目的 總結靜脈制劑Ⅰ期臨床耐受性試驗中的護理要點。方法 2011年10月－12月，采用隨機、盲法、安慰劑平行對照試驗設計，在健康志愿者中按劑量遞增原則，逐組完成8個劑量單次靜脈滴注給藥耐受性試驗。 結果 試驗順利完成。靜脈制劑的Ⅰ期耐受性試驗中，研究護士在臨床試驗前需認真學習試驗方案，做好試驗病房、監護急救設施設備的充分準備，針對可能出現的不良反應制定切實可行的處理預案，試驗過程中密切監測，對出現的不良反應做好救治工作。特別針對靜脈制劑，須做好受試者的心理疏導，保證靜脈穿刺一次成功，減少受試者因情緒緊張、穿刺疼痛等因素干擾對試驗藥物耐受性的評價。 結論 Ⅰ期臨床耐受性試驗實施前準備充分，試驗過程中為受試者提供良好的試驗環境和心理護理，提高靜脈穿刺一次成功率，密切監測，可使試驗過程順利，并獲得客觀、準確的試驗結果。
Objective To evaluate the safety and tolerance of medicinal charcoal enteric-coated tablets in healthy volunteers. Methods A total of 44 healthy volunteers were randomly divided into 6 single-dose groups (0.5 g, 2 g, 4 g, 6 g, 8 g and 10 g) and a multiple-dose group (3 g, 3 times a day, for 14 days). The safety profile and tolerance were evaluated by observing symptoms, vital signs, and laboratory tests. Results No serious adverse event was reported for any volunteer. Abdominal distension occurred in 2 volunteers in the 4 g dose group and the 6 g dose group. One volunteer in the 8 g dose group experienced nausea and vomiting. Transient decrease in white blood cell count was observed in one volunteer in the 10 g dose group. Abdominal distension occurred in 2 volunteers of the multiple-dose group. Conclusion Based on our findings, the maximum tolerated dose of medicinal charcoal enteric-coated tablets in Chinese healthy volunteers is 10 g. The recommended dose for subsequent clinical trials is 3 g, 3 times a day.
Objective To evaluate the clinical efficacy and safety of domestic sparfloxacin in the treatment of acute bacterial infections. Methods A multicenter randomized controlled clinical trial was conducted. 117 patients were treated with domestic sparfloxacin 200-300 mg qd for 5-14 days and 114 patients were treated with domestic lomefloxacin 300 mg bid for 5-14 days. Results The cure rates and the efficacy rates in each group were 84.62%, 74.56% and 94.87%, 92.98%, respectively. The bacterial clearance rates were 94.28% and 92.02%, respectively. Adverse drug reactions rates were 7.69% and 11.40%, most of them were mild. There were no significant differences of above results between the two groups (Pgt;0.05). Conclusions The results suggest that sparfloxacin with wide antibacterial spectrum, satisfactory activity, is an effective and safe antibacterial agent in treatment of mild to moderate acute bacterial infections.
Objective To evaluate the efficacy and safety of amoxicillin/sulbactam (AMX/SBT) in the treatment of acute bacterial infections. Method A multicentre randomized controlled clinical trial was conducted. Ampicillin/sulbactam (AMP/SBT) was chosen as the control drug. 113 patients were enrolled in the study (58 cases in test group and 55 cases in control group). AMX/SUL and AMP/SUL were administered 4.5-6.0 g and 4.5-12.0 g every day respectively. Both drugs were given intravenously for 7-14 days. Results The cure rates and the efficacy rates of the two groups were 75.86%, 80.0% and 94.83%, 98.18% respectively. The β-lactamase producing rates were 67.35% , 69.57% and the bacterial clearance rates were 93.88%, 95.65%.There were no significant differences of the above results between the two groups (Pgt;0.05). There was no serious adverse drug reaction in AMX/SBT groups. Conclusion This study suggests that AMX/SBT is an effective and safe drug for treating acute bacterial infections.
