Kyzatrex is not a 17-alpha-alkyl androgen and is not known to cause hepatic adverse effects.
Kyzatrex, as an
oral testosterone replacement therapy (TRT), offers a distinct approach compared to other TRT options like transdermal patches, intramuscular injections, subcutaneous pellets, and nasal gels. Here's a comparison based on various aspects:
Administration and Absorption
Kyzatrex is a soft gel capsule that you take by mouth. It contains testosterone undecanoate that has been dissolved in a mix of lipids and other solubilizers so that it can be quickly absorbed by the bloodstream while you eat. This formulation allows systemic delivery of
oral testosterone undecanoate via the intestinal lymphatic system, bypassing the liver completely, which is a significant advantage over traditional
oral testosterone therapies that could cause liver toxicity
24. Other TRTs, such as transdermal patches, intramuscular injections, and nasal gels, have their own administration routes, which may not be as convenient for some patients and can cause application site reactions
2.
Efficacy
Clinical studies have shown that
oral TRT, including
Kyzatrex, is effective in maintaining serum testosterone levels within the normal range.
Kyzatrex, in particular, has demonstrated a high efficacy rate, with up to 96% of patients achieving normal testosterone levels within 90 days of treatment. This is comparable to the efficacy rates of other TRT options
3. However, some research indicates that TRT injections might be more effective at increasing muscle strength compared to
oral testosterone3.
Side Effects
Kyzatrex and other oral TRTs have been associated with increased blood pressure, which may lead to heart attack or stroke, among other adverse effects like increased red blood cell count
2. While injectable and transdermal TRTs also share some of these risks, the impact on blood pressure is a notable concern with
oral testosterone undecanoate formulations
67. However,
Kyzatrex has shown a lower risk of hypertension compared to other oral TRTs like Tlando and Jatenzo
3.
Convenience and Patient Preference
Patients typically prefer oral TRTs, such as
Kyzatrex, as an easy method of administration over injections or topical applications, which can be uncomfortable or result in transference problems.
4. The need to take
Kyzatrex with food for effective absorption might be a consideration for some patients
4.
Cost and Insurance Coverage
The cost and insurance coverage for
Kyzatrex compared to other TRTs can vary. While most insurance plans do not cover
oral testosterone as a first-line treatment, there may be options to make oral medication more affordable for patients who cannot use other forms of TRT or have experienced side effects
