Two surfactant preperations currently available in canada :\n\n1. BLES \n2. Survanta\n\nIndications:\n* Hyaline membrane disease\n* Premature infants at the risk of developing RDS\n* Meconium aspiration syndrome\n* Primary or secondary surfactant deficiency \n  (no clincial trials)\n\nPls Read the article :\nhttp://www.rcp.gov.bc.ca/guidelines/SurfactantJuly2003Final.pdf\n\nI'm not 100% sure if its commercially available in india:\nIts marketed by abbott laboratories in india. Following is their web site with drug information and contact details:\n\nhttp://www.abbott.co.in/Products/Survanta.htm

Give a demonstration of a lung.  Go to the grocery store and by a bunch of grapes on a stem.  Put the bunch in a plastic bag keeping the big main stem extended thru the bag.  You have made a lung once you seal the top of the bag.  grapes are the air sacs, branches the different sized bronchial tubes and the big one can be you trachea.  Good luck.

If you have mucus in your chest, try Mucinex, it's available at Walmart & CVS. Clears your lungs right out.

The American Lung Association sometimes conducts clinics where these are provided but I don't think they do it online.

A good deal depends on the exact nature of the foreign matter.\n\nLarger sized particulates get trapped in the mucus in the nose or back of the throat, and get cleared, usually by being coughed out  Smaller stuff gets to the trachea and bronchi, gets stuck in the mucus, and swept out by the respiratory cilia, where it is cleared by being coughed out.\n\nReally small stuff can get to the bronchioles and the alveoli--they can induce inflammation, or be cleared.  In the alveoli, they're usually engulfed by macrophages and either dissolved or transported to where they get coughed out.\n\nNow, GASEOUS stuff, and microparticulate aerosols can make their way to where they can directly irritate bronchioles and/or alveoli, or possibly even end up absorbed.  Some vapors/gases will produce enough irritation to trigger off asthma.  A well-known compound here is toluene diisothiocyanate, used in the polymer industry for a handful of reactions.  Other things will get absorbed: lead oxide, generated in the brass casting industry when brass is poured (A lot of brass has from 3 to 17% lead; it makes the brass softer, more ductile, and able to melt at a lower temperature.  It also makes the finished object able to be polished to an amazingly beautiful luster.) can be absorbed via the lungs.  That's why the folks pouring molten brass are required to wear protective equipment, or to have equipment to "inhale" the fumes so the workers don't.\n\nThe topic is rather more complex than this--cigarette smoking, for instance, paralyzes the respiratory cilia, complicating the matter tremendously--but this is enough to give you the general flavor of it all.\n\nBottom line: here, as elsewhere with the human body, there is a wide range of possible responses that vary with the foreign irritant, the way its delivered, and the specifics of the person exposed.\n\nSigh, wouldn't it be beautiful if life were simple?

hi jason,\ni have no idea wht you are asking but when you answered my question about liposomes, you said that i could mail you for the specific. i want the specifics but i dont have you e-mail address...a little halp here.\nshreya s

i don't really know about this but i'm fairly sure i can give a better answer than lrisjqoijgjr  \n\nyou could probably use a surfactant to break down the molecular attraction between the water molecules but this would leave pollution through the path of whatever you were using to travel through the water\n\nbut yeah not really practical but better than uingnpds

I am not sure, but I don't think they are available yet.  I am interested in them as well because of the new study that shows they may help people with MS that also use Copaxone.  I'll check.

Chemical laboratory supply houses carry it.  Try Alfa Aesar, they have it:\n\nhttp://www.alfa.com

you use a nebulizer to treat lungs expansion

If you are on home oxygen, following advise from this forum can be dangerous. Please don't try any home remedies, without consulting your physician. \n\nA note to anyone suggesting home remedies for increasing lung capacity. You don't know this persons history, and bad advice can be lethal. Think before you write.

Depends on the disease, or type of disease.  Google the American lung association, they have links to national resources.  Good luck.

No, but boy that would be nice. My son and  I have Astma, but thankfully it's very mild.\n\nNow, I've heard of Athletes who've abused Albutrol to increase their lung functions. (Albutrol is a medication commonly in astmas inhailers)

There are natural surfactants in the water from certain organisms that grow in the ocean (e.g. kelp, coral). The wave action on the water and surfactants then makes the foam.

It's just the technical name for a type of soap.\n\n"Surfactants are active cleansing substances that consist of a fat-soluble (lipophilic) part and a water-soluble (hydrophilic) part. The lipophilic part sticks to oil and dirt, and the hydrophilic part allows it to be washed away. Surfactants may be a soap, a synthetic detergent or a combination The choice of cleaning agent helps determine the product's lathering characteristics, feel on the skin and how easily it rinses off."\n\n"Amphoteric surfactants are both negatively and positively charged to leave a pleasant sensation on the skin and reduce the irritant action of anionic surfactants. An example is cocamido propyl betaine; betaines are derived from sugar beet."  -  from the link

Absolutely not, I work in a pharmacy as an intern (I'm in pharmacy school) and there is absolutely no shortage of albuterol inhalers, and there never will be.  There are many different brand names, and many different manufacturers of the generic.  There are sooo many people with asthma, and those without it who need albuterol.  Do not worry.  If your pharmacy was out of stock it's because they didn't order the proper amount needed at that location.

a novel use for an API in a drug delivery system?  kind of a vague question... but you could use the example of inhaled insulin.  it is an API (insulin) and it is in a novel delivery system (inhaler) as opposed to injections.  Generally, a novel drug system could be some kind of cancer drug in a nanoparticle or liposome that will target the cancer area.
