Taking Viagra increases hearing and damages the risk
One new research brief on, man to take viagra may increase long-term the intersection of hearing and lost risk.
The result of study reveals, in 11,525 more than 40 years old men, take viagra or other similar function mechanism medicines (are call 5 type phosphoric acid diesterase inhibitor, PDE-5i) Person,it compare as men which does not use medicine on these, report whether there are for twice of the latter on the lost emergences hearing.
One of the researchers, Birmingham institute's epidemiology professor Gerald McGwin of public health of branch school of Alabama university say, the result of study briefs on the U.S. government to lose and use PDE-5i (including viagra, wish to love strength and Ai LiDa hearing at present) Warning correct.
2007, American food medicines administration bureau (FDA) Announce PDE-5i medicine should change labels, in order to reveal the risk of the hearing question more obviously. The reason why took this measure, because several examples used PDE-5i case report related to sudden hearing loss at that time.
Present the job first epidemiology of the relation is studied comment on the intersection of PDE-5i and medicine and long-term hearing, lose. Epidemiology is to study the distribution that the crowd hits disease or health problem and discipline of the possible influence factor.
However, this research only reveals relevance, but can't reveal direct causality, so need to further study to support its result. The research have some defect too, include, use people of medicine these may have a meeting, promote the intersection of hearing and lost factor originally. In addition,this item research institute because of than annual crowd more,actually hearing lost risk.
McGwin says: " Though there is limitation in this research, warn the patient who uses these medicines to take care of physical sign and symptom that hearing damages, and encourage them to seek direct medical science to look after in order to avoid possible permanent damage, this kind of method is cautious. "
Issued in the first stage of magazine of " ENT dept. - surgical file of neck " on May 18 finally.
Do not reach drawing with him (wish to love strength) Or cut down the ground that not (Ai LiDa) Compare, the relevance in the intersection of report and the intersection of person who use the west and non- those (the common name of viagra) Man in the strongest,think McGwin, it is small because of using the sample amount of first two kinds of medicines in part. McGwin said, revealed finally it had increase that he did not reach drawing and cut down strength losses pleasant to the ear of that user of ground, but there is no statistics significance.
PDE-5i medicine was used for treating artery high pressure of lung originally, the function obstacle (ED) of erecting that used for treating extensively now . McGwin says, the more important thing is to study whether really a rational biological mechanism explain how these medicines cause hearing losses.
"PDE-5i medicine can increase particular blood flow that organize in the body and work in the intersection of ED and patient, "McGwin says, " Someone proposes the hypothesis, these medicines have similar function on the similar tissue in the ear, and increasing in blood flow may cause the injury causing hearing to be lost. "
Having reported 29 cases of hearing question from 1996 to 2007, then FDA put forward and wrote the lost warning about hearing exactly on the label of PDE-5i medicine. According to the report, hearing losses take place from several hours to several days after using medicine.
FDA advise use medicine the intersection of person of dysaudia taken place and inactive medicine in the course, get in touch with doctor.
