Rabusertib by Centre and time from unprotected sexual intercourse to treatment, with allocation concealment by identical opaque boxes labelled with a unique treatment number. participants were masked to treatment assignment whereas investigators were not. Follow-up was done 5-7 days after expected onset of next menses. The primary endpoint was pregnancy rate in women who received emergency contraception within 72 h of unprotected sexual intercourse, with a non-inferiority margin of 1% point difference between groups (limit of 1.6 for odds ratio). Analysis was done on the efficacy-evaluable population, which excluded women lost to follow-up, those aged over 35 years, women with unknown

follow-up pregnancy status, and those who had re-enrolled in the study. Additionally, we undertook a meta-analysis of our BGJ398 ic50 trial and an earlier study to assess the efficacy of ulipristal acetate compared with levonorgestrel. This trial is registered with, number NCT00551616.

Findings In the efficacy-evaluable population, 1696 women received emergency contraception within 72 h of sexual intercourse (ulipristal acetate, n=844; levonorgestrel, n=852). There were 15 pregnancies in the ulipristal acetate group (1.8%, 95% CI 1.0-3.0) and 22 in the levonorgestrel group (2.6%, 1.7-3.9; odds ratio [OR] 0.68, 95% CI 0.35-1.31). In 203 women who received emergency contraception between 72 In and 120 h after sexual intercourse, there were three pregnancies, all of which were in the levonorgestrel group. The most frequent adverse PF299804 clinical trial event was headache (ulipristal acetate, 213 events [19.3%] in 1104 women; levonorgestrel, 211 events [18.9%] in 1117 women). Two serious adverse events were judged possibly related to use of emergency contraception; a case of dizziness in the ulipristal acetate group and a molar pregnancy in the levonorgestrel group. In the meta-analysis

(0-72 h), there were 22 (1.4%) pregnancies in 1617 women in the ulipristal acetate group and 35 (2.2%) in 1625 women in the levonorgestrel group (OR 0.58, 0.33-0.99; p=0.046).

Interpretation Ulipristal acetate provides women and health-care providers with an effective alternative for emergency contraception that can be used up to 5 days after unprotected sexual intercourse.

“5-HT1A receptors mediate some effects of atypical antipsychotic drugs, such as the increase in cortical dopaminergic function, an effect likely related to the superior efficacy of these drugs on negative symptoms and cognitive deficits of schizophrenia. To examine whether 5-HT1A receptors are involved in the therapeutic action of clozapine (Clz) on positive symptoms, here we examined the ability of Clz to antagonize the behavioural syndrome induced by the non-competitive N-methyl-D-aspartate receptor antagonist, MK-801 in wild-type (WT) and 5-HT1A-receptor knockout (KO1A) mice.
