A biconvex tablet is a type of pharmaceutical tablet that has a curved surface on both sides, making it easier to swallow and more efficient in drug delivery. These tablets are commonly used for various medical conditions, including pain relief, infections, cardiovascular diseases, and neurological disorders.
In this topic, we will explore what biconvex tablets are, their benefits, common uses, dosage, side effects, and precautions to help you understand their importance in modern medicine.
What Is a Biconvex Tablet?
A biconvex tablet is a pill that has a rounded, convex shape on both sides, unlike flat or uncoated tablets. This shape provides several advantages, such as:
- Easier swallowing, reducing discomfort for patients.
- Improved drug absorption, allowing the medicine to work effectively.
- Better stability, ensuring the tablet remains intact before use.
- Controlled release, depending on the formulation.
These tablets are commonly used in prescription and over-the-counter medications across various medical fields.

How Biconvex Tablets Work in the Body
The way a biconvex tablet works depends on its active ingredient and formulation. Generally, the process includes:

- Action on Target Organs – The medication travels to the affected area to provide relief or treatment.
- Metabolism and Excretion – The liver metabolizes the drug, and it exits the body through urine or feces.
