Tablet

Tablets are a solid pharmaceutical dosage form. They come in different shapes, such as circles and ovals. Conventional tablets are mainly made of active ingredients. And they also add other stuff, like adhesives or flavorings, to hold the medicine together and make it taste better.

Three Major Types of Tablets in the Pharmacy Industry

Besides regular pills, they also have many different types and forms. The most common ones are as follows.

Coated Tablets

Coated Tablets

This is a type of pill where a special coating is added to the surface. The purpose is to make the medicine more stable, hide any bad smells, and make the pill look better. Some common coated tablets include sugar-coated pills, film-coated pills, and enteric-coated tablets.

Four Differences between Capsules and Tablets

Capsules and tablets are very different. Each has its advantages and disadvantages.

Manufacturing Differences

Capsules get filled up by different machines. The process goes as follows. The capsule filling machines fill the ingredients into the empty capsules with a filling head. Then they seal the capsule body and cap together to make a whole capsule product. Unlike tablets, capsules don't need adhesives during production.

Capsule Filling Machine

Tablets are made through tablet press machines. These machines use pressure to compress powder into tablet shapes. Then they apply enough force to make sure the tablets are stable and of good quality.

Dose Flexibility

Capsules have limits on how much medicine they can hold. If you want to make a big dose capsule, the capsule itself will become big. So it would be harder to swallow.

Tablets have some clear pros in this area. They can hold a larger volume of medicine. If tablets are big, they can also be cut into smaller pieces for taking. Some tablets even have special lines on them to make cutting easier.

Swallowing and Taste Contrasts

Capsules are smooth and easy to swallow. In contrast, tablets might have edges or corners that can stick in your throat or esophagus. It may cause discomfort or make them hard to swallow.

Moreover, capsules can hide the bad taste of the ingredient because of a shell covering. On the other hand, some tablets may have unpleasant or bitter tastes, especially for medicines with strong chemicals or strong smells. Additionally, since the medicine in tablets directly contacts the intestines, it might cause some side effects like stomach or intestinal irritation.

Storage Conditions

The cons of capsules is that they are sensitive to humidity, temperature, and light. They may deform or break when exposed to great changes in heat or humidity.

The storage conditions for tablets are not as strict as for capsules. Just keep them away from moisture, in a cool, dark place.

The End

As two common dosage forms in the medicine industry, capsules and tablets have their pros and cons in different aspects. Capsules are good at hiding the medicine smell and easy to swallow. Tablets are available in a wide range of colors and shapes. Which is better depends on your desired medicine nature and treatment needs.
