1. Systemic Procaterol (Meptin) as a CONTROLLER for Asthma
PART 2
Good day to you doctor.
Last time, I was discussing with you the role of Systemic Procaterol (Meptin) as a controller, in treating your patients with asthma. I would like to continue today on the features of Meptin that effectively targets your patient’s symptoms.

2. Treatment Modality for Asthma
Steroids
Anti-inflammatory drugs
Oral/Long acting bronchodilators
Anti-inflammatory effects
Reduce airway hyperreactivity
Sustained bronchodilation
Inflammation
Airway Hyperreactivity
Controller
Bronchoconstriction
Asthmatic attack
Reliever
First let me review with you the treatment modality for Asthma again.
Knowing that the underlying conditions of asthma are inflammation and airway hyperresponsiveness, I hope you will agree with us that bronchodilators having the following features are more recommended as an additional controller to steroids or anti-inflammatory drugs;
1. Anti-inflammatory effect,
2. Reduces airway hyperresponsiveness, and
3. Sustained bronchodilating action.
Inhaled Bronchodilators
Rapid onset of action
Potent bronchodilation

3. Features of Meptin Syrup & Tablets
as A Controller
Long Duration of Bronchodilating Action
Anti-inflammatory Effect
We have tackled last time the Long Duration of Bronchodilating action of Meptin, which showed it longer in action versus other b2-stimulants.
Today let me focus on the 2nd feature: Meptin as a Controller has anti-inflammatory Effect.
Reduces Airway Hyperreactivity

All beta 2 agonists may have an anti-allergic effect theoretically based on the mode of action as shown in this slide.
When adrenergic receptors on the cell membrane of the mast cells are stimulated by beta 2 agonists, an enzyme, adenylate cyclase is activated to convert ATP to cyclic AMP, which facilitates free calcium ions going back to its storage granules in the mast cells, leading to less availability of free calcium ions within the mast cells.
As you know well, doctors, free calcium ions are needed for the mast cells to release chemical mediators such as histamine and luekotriens, since degranulation of the storage granules containing the chemical mediators is calcium ion dependent.
Also, free calcium ions are needed for production of inflammatory substances such as luekotrienes, thromboxane, and prostaglandins in the arachidonic acid metabolism pathway, since an enzyme, phospholipase A2, which is involved in the first step in the pathway, is calcium ion dependent as well.

However, doctors, what is important here is whether such anti-inflammatory effect can be seen at its clinical dose or not.
As you can see in this slide, our product, Procaterol inhibited release of luekotrienes from human lung fragments at its concentration of 10 negative 8 Mol., which is equivalent to the blood concentration of Procaterol when administered to human subjects at its clinical dose of 50 mcg in a single dose. ** * ** ** **

The same results were seen with the inhibitory release of histamine from the human lung fragments at the drug concentration of 10 negative 8 Mol.
From these data, our product, Procaterol, Meptin can exhibit its anti-inflammatory effect at its clinical dose. ** * ** ** ** * ** ** ** ** 10

7. Anti-inflammatory Effects of Meptin
Subjects : Seven Bronchial Asthmatic Children of ages 8-15 （M:4，F:3）
Method : PAF was given ml intradermally.
After 15 min. the wheal area was marked then was covered with a tape.
Meptin tablet 50mcg was administered 2 hrs. before the same procedure was done.

This anti-inflammatory effect of our product, Procaterol, Meptin was also confirmed in a clinical use, as shown in this slide.
In skin test using platelet aggregating factors forming skin wheal as inflammatory reactions, the size of skin wheal was significantly reduced by the administration of Meptin 50 mcg tablets, proving its anti-inflammatory effect at its clinical dose in human subjects.

respectively, before the allergen challenge.

Another possible evidence proving our product, Procaterol, Meptin has anti-inflammatory effect is the data shown in this slide.
In this study, late asthmatic response was inhibited by Meptin tablets as well as Meptin Air.
As you know well, doctors, the late asthmatic response with an allergen exposure normally develop 12 to 20 hours after the exposure to allergens because it takes a longer time, involving inflammatory process.
In spite of the fact that Meptin Air has a duration of bronchodilating action of only 6 to 8 hours, the late asthmatic response was also inhibited by Meptin Air in this study, suggesting that possible reason of this inhibition is not due to its bronchodilating action, but its anti-inflammatory effect.
From these data shown to you, I hope it is now clear to you that our product, Procaterol, Meptin has anti-inflammatory effect at its clinical dose.
