China has granted marketing approval of its first drug for the prevention of acute mountain sickness, filling the long-standing gap in the domestic market where no such medications had been available, Science and Technology Daily reported on Tuesday.
The National Medical Products Administration (NMPA) has approved the marketing of acetazolamide sustained-release capsules, the report said. As the first specialized drug in China indicated for preventing of acute mountain sickness, its approval marks the end of the country's lack of dedicated preventive treatment for altitude illness. 
By inhibiting the activity of carbonic anhydrase, acetazolamide promotes the renal excretion of bicarbonate, corrects respiratory alkalosis caused by hypoxia at high altitudes, thereby regulating acid-base balance, optimizing respiratory status, elevating blood oxygen levels, and reducing the risk of onset at the source. 
In contrast to health products that only provide auxiliary regulatory effects, this medication has been validated through stringent clinical trials and stands as a specialized drug approved by the NMPA with a clear indication for prevention, said the report.
Led by principal investigator is Luobu Gesang, a deputy dean of the People's Hospital of Xizang Autonomous Region, the clinical trial was designed by his team and has yielded critical evidence to inform prevention strategies for altitude sickness that are specifically adapted to Chinese and Asian populations. 
"Previously, although acetazolamide had already been used internationally for the prevention of acute mountain sickness, China had long lacked an NMPA-approved acetazolamide formulation supported by rigorous clinical trials. Furthermore, the existing international formulations were short-acting tablets requiring multiple daily doses, and no drugs with the relevant indication were available on the domestic market for an extended period," said Luobu Gesang.
The sustained-release capsule approved this time not only fills this critical gap but also optimizes the dosage form, providing more reliable and convenient medication protection for the physical health and life safety of people entering high-altitude areas, he added.
Clinical trials showed that, compared with the placebo group, the incidence of acute mountain sickness in the medication group was significantly reduced, with the incidence of moderate-to-severe acute mountain sickness decreasing by 14.6 percent, according to the report.
Related research has been published in the international flagship journal of high-altitude medicine, High Altitude Medicine & Biology.

。中央气象台8月7日18时发布台风黄色预警。台风“白海豚”预计7日晚上进入东海，将以每小时10公里到15公里的速度向偏西方向移动，预计9日下午至10日早晨在浙江到福建北部沿海地区登陆，登陆点附近及以北地区将有大范围的风雨影响。据研判，在台风强度上，“白海豚”7日下午强度有所加强，中心附近最大风力由14级增强至15级，接下来强度可能还将增强，有可能达到超强台风级（16级）。不过，“白海豚”在登陆前强度会再度减弱。与7月登陆我国的台风“巴威”相比，“白海豚”的局部风力有可能超过“巴威”，降雨的强度和范围更强、更广，且局地单点降水具有极端性。受台风影响，我省降雨时间长达5天（7日夜里至12日），强降雨主要集中在8日夜里至10日，东部、南部地区累计雨量大，单点有极端性。今天白天沿海地区部分暴雨局地大暴雨，夜里至10日浙中南和沿海地区有暴雨大暴雨，台州、温州和宁波南部局地有特大暴雨；11日浙西地区部分暴雨，局部大暴雨。

C | 再看台风对杭州的影响，预计8日到12日我市有较明显风雨过程，降雨最强时间段集中在9日到10日，过程降水时间长，累计雨量大。今天白天起全市风力逐渐增大，最强时段出现在9日白天到10日上午，最大东北风平原地区8级到10级，山区和江湖水面局地11级以上。目前，“白海豚”正受副热带高压、西风带槽脊、多台风系统等叠加影响，登陆后的移动路径仍存在一定的不确定性。同时，北部湾和西太平洋上分别有热带扰动活动，也将对“白海豚”的发展和移动路径产生一定影响。预计台风登陆后移动路径会趋于明朗，华东及后续可能受到影响的区域应高度重视台风防御，重点防范强风、暴雨及次生灾害。气象专家提醒，台风的潜在影响并不限于移动路径和登陆地点附近，移动路径和登陆点外扩区域同样存在灾害风险。

D | 即使台风深入内陆后中心强度逐渐减弱，强降水也会出现较为分散的分布。在山地迎风坡等特殊地形作用下，有可能会出现局地极端强降水，进而诱发山洪、泥石流等次生灾害。
