1Medical Service Center of Family Planning of Hanzhong District, Hanzhong, Shan'xi 723000, China.
Objectives:
To supply clinical data for drug selextion in the treatment of erectile dysfunction through intracavernosal injection.
Methods:
Fifty-six ED patients were randomly classified into 2 groups and received phentolamine along with papaverine (for group 1) or phentolamine, papaverine and ligustrazin hydrochloride(for group 2).
Results:
Patients in group 2 enjoyed a longer time of erection. More patients in group 2 succeeded in having enough erection time and hardness to complete sexual intercourse (P < 0.05).
Conclusions:
The extrainjection of ligustrazin hydrochloride injection can help prolong erection duration and hardness and reduce tubercles that might occur in the corpus carvernosal. Therefore it is a safe and inexpensive drug in the intracarvernous injection treatment.
