Prednisone, beclomethasone, cromolyn, and montelukast all must be administered prophylactically to patients with asthma or allergic rhinitis in order for the medications to be maximally efficacious.

Prednisone, beclomethasone, cromolyn, and montelukast all must be administered prophylactically to patients with asthma or allergic rhinitis in order for the medications to be maximally efficacious. However, cromolyn and montelukast can be administered PRN, whereas corticosteroids need to be administered on a fixed schedule (i.e., at the same time each day, regardless of symptoms).

· Why is it that steroids must be administered on a fixed schedule?

· Why is it that long-term use of corticosteroids must be gradually decreased (i.e., tapered) over time, rather than abruptly discontinued?

· How do the side effects of steroids for the treatment of respiratory conditions differ, based on their route of administration (i.e., oral, inhaled, or intranasal)?

Expert Solution

1 . Steroids must be taken at fixed schedule as it will mimicks our own body's production of steroids . Usually taken in the morning hours , it is avoided in the night to prevent insomnia.

2 . Long term usage of corticosteroids should not be abruptly stopped as our body would have needed to produce less steroids when there is extrenal supplementation. This tapering the dose and stopping gives the adrenal cortex chance to regain its function slowly.

3. Side effects of oral corticosteroids :

fluid retention in extremities.
Mood swings
Elevated blood pressure.
Elevated pressure in the eyes.

Side effects of intranasal corticosteroids :

Dryness and irritation in the nasal mucosa.
Nosebleeds.
Unpleasant taste in the mouth.
Nasal bleeds occasionally.

Side effects of inhaled corticosteroids :

Tachycardia.
Weakness
Cough and hoarseness of voice.
Oral thrush.
decreased growth in children in case of long term usage of inhaled corticosteroids.
Decreased immune system.

It is known that 20% of all patients in a medical facility are allergic to a new medication. Doctors conduct a preliminary test to identify patients’ sensitivity to this medication. The test procedure has the following characteristics. • For a patient with no allergic reaction, there is a 10% chance to be misidentified as allergic (false positive). • For a patient with allergy, there is a 5% chance of recognizing this patient as having no allergy (false negative). 1.

A polyhedron must meet three conditions in order to be regular: All of the faces are regular polygons; All of the faces are congruent (identical); All of the vertex points/arrangements are congruent (identical). Try to find three nonregular polyhedra, each of which violates a different one of these conditions. In other words, one of them should meet (1) and (2) but not (3); one should meet (1) and (3), but not (2); one should meet (2) and (3) but not...
