Part XV. Texas State Board of Pharmacy

Chapter 309. Generic Substitution

22 TAC §309.10

The Texas State Board of Pharmacy proposes new §309.10, regarding refills of prescription drug orders. The proposed rule, if adopted, will set forth the statutory requirements of section 40(m) of the Texas Pharmacy Act and will also establish a list of narrow therapeutic index drugs subject to the provisions of section 40(m) of the Texas Pharmacy Act.

The proposed §309.10 is substantially similar to §309.3(d), which also addresses refills of prescription drug orders. The Texas State Board of Pharmacy proposed amendments to §309.3 and published notice of the proposed rule in the July 3, 1998, issue of the Texas Register (23 TexReg 6829). Subsequent to the Board business meeting in August 1998, at which the Texas State Board of Pharmacy voted to adopt the proposed amendments to §309.3, a lawsuit regarding the amendments to §309.3 was filed against the Texas State Board of Pharmacy. On December 16, 1998, following arguments by legal counsel for the parties, the trial court held that the Texas State Board of Pharmacy failed to adopt the amendments to §309.3 rule in compliance with the Administrative Procedure Act and that the rule was null and void and of no force or effect. On January 13, 1999, the trial court entered the Final Judgment. At the Board business meeting on February 2, 1999, the Texas State Board of Pharmacy voted to pursue an appeal of the trial court judgment regarding the amendments to §309.3. The Texas State Board of Pharmacy also voted to propose a rule as mandated by section 40(m) of the Texas Pharmacy Act.

Accordingly, the current provision of 22 TAC §309.3(d) has been held invalid by a trial court and is the subject of a pending appeal to an appellate court by the Texas State Board of Pharmacy. The Texas State Board of Pharmacy, however, proposes new §309.10, which fulfills the requirements of section 40(m) of the Texas Pharmacy Act with respect to refills of prescription drug orders involving narrow therapeutic index drugs.

The proposed new rule incorporates the recommendations of a Task Force composed of representatives from the Texas State Board of Pharmacy, Texas State Board of Medical Examiners, pharmacy and medical associations, and generic and brand-name manufacturers. The proposed new rule outlines the conditions under which the substitution of a narrow therapeutic index drug may occur on the refill of a prescription. The proposed new rule, as specified in the legislation, requires a pharmacist to notify the patient and the prescribing physician if the pharmacist refills a prescription for a narrow therapeutic index drug with a generically equivalent product different from the product used on the previous refill. The proposed new rule also establishes a list of narrow therapeutic index drugs, which are subject to the provisions of section 40(m) of the Texas Pharmacy Act. Narrow therapeutic index drugs are drugs in which small variances in the blood levels of the drug can change the effectiveness or toxicity of the drug. The list in the proposed new rule contains those drugs that health-care practitioners generally monitor closely through lab tests to ensure that the drug remains at the appropriate blood level for the individual patient. The Texas State Board of Medical Examiners has reviewed the list recommended by the task force and agrees that the list of drugs in the proposed rule is appropriate for the purpose of section 40(m) of the Texas Pharmacy Act.

Gay Dodson, R.Ph., Executive Director/Secretary, has determined that, for the first five-year period the rule is in effect, there will be possible fiscal implications for the state as a result of enforcing or administering the rule. There are no anticipated fiscal implications for local government.

The fiscal implications for the state are based on the cost of an enforcement action by the Texas State Board of Pharmacy. Fiscal implications for the agency are anticipated to be minimal because the enforcement and administration of the proposed rule can be adequately managed with existing resources. In fiscal year 1997, as stated in the agency's Annual Report, the agency resolved 1,697 complaints and, of those complaints, only four complaints alleged violations of the laws and rules regarding substitution of narrow therapeutic index drugs. The agency cannot accurately project whether the adoption of the proposed rule will increase the number of complaints received by the agency or the number of disciplinary cases that may proceed to formal hearing. However, by using FY97 agency data, the agency can estimate the possible costs to the state for an agency enforcement action. For example, if the agency investigated and initiated disciplinary action on the four complaints involving narrow therapeutic index drugs that were received by the agency in FY97, then the cost to the agency as a result of enforcing or administering the rule is approximately $1,745.56. This estimated amount is based on the cost of a resolved jurisdictional complaint ($436.39) times the number of complaints (4). The cost of a resolved jurisdictional complaint is based on the total funds and personnel costs expended for processing and investigating a complaint, as well as the funds and personnel costs required to adjudicate a licensee who is the subject of a complaint. The funds expended include all direct costs associated with complaint resolution. These direct costs are identified in the agency's internal operating budget and, where applicable, include percent of salaries according to estimated time, rent, supplies, travel, postage, subpoena and witness expenses, cost of court reporter for hearings, charges by the State Office of Administrative Hearings, and other operating expenses directly related to the agency's enforcement function only. Indirect costs are not included in the calculation of the cost of a resolved jurisdictional complaint. Based on this calculation and assuming that complaints remain constant, the cost to the Texas State Board of Pharmacy for the next five years would be as follows: FY2000--$1,745.56; FY2001--$1,745.56; FY2002--$1,745.56; FY2003--$1,745.56; and FY2004--$1,745.56.

In addition, there may be fiscal implications to the state Medicaid program. For each Medicaid prescription dispensed by a pharmacy, the state Medicaid program pays the pharmacy a price based on a set formula. The formula includes a cost for the drug plus a dispensing fee. A pharmacist is prohibited from charging the state Medicaid program more for a prescription that calls for a narrow therapeutic index drug despite any additional time spent by the pharmacist in dispensing the prescription. Therefore, increased costs to the state Medicaid program may occur if a pharmacist refuses to substitute a lower-priced generic prescription drug product when permitted to do so, and instead dispenses a higher-priced brand name prescription drug product. In an effort to estimate the possible cost to the state Medicaid program, the agency has assumed that all pharmacists will refuse to substitute a lower-priced generic prescription drug product when permitted to do so in all cases. By using this assumption, the agency can estimate the highest possible increase in cost to the state Medicaid program. In addition, the agency calculated its estimated cost to the state Medicaid program on only six of the nine drugs on the list of narrow therapeutic index drugs in the proposed rule. The three drugs not used in the agency's calculation are digoxin, levothyroxine, and divalproex sodium. These three drugs were not included because none of these drugs have a generic equivalent in an oral dosage form that may be substituted under Texas laws and rules. The six drugs used in the agency's calculation of costs to the state Medicaid program are: phenytoin, warfarin, theophylline, carbamazepine, lithium, and valproic acid. Given the factors described above and based on information provided by the Texas Department of Health, Vendor Drug Program, which administers the Texas Medicaid Program, the agency estimates that the proposed new rule may result in increased costs to the state Medicaid program in the estimated amount of approximately $4,567,820.74 per year. The chart, in Figure: 22 TAC Chapter 309--Preamble, shows the costs of the individual drugs and the calculation used. (Please note that this is the highest possible costs and does not take into consideration possible reductions in costs as a result of manufacturer rebates to the Vendor Drug Program nor possible reductions in costs caused by the effect of the setting of Maximum Allowable Cost (MAC) on some dosage forms to the six drugs by the Vendor Drug Program. A MAC price on a drug indicates that the Vendor Drug Program has set a maximum cost that will be paid for the drug regardless of the cost of the drug to the dispensing pharmacy.)

Figure: 22 TAC Chapter 309--Preamble.

Based on the calculations and assumptions in Figure: 22 TAC Chapter 309--Preamble, the estimated cost to the Texas Vendor Drug (Medicaid) Program for the next five years would be: FY2000--$4,567,820.74; FY2001--$4,567,820.74; FY2002--$4,567,820.74; FY2003--$4,567,820.74; and FY2004--$4,567,820.74.

Ms. Dodson also has determined that, for each year of the first five-year period the rule will be in effect, the public benefit anticipated as a result of enforcing the rule will be the establishment of a list of narrow therapeutic index drugs subject to section 40(m) of the Texas Pharmacy Act. The notice requirement in the proposed rule promotes good communication between the patient, the prescribing practitioner, and the pharmacist, particularly with regard to critical care medications that require frequent monitoring of performance.

Section 2006.002 of the Texas Government Code requires that a state agency, before adopting a rule that would have an adverse economic effect on small businesses, shall prepare a statement of the effect of the rule on small businesses, defined in section 2006.001(1). The statement must include the following: (1) an analysis of the cost of compliance with the rule for small businesses; and (2) a comparison of the cost of compliance for small businesses with the cost of compliance for the largest businesses affected by the rule, using at least one of the following standards: (A) cost for each employee; (B) cost for each hour of labor; (C) cost for each $100 of sales. The Texas Pharmacy Act prohibits the agency access to pharmacy financial data. This lack of access to financial data limits the agency's ability to identify and analyze estimated costs to licensees. The costs/fiscal implications to a small business are dependent on the number of prescriptions filled by the licensee, the costs of the prescription drug dispensed by the licensee, and the costs assigned to the amount of time that the licensee must allocate to notify the prescribing practitioner that a product has been substituted for the prescribed product. The following factors also affect the agency's ability to estimate costs to small businesses: the number of prescriptions filled by a pharmacy may vary on a daily basis, the number of prescriptions that may be subject to the proposed rule may vary on a daily basis, and the prescription volume for licensed pharmacies vary according to size, number of pharmacists and pharmacy employees, demographics, and location in the state (rural versus urban pharmacy).

Given the limitations and variables that affect the agency's ability to estimate the costs, the agency is unable to give an accurate assessment of the costs. The agency does not have information with which to make a comparison between the cost of compliance for a small business and the cost of compliance for a large business affected by the rule based on costs per each employee, per each hour of labor, or per $100 of sales. Because the proposed rule requires a pharmacist to notify a patient and a prescribing practitioner of a substitution, the cost to small and large businesses will be the cost of the pharmacist's time that is necessary to make this notification. It is estimated that the notification will require no more than two minutes of the pharmacist's time per prescription. If the agency uses $26.51 as the average hourly salary for a pharmacist (Drug Topics, April 7, 1997), the costs to businesses from compliance with the rule will be approximately 88 cents per prescription. The agency cannot accurately estimate the number of prescriptions that this proposed rule will affect nor the costs to businesses because data is not available on the number of prescriptions written for the drugs on the list on which a prescribing practitioner has allowed substitution and on which a pharmacist has substituted.

There are possible economic costs to pharmacists, who are the individuals required to comply with the proposed rule. Pharmacists who are also owners of pharmacies may be affected by the various factors outlined above that effect the costs to large and small businesses. Because the agency cannot estimate the number of prescriptions that the proposed rule will affect, the agency is unable to give an accurate assessment of the fiscal implications to pharmacists.

A public hearing to receive oral comments on the rule will be held at 9:00 a.m. on Tuesday, May 4, 1999, in the Health Professions Council Board Room, William P. Hobby State Office Building, Tower 2, Room 2-225, 333 Guadalupe, Austin, Texas. Written comments on the proposal may be submitted to Gay Dodson, R.Ph., Executive Director/Secretary, Texas State Board of Pharmacy, 333 Guadalupe Street, Suite 3-600, Box 21, Austin, Texas, 78701-3942. Written comments will be accepted through Friday, June 2, 1999.

The new section is proposed under Sections 4, 16(a), and 40(m) of the Texas Pharmacy Act (Article 4542a-1, Texas Civil Statutes). The Board interprets section 4 as authorizing the agency to adopt rules to protect the public health, safety, and welfare through the effective control and regulation of the practice of pharmacy. The Board interprets section 16(a) as authorizing the agency to adopt rules for the proper administration and enforcement of the Act. The Board interprets section 40(m) as directing the agency to consult with the Board of Medical Examiners and by rule to establish a list of narrow therapeutic index drugs.

The statutes affected by this rule: Texas Civil Statutes, Article 4542a-1.
