Methylxanthines inhibit phospodiesterase which is enzyme that degrade cAMP to AMP. Thus lead to an increase in cAMP

Methylxanthines like theophylline work as bronchodilators by inhibiting phosphodiesterase enzymes, particularly phosphodiesterase-4. By blocking these enzymes, methylxanthines prevent the breakdown of cyclic AMP which leads to smooth muscle relaxation in the airways, resulting in bronchodilation and improved airflow.

What is the meaning of mechanism of action in pharmacology?
The mechanism of action in pharmacology refers to how a drug produces its effect in the body at the molecular and cellular level. It explains the specific biological interactions between the drug and its target in the body that result in a therapeutic response. Understanding the mechanism of action is crucial for predicting the drug's effects, potential side effects, and optimizing its clinical use.
What is mechanism of action of ribavirin?
Ribavirin’s mechanism of action is not fully understood, but it is believed to inhibit the replication of RNA and DNA viruses by interfering with their genetic material. It may disrupt viral RNA synthesis and impair viral mRNA capping. Ribavirin has also been shown to have immunomodulatory effects, such as enhancing the activity of natural killer cells.
What is the Difference between pharmacological action and therapeutic action?
Pharmacological action refers to how a drug interacts with the body at a molecular level, while therapeutic action refers to the beneficial effects the drug has on treating a specific condition or symptom in a patient. In other words, pharmacological action is the mechanism of action, while therapeutic action is the desired outcome of the drug in terms of treating a disease or condition.
What is the following fastest mechanism of regulation of acid base balance?
The fastest mechanism of regulating acid-base balance is through the action of the respiratory system. This involves the adjustment of carbon dioxide levels by altering breathing rate and depth to help maintain the pH of the blood within a normal range.
Why do some drugs have narrower spectra than others?
Some drugs target specific receptors or enzymes in the body, leading to a narrower spectrum of activity. Other drugs may have broader activity by interacting with multiple targets in the body. The specificity of a drug's action is often determined by its chemical structure and mechanism of action.
