead, it is applied directly to the affected areas on the scalp. The choice of a topical application method can have practical advantages. This form of administration may enhance the drug's localized efficacy while reducing the risk of broader side effects commonly associated with oral medications.

How to Use Pyrilutamide for Hair Loss

When it comes to addressing hair loss with Pyrilutamide, the key lies not only in the efficacy of the solution but also in its optimal application. Follow these guidelines for effective and efficient use of Pyrilutamide:

Recommended Dosage:

  • Apply a measured amount of 1ml to 4ml of Pyrilutamide solution to the affected area of the scalp daily.
  • The specific dosage can be adjusted based on individual preferences and the severity of hair loss. 

Timing of Application:

  • Apply the Pyrilutamide solution in the morning.
  • Nighttime application may lead to wastage as a significant portion of the solution can be wiped off the pillow during sleep.

Application Frequency:

  • While some clinical studies have demonstrated the effectiveness of applying Pyrilutamide twice daily (morning and night), the majority of users experience success with only once-daily application in the morning.
  • For individuals with severe hair loss, applying the solution twice daily may offer additional advantages. However, for most users, a single application in the morning is deemed sufficient.

Practical Considerations

  • Make sure the affected area of the scalp is clean and dry before applying Pyrilutamide.
  • The severity of hair loss and individual responses to the treatment can vary. For those with more pronounced hair loss, considering twice-daily application may be beneficial.
  • It's recommended to start with once-daily application and, based on personal observations and preferences, adjust the frequency as needed.

Be Consistent

  • Establish a consistent routine for applying Pyrilutamide. Whether in the morning or evening, choose a time that fits seamlessly into your daily schedule.
  • Consistency in application is essential for maximizing the potential benefits of Pyrilutamide in promoting hair growth.
