title: [The therapeutic efficacy for ED patients treated with low dosage of PGE1].
abstract: OBJECTIVE
  To evaluate the efficacy of intrameatal application of low dosage alprostadil (PGE1) cream (300 mcg) for the treatment of erectile dysfunction (ED).
  
  
  METHODS
  A total of 43 ED patients were selected in the study based on the inclusion criteria. All of the patients signed informed consent forms and entered a 4-week open-label clinical study. A dosage of 300 mg PGE1 in 75 mg cream was applied intrameatally.
  
  
  RESULTS
  The results showed that the primary efficacy (IIEF Q3 + Q4) reached 70.73% after application of the cream. The successful intercourse rate was 86.41%. Based on the GAQ (global assessment Question); 73.17% of the patients were satisfied with their sexual life. At the same time, all of the secondary criteria supported the primary efficacy results. Two patients withdrew during the study period. Six patients (14.63%) had urethral pain or penile redness, which were mostly mild and transient.
  
  
  CONCLUSIONS
  With intrameatal low dosage (300 mcg PGE1) of the PGE1 cream can achieve an equivalent efficacy as that with the full dosage.
