Unique among methylxanthines with respect to mechanism of action?
Explanation
Enprofylline is unique among methylxanthines with respect to its mechanism of action because it exhibits both bronchodilator and anti-inflammatory properties. While other methylxanthines primarily act as bronchodilators by relaxing the smooth muscles in the airways, enprofylline also possesses anti-inflammatory effects by inhibiting the release of inflammatory mediators. This dual mechanism of action makes enprofylline a more comprehensive treatment option for respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).Rate this question:

Unique among beta 2 agonist in that it is a prodrug and gets converted by esterase in lung
Explanation
Bitolterol is unique among beta 2 agonists because it is a prodrug, meaning it is inactive in its original form and needs to be converted into an active form in order to have its intended effect. In the case of bitolterol, it gets converted by esterase, an enzyme found in the lungs. This conversion allows bitolterol to exert its bronchodilatory effect, making it distinct from other beta 2 agonists which do not require this activation step.Rate this question:

unique among mast cell stabilisers with additional antihistaminic action
Explanation
Nedocromil is unique among mast cell stabilizers because it also has additional antihistaminic action. This means that it not only prevents the release of histamine from mast cells, but it also directly blocks the effects of histamine on target cells. This dual action makes nedocromil an effective treatment for allergic conditions such as asthma and allergic rhinitis.Rate this question:

Unique among peripherally acting antitussives with respect to use in cough? (drug induced cough)
Explanation
Cromolyn is unique among peripherally acting antitussives because it is primarily used for the treatment of drug-induced cough. While other peripherally acting antitussives may be used for various types of cough, cromolyn specifically targets and alleviates cough caused by medications. This makes it a specialized option for individuals experiencing cough as a side effect of certain drugs.Rate this question:

Drugs used in triple therapy for H.Pylori- it can be one or more
-
Tetracycline
-
Omeprazole
-
Tinidazole
-
Amoxicillin
Correct Answer(s)
A. Omeprazole
A. AmoxicillinExplanation
The correct answer is omeprazole and amoxicillin. Omeprazole is a proton pump inhibitor that reduces the production of stomach acid, which helps in the treatment of H. pylori infection. Amoxicillin is an antibiotic that is effective against H. pylori. These two drugs are commonly used in combination as part of triple therapy for H. pylori eradication. Tetracycline and tinidazole are also used in some cases, but they are not mentioned in the given question.Rate this question:

Drug of choice for hiccups
Correct Answer(s)
chlorpromazineExplanation
Chlorpromazine is the drug of choice for treating hiccups. Hiccups are caused by involuntary contractions of the diaphragm muscle, and chlorpromazine helps to relax the diaphragm and reduce the frequency and intensity of hiccups. It is an antipsychotic medication that also has antiemetic properties, making it effective in treating hiccups. Other medications like baclofen and metoclopramide can also be used, but chlorpromazine is often preferred due to its effectiveness and safety profile.Rate this question:

Most common side effect of sucralfate
Correct Answer(s)
constipationExplanation
Sucralfate is a medication commonly used to treat ulcers and other gastrointestinal conditions. One of the most frequently reported side effects of sucralfate is constipation. This occurs because sucralfate works by forming a protective coating over the lining of the stomach and intestines, which can slow down the movement of food and waste through the digestive system. As a result, individuals taking sucralfate may experience difficulty passing stools, leading to constipation. It is important for patients to stay hydrated and consume a fiber-rich diet to help alleviate this side effect.Rate this question:

This drug used in peptic ulcer precipitates reyes syndrome
Correct Answer(s)
bismuth subsalicylateExplanation
Bismuth subsalicylate is a drug commonly used to treat peptic ulcers. However, it can also precipitate Reyes syndrome, a rare but serious condition that primarily affects children and teenagers recovering from a viral infection, such as the flu or chickenpox. Reyes syndrome causes swelling in the liver and brain, leading to symptoms like vomiting, confusion, and seizures. Therefore, caution should be exercised when administering bismuth subsalicylate to patients at risk of developing Reyes syndrome.Rate this question:
