A Regulatory Perspective on Pharmacokinetic/Pharmacodynamic Modelling

The conversation is about using a product containing dutasteride and tamsulosin for hair loss. Users discuss separating the components and potential side effects like frequent urination and changes in libido.

The user has been using finasteride for 3 years with good results and wants to switch to dutasteride combined with tamsulosin. They are seeking more information about tamsulosin.

The conversation discusses using Duodart (dutasteride + tamsulosin) for hair loss, with side effects like frequent urination and ejaculation issues leading to discontinuation. The user switched to German Avodart and experienced mood and erection side effects, considering adjusting the dosage to three times a week.

A dutasteride simulator predicts that daily 0.5 mg dosing results in higher DHT suppression compared to less frequent dosing. Twice-weekly dutasteride may be as effective as finasteride 5 mg, providing a balance between efficacy and ease of use.

The user experienced side effects like watery semen, erection problems, and decreased libido from finasteride, which resolved after stopping it. They are considering dutasteride mesotherapy as an alternative, as advised by their dermatologist, and are concerned about potential side effects.

Concerns about a potential ban on finasteride and dutasteride due to side effects, with users advocating for continued access and informed choice. Alternative treatments like pyrilutamide are also mentioned.
