    The recent decades have seen tremendous progress in the pharmaceutical industry. The complex and large industry is involved in the development, production, and marketing of pharmaceutical drugs, both in the local and the global market. The rising potential for the Indian pharmaceutics manufacturing sector in the global arena continues to benefit industry growth and exports.

    Most of the pharmaceutical drugs manufacturing companies deal with generic and branded medications to be sold domestically or exported to other nations. The current production of drugs includes antibiotics, vitamins, steroids, hormones, and biological products, practically covering the entire range of pharmaceutical formulations required for the healthcare industry.

    In this article today, we will first understand what is meant by pharmaceutical formulations and what different types of pharmaceutical formulations exist.

    What is a Pharmaceutical Formulation?

    A pharmaceutical formulation is an outcome of a complex process in which different chemical substances are combined with active drugs to get the intended medicinal product. The final drug mixture or formulation is the mixture of pharmaceutically accepted active ingredient/s and one or more selected inactive ingredients.

    Pharmaceutical formulations are of different forms and types depending on the need and acceptance. Generally, pharmaceutical formulations are given to patients in different forms such as liquid, solid, or semisolid. There are diverse formulation studies involved in the development of drugs that help to ensure that the final drug is both stable and safe for the patients.

    Types of Pharmaceutical Formulations

    • Solid Formulations

    Most of the orally taken drugs take the form of solid formulations and are incorporated into a capsule or tablet for the convenience of the patients.

    • Tablets: Tablets are normally disc-shaped and are prepared from granulated powder compressed into a tablet shape using suitable machinery. These drugs are added with other binding agents, lubricating material, or even flavors to make it palatable for the patients.


    • Enteric Coated Tablets: Unlike normal tablets that are coated with inert substances for disintegrating in the digestive tract, enteric tablets are coated with a material that does not react with the acidic medium of the digestive tract but disintegrates in the alkaline medium of the intestine.


    • Controlled-Release Tablets: These are designed to release the active chemical ingredient into the body in a specific measure over a specified period of time. There are also sustained-release formulations which release a fixed amount of drug for an extended period of time, thus improving the treatment compliance.


    • Capsules: These can be either hard or soft. Hard capsules contain the drug formulation in solid form while soft capsules contain liquid or semisolid form.


    • Liquid and Semi-Solid Formulations

    Unlike solid formulations that take time to disperse into the body after administration, liquid and semi-solid formulations are more readily absorbed. These pharmaceutical formulations are administered in different ways, such as oral or topical.

    • Oral Preparations

    These formulations are easier to swallow and are generally suggested for children and old-age patients. Some formulations are added with flavorings and sugar to make them more palatable. Most of the oral preparations are available as solutions, emulsions, or suspensions, and must be shaken well before use.

    • Topical Preparations

    Topical preparations are generally administered directly by applying them onto the affected area of the body. Some of the common topical drug formulations are eye drops, nasal drops, ear drops, nebulizers and inhalers, gels, lotions, creams, and ointments.

    • Injections

    These formulations are in a liquid form and are mostly injected directly into the body using injections. They directly enter the bloodstream and bypass the digestive tract to make the drug act faster. There are different types of injections, such as subcutaneous injection, intramuscular injection, and Intravenous injection.

    To effectively prepare a pharmaceutical formulation, it is necessary to gain hands-on education on pre-formulation studies. It is crucial to be able to evaluate and formulate the drugs for their stability and chemical interactions. We, at Indore Institute of Pharmacy, a PCI approved pharmacy college in Indore, understand that pharmaceutical professionals play a crucial role in ensuring good health for the nation and hence make sure that we prepare our pharmacy students with the finest of pharmaceutical education. Our cutting-edge curriculum, eminent faculty, and state-of-the-art infrastructure facilities provide the students with a quality learning experience and comprehensive understanding of the field. Students at IIP are taught and trained with hands-on,industry-centric knowledge and skills to help them become dynamic, competent, and future-ready pharmaceutical professionals.
