The manufacture and control of oral solutions and oral suspensions has presented some problems to the industry. While bioequivalency concerns are minimal except for the antiseptic products such as phenytoin suspension , there are other issues which have led to recalls. These include microbiological, potency and stability problems. Additionally, because the population using these oral dosage forms includes newborns, pediatrics and geriatrics who may not be able to take oral solid dosage forms and may be compromised, defective dosage forms can pose a greater risk because of the population being dosed.
Thus, this guide will review some of the significant potential problem areas and provide direction to the investigator when giving inspectional coverage. The design of the facilities are largely dependent upon the type of products manufactured and the potential for cross-contamination and microbiological contamination. For example, the facilities used for the manufacture of OTC oral products might not require the isolation that a steroid or sulfa product would require.
Review the products manufactured and the procedures used by the firm for the isolation of processes to minimize contamination. Observe the addition of drug substance and powdered excipients to manufacturing vessels to determine if operations generate dust.
Observe the systems and the efficiency of the dust removal system. The firm's HVAC Heating Ventilation and Air Conditioning system may also warrant coverage particularly where potent or highly sensitizing drugs are processed.
Some manufacturers recirculate air without adequate filtration. Equipment should be of sanitary design. This includes sanitary pumps, valves, flow meters and other equipment which can be easily sanitized. Ball valves, packing in pumps and pockets in flow meters have been identified as sources of contamination. In order to facilitate cleaning and sanitization, manufacturing and filling lines should be identified and detailed in drawings and SOPs.
In some cases, long delivery lines between manufacturing areas and filling areas have been a source of contamination. Also, SOPs, particularly with regard to time limitations between batches and for cleaning have been found deficient in many manufacturers.
Review cleaning SOPs, including drawings and validation data with regard to cleaning and sanitization. Equipment used for batching and mixing of oral solutions and suspensions is relatively basic. Generally, these products are formulated on a weight basis with the batching tank on load cells so that a final Q.
Volumetric means, such as using a dip stick or line on a tank, have been found to be inaccurate. In most cases, manufacturers will assay samples of the bulk solution or suspension prior to filling. A much greater variability has been found with batches that have been manufactured volumetrically rather than by weight. Unfortunately, the manufacturer relied solely on the bulk assay. After readjustment of the potency based on the assay, batches occasionally were found out of specification because of analytical errors.
The design of the batching tank with regard to the location of the bottom discharge valve has also presented problems. Ideally, the bottom discharge valve is flush with the bottom of the tank.
In some cases valves, including undesirable ball valves, have been found to be several inches to a foot below the bottom of the tank. In others, drug or preservative was not completely dissolved and was lying in the "dead leg" below the tank with initial samples being found to be subpotent. For the manufacture of suspensions, valves should be flush. Review and observe the batching equipment and transfer lines. With regard to transfer lines, they are generally hard piped and easily cleaned and sanitized.
In some cases manufacturers have used flexible hoses to transfer product. It is not unusual to see flexible hoses lying on the floor, thus significantly increasing the potential for contamination. Such contamination can occur by operators picking up or handling hoses, and possibly even placing them in transfer or batching tanks after they had been lying on the floor. It is also a good practice to store hoses in a way that allows them to drain rather than be coiled which may allow moisture to collect and be a potential source of microbial contamination.
Observe manufacturing areas and operator practices, particularly when flexible hose connection are employed. Another common problem occurs when a manifold or common connections are used, especially in water supply, premix or raw material supply tanks. Such common connections have been shown to be a source of contamination. The physical characteristics, particularly the particle size of the drug substance, are very important for suspensions. As with topical products in which the drug is suspended, particles are usually very fine to micronized less than 25 microns.
For syrups, elixir or solution dosage forms in which there is nothing suspended, particle size and physical characteristics of raw materials are not that important. However, they can affect the rate of dissolution of such raw materials in the manufacturing process. Raw materials of a finer particle size may dissolve faster than those of a larger particle size when the product is compounded.
Examples of a few of the oral suspensions in which a specific and well defined particle size specification for the drug substance is important include phenytoin suspension, carbamazepine suspension, trimethoprim and sulfamethoxazole suspension, and hydrocortisone suspension.
Review the physical specifications for any drug substance which is suspended in the dosage form. In addition to a determination of the final volume Q. For oral suspensions, there is the additional concern with uniformity, particularly because of the potential for segregation during manufacture and storage of the bulk suspension, during transfer to the filling line and during filling.
Review the firm's data that support storage times and transfer operations. There should be established procedures and time limits for such operations to address the potential for segregation or settling as well as other unexpected effects that may be caused by extended holding or stirring. For oral solutions and suspensions, the amount and control of temperature is important from a microbiological as well as a potency aspect.
For those products in which temperature is identified as a critical part of the operation, the firm's documentation of temperature, such as by control charts, should be reviewed.
There are some manufacturers that rely on heat during compounding to control the microbiological levels in product. For such products, the addition of purified water to final Q. In addition to drug substances, some additives, such as the parabens are difficult to dissolve and require heat. The control and assurance of their dissolution during the compounding stage should be reviewed. From a potency aspect, the storage of product at high temperatures may increase the level of degradants.
Storage limitations time and temperature should be justified by the firm and evaluated during your inspection. There are also some oral liquids which are sensitive to oxygen and have been known to undergo degradation. This is particularly true of the phenothiazine class of drugs, such as perphenazine and chlorpromazine. The manufacture of such products might require the removal of oxygen such as by nitrogen purging.
Additionally, such products might also require storage in sealed tanks, rather than those with loose lids. Manufacturing directions for these products should be reviewed. There are some oral liquids in which microbiological contamination can present significant health hazards. For example, some oral liquids, such as nystatin suspension are used in infants and immuno-compromised patients, and microbiological contamination with organisms, such as Gram-negative organisms, is objectionable.
There are other oral liquid preparations such as antacids in which Pseudomonas sp. For other oral liquids such as cough preparations, the contamination with Pseudomonas sp. Obviously, the contamination of any preparation with Gram-negative organisms is not desirable. In addition to the specific contaminant being objectionable, such contamination would be indicative of a deficient process as well as an inadequate preservative system.
The presence of a specific Pseudomonas sp. For example, the fact that a Pseudomonas putida contaminant is present could also indicate that Pseudomonas aeruginosa, a similar source organism, could also be present. Both the topical and microbiological inspection guides discuss the methods and limitations of microbiological testing.
Similar microbiological testing concepts discussed apply to the testing of oral liquids for microbiological contamination.
Review the microbiological testing of raw materials, including purified water, as well as the microbiological testing of finished products. Since FDA laboratories typically utilize more sensitive test methods than industry, consider sampling any oral liquids in which manufacturers have found microbiological counts, no matter how low. Submit samples for testing for objectionable microorganisms. Those liquid products in which the drug is suspended and not in solution present manufacturer and control problems.
Those liquid products in which the drug is suspended and not in solution present manufacture and control problems. Depending upon the viscosity, many suspensions require continuous or periodic agitation during the filling process. If delivery lines are used between the bulk storage tank and the filling equipment, some segregation may occur, particularly if the product is not viscous. Review the firm's procedures for filling and diagrams for line set-up prior to the filling equipment.
Good manufacturing practice would warrant testing bottles from the beginning, middle and end to assure that segregation has not occurred. Such samples should not be composited. In-process testing for suspensions might also include an assay of a sample from the bulk tank. More important, however, may be testing for viscosity. Important specifications for the manufacture of all solutions include assay and microbial limits.
Additional important specifications for suspensions include particle size of the suspended drug, viscosity, pH, and in some cases dissolution. Viscosity can be important from a processing aspect to minimize segregation. Additionally, viscosity has also been shown to be associated with bioequivalency.
With regard to dissolution, there are at least three products which have dissolution specifications. These products include phenytoin suspension, carbamazepine suspension, and sulfamethoxazole and trimethoprim suspension. Particle size is also important and at this point it would seem that any suspension should have some type of particle size specification.
As with other dosage forms, the underlying data to support specifications should be reviewed. As with other products, the amount of data needed to support the manufacturing process will vary from product to product. Development data should have identified critical phases of the operation, including the predetermined specifications, that should be monitored during process validation.
For example, for solutions the key aspects that should be addressed during validation include assurance that the drug substance and preservatives are dissolved.

Q: What is compounding? A: Simply put, compounding is any manipulation of a drug beyond that described on the drug label. Manipulation might include mixing, diluting, concentrating, flavoring, or changing a drug's dosage form. Veterinary drugs should only be compounded based on a licensed veterinarian's prescription, and to meet the medical needs of a specific patient.
Examples of compounding include:. Q: When is compounding necessary? A: Compounding is usually necessary when an animal is suffering from a medical condition and there is no FDA-approved human or veterinary product available and medically appropriate to treat the patient. The decision to use a compounded preparation must be medically necessary and made within the confines of a veterinarian-client-patient-relationship.
For example, a cat needs a medication that is only available in a pill form. If the cat's owner is unable to administer the pill at home, the veterinarian might have the drug compounded into a flavored liquid that the cat will take. Realize that although compounds might be necessary in some medical situations in pets, there are benefits and risks to their use. Because compounded preparations are not approved by the FDA, there is no assurance of how well they can be expected to work e.
That's why it's best to use an approved drug, but that is not always possible and compounded medications play an important role in animal health. Q: How do compounded medications differ from the manufactured, FDA-approved ones I can get from a pharmacy or supplier? A: According to the U. In other words, compounded medications should only be prepared using FDA-approved drugs that have been crushed, had a flavor added or otherwise changed from the original form.
If they are made from ingredients that are not already approved by FDA for humans or animals, then FDA considers these preparations to be "new animal drugs," which are required to have FDA approval in order to be legally sold.
For example, let's say your animal has a unique condition that needs to be treated with eardrops, but the FDA-approved drug your pet needs is only available as a tablet. Your veterinarian can ask a compounding pharmacy to create an eardrop version of that tablet so your animal can get the treatment it needs.
In some situations veterinarians may find it necessary to compound from a source that has not been approved by the FDA to relieve the animal's suffering.
In these cases, veterinarians and pharmacists must carefully assess whether the use is consistent with state and federal law and FDA policy. The federal government is currently assessing how compounding rules should be clarified further. We will update these FAQs as new information becomes available.
Q: Are compounded drugs the same as generic drugs? How can I tell the difference? A: No, they are not the same. In general, buying a non-proprietary drug with the same ingredient and same strength as the brand name is equivalent to but often cheaper than buying the brand name version.
We are aware, however, that there are individuals who seem to respond better to either the brand name or generic version, so there can be some variation. The non-proprietary, or generic, drugs that you obtain from your veterinarian or a pharmacy are approved by the FDA.
They have been shown to be safe and effective, their label has been approved by the FDA, and their manufacturing facilities follow certain FDA specifications. The manufacturer is also required to continually ensure the shelf stability of the product as well as prove that it will be absorbed into the patient's bloodstream bioavailability. When a drug is compounded, the new form of that drug may not perform in the same manner that the FDA approved drug does.
Yes, it still incorporates the same drug ingredient, but it has been changed and you can't expect it to be identical in every way to the original drug. Therefore, the government considers compounded preparations to be drugs that they have not reviewed or approved. Q: What drugs are most commonly compounded for use in animals?
A: Common examples of appropriate compounding in veterinary practice are mixing two injectable drugs, preparing an oral paste or suspension from crushed tablets or adding flavoring to a drug. One of the most common examples of compounding for animals is modifying an FDA-approved tablet or capsule into an oral suspension; for example, crushing a tablet and adding a tuna fish flavor to make it a palatable liquid.
While often compounded and medically necessary for successful treatment of certain conditions, these four preparations are actually not examples of legal compounding as defined by the FDA.
Federal regulations require that compounded preparations be created using an FDA-approved drug as the starting ingredient. Since there is no FDA-approved product to start with in preparing these compounded medications, an active pharmaceutical ingredient i.
In addition to these four examples, some other medically necessary drugs, such as poison antidotes, are only available as compounded preparations made from active pharmaceutical ingredients API. Q: How is compounding regulated? The FDA says it generally defers day-to-day regulation of veterinary compounding by veterinarians and pharmacists to state authorities.
The United States Pharmacopeial Convention USP is a private, non-profit standard setting organization that establishes quality standards for both manufactured drugs and compounded drugs in the United States. USP has standards to ensure proper quality, purity, identity and strength when preparing compounds. It is important to note that USP standards for compounds do not require proof of safety or efficacy. Only FDA approved drugs carry assurance of safety and efficacy if used as labeled.
Q: What is known about the safety and efficacy of compounded medications? A: There is no assurance, like there is with an FDA-approved drug, that a compounded medication will be safe or effective for an animal's medical condition.
Because compounded preparations have not been evaluated and approved by the FDA, there can be some risk associated with their use. The safest and most effective choice is to use an FDA-approved product whenever possible and to only use compounded medications when your veterinarian has determined it is necessary for your animal's health.
Your veterinarian can also discuss signs and symptoms in your pet that will alert you to any unintended effects that are caused by a compounded drug. If the compounded medication is for a dog, be sure to verify with the pharmacist at the time of pick up that xylitol is not in the compounded product.
Xylitol is a natural sweetener that is used as an inactive ingredient in some compounding media available to pharmacists. However, xylitol is toxic to dogs and should not be present in products compounded for them. Q: When is compounding legal?
What criteria must be met? A: Compounding is considered legal when federal and state rules are followed. Requirements include an established Veterinarian-Client-Patient Relationship VCPR ; the individual patient has a medical condition for which a prescribed medication is needed; and the veterinarian determines that a compound is needed for the animal.
An example of compounding that would be considered legal is when a veterinarian mixes amikacin, which is FDA approved, with glycerin to make a drug mixture appropriate for treating certain resistant bacterial ear infections. Q: When is compounding a problem? A: Examples of situations where FDA has indicated it might take action to enforce the law include:. The International Academy of Compounding Pharmacists, which is a non-profit association representing compounding pharmacists and technicians, has created a Code of Ethics for its members to follow, which addresses misinformation and misperceptions about compounded drugs.
It's also important to realize that FDA-approved drugs should be used preferentially over compounded preparations in pets unless the approved drug is not available or the approved drug cannot or should not be used for some medical or safety reason. For example, in April , the FDA issued reminders to veterinarians and pharmacists regarding the compounding of pergolide, a drug that controls problems associated with equine Cushing's disease.
The letters were issued to help prevent illegal compounding and use of pergolide products that are identical to the FDA-approved, commercially-available product. FDA currently issued similar letters for 7 veterinary drugs including: pergolide Prascend , trilostane Vetoryl , phenylbutazone Butazolidin , deslorelin Sucromate , domperidone Equidone , estriol Incurin , and phenylpropanolamine Proin.
As an additional example, there is an FDA-approved product in paste form for treating stomach ulcers in horses. Any compounding pharmacy that manufactures what they call "generic Gastrogard" in a paste form is making an illegal product because they are purposefully duplicating an already-approved product.
In one study compounded omeprazole was found to be ineffective when compared with the FDA-approved version for a write-up about the study, view the article on TheHorse. While it might appear to be less expensive to buy a compounded copy of an approved drug, in the long run it presents a risk to your pet's health and can cost more correcting problems caused by an illegal copy of an approved drug.
Q: Can I use a compounded form of an approved medication because it's cheaper? A: If you use a compounded medication only because it's cheaper, you could be putting your animal's health at risk by preferentially using a drug that hasn't been shown to be safe and effective.
The FDA did a study in which showed that there are wide variations in efficacy of compounded medications. There are times when compounding may be necessary, but it isn't necessary when there's an FDA-approved drug that can adequately treat your animal's condition.
As previously mentioned, you really do not save money by buying a manufactured mimic, because if the compound fails to do what the approved drug does, you might end up spending more money in the long run to treat your animal correctly.
A: Yes, and those rules are much more strict because of the need to prevent potentially harmful residues in the meat, milk or eggs that come from the treated animals. FDA-approved products have a determined withdrawal time, which is the time from when the animal was last treated with the drug to when the animal can be slaughtered for food or the animal's milk can go to market. The withdrawal time of a compounded product is unknown because it hasn't been studied.
Where do I get that medication? A: Sometimes your veterinarian's office can compound it for you if legal in your state or they will provide a prescription and refer you to a compounding pharmacy. Check whether the compounding pharmacy you're considering is licensed within the state. Most states have an online resource where you can identify which pharmacies are licensed to do business within the state. Some might also find it helpful to see what compounding pharmacies in their state are accredited by the Pharmacy Compounding Accreditation Board.
A: No, you shouldn't, unless your veterinarian has specifically directed you to do so. Prescriptions for compounded medications are specifically written for individual animals; using one pet's compounded medication for another pet could harm your pet. Only a veterinarian can prescribe for a medication to be compounded for an animal, so giving the compounded medication to another animal is essentially practicing veterinary medicine without a license.
Therefore, the use of compounded medications is only recommended when an FDA-approved medication is not available in the appropriate formulation. When using compounded preparations, the best way to ensure your pet's safety is to discuss with your veterinarian signs and symptoms of an adverse reaction.
Also, if the appearance of the compounded medication changes color change, odor change, consistency change while you are using it, you should stop using it and call your veterinarian immediately.
Q: What are the risks associated with the use of compounded medications? A: Compounded medications have not been tested for safety and efficacy like FDA-approved drugs.
During research and development of a medication, drug manufacturers conduct FDA-required tests to demonstrate to the satisfaction of the FDA that their product is effective and safe. FDA evaluates the data before approving the drug and allowing it to be put on the market.
This is not the case with compounded medications since they have not undergone FDA's rigorous approval process. Q: Can I get a compounded medication without a prescription? A: No. Only a veterinarian can prescribe a compounded medication for an animal. Any unlawful practices, such as providing compounded medications without a valid prescription, should be reported to the state board of pharmacy.
