What Are Topical Medicines? What Are Its Types?

Topical medications manufactured by Dermatology Pharmaceutical Companies are creams, ointments, and solutions that are applied directly to your skin. These medications are used for psoriasis include anthralin, corticosteroids, coal tar, retinoids, and vitamin D. Applying these directly to the skin or mucous membrane allows the medicine to enter the body from there. 

They may also be used to nourish the skin and protect it from getting damaged. Some topical medicines are used for local treatment, and some have an effect on the whole body after being absorbed by the skin. 

Pastes, Ointments, and Oils

Pastes are special ointments that contain fat as well as a large number of powder additives. This makes them very thick, and it is difficult to rub them in. One such example is zinc paste. 

Oils are made of fat which is liquid at room temperature. 

They are used as additives for oil baths, as massage oils, or as essential oils, such as lavender oil or peppermint oil. Ointments are mixtures of different fats that can be spread easily. They are made of fat, oil or wax, or a combination of all of these. 

Typical Examples Are Healing Ointments And Fatty Antiseptic Ointments. 

Creams, Lotions, and Foams

Creams are combinations of fat and water that can be spread easily. Because fat and water generally will not readily mix, an emulsifying agent is added to combine these two ingredients and keep them stable, the result of which is also called emulsion. More liquid emulsions on a water basis are called milk or lotions. When air is dispersed in an emulsion, it becomes a topical foam.

Gels, Tinctures, and Powders

Gels are a unique type of water-based cream and are made primarily of thickeners like starch which can bind a lot of water and the active ingredients that are dissolved in it.

Powders are sprinkled on the skin and stick there and can also contain carrier substances (such as talc), in addition to their solid active ingredient. Powders are applied as they have a drying effect and form a film that protects the skin. There are powders for the treatment of itching or fungal infections.

Tinctures are topical medicines in liquid form and are made by dissolving or diluting dried extracts, mostly of plant material. Alcohol is commonly used as a solvent. One example is the tincture of iodine, which is used for disinfecting wounds. Many pharmaceutical organizations outsource their objectives to Clinical Research Organization to get accurate results and also to cut cost expenses. 

Sprays and Patches

Some drugs can be directly applied to the skin or mucous membranes as a spray. There are sprays for disinfection, for treating wounds, or for reducing swelling in the nasal mucous membranes.

Some medications that are supposed to enter the body over a certain period of time can be applied with the help of a patch. A patch can release medicine for a particular period. Just like medicinal patches, there are also hormonal patches and nicotine patches.

This type of application has various advantages:

The medication is absorbed evenly and does not cause any trouble or damage to the gastrointestinal tract. Additionally, patches are convenient and easy to use. These types of patches are also referred to as “transdermal therapeutic systems” (TTS). It is important to take off the old patch before applying the new one, and it is also important to be careful not to stick it in the same place.
