Tips for Maximizing the Effectiveness of Topical Acne Therapy

Posted on 2, Dec | Posted by Renee

Topical medications are the foundation of therapy for the majority of acne patients. However, use of these products is usually regarded by patients to be time-consuming, difficult, irritating, and comparatively less effective than oralmedications.

Adherence to topical agent use is also compromised by the delay in time to effect, the potential complexity of treatment procedures, and the need to incorporate cosmetics such as foundations, moisturizers, and sunscreen. Although adherence rates to the use of topical acne medications have previously been reported to be as high as 48%-49% [Flanders PA, et al. Behav Res Ther 23:225-7 (1985); Flanders P, et al. J Psychol 118:31-6 (1984)], a recent Canadian observational study of acne patients provided a rate of only 24% (Tan J. unpublished data).

In this group of patients, the most common reasons for poor adherence were absent-mindedness, side-effects, didn’t feel the need, and hassle. Poor adherence to topical acne therapy results in treatment failure, wasted health care resources, and discontent with physician care. This article offers tips to maximize adherence and efficacy of topical acne therapy.

While choosing topical acne products, the following considerations may promote the degree of adherence:

  • convenience of anatomical site for topical therapy (i.e., face, chest and shoulders are accessible; the back is harder to treat)
  • effectiveness
  • acceptability, e.g., facial erythema, irritation, dryness, redness, and scaling
  • cosmetic suitability
  • simple regimen
  • convenience and
  • easy application.

Patients should then be examined at 2-4 weeks to encourage adherence and to check for potential side effects; then every 2-3 months to assess treatment effectiveness.

Types of Treatment Vehicles: With a view to determine the most appropriate topical treatment regime for each patient, physicians must carry out an individualized assessment including disease severity, skin type, formulation availability, patient preference, and considerations like delivery vehicle. Active agents are prepared in a variety of vehicles to sort out the possible combinations.

Normally, patients with drier skin prefer creams for their moisturizing effect while those with an oily skin prefer gels and solutions. The use of foams may be mostly well suited for application to relatively larger regions and hair bearing sites.

Creams are available in oil and water base formulations, tend to be less irritating, help to retain moisture in the skin, are most suitable for patients with dry or sensitive skin, and may result in an oily feel due to thicker consistency.

Lotions can have either water or alcohol base, are the most versatile, can be used for all skin types, can cause skin irritation, e.g., burning and dryness, have a lighter feel, which patients may prefer, and preferred for treatment of large or hairy areas.

Solutions usually contain an alcohol base, which can aggravate dryness and irritation.

Gels contain high water content, are most suitable for oily skin types, have a cooling effect on the face, may leave a surface residue, and tend to cause skin irritation, e.g., burning and dryness.

Foams spread easily, especially helpful if treating larger areas of the body and leave minimal residue on skin surface.

The range of effective topical acne medications can be grouped into the following:

Antibiotics that include Clindamycin, Erythromycin, and Sodium sulfacetamide

Combination Products that include Benzoyl peroxide (BPO) + antibiotic and Topical retinoid + antibiotic and

Retinoids. It includes Adapalene. It is photostable, can be applied in the morning. Tazarotene; It is also photostable, can be applied in the morning. And Tretinoin; It is photolabile, best to apply in evening. Its Micronized version may be less irritating, but is a little more costly.

Compounding Pharmacies and Toenail Fungal options

Posted on 30, Nov | Posted by Renee

Compounding pharmacists continue to improve both the aesthetic and therapeutic aspects of customized medications by offering alternatives and advantages for dermatology. Medications can be compounded into cosmetically appealing creams, topical sprays and powders, as well as create customized oral dosage forms (such as flavored troches or lollipops) and various preparations for other routes of administration. Well-matched drugs can be combined into a single dosage form to make a medication administration schedule simpler and improve compliance. USP approved chemicals can be utilized to increase the absorption of topically applied medications. Generally, physicians prepare unique formulations that are developed to meet specific needs of their patient population, or “tried and true” formulas learnt during medical training.

Head Lice and Scabies

Concerns about emerging resistance and the possible harm of using permethrins have encouraged a search for effective pediculicidal therapies that are safe to children with repeated use. A herbal formulation has been revealed to be effective for head lice. Ivermectin can also be compounded for topical application, or as an oral dosage titrated for each patient for the treatment of head lice and scabies.

Molluscum Contagiosum

The following investigation found that 5% KOH aqueous solution proved to be as helpful and less irritating when compared to the 10% KOH solution. This experiment also emphasizes the effectiveness of topical KOH in the treatment of molluscum contagiosum, sparing those children affected from more aggressive physical modalities of treatment.

Nail Removal

Although surgical removal is the most popular method for removing nails, the use of concentrated urea plasters applied under occlusion may be better. The use of urea plasters has natural advantages – they are reasonably priced, several nails can be treated in one session, and the procedure is almost painless. A variety of synergistic combinations and topical medications with penetrated enhancers can be compounded for antifungal treatment. Topical medications generally have a lower unfavorable drug-reaction profile as compared to the systemic medications.

Onychomycosis

Management of onychomycosis, a fungal infection of the fingernails and toenails, typically consists of systemic antifungal medications, topical therapy (e.g., desiccating solutions, urea ointment, keratolytics, vital dyes), or surgical intercession (e.g., laser therapy, and nail plate avulsion).

Topical prescription antifungal formulations, containing the active ingredient of your choice, may be less liable to cause the serious systemic side-effects that can happen with oral antifungal therapy and can provide a more cost-effective alternative, as lower doses are required when the medication is applied topically at the site.

Penetrated enhancers can be included in the preparation to improve the effectiveness of topical antifungal.

Pigmentation Abnormalities

Patients with vitiligo have high levels of hydrogen peroxide in association with low catalase levels in their epidermis. Topical application of a UVB-activated pseudocatalase cream can effectively remove epidermal H2O2 resulting in an extraordinary re-pigmentation.

Why You May Need A Custom Prescription

Posted on 25, Nov | Posted by Renee

In a world that comprises of so many different people with individual needs and requirements, it is logical that not everyone responds in the same to a given type of medication. Many people suffer from specific conditions that prevent them from taking medicine prepared by traditional methods.

In fact, sometimes the kind of medicine that a particular patient needs is not made by traditional drug companies, or a patient may need to consume the medicine using a different method than the traditionally prescribed one. This is when compounding pharmacies come in to meet the specific needs of the patient.

Compounding pharmacists modify an individual patient’s prescription according to the specific patient needs. There are a number of circumstances that require a discussion with a compounding pharmacist. For example, a patient will need the services of a compound pharmacist if they are not capable to taking ingredients that are included in traditional medicines such as preservatives, alcohol, dyes, sugar, gluten, lactose, and casein.

Patients may also need an alternate way of consuming medicines such as if a patient has trouble swallowing a tablet. Various ways of administering the medicine include: Transdermal such as a skin patch, lozenge, lollipops, creams, nasal spray, liquid form, and inhalation. If a patient is vulnerable to drug side effects or needs reaction free medications, using medication formulated by a compounding pharmacist can considerably reduce the potential side effects and reduce allergic reactions.

If a patient needs a particular dosage that is usually not manufactured by a traditional drug manufacturer, a pharmacist can provide the special dosage to meet the required strength. Patients who are in need of medications that are no longer manufactured by pharmaceutical manufacturers can get the medications from a compounding pharmacist. Also, children who will only take medications that have a pleasant flavour can easily get a specific drug that has a palatable flavour from a compounding pharmacist.

Compounded prescriptions are the best solutions for a patient that needs an alternate route of delivery or a rare dosage. Compounding pharmacists are needed in medical areas such as Bio-identical Hormone Replacement Therapy, Wound Therapy, Sports Medicine, Veterinary practices including both large and small animals, Dental Practices, Hospice, Pediatrics, Infertility, Chronic Pain Management, Ophthalmic, Dermatology, Neurology, Gastroenterology, and many more.

Pharmacy compounding is not just a science of formulating medicines, but is also an art of customizing medications for patients. This type of pharmacy has been around for centuries and is not a new method. However, with increase in the number of patients requiring alternative forms of drugs and with growing innovations in technology and research, there has been an important increase in compounding pharmacies. What’s more, the Food and Drug Administration support the use of compounding and it is regulated by each State’s Board of Pharmacy.

With the approval of a physician, a pharmacist can adapt almost any kind of a medication to make it easier for the patient to consume and have the same effect as traditional manufactured medicine.

Compounding Drugs for Use In Animals

Posted on 23, Nov | Posted by Renee

These days’ people consider their cats, dogs, and other pets as members of their family. For this reason, choosing a veterinarian with an understanding of how important your pet is to you is essential. Actually, the relationship between you, your vet, and your pet should be similar to the relationship you share with your physician. Besides, this relationship should apply to your pet’s medications as well. So buying medicines from a veterinarian that recognizes the value of customer service as it is relates to your pet’s healthcare is of use to both you and your pet.

So how do you define a veterinarian-client-patient relationship? According to the American Veterinary Medical Association, it has been described as follows;

  • The veterinarian must take the responsibility for making medical judgments regarding the health of the animal and the need for a specific medical treatment, and the client must also agree to follow the instructions of the veterinarian.
  • The veterinarian has adequate knowledge of the animal to initiate in any case a general or a preliminary diagnosis of its medical condition. This means that the veterinarian has recently seen and is personally up to date with the keeping and care of the animal by an examination of the animal. This should also include medically suitable and timely visits to the premises where the pets are kept.
  • The practicing veterinarian must be available even at a short notice for follow-up in case of an emergency, an adverse reaction or failure of the treatment.

According to AVMA guidelines, a vet must make all efforts to maintain a positive veterinarian-client-patient relationship before issuing a valid prescription. According to the compounding compliance policy guide (CPG), the section about Compounding of Drugs for Use in Animals, a convincing relationship is compulsory when compounded medicine is prescribed.

This kind of relationship has the potential to serve the best interest of your pet. Besides, this type of an understanding is improved when there is a recommendation from the pharmacist to help authorize the veterinarian. This guarantees that only the best medication is being used in a safest manner for your dear pet.

Dermatology compounding

Posted on 18, Nov | Posted by Renee

No individuals are the same and neither are their allergies or dermatological conditions. The treatment given to them has to be specific to their condition and how it manifests itself in the individual patient. Based on a patient’s specific allergies or dermatologic conditions, special formulations for medications, custom sunscreen, and even makeup are compounded for them. A pharmacist works closely with a patient and their physician to formulate a customized prescription to treat their condition.

No matter what the field of medicine, there would be some patients who don’t respond to traditional methods of treatment. Sometimes they need medicine of very strong potency that is not manufactured by drug companies, or maybe they simply need a different method of consuming a medication.

Dermatology compounding is aimed at meeting all such needs. It provides a systematic approach for physicians and compounding pharmacists to customize an individualized prescription for the specific need of their patient. Dermatology compounding provides solutions which are usually not met by commercial products.

By this time, we are all well aware that compounding or more specifically dermatology compounding is the art and science of preparing customized medications for its patients. Its practice goes back to the origins of pharmacy. Yet, the presence of dermatology compounding in the pharmacy profession has changed in entirety over the last few years.

In the 1930s and 1940s, roughly 60 percent of all medications were compounded. With the introduction of drug manufacturing in the 1950s and 1960s, compounding declined rapidly. The pharmacist’s role as a specialist in formulation of medications quickly changed to that of a distributor of manufactured dosage forms.

However, in the last two decades, compounding has experienced recovery as modern technology, innovative techniques, and research have approved more pharmacists to customize medications to meet specific patient needs.

There are more than a few reasons why dermatologists compound prescription medications. One of the most important reasons is something that the medical community calls as “patient non-compliance.” I’ll explain it in detail to you.

Many patients are sensitive to chemical additions or colorants, or are allergic to standard drug potency. With a physician’s consent, a compounding pharmacist can change the potency of a medication, change its form to make it easier for the patient to consume, or add flavour to improve its taste. The pharmacist also can formulate the medication using some unique delivery systems, such as a sublingual troche or tablet, a lollipop, or a transdermal gel or cream that can be absorbed through the skin. For those patients who find it difficult to swallow a capsule, a compounding pharmacist can alternatively offer him/ her liquid medication.

Compounding pharmacists get the opportunity to work with a variety of specialties, such as hospice, paediatrics, pain management, and OB/GYN, which in turn broaden the scope of their practices and generate other opportunities to provide their services to other pharmacist.

Your pharmacy can easily develop into a compounding pharmacy; one that is committed to offering high quality compounded medications in the dosage form and strength as prescribed by the physician. This relationship between the patient, his/her physician, and the pharmacist is critical to the process of compounding so that all three can work together to work out unique medical problems.

History of Compounding Pharmacies

Posted on 16, Nov | Posted by Renee

All pharmacies were compounding pharmacies before the proliferation of chain drug stores, mega drug stores, and pharmacies in supermarkets, big box stores, and insurance company sponsored mail order pharmaceuticals. The privately owned pharmacies used to have a pharmacist who was known locally by name. Even the local doctors knew him.

Nearly all the human steroid hormones are made available by pharmaceutical manufacturing companies. They are packed in the form of powder and are stocked at the compounding pharmacy. All three estrogens, Estradiol, Estriol and Estrone, are commonly prescribed along with Progesterone, Testosterone and DHEA. Besides, Pregnenolone, melatonin, androstenedione, both thyroid hormones, T-4 and T-3 as well as freeze-dried pork thyroid are also available. Compounding pharmacists also formulate many medicines for dermatological and veterinary use.

There are some compounded products that are easier to formulate when compared with others. The time and effort invested by the pharmacist will be reflected in the price charged to the patient. As a general rule, the hormones themselves, and the fillers or creams, and gels are not that costly. It is the pharmacist’s time that is the main factor in the cost. Some things, like creams, may be just as easy to prepare in a large batch as a small batch. Buying a larger quantity at one time may save the patient a good sum of money. These are all important subjects for both patients and physicians to consider and discuss with their compounding pharmacist.

Let’s look at some of the medication forms available in the market, some of their uses, advantages and disadvantages.

Capsules and Tablets:

Any hormone that can be effectively when taken by mouth can be put in a capsule. Because the quantities of the various hormones are often very small, fillers can be used to fill up the extra space. Some patients may be allergic to, or react poorly to, certain kind of fillers. If such is the case, patients should discuss this with their pharmacist.

There are several types’ available including milk sugar and cellulose. The filler can be varied depending upon the patient’s sensitivity. Although Commercial products also use fillers but neither doctors nor patients have a choice in how they are formulated. Capsules and tablets are easy to consume, travel well, and offer a consistent & reliable dosage.

Oral dosage generally gives more consistent absorption from patient to patient than most other forms. In some cases, if appropriate, a physician can choose the dosage proportions of several different hormones or medications to combine them in a single capsule. This is not only convenient for the patient but also saves money. One disadvantage, however, is that the component parts cannot later be changed separately. It is better to give separate prescriptions until the dose is established and steady for that patient. You can then later combine the medications for convenience and cost saving.

Another minor disadvantage of capsules is that they can only be consumed as one. If you decide to raise or lower the dose, the patient can’t take half or three quarters of a capsule, or a little more than one, whereas in comparison, tablets can be cut and creams or gels can be used in slightly larger or smaller amounts.

Empty capsules are available in a variety of colours. This can be used to differentiate between various medications for ease of the patients tell their apart. At the time of prescribing capsules or tablets, when to administer, whether to consume it with food or on an empty stomach, and dosage frequency must be clearly specified.

There are very few manufacturers that make custom-made tablets. One advantage is that they can be divided for twice a day dosage for the price of one tablet. Multiple doses may be helpful when giving Estradiol or T-3 (triiodothyronine), both of which can be quite rapidly metabolized.

All food and medication taken by mouth, goes through the liver after it is absorbed in the intestine. This is known as the liver first pass effect. For example; Estrogen, has many effects on liver function. As a benefit, estrogen raises good cholesterol (HDL) and lowers bad cholesterol (LDL) when passed through the liver.

On the down side, that same estrogen raises triglycerides and increases blood-clotting reasons. The relative benefits and disadvantages must be considered at the time of deciding upon a route of administration.

Dermatology Defined

Posted on 11, Nov | Posted by Renee

Dermatology is the study of investigating, diagnosing, and treating skin problems of all kinds. Dermatology as a profession is a specialty focusing on various disorders and diseases of the skin, mucous membrane, hair, nails and numerous sexually transmitted diseases.

Dermatology is often practiced in combination with venereology, an area of expertise that diagnoses and treats sexually transmitted diseases, and phlebology, an area that deals with problems of the superficial venous system.

Dermatologists deal with a wide range of diseases including acne, warts, multiple inflammatory dermatomes, skin cancers, autoimmune diseases, occupational dermatomes and contact dermatitis, dealing with these diseases and disorders by way of different investigations and therapies.

Dermatology compounding is an ancient process of mixing drugs by a pharmacist or physician to fit the exclusive needs of a patient. For example, a patient allergic to the dyes used in a pill can take a doctor’s prescription for the necessary medicine to be compounded without the offending dye. Each compounded prescription is hand made from the bets quality chemicals and made by pharmacists that specialize in formulating drugs.

Of all the benefits that dermatology compounding offers, some are as follows
• Avoidance of dyes, preservative, fillers
• Palatable liquid medications
• Administrable dosage forms
• Avoidance of side effects
• Dose, dosage form, or medication not commercially available
• Combination or sustained release therapy to improve compliance
• Cost effective therapy

Here are a few problem solving ideas in cases where a commercially available product might fail to bring about the desired results:

  • Problem Options
  • Acne 4% Niacin amide gel Isotretinoin, Retinoic Acid Benzoyl peroxide, Sulfur, Resorcinol, Erythromycin, Clindamycin, each of the above medications can be compounded into a cream, lotion or gel.
  • Onychomycosis Fluconazole, compounded into a nail polish with DMSO. The DMSO penetrates the nail bed, thus allowing the Fluconazole to work more directly at the site.
  • Bleaching Agents Hydroquinone, Retinoic acid, each can be compounded into a cream, gel or lotion and in combination with lactic or glycolic acids.
  • Eczema Corticosteroidshydrocortisone, Triamcinolone
  • Fever Blisters Acyclovir lip balms, creams, lotions, Deoxy-d-glucose lip, balms, cream and lotions.
  • Psoriasis Corticosteroids hydrocortisone, Triamcinolone, prednisone, Dexamethasone, Betamethasone, oral methotrexate, annthralin, coal tar, resorcinol, sulfur, salicylic acid, most can be compounded into a cream, lotion or gel.

However, any information that you get via books, internet or other media concerning diseases and disorders of the skin cannot be a substitute for a professional medical advice.

Only certified dermatologists have the medical training and experience needed to accurately diagnose the disease and decide on the most appropriate treatments for each patient.

There is an acute need for dermatology training in the world today. Something like 3 billion people living in more than 100 countries need basic care for their skin diseases. For the most part, skin diseases in the world can be detected and successfully treated by simple and economical means. All that is needed is trained personnel to provide skilled and well-read patient care – professional dermatologists.

Trained dermatologists more often than not combine several activities, ranging from seeing patients in public hospitals, clinics, in private practices acting as consultants to other specialists, teaching, and examining clinical or basic research.

Skin conditions such as psoriasis, dermatitis, eczema, infectious diseases, wounds, rosaceous and acne can all be easily treated with various compounded medications. Conventionally many of these conditions have been treated this way.

Examples of these traditional treatments are salicylic acid, menthol, phenol, coal tar solution, ichthammol, zinc oxide and dithranol. These still play an important role in treating these conditions. Also, there are many new medications that are not available as proprietary products that can be exceptionally helpful in treating skin conditions like tacrolimus, clobetasol propionate, hyaluronic acid and tretinoin.

The Compounding Pharmacist

Posted on 9, Nov | Posted by Renee

The compounding pharmacist formulates therapies customized for the individual patient for a very wide range of dermatological conditions. Such skin conditions can mean not only physical discomfort but also personal awkwardness to those who suffer them.
Working closely with the dermatologist, expert compounding physicians prepare both therapeutic and cosmetic medications in a wide variety of formats depending on the requirements of the individual client. These include cosmetic creams, powders, and sprays for direct application to the skin, as well as a number of different oral formats from flavoured wafers to lollipops. Such medications can be applied in cases of Acne, Athlete’s foot, Diaper rash, Molluscum contagiosum, Moles and aging spots, Roseacea, Psoriasis, Warts, Pruritis.

There are several delivery formats that cover this wide range of skin conditions. When either necessary or suitable, constituent medications can be combined to make the application of the medication uncomplicated.

All other substances that may be utilized to improve transdormal absorption of the effective medication are selected from the USP approved list. The compounding pharmacists normally prepare medications that are developed by the dermatologist for special cases as well as for the familiar medications that are known to dermatologists through their special training.

There is more than one reason to make use of compounded medicine. This article discusses these reasons in detail in the subsequent paragraphs.

  • Variation: In many cases, a variety of dosage forms is needed; be it oral, topical, liquid, sublingual, suppository.
  • Potency: There is a need for individual and/or mass compounding.
  • Allergies: Commercially available preparations are not in the potency that you might need. For example; the patient may be allergic to fillers or dyes in commercially prepared formulations.
  • Availability: The medication of choice or as prescribed by the dermatologist may no longer be available commercially. Often the main chemical ingredient for compounding the formulation needs to be ordered separately.
  • Side-Effects: The manufactured oral medication may cause nausea or other gastric side-effects. So there is often a need to compound the medication topically for maximized benefits and minimized side-effects.
  • Flavouring: The medication’s taste needs to be changed or diluted to enhance its compliance and consumption.

Vet Compounding

Posted on 4, Nov | Posted by Renee

Knowledge of the quality, strength (concentration), purity and availability of the molecule in the formulation that we intend to administer is essential to rational therapeutic drug use. Further, it is the veterinarian’s responsibility to practice medicine scientifically and ethically. If we believe these statements to be true and valid, then we can understand that various levels of scientific or empirical evidence regarding the nature of a particular drug formulation provides us with various levels of guarantee that patients will favourably respond to the administration of a drug.

The main assurance for safe and effective use of a drug comes when the available drug formulation (dosage form, excipients, concentration, etc.) is associated with a desirable response, without any unpleasant adverse effects, as evidenced in controlled clinical trials that assessed safety and efficacy. When well-controlled clinical studies are not available, then we must use more unsubstantiated supportive information which includes data collected from other species, pharmacokinetic data, case series and/or anecdotal reports. As the specificity and impartial nature of the supporting data weakens, our confidence in the drug’s result should also weaken. We must keep in mind the value of the available evidence for safety and effectiveness, when applying any remedy. (more…)

Veterinary Trust

Posted on 2, Nov | Posted by Renee

Has it ever happened to you how competitive pricing, counterfeit drugs, untrustworthy sources for drugs and the honesty that our profession must maintain present an everyday dilemma? How can veterinarians avoid being affected by gossips of adulterated and contaminated food and drugs and still maintain the public’s trust?

Dawn Merton Boothe, DVM, Ph.D., Dipl. ACVIM and ACVCP, director of pharmacology at Auburn University, asked veterinarians to contest the adulteration of products in her letter to the editor in the Dec. 1 Journal of the American Veterinary Medical Assn.
Compounded drugs aren’t approved by the Food and Drug Administration. When approved drugs are not available, or are not suitable because of the way they are packaged by the manufacturer for a doctor’s intended use in a particular patient, compounding of that drug is allowed. Though the compounding industry is growing fast, it is not well regulated yet. (more…)
