Medications come in many forms, but what we see most of are capsules and tablets, which are the common oral doses. At first look, they may appear very much the same, which is what they are designed for: to put medicine into the body. But in fact their structure, manufacturing processes, release features and ease of use can vary greatly.
I have seen that we as a society tend to use the word “tablet” to describe any solid medicine, which in fact may be a capsule. This may cause issues with prescription understanding and correct medicine use.
What Is a Capsule?
A capsule is a medication that is contained in a shell. The shell is usually made of gelatin, but we also have options of vegetarian and plant-based alternatives. As to what is inside the capsule, it may include powder, granules and other forms of medication.
Capsules as a delivery system have the benefit of the shell, which may mask the taste and smell of the drug, which many find off-putting. Also, the smooth design of the capsule may improve the experience of swallowing for some. Once in the system, the capsule breaks down and dissolves, which in turn releases the drug for it to be fully absorbed.
However, in many cases capsules are more prone to moisture and heat; also, some people may have dietary issues or issues with ingredients, which in turn affect particular capsule shells. Also, it is important to note that not all capsules should be opened. We have some which have very specially designed formulations that require them to stay intact.
What Is a Tablet?
A tablet is what we get when we press together active pharmaceutical ingredients and also other substances known as excipients, which we do to get a solid form. Tablets also come in round, oval, oblong, and other shapes and may or may not be coated.
Tablets are a favourite due to the fact that they are mostly economical, easy to manufacture, simple to package and present in a wide range of strengths. Also, we see which particular tablet is designed for immediate, delayed or extended release of medication.
Certain tablets have score lines which, when the product info or health care provider says it is ok may be broken. Also, some of these are extended-release, enteric-coated, and other special forms of tablets which should not be crushed, chewed or split.
Capsule vs Tablet: Primary Variations.
The main difference between them is in their physical make-up. A capsule has medicine within a shell, and a tablet is a compressed solid dose.
Their dissolution process is what varies. In the case of capsules, the shell has to dissolve first for the content to be released, but with tablets, the body does this, in which the active ingredient breaks apart or dissolves. As per each medicine and form of preparation, the rate of absorption, which may also include how fast the active agent is broken down, also plays a role; it is therefore not right to put forth the claim that one form is better than the other in all cases.
In terms of taste, another difference is between what is taken in capsules and tablets. What is put in capsules is usually in a form to better cover up the medicine, but some tablets may have a very bitter taste, especially when the tablet is chewed, or the tablet’s coating is not sufficient to mask the ingredients.
Cost and also stability may vary. Tablets tend to be a more economic option and have better storage stability; on the other hand, certain capsules require better control of humidity and temperature.
Which One Is Better: Pill form?
There is no one-size-fits-all answer. What works best depends on the medicine type, dose, form of the drug, what the patient needs, and what the doctor or pharmacist says is best. A capsule is not always better than a tablet, and a tablet isn’t guaranteed to be more effective than a capsule.
Some people may have issues with medicine taste, which is why they prefer capsules, and others may find that a certain tablet form is easier to go with. The formulation of the medication is what really matters.
Final Thoughts
Knowing the difference between capsules and tablets is useful, but by far the most important thing is that you take your medication exactly as prescribed. Do not assume that a capsule can be opened up or a tablet can be broken just because it seems safe to do so. Some drugs are designed to release at a specific rate or in a specific part of the digestive system.
If in doubt about how to take a certain pill or tablet, it is best to check with a doctor or pharmacist.
