I'm very very sick. Persistent coughs, DRY COUGHS. Temperatures hitting up to 39.50 degrees Celsius!!! (which is equal to 312.65 Kelvin). I stayed in bed for about 18 hours sleeping, daydreaming, or watching television. Sa madaling sabi, sobrang nakakabagot ang Sunday na iyon. Fever was relapsing. When I stay in bed completely doing nothing, my body temp. stays at around 38 C but when I stand up or watch TV, my temp. rises to about 39 C!!! I had no choice but to bore myself >.< Hey! There was a bright side to this. For one, I've got a whole day doing nothing - no school work or any worries in my head. In fact, I decided not to go to school on the following Monday - more rest! :D Hehe! Good thing I already feel fine this Monday so I can watch TV or surf the net! :D :D Yehey!!! Most of all, more quantity time with my family. For the past few months, I really did have any time for my parents and my younger brother because I really concentrated myself in studies :P. This vacation gave me spend more time with my family. Speaking of coughs, I interested myself in the chemistry of cough syrups. The cough syrup I drank was Robitussin® DM. Here's what I found.....
- There are two types of cough-relievers found in cough medicines: antitussives, or suppressants, and expectorants.
- Antitussives are used in relieving dry coughs wherein the urge to cough out is suppressed.
- Expectorants are used in relieving phlegm-producing coughs wherein mucus in the respiratory tract is loosened so that it can be easily coughed out.
- Robitussin® DM contains two cough-relieving substances: dextromethorphan, and guaifenesin. Dextromethorphan is an antitussive while guaifenesin is an expectorant. These two substances work together not only to relieve cough but also to cure it at some point
