    00:01 Let's talk about mast cell inhibitors. We also call them degranulation inhibitors but now we have changed the name to just call them release inhibitor, so you may see one of those three names.

    00:12 Cromolyn is the prototypical agent in this drug class. It is an insoluble chemical and has minimal systemic absorption.

    00:20 It is rarely used now. And eye drop and nasal spray formulations are sometimes used for allergy to weed dust, what is commonly called hay fever.

    00:31 Not terribly effective and we don't really use them clinically either.

    00:35 Let's move on to IgE antibody mediated therapy. I have mentioned this type of therapy before.

    00:43 Monoclonal antibodies are completely changing the entire aspect of medicine.

    00:48 I mentioned some of the monoclonal antibodies in lipid control in my lipid lecture some time ago.

    00:55 IgE antibody mediated treatment like omalizumab is a humanized murine monoclonal antibody.

    01:05 It will bind to the IgE on sensitized mast cells. It prevents activation by asthma trigger antigens.

    01:13 Now, it is really expensive. It's in the tens of thousands of dollars.

    01:19 My gosh, it's really quite effective. These are once a week or once every two week injections.

    01:27 Some of the monoclonal antibodies in other treatment areas such as rheumatoid arthritis are given once every 3 months and we're expecting to see some of these agents come out for asthma that are given more rarely as well.

    01:41 This is a very exciting area of medicine. I can't wait to see what happens.

    01:45 And it's completely changing the way we treat asthma.

    Lectures are good but they can be great if there will be more detail on mode of action.

    I liked it because I learned some keypoints in less time .It usually would have took 3-4 days for me to get all the points but LECTURIO and PRAVIN SHUKLE made it easiler for me . But in my point of veiw there should be more detail about the mode of action and mechanism of drug . I can and will recommend lecturio to my friends and even to pharm D friends.
