Oseltamivir Phosphate for Oral Suspension Uses

                                                                 Oseltamivir Phosphate for Oral Suspension Uses

Oseltamivir phosphate (Oseltamivir phosphate) is often referred to as "Tamiflu" (Tamiflu).  Oseltamivir phosphate is the most commonly used and one of the most effective drugs against avian influenza, H1N1 influenza virus and influenza B virus. Reducing the incidence of influenza complications can also reduce the use of other medicines, and Tamiflu can increase the survival rate of influenza patients by about 37%.
Oseltamivir phosphate also has large side effects, especially for children. And its price is more expensive to take twice a day, 75mg each time, the retail price of medicines is equivalent to 60 yuan per day, and a course of 5 days is equivalent to about 300 yuan. In addition, taking Tamiflu before the flu has no preventive effect on flu.

After oral administration, oseltamivir is rapidly catalyzed by liver and intestinal esterases to be converted to its active metabolite oseltamivir carboxylic acid. The configuration of oseltamivir carboxylic acid is similar to the transition state of neuraminic acid and can compete competitively. Combined with the active site of influenza virus neuraminidase (NA, neu-raminidase, also known as neuraminidase), it is a powerful and highly selective influenza virus NA inhibitor (NAIs), which Mainly by interfering with virus release from infected host cells, thereby reducing the spread of influenza A or B viruses.
