The various embodiments of the present invention relate to the delivery topical human identical hormone replacement therapy (HIHRT), in particular to selected compositions suitable for transdermal delivery of HIHRT, a novel smart metered dose delivery device recently elucidated that facilitates both, the variable and the continuous dosing of hormones when applied to human skin; and a novel method for self-administering HIHRT through the skin route of women, both in a variable and continuous dosing manner; which attempts to mimic the temporal variations seen in serum human identical progesterone and estradiol hormone levels of healthy premenopausal women over a typical 28 day cycle. In addition, the present protocol maintains a rational dosing therapeutic window amongst specialty providers that could be adjusted to meet unique patient needs. As result, the prescriber has a full repertoire of concentration options of progesterone and estradiol; and an array of dosing combinations between topical human identical estradiol and progesterone, resulting in optimal dose control and positive patient outcomes. A dispenser is also disclosed for flowable cream-base medicaments, specifically a unidirectional rotatable platform attached to a screw that is slipped into a barrel where it is secured in place and it joins the said components that house an elevator.
Human Identical hormones have been used since the 1930's. Throughout the advancements in science, there have been several improvements in medical delivery devices and delivery compositions that employ lipophilic gel or cream bases. Nonetheless, most HIHRT dosing protocols have remained much like those since inception where continuous dosing of HIHRT is predominant amongst medical providers.
Presently, only a handful of physicians who administer the latest medical treatments to patients attempt to add a cyclic component to their patient's dosing regimen in order to better maintain their health. Some providers prescribe a static dosing for 6 days out of the week and tell their patients to refrain from taking any HIHRT on day seven. Others prescribe a static daily progesterone dose on the later part of the cycle, (on days 12 or 14 through day 28) and several other variations exist.
U.S. Pat. No. 7,879,830 exploits the use of syringes, (needle excluded) to be filled with transdermal composition of bioidentical estradiol and progesterone. The user is directed to self-administer a single concentration of estradiol and a single concentration of progesterone and vary the amount of topical composition to be applied following a dosing schedule. Therefore, the user applies the dose by carefully looking at the small demarcations lines on a syringe in order to apply the correct dose.
Seemingly, U.S. Pat. No. 7,879,830 causes all of its users to conform to a single dosing concentration of bioidentical estradiol, (1 mg 0.1 ml) dispensed in a first (3 cc) syringe (needle excluded), and to a single dosing composition of bioidentical progesterone (25 mg/0.1 ml) dispensed in a second (3 cc) syringe that follows a dosing schedule that is supposed to replicate a “physiologic reproductive hormone cycle in its dose and schedule.”
In light of the recent advancements in science, which demand a cyclical dosing pattern in order to achieve a better outcome and quality of life, it follows that the greatest challenges prescribers face today are the following: Accurate and patient friendly delivery devices capable of offering dosing flexibility, a dosing protocol that is sound to medical providers; specifically one where the provider is able to select patient specific dosages of progesterone or estradiol in accordance to their body's needs, and lastly, a protocol that would facilitate patient self-administration and would confer the ability to provide both, static and variable dosing of human identical hormone therapy that overcome the aforementioned deficiencies of the prior art.
American compounding pharmacists are increasingly dispensing hormone replacement therapy (HRT) cream-base medicines due to raised awareness of its safety profile and benefit in relieving symptoms of hormone imbalance. The challenge to dispense accurate amounts of cream-base medicine continues since delivery device options have been very limited. Not so long ago, a prevalent option for administering cream-base HRT employed the use of ⅛, or ¼ teaspoonfuls, (looking much like an ice-cream sampling spoons) partaking in a common practice called “eye balling.” Syringes are still commonly used today in the delivery of hormone replacement therapy; whereby the pressing of the plunger pushes the cream out of the chamber through the small syringe orifice (needle excluded), and the user is able to get the correct dose by counting number differences or the number of line markings passed by the indicator.
New metered only transdermal applicators have shown some interest amongst providers and consumers. For example, pumps have been extensively employed where the user depresses a pump that delivers a “somewhat” fixed volumetric amount. (There seems to be a lot of skepticism on the actual accuracy of these devices, especially dosing differences from the first to the second pump). Furthermore, pharmacists and physicians often have to adjust their dosing by taking into account large and inadequate volumetric amounts delivered by these metered-only devices. (i.e. 0.6, 0.7, 0.9 ml per pump). Needless to say, there is extensive variability between pumps.
U.S. Pat. No. 7,213,994, as disclosed, allows for the delivery of a “predetermined” amount of cream through an opening in the cap. Basically, when the base is rotated 90° (clockwise, an audible and tactile “Click” is supposed to be heard translating to the delivery of a predetermined amount of cream. Furthermore, the patent claims a positive sensory feedback mechanism that confirms a desired amount of cream dispensed. The device is described as producing; in most cases, an audible sound upon a 90-degree clockwise rotation. However, consumers have reported a lack of audible sound or tactile feel on several cases, especially when the rotatable base is left in between clicking segments for prolonged periods of time, which makes it enormously difficult for consumers to apply a desired dose. The problem may be highly attributed to poor design, manufacturing defects, and poor quality assurance. To make matters worse, the said patent only delivers 0.476 g of cream-base medicament of a specific density per 1800 displacement of the base past the barrel, (or per 2-clicks as reported by the company using the Medisca® HRT Cream Base). Thus, falling short from the needed 0.5 gram standard dosing requirement.
Although both types of metered only transdermal applicators have gained some popularity amongst U.S. compounding pharmacies, (especially if compared to other delivery devices, like syringes, metered screw-on caps, pea-sized spoons, etc.) the greatest challenge faced by these devices, is convincing users, and especially health providers that a “Click” or a “Pump” translates to a specific dose. Therefore, prescribers still refrain from writing in their scripts a dose based on clicks or pumps. Instead, for several decades, providers and patients seem to favor dosages based on a number scale or with some form of graduated line markings. Further, poor mechanical design and 90 degree “click” limitations may be undesirable features to other consumers and providers. In this patent we have solved most the frustration medical prescribers and patients face today when it comes to selecting a useful device for delivering customary doses of transdermal hormone replacement therapies, as well as other uses unknown as of now. The present device offers consumers the delivery of calibrated volumetric amounts of cream-base medicament, a graduation area that allows consumers to visually measure a specified dose, the delivery of smaller, yet consistent volumes if desired, concurrent bi-audible, and bi-tactile features to provide dosing reassurance, and superior flexibility in the dosing of cream-base medicaments without the limitations of “pumps” or “clicks” posed by metered only devices.
Accordingly, the various embodiments of the present invention are directed to a novel dosing protocol that utilizes a novel delivery system by which an elaborate set of instructions cause a combined continuous and variable topical composition dosing scheme of human identical progesterone and estradiol when self-administered by a user. The protocol aims at simulating the temporal variations as seen in serum progesterone and estradiol hormone levels of premenopausal women with healthy cycles. Accurate and flexible volumetric dosing of said composition for self-administration is made possible through the use of the smart metered dose applicator, the HRTicker® as described herein. The novelty of this dosing protocol is that it facilitates prescribing, patient education, and it increases patient outcomes and quality of life.
In various embodiments of the present invention described herein, a combined continuous and variable HIHRT protocol is modeled from scientific observations on how temporal variations in serum progesterone and estradiol hormone levels fluctuate in healthy women over a 28 day cycle. The downstream impact of temporal variations in serum hormone concentrations is quite complex, yet highly speculated as a key element in the signaling pathways for how endocrine glands effect remote target organs, and therefore, have a largely impact in the health and wellbeing of women. Furthermore, the latest advancements in science make a strong case for the cyclic delivery of HIHRT in order to achieve optimal health. It follows that a protocol that combines both, static and cyclic dosing of human identical progesterone and estradiol over a 28 day cycle stretched over a Gregorian calendar month in an attempt to replicate the temporal variations in serum hormone concentrations as seen in nature, is likely to improve patient outcomes and quality of life. Additionally, a recently published study that paid particular interest to the differences in myocardial infarctions in patients that received static versus cyclic regimens showed positive outcomes in the group that received the cyclic dosing regimen.
This novel dosing regimen as described herein empowers prescribers with the option to select various concentrations of human identical estradiol and progesterone according to individual patient needs. Once a hormone concentration is prescribed, then the consumer has the ability to self-administer such concentration topically in a combined continuous and cyclical fashion simulating the temporal variations in serum hormone concentrations as seen in premenopausal women with healthy hormone cycles. All achieved, simply by following the dosing schedule provided with said protocol.
Perhaps the greatest strengths of the proposed protocol are two-fold. First, it equips medical providers with the ease and flexibility of providing to their patients numerous dosing options (dosing strengths, steps) of estradiol and progesterone that combine static and cyclic dosing regimens at any dosing strength selected for a particular patient. Second, the smart metered dose delivery system described herein (HRTicker® manufactured by BiosRx, Inc.) facilitates self-administration of variable volumetric dosages of human identical estradiol and progesterone in a topical composition to its user, as prescribed. This is vital, since patients can now self-administer complex dosages (static and variable volumetric dosages of composition) by following pre-printed dosing instructions throughout a 28 day cycle stretched over a Gregorian calendar month for practicality.
Several embodiments are also disclosed, in which a novel device employs a unidirectional rotational mechanism where visual, audible, and tactile elements work together synergistically for the delivery of calibrated volumetric amounts of topical cream-base medicaments of a specified density, or any other flowable material if warranted. The interaction of primary and secondary ticker tabs stemming from the bottom exterior wall of the house and corresponding major, minor, and redundant side ticks stemming from the rotatable platform, which allows for the delivery of specific volumetric amounts of cream-base medicaments, has not been elucidated until now.
Moreover, the interaction and involvement of selective ticker tabs stemming from the clicking zone of the house and corresponding major, minor, and redundant side ticks stationed on the rotatable platform, which are responsible for creating two different types of audible sounds and tactile sensations to the user depending on the angular displacement of the rotatable element against the house from a predetermined point of reference will be disclosed in detail.
The term ‘housing element’ or ‘house’, will be used to denote a barrel side ticks as an alternative name to side tabs, and composition as an alternative name to cream-base medicament as disclosed. One example embodiment of the dispensing apparatus includes a unidirectional rotatable platform that engages the head-bolt of a left threaded screw-complex that can be slipped into the inner chamber of the housing element and secured in place by cooperation of a snap-ring and locking tabs located on the bottom wall of the house. Once inside, the screw interacts with an elevator that fits tightly against the wall of said inner chamber. Upon clockwise axial movement of the rotatable platform against the house, audible and tactile sensations can be perceived by the user at every 18 degrees of rotation; however, the type of sound depends if the 18° rotation of the platform is directed to a minor digit tab (minor tick note, soft click) or to a major digit tab (major tick note, louder sound) since different ticker tabs are involved and interact with major, minor, or redundant side ticks depending on the displacement of the rotatable platform against the house from a predetermined point of reference. The elevator rises and pushes upward the flowable contents of such chamber, exiting through an output orifice located at the center of a dispenser, which is secured to the upper end of the house providing a surface to apply the cream or gel directly onto the skin. A removable cap with a plug to retard evaporation of the cream-base medicament is stationed on top of the dispenser. As the platform rotates, the user is able to count the number of equispaced digit tabs on the rotatable platform past the markings on the first end of the house for determining a desired dose. A left threaded rod interacts with an elevator equipped with a top and bottom edge seal useful in preventing a cream smudge trail or any visible cream from being left behind and causes it to rise. A bi-audible mechanism is in place for determining set volumetric amounts dispensed upon an 18° clockwise rotation of the rotatable platform against the house. A 90°, 180 °, 270°, or a 360 degree displacement of the rotatable platform against the house from a predetermined point of reference produces a peculiar audible and tactile sensation on the user, referred here as the first sound. Likewise, displacement other than a 90°, 180 °, 270°, or 360 degrees from a predetermined point of reference, produces a different yet distinct audible and tactile sensation on the user, referred here as the second sound. An 18° rotation of the base platform translates to a 0.05 numerical difference on the exterior wall of the rotatable platform, or one digit tab movement of the rotator past the house. It follows that a 90° rotation translates to a 0.25 numerical difference on the exterior wall of the rotatable platform with respect to the house. The device has been configured to deliver roughly one gram of a specified cream of a specific density (or 1.03 g of water at 25° C.) for every 360° rotation of the rotatable platform against the house. A dispenser pad is available to aid in the application of the cream-base medicament if so desired by the consumer.
The disclosed embodiments will be further explained with reference to the attached drawings, wherein like structures are referred to by like numerals throughout several views. The drawings displayed may not be to scale, with emphasis instead generally being placed upon the illustration of the principles of the presently disclosed embodiments.
In various embodiments, a transdermal, visual, bi-audible and bi-tactile to the senses cream applicator with calibrated, equispaced line demarcations, and supplemental numerical legend, each positioned at a predetermined 18 degree angle from one another translating to the delivery of roughly a 1/20th milliliter of flowable cream-base medicament of a specific density is described in detail herein. Additionally, a novel dosing protocol is described that utilizes a novel delivery system by which an elaborate set of instructions cause a combined continuous and variable topical composition dosing scheme of human identical progesterone and estradiol when self-administered by a user.
This novel applicator 5 comprises the following six vital elements: a rotatable platform 25, a house 470, a screw-complex 200 (see
All parts can be made of rigid plastic or a similar material, but the preferred material is polypropylene. Prototypes can be designed in ProJet, Stereolithogray (SLA), or Acura 25.
With the screw-complex 200 set in place interacting with the rotatable platform 25, house 470, and elevator 325, its mechanism can be fully appreciated. The primary ticker tabs 435 interact with minor side ticks 110 on the rotatable platform 25, and produce a unique and identifiable sound depending on the displacement of the rotatable platform 25 against the house 470. Upon an 18° displacement, primary ticker tabs 435 can clear the minor side ticks 110 to land into tab rest segments 111 and produce the second sound, or they can clear the major side ticks 112 to land into different tab rest segments 111 to produce the first sound. When the secondary ticker tabs 440 clear the redundant side ticks 115 upon an 18 degree rotation of the rotatable platform 25, the first sound is also emitted by the apparatus and captured by the senses of the consumer. Therefore, primary ticker tabs interact with major side ticks concurrently when secondary ticker tabs interact with redundant side ticks. Advantageously, there are only four major side ticks 112 strategically positioned to interact with the primary ticker tabs 440 and produce a louder identifiable sound only at key displacement locations; specifically at every 90°, 180°, 270°, and 360° displacement locations from a predetermined reference point; which also corresponds to the alignment of the 0.25, 0.50, 0.75, and 1.0 major digit tabs 70 of the rotatable platform 25 with the fixed major line markings 65 of the house 470.
In addition, at these four displacement locations, (90°, 180°, 270°, and 360°) there is sound summation taking place due to the concurrent interaction of primary ticker tabs 435 with major side ticks 112, as well as secondary ticker tabs 440 interacting redundant side ticks 115; ultimately yielding a more pronounced sound and tactile sensation at these predetermined sites.
There are four grip tabs 30 to ease rotation. Further, the lower end of the house 470 provides equispaced extruded line demarcations to create a predetermined point of reference during rotation of the rotatable platform 25. Fixed major markings 65 and fixed minor markings 50 span along the outer circumference of the lower end of the house 470. An elevator 325 residing inside the chamber of the house 470 is attached to the screw shaft 245 and causes it to rise upon clockwise rotation of the rotatable platform 25.
The house 470, which is basically a barrel, is introduced in
An extruded upper rim 415 with reinforcement ribs 416 just beneath it is situated just below the circular upper edge 410 which assists in locking the dispenser 500 upon pressing against it. The inner side wall 35 of the house 470 is directly in contact with the composition and it is perpendicular to the bottom inner wall 479; which, on its center has a void with four upward projecting locking tabs 425 for accepting and locking the screw-complex 200 in place with the house 470 only to allow rotation along its own axis. The chamber upper edge 484 concludes the upper end of the chamber; which has a semi-square shape in order to maximize volume, but it is connected to the circular upper wall 406 by a wall to wall connector 485, that terminates at the top with the circular upper edge 410.
The platform end 403 of the house 470 has a raised graduation ring 430, with twenty demarcation line markings, referred here as fixed major and minor line markings (65; 50); respectively. There are four fixed major line markings 65, separated at 90° from each other along the outer circumference of the of platform end 403 of the house 470 and sixteen fixed minor line markings 50, all forming the graduation ring 430. The primary ticker tabs 435 stemming from the platform end 403 of the house interact with minor side ticks 110 stemming from the outer base rim 160 of the rotatable platform 25 producing a unique but soft second sound at every 18° of rotation depending on the angular displacement from a predetermined point of reference. In addition, the primary ticker tabs 435 also interact with major side ticks 112 stemming from the outer base rim 160 of the rotatable platform 25 to produce a louder first sound upon clearance of the primary ticker tabs 435. The secondary ticker tabs 440 interact with the redundant side ticks 115 of the rotatable platform 25 to produce the louder first sound upon completion of an 18° movement by the platform to any major digit tab 70 position, (or a 90° predetermined angular displacement from a fixed point of reference) as well as a specific vibration that corresponds to the tactile component that users can sense. Furthermore, an even louder sound and greater tactile sensation is achieved by summation of ticker tabs to side tick interactions; specifically, primary and secondary ticker tabs interacting with major and redundant side ticks, simultaneously, where the landing of all ticker tabs take place upon completion of an 18° displacement into the major digit tabs 70. A screw orifice 450, accepts the screw-complex 200 and the locking tabs 425 override the snap ring 210 landing into the orbit area 240 of the screw-complex 200 where the screw-complex 200 is practically locked to the house 470.
Pre-Assembly: This involves the collaboration four components; the screw-complex 200, house 470, elevator 325 and rotatable platform 25. The screw end 201 and the screw-complex 200 get inserted to the house 470 past the house locking tabs 425. Once the locking tabs 425 override the snap ring 210, the screw-complex 200 gets trapped in the house 470 in parallel with the chamber's inner side wall and it's only able to rotate axially. Tooling facilitates assembly of the elevator 325 where counterclockwise rotation of the screw-complex 200 allows the elevator 325 to get screwed into the bottom end of the house 470. The hexagonal shape of the bolt head 220 allows it to be attached to an electrical female hexagonal-socket and yield assembly of the elevator 325 into the bottom end of the house 470 efficiently. Next, the rotatable platform 25 is slipped into the bottom end of the house 470 where the locking tabs 145 overrides the bolt head 220 to land into the bolt neck 235 where the platform locking tabs 145 secure the rotatable platform 25 into the other said components (25, 470, 200, 325) in a tight fit, practically fusing the rotatable platform 25 to the house-screw-complex-elevator components. The preassembled unit, along with the dispenser 500, and security cap 600, (assembly add-ons) can be shipped as a single unit or in large quantities.
Assembly: Compounding pharmacists or other dispensing personnel can place a desired quantity of the flowable cream-base medicament inside the chamber of the housing 470 through the dispenser opening 405. The dispenser 500 gets positioned to fit into the housing 470 through insertion guides 530 that fit into the dispenser notch 475a, 475b. Upon pressing, the annular groove 540 fastens into the peripheral rim 407 of the house 470. Once locked, the dispenser cannot be removed by the average consumer unless a skilled provider or technician, using a pointy tool can carefully pull the dispenser's bottom edge 525 and displace the dispenser 500 outwards. Once in place, the applicator gets primed (air removed) to a desired setting by rotating the rotatable platform clockwise; as allowed. We recommend technicians and dispensers to partially prime the unit to prevent spilling; especially if transporting to different altitudes as pressure changes may force the cream-base medicament out of the device. The security cap 600 can be inserted to prevent medicament contamination, spill, and retard medicament evaporation by sealing the outlet 505. The security cap 600 can also be fastened to a tight fit if one applies additional force by cooperation of the semi-annular rib 645 and safety rim 408. A thumb tab 611 is placed near the lower edge 635 and lower outer side wall 615 of the safety cap 600 to ease removal.
Minor Tick Note: This is the sound and tactile sensation caused by the interaction of primary ticker tabs 435 stemming from the bottom exterior wall 480 of the house 470 with minor side ticks 110 stemming from the outer base rim 160 of the rotatable platform 25 due to an 18° displacement of the rotatable platform 25 against the house 470 to any predetermined minor digit tab (other than digit tabs 0.25, 0.50, 0.75, and 1.0). A soft and distinct sound and tactile sensation is captured by the user upon clockwise rotation of the rotatable platform 25 against the house 470 of the apparatus at any of these predetermined angular displacements allowed.
Major tick Note: This is the sound and tactile sensation caused by interaction of primary ticker tabs 435 and major side ticks 112 plus the concurrent interaction of secondary ticker tabs 440 stemming from the bottom exterior wall 480 of the house 470 with redundant side ticks 115 stemming from the inner base rim 150 of the rotatable platform 25 due to an 18° displacement of the rotatable platform 25 with respect the house 470 to the following predetermined major digit tabs, 0.25, 0.50, 0.75, and 1.0. This summation, and thus amplification of sound and tactile sensations makes for a bi-audible and bi-tactile apparatus.
