Any Experience with the Use of Vascular Drugs for Circulation (Such as Trental/Pentofixylline)?

Comrades,

Has any of you tried to use in the treatment of tinnitus and in the prevention of spikes, the so-called, vasoactive or vascular drugs?

In particular, I am interested in the experience of using pentoxifylline (Trental). Does anyone have a personal experience?

With some of these drugs, the situation for some reason worsens, but, as a rule, temporarily.
Does it make sense to take such drugs for circulation?
