Due to these advantages, the growth of sprinkle products picked up since the 1990s, and

However, the large size of solid formulations is challenging Oral delivery is regarded as the most desirable route for patients with dysphagia –often the elderly and children – of administration, given its non-invasiveness and high to swallow, which in turn promoted the development of patient acceptability [1] . Among the various types of novel oral formulations, including sprinkle formulations oral formulations, solid dosage forms like capsules and [1,4-6] .

Sprinkle formulations are drug-containing pellets accessdata.fda.gov/scripts/cder/daf/ ; last accessed October or granules that can be mixed with soft food before 2018). The product list was compiled based on the labeling administration ( Fig. 1 ). These formulations provide almost information of each product ( Tables 1–7 ). Unless otherwise the same dosing flexibility and ease of ingestion as liquid noted, the other information including generic name, drug formulations when sprinkled on liquid or semi-solid vehicles, substance, pharmaceutical ingredients, storage condition, and such as applesauce, pudding or yogurt [2,6] . The food taken administration method was also adapted from each product together with the drug can also mask the unpleasant taste labeling. and smell of the drug substance, which potentially improves patient compliance [7] . Moreover, sprinkle formulations are 2.2. Tablets available in tablet or capsule formulations for the convenience of handling and can be readily crushed or opened before being The labeling of tablet formulations usually carries a warning sprinkled on food, respectively [8] . Due to their solid state, that the product must not be crushed [10] . However, there sprinkle formulations guarantee the higher stability of loaded are more than nine crushable tablet products commercially drugs than liquid formulations during storage [9] . available. The administration of this sprinkle tablet is Since the first product was approved by the US Food performed by carefully crushing the tablet and immediately and Drug Administration (FDA) in the early 1940s, sixty-five original sprinkle formulations have been marketed in the US ( Fig. 2 ). The commercially available sprinkle formulations can be classified into seven formulation types, consisting of tablets, powder, granules, immediate-release (IR) capsules, extended-release (ER) capsules, delayed-release (DR) capsules, and multiparticulate drug delivery system (MDDS). Tables 1–7 show the formulation types arranged by the date of approval in the US. This review aims to provide the information of each sprinkle product regarding its drug substance, pharmaceutical ingredients, storage condition, and administration method. In addition, FDA guidance articles related to sprinkle formulations were introduced for the future development of this formulation.

(2) Modified-release products, of which drug release can be changed by splitting, should not be pre-scored. (3) The split tablet should be stable for 90 d under ambient condition. (4) The split tablet portions should meet the same criteria of finished-product testing as for a whole-tablet product of equivalent strength. However, this information is not directly applicable to sprinkle dosage forms. In May 2012, the US FDA released a brief guideline on the products labeled for sprinkle, where the following three recommendations are listed [24] . The first is the maximum bead size of sprinkle drug products. The agency recommends a target bead size up to 2.5 mm with less than 10% variation and a maximum size of 2.8 mm to avoid inadvertent chewing. The unintentional chewing of beads may compromise the safety and efficacy of the loaded drug. For example, a burst or an early release of the drug may occur for the ER or DR beads, respectively, and the unpleasant taste of released drug may lead to poor compliance with the oral  Fig. 3 –Schematic illustration of SODAS R technology. The administration. Indeed, the labeling of most sprinkle beads spherical bead has a multilayered structure, of which the states that the contents should not be crushed, chewed, drug-containing core is coated with the layers of split, or dissolved. The second topic of the guidance is the release-controlling polymers. administration of the sprinkle products via the enteral feeding tube. According to these recommendations, the sprinkle drug products need to be delivered through an enteral feeding  ADHD. Ritalin LA R and Focalin TM XR are designed based tube without loss of dose, crushing of beads, and tube  on SODAS R technology, with which uniform spherical occlusions. Also, the manufacturer should display special beads of approximately 1 to 2 mm in diameter can be instructions on the product labeling regarding the information  produced. The schematic illustration of SODAS R is shown on this alternative delivery method. The third part of guidance in Fig. 3 . The spherical bead has a multilayered structure contains the recommendations related to the bioequivalence of a drug/excipients core and release-controlling polymer and bioavailability studies. For the labeling to state that coatings [20,21] . The polymers in the coating layers can the drug product can be sprinkled, the information on the be water soluble, insoluble, or even pH-responsive. Their bioavailability or bioequivalence of the sprinkled formulation physicochemical properties directly affect the release pattern versus its intact form (for new drug applications, NDAs) or of the final product [2] . Additionally, by compounding beads reference listed drug (for abbreviated new drug applications, with different coatings, a customized drug-release profile ANDAs) should be included, respectively. Regarding the IR  can be achieved, which makes SODAS R a versatile oral drug sprinkle products, the bioequivalence study is not necessary delivery system [2] . because their pharmacokinetic properties are expected to be  Verelan R PM (verapamil hydrochloride; Schwarz Pharma) similar compared with the IR product of reference listed drug. is used for the management of essential hypertension. Recently in July 2018, the US FDA released a draft  Verelan R PM administered at bedtime shows a 4 to 5 h of delay guidance on the use of liquids and/or soft foods as vehicles  in drug release. This product contains DR beads of CODAS R , for drug administration [25] . This article encompasses not of which release-controlling polymer layer consists of both only general considerations for soft food vehicles but also water-soluble and insoluble polymers. When contacted with methodologies for assessing the impact of the vehicles on water in the gastrointestinal tract, the water-soluble polymer the drug product quality. The general considerations and in the coating gradually dissolves forming drug-releasing recommendations part focuses on the compatibility and pores.

Moreover, the product labeling needs to contain more than one example of soft food, because the limited 3. FDA guidance of sprinkle formulations types of food are inconvenient for patients with allergy or intolerance. A practical guidance that contains assessment criteria for When evaluating the compatibility and suitability, not only manufacturing and quality control of sprinkle formulations the properties of drug substance or drug product but also has been needed. The FDA guidance on tablet scoring is those of foods, such as acidity and drug-binding/chelating related to this issue to a certain degree [23] .
