This paper reviewed the safety and tolerability of vardenafil in the treatment of erectile dysfunction (ED), including the general, cardiovascular and ocular safety. Results from clinical trials and practice experience demonstrated that vadenafil had good safety and tolerability, whether for general ED population or for difficult-to-treat ED patients, whether as short-term treatment or as long-term therapy.

OBJECTIVETo study the effect and safety of aripiprazole in the treatment of childhood autism.

METHODSThirty-five children (aged from 4 to 16 years) with autism presenting as behavioral disorders were treated with aripiprazole for 8 weeks. They were evaluated according to the Clinical Global Impression (CGI) and the Autism Treatment Evaluation Checklist (ATEC) before treatment and at the end of the 2nd, 4th and 8th weeks of treatment. Adverse reactions were observed.

RESULTSThe CGI showed illness severity decreased from the second week of aripiprazole treatment (P<0.05) and more significantly decreased illness severity was observed at the end of the 8th week (P<0.01). The curative effect score significantly increased at the end of the 8th week (P<0.05). The ATEC total scores were significantly reduced at the end of the 8th week after aripiprazole treatment. Besides the social intercourse ability, great improvements were shown in verbal communication, apperception and behavioural symptoms after aripiprazole treatment (P<0.01). Self-harm, sleep disorders and psychiatric symptoms were greatly improved after treatment and attention deficit, excessive activities, impulse to attack behavior, stereotyped behaviors and irritability were also improved to some extent. No severe adverse effects were found.

CONCLUSIONSAripiprazole is safe and effective for the treatment of childhood autism.

Erectile dysfunction (ED) is one of the most popular and disturbing sexual problems, which impairs patients' health and affects their quality of life. Sildenafil citrate, the first oral PDE-5 inhibitor in the world, has established its efficacy and safety credit in both doctors and ED patients. The authors reviewed the results of related studies in the last decade and made deeper insights into the use of sildenafil citrate in such aspects as the general drug tolerance and its influence on the cardiovascular system, potentiality of concomitant diseases with co-administration of other drugs, long-term safety, and ocular and genital safety.

Phosphodiesterase 5 inhibitors are recommended as first-line treatment of erectile dysfunction in many guidelines, because of their convenience, higher efficacy, and less side-effects. Since its first launch in 1998, sildenafil has been currently the best investigated phosphodiesterase 5 inhibitor with respect to long-term trails and quantity. Clinical trials showed the efficacy of sildenafil compared with placebo in many of the groups of patients who have ED, including those with cardiovascular disease, diabetes mellitus, depression, radical prostatectomy and dialysis. Typically the adverse effects reported in patients from clinical trials of sildenafil have been mild to moderate, and commonly include flushing and dyspepsia and transient visual disturbances. This article summarized recent reports on efficacy and safety of phosphodiesters 5 inhibitors in the treatment of erectile dysfunction.

Erectile dysfunction is a common ailment in middle-aged and old men. The management of ED has entered a new stage since sildenafil was used to treat ED in 1998. Sildenafil became the first-line treatment for its efficacy and safety. In recent years, new PDE5 inhibitors--vardenafil and tadalafil came into market in succession, providing more options available for oral therapy. This review is about the development of preclinical and clinical medicine research on the three PDE5 inhibitors, and provide information for clinical choices.

OBJECTIVETo observe the clinical efficacy and safety of sildenafil in the treatment of high altitude heart disease associated with severe pulmonary arterial hypertension (PAH) in children.

METHODSFifty children (aged 2 months to 2 years) with high altitude heart disease associated with severe PAH, who were continuously transferred to the Intensive Care Unit between January 2011 and October 2013, were randomly assigned to observation and control groups. The control group was given conventional treatment, while the observation group received oral sildenafil [1 mg/(kg . d)] three times daily for 7-10 days in addition to the conventional treatment. Before and after treatment, hemodynamics, blood gas, routine blood parameters, and blood biochemical parameters were recorded.

RESULTSAfter treatment, the observation group had a significantly higher decrease in mean pulmonary artery pressure and significantly higher increases in arterial partial pressure of oxygen, cardiac output, cardiac index, and oxygenation index compared with the control group (P<0.05). In the observation group, there were no significant changes in mean arterial pressure, routine blood parameters and blood biochemical parameters (P>0.05), and no obvious adverse reactions were found.

CONCLUSIONSFor children with high altitude heart disease associated with severe PAH, sildenafil can effectively reduce pulmonary artery pressure and improve cardiac function and does not cause adverse reactions. This therapy has good safety according to the preliminary evaluation.

Since the worldwide introduction of sildenafil in 1998, 23 million patients with ED have been treated with the drug, and the accumulated experiences have proved its safety and efficacy. This article presents a review about the action mechanism and metabolic process of sildenafil, with a particular focus on the application of sildenafil to ED diagnosis, the curative effect of its daily use on ED, the standard treatment, combined therapy and progressive protocol with sildenafil for ED and its complications, along with such safety aspect as its effect on the sight.

OBJECTIVETo evaluate the efficacy and safety of aripiprazole in the treatment of tic disorder when tiapride is used as a control.

METHODSSixty-five children aged 6-14 years old with tic disorders were randomly assigned to two groups: aripiprazole (2.5-10 mg/d) and tiapride treatment (25- 400 mg/d). After 12 weeks treatment, the clinical efficacy was assessed by the Yale Global Tie Severity Scale (YGTSS) score and the adverse reactions were observed.

RESULTSThe YGTSS score in both groups decreased from the second week of treatment. Compared with the tiapride treatment group, the aripirazole treatment group showed a more decreased YGTSS score (29+/-13)% vs (16+/-14)%; P<0.01 by the second week of treatment. The overall effective rate in the aripiprazole and tiapride treatment groups was 91% and 84%, respectively (P>0.05) 12 weeks after treatment. There were no significant differences in the incidence of adverse reactions between the aripiprazole and tiapride treatment groups and no severe adverse events were found in either group.

CONCLUSIONSLow dose aripiprazole is safe and effective for treatment of tic disorders in children, suggesting that it represents a new valid option for the treatment of tic disorder.
