Nonsteroidal anti-inflammatory drugs for external use in the treatment of musculoskeletal pain syndromes

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most popular pharmaceutical products. They are prescribed during the treatment of a number of diseases and conditions, often in entire courses. Even with clear instructions from the attending physician, many compatriots have doubts and look for information about drugs on the Internet. And then they come to the pharmacy and ask the pharmacist questions, hoping to justify their guesses or dispel doubts. In this situation, the head manager needs, on the one hand, to help the pharmacy visitor, and on the other hand, not to take on the role of a doctor. It is in this vein that we will cover the topic of topical NSAIDs today - in the form of competent answers to customer questions.

What does “when used correctly” mean? Anointed, and that’s it.

It is advisable to rub in topical forms of NSAIDs for a while rather than just apply them. The analgesic and anti-inflammatory effect of the ointment will be much higher if you do not just “anoint” it, but actively rub the product into the skin over the sore spot for some time. In the course of relevant studies, it was found that even 45 seconds of rubbing diclofenac diethylamine gel five times increased the transdermal delivery of the drug compared to simple application to the skin. And you need to remember that pain-relieving ointments based on NSAIDs act on areas of pain located immediately under the skin. If we talk about joints, then these are the knees, elbows and small joints of the hands. The local form most likely “will not reach the hip joint.” It should be rubbed “around the circumference” of the limb, for example, not only into the dorsum, but also into the palmar surface of the interphalangeal joint [6, 7].

Dental antibiotic in adult and pediatric dentistry - features

Antibacterial agents have proven themselves in the treatment of various diseases caused by infections and pathogenic microbes. They are used to eliminate the inflammatory and infectious process in the oral cavity and maxillofacial region, as well as to suppress pathogenic microflora.

This group of drugs is used in the treatment of chronic and acute pathologies (implantation, surgery, periodontology, dentistry).

Dental antibiotics are prescribed for the following complications and infections:

• tooth abscess - an inflammatory process of the roots with abundant accumulation of pus;
• various inflammatory and purulent processes;
• periodontitis – inflammation of connective tissues (periodontal);
• pulpitis - a symptom of advanced caries, which often leads to the destruction of hard tissue;
• before surgery - to prevent inflammatory processes and complications;
• gumboil - gum disease.

In some cases, the drug is prescribed after tooth extraction and for the prevention of dental disease. The effect of the drugs is different. Use: to disrupt the formation of supporting polymers of cell walls, block the actions of microorganism enzymes, accumulation in bone tissue. Antibiotic therapy has also proven itself in pediatric dentistry.

Which topical NSAID is best?

Everything is individual. If the analgesic effect of oral and injectable forms of NSAIDs can be more or less ranked, then an objective comparative assessment of topical drugs is very difficult. The reason for this is that, along with the actual active substance, the intensity of rubbing, excipients (for example, dimethyl sulfoxide) and the placebo effect play a significant role. Most studies on the effectiveness of topical NSAIDs have focused on diclofenac and ketoprofen. The increased attention to them is due to the fact that diclofenac is the only NSAID whose topical forms are approved by the American Food and Drug Administration (FDA), and ketoprofen, accordingly, is approved in most other countries of the world. Reliable data comparing these two drugs with each other have not yet been published. No one questions the effectiveness of other non-steroidal anti-inflammatory drugs for external use (ibuprofen, phenylbutazone, piroxicam, nimesulide, etc.); each of them was the subject of several clinical trials at one time, but the geography of their use is much more modest and is often limited to a few developing countries [2, 8].

Do excipients in the local form of NSAIDs matter?

Yes, they improve skin permeability and perhaps enhance the therapeutic effect in a certain way. In separate studies, for example, topical formulations of diclofenac with dimethyl sulfoxide (DMSO) and diclofenac diethylamine 1.16% have been shown to penetrate the skin faster than “regular” diclofenac sodium gels. In addition, DMSO itself may have a slight anti-inflammatory effect. There is no solid evidence of an increase in the analgesic effect due to the listed supplements, but their use at least helps to overcome the individual characteristics of the skin [7, 9–11].

Commonly used drugs for inflammation

In dentistry, several types of antibiotics are used for toothache and inflammation.

• Penicillin group. Prescribed at any age, with minimal side effects and easy tolerability. The main use is for periodontal inflammation. Effective against anaerobic bacteria.
• Cephalospoirins. They are used when it is necessary to perform dental manipulation with the risk of injury, as well as during periodontal and odontogenic inflammatory processes.
• Tetracyclines. Relieves swelling in the area of ​​bone and soft tissue.
• Imidazole and derivatives. They have a depressing effect on pathogenic microorganisms and quickly penetrate bone tissue. Recommended for extensive inflammatory lesions.
• Macrolides. Used during pregnancy and allergies to drugs of the penicillin group. Eliminates gram-negative and gram-positive bacteria.
• Lincosamides. Do not cause allergies. Used for severe bone tissue infections.

The prescription of osteotropic antibiotics is combined if the tests reveal different types of pathogenic microbes.

Can I take NSAID tablets and use the topical form at the same time?

This is not directly prohibited by the instructions for use, but it is not recommended, and, apparently, does not make sense. According to the only credible study on this topic, there was no significant increase in the analgesic effect when combining local and systemic forms of NSAIDs. At the same time, this use of drugs slightly increased the frequency of rectal bleeding. In clinical trials, oral administration of diclofenac and ibuprofen at doses 2 and 3 times higher than recommended also did not lead to increased pain relief. The effect of a combination of tablets and a topical form of NSAIDs will most likely not be pronounced. At the same time, the likelihood of unwanted reactions slightly increases. Therefore, this combination is not recommended. Usually, if a local remedy does not help, the doctor cancels it and transfers the patient to oral administration [12, 13].

Is it possible to use topical NSAIDs for stomach erosions or ulcers?

According to the instructions, it can be done “with caution.” The concentration of the active substance in the blood plasma after the use of topical NSAIDs is less than 10% of that achieved by oral administration. The incidence of adverse reactions from the gastrointestinal tract when using local forms of NSAIDs does not differ from that when rubbing placebo and is significantly lower than when using systemic agents. However, just in case, these drugs are not recommended to be applied to the skin during gastrointestinal bleeding and exacerbation of gastric or duodenal ulcers [5, 14].

Wound healing and factors influencing this process

The wound healing process can be disrupted by many factors.

Healing is the process of repairing damaged tissue and restoring its integrity. During the healing process, certain processes occur. We will not dwell on them in more detail, but will only indicate those factors that may disrupt the healing process:

• Age. As a rule, this applies more to older people. The child's body has great regenerative capabilities. This is due to the high level of anabolic (construction) processes in the body.
• Attachment of infection.
• Decreased immunity.
• Poor circulation in the wound area.
• Chronic diseases (diseases of the respiratory and cardiovascular systems, diabetes, tumors and others).

Healing complications

1. Attachment of infection . Most often, a nonspecific purulent infection develops. The threat is tetanus, rabies, diphtheria. Therefore, injuries that have been bitten and contaminated with soil or old metal objects should be immediately examined by a surgeon with a number of preventive measures taken (administration of anti-tetanus serum, rabies vaccine).
2. Bleeding.
3. Divergence of defect edges.
4. In some cases, healing may be complicated by a hypertrophic scar or keloid . They are an abnormal scar that can spread beyond the defect area and also contribute to the development of complications.

How many times a day and for how long can you apply such drugs?

Typically three to four times a day for two weeks. Topical NSAIDs act quite quickly - the effect occurs within an hour - and help control acute somatic pain of moderate intensity. They cope worse with chronic pain. If there is no effect within two weeks of proper use, you should consult a doctor. There is a chance that he will recommend switching to oral forms or another group of drugs.

First aid for a child for superficial wounds

When such a situation arises, parents ask themselves: “How to treat the wound? How to properly treat a wound? What is the best remedy for treating a wound?

Before helping a child, parents need to wash their hands with soap and use an antiseptic. Next, in this sequence, you need to follow a number of instructions and actions:

1. Assess the extent and nature of the damage. It is very important to understand whether the baby has a deep or superficial wound.
2. Rinse and stop bleeding. Hydrogen peroxide is best suited for this purpose. You can also use a solution of furatsilin and chlorhexidine.
3. Next, you can treat the skin with a drying antiseptic, for example, iodine solution or brilliant green.
4. Apply an aseptic (clean) dressing.
5. In the future, it is important to change the dressings regularly. It is also possible to use ointments and creams discussed earlier, which will speed up the healing process.

In case of deeper defects, heavy bleeding, wounds that have been bitten and contaminated with soil or old metal, you must urgently contact a surgeon.

Wounds are quite common, especially in young children. The task of parents is to provide timely assistance to the child in order to prevent infection. You must have a minimum first aid kit in your first aid kit. Do not self-medicate and, if threatening injuries occur, consult a doctor.
