April 17, 2014 - FDA approves Ragwitek for short ragweed pollen allergies
2014年4月17日,FDA批准了默沙东(Merck, Sharp & Dohme Corp.)研发的Ragwitek用于治疗短豚草过敏症(花粉热)。该药物是一种短豚草花粉的提取物,在花粉季节到来的12周前开始治疗。Ragwitek经舌下给药,首次治疗需在医护人员监视下进行。临床研究证实Ragwitek可减轻花粉热患者在花粉季节的症状。
Ragwitek contains an extract from short ragweed (Ambrosia artemisiifolia) pollen. It is a tablet that is taken once daily by placing it sublingually, where it rapidly dissolves. Treatment with Ragwitek is started 12 weeks before the start of ragweed pollen season and continued throughout the season. The first dose is taken in a health care professional’s office where the patient is to be observed for at least 30 minutes for potential adverse reactions. After the first dose, patients can take Ragwitek at home.
