Hello and welcome to Healthcare Magic. Thanks for your query.

According to the information which is advertised, Drizilen and Soliden also contain "natural" ingredients which are secretive and trademarked.

The proposed mechanism of action of Drizilen is a increasing the release of "nitric oxide", which in turn is a vasodilator and improves blood circulation to the penis. It also supposedly promotes the production of testosterone in the body through the use of an ingredient called protodiscin. Now, nitric oxide is indeed a local vasodilator which can improve blood flow, but it would be interesting to note that this is exactly the same mechanism of action of allopathic mediaction like Viagra (Sildenafil), Cialis (Tadalafil).

Solidilin supposedly contains "L-Dopa", which is a precursor to the production of the neurotransmitter Dopamine in the body. So, it is claimed that this mechanism increases the sexual motivation and experience of sexual pleasure. Interestingly again, allopathic medication which increase Dopamine have been proven to improve sexual drive.

So, the supposed "scientific basis" which is proposed is just a replica of the scientific basis of allopathic medication commonly used for sexual problems. This may seem superficially convincing and "scientific". But exactly how these "natural" ingredients have exactly the same effects as the allopathic medication is not made known. Nobody knows if they actually contain these allopathic medication as ingredients or whether they are something else.

In medical practise, the principles are that for any medication safety has to be proven. Secondly,the efficacy of the medication has to be proven. Thirdly, they have to be scientifically tested rigorously and methodically in laboratory, then animals, then healthy volunteers and then patients. Only after all these stages are passed and the medication is proven beneficial and not XXXXXXX they are approved. But as far as these "herbal" or "natural" supplements are concerned, there are no such guidelines or proper scientific methods or evidence. They are marketed just at their face value. So, though there may be "scientific" claims, there is no way to be sure that they are not XXXXXXX

Now, heaviness of the head, headache or mild light-headedness is a common side effect of nitic oxide enhancing (vasodilator) medication like Sildenafil, Tadalafil, etc. So, if the claims of mechanism of action of Drizilen is true, then this could be a reason for your symptoms. However, there is no way this can be confirmed.

My advise to patients is to generally avoid medication where the ingredients are not made known to the user and kept secretive, as there can be unpredictable side effects or allergies in some persons.

Hello again and thanks for writing in.

Unfortunately, laboratories do not do this kind of testing routinely. Moreover, this can be very laborious and terrible expensive to do this kind of testing even in drug or pharmaceutical research companies. In other words, this is not a practical option.
