Pharmacokinetics of Singulair (Absorption, Distribution, Metabolism, Excretion)

Singulair, or montelukast sodium, has well-established pharmacokinetic properties that play a crucial role in its therapeutic effectiveness. Understanding how the drug is absorbed, distributed, metabolized, and excreted in the body can provide valuable insights into its mechanism of action and optimal usage.


After oral administration, Singulair tablets are rapidly absorbed from the gastrointestinal tract. The peak plasma concentration is reached approximately 3 to 4 hours after ingestion. Interestingly, the drug’s absorption is not significantly affected by food intake, allowing for flexibility in dosing.


Once absorbed, Singulair extensively binds to plasma proteins, primarily albumin. The extent of protein binding is reported to be high, around 99%. This binding limits its distribution throughout the body, but it is important to note that the drug has demonstrated good penetration into lung tissues, which is crucial for its effectiveness in treating asthma.


The metabolism of Singulair primarily occurs in the liver, where it undergoes minimal biotransformation. The main metabolic pathway involves cytochrome P450 enzyme CYP2C8, with some involvement of CYP3A4. These enzymes convert Singulair into its pharmacologically active metabolite. Despite this metabolic conversion, the overall metabolism of the drug is considered to be relatively low.


Following metabolism, Singulair is primarily excreted through bile, with minimal amounts eliminated in the urine. The drug’s elimination half-life is reported to be approximately 2.7 to 5.5 hours in healthy individuals. It is worth mentioning that in patients with hepatic impairment, the elimination half-life may be prolonged.

7. Pharmacokinetics of Singulair (Absorption, Distribution, Metabolism, Excretion)

Singulair, or montelukast sodium, is a prescription medication used to manage asthma and allergies. Understanding how the drug is absorbed, distributed, metabolized, and excreted within the body can provide valuable insights into its effectiveness and potential side effects.


Upon oral administration, Singulair is efficiently absorbed from the gastrointestinal tract. The maximum concentration of the drug in the blood (peak plasma concentration) is reached within 3 to 4 hours. It is important to note that taking Singulair with food does not significantly impact its absorption, making it convenient for patients to take at any time.


Once absorbed, Singulair quickly distributes throughout the body. The drug exhibits a high degree of plasma protein binding, primarily to albumin. This binding helps ensure that the drug remains in circulation and is delivered to target tissues, including the lungs and airways, where its action is needed.


Singulair undergoes minimal metabolism in the liver, primarily via the cytochrome P450 enzyme system. The main metabolite formed, known as M4, has negligible activity and does not contribute significantly to the therapeutic effects of the drug. This metabolic pathway limits the potential for drug interactions with other medications metabolized by the same enzymes.


The majority of Singulair and its metabolites are eliminated from the body through bile and feces. Only a small portion (less than 1%) is excreted in the urine. As a result, dosage adjustments are not typically necessary for patients with mild to moderate kidney impairment.
