Phenazopyridine

By D. Tempeck. Greenville College.

The International Finance Corporation and the Overseas Private Invest- ment Corporation can work to encourage better private sector pharmaceu- tical manufacturing in developing countries discount phenazopyridine amex. With the initial investments made purchase phenazopyridine 200 mg otc, governments can take on the more manageable role of encouraging partnerships with foreign manufacturers buy phenazopyridine once a day. Recommendation 4-1: The International Finance Corporation and the Overseas Private Investment Corporation should create separate invest- ment vehicles for pharmaceutical manufacturers who want to upgrade to international standards. Governments can complement this effort by encouraging partnerships between local and foreign manufacturers. In practice, it is diffcult to distinguish the quality failures that are to blame on a manufacturer’s inability to meet international best practices from those that come from a decision to cut corners and produce inferior products for poorly regulated markets. When a producer capable of meet- ing international standards fails to do so consistently and only in product lines sold to the poor, one may conclude that noncompliance is part of a more insidious system. Rich countries enforce high quality standards for medicines, and manu- facturers recognize the need to use quality ingredients and good manufac- Copyright © National Academy of Sciences. United Nations agencies and larger international aid organizations will also refuse to do business with com- panies that cannot meet stringent regulatory authority quality standards. Manufacturers are aware, however, that low- and middle-income countries are less likely to enforce these standards. When a manufacturer produces medicines of inferior quality for less exacting markets it is known as tiered or parallel production. When regulatory checks on production are inconsistent, good procure- ment practices can ensure that quality medicines get the largest market share. The frms that offer the cheapest prices do so by buying impure ingredients and cutting corners in formulation. Good procurement dictates that the cheapest tenders are not accepted if they are of dubious quality, but it is diffcult not to be swayed by price. Proper precaution in medicines procurement can prevent poor-quality products from infltrating the mar- ket. Good procurement puts a strong emphasis on controlling corruption and promoting transparency. Recommendation 4-2: Procurement agencies should develop a plan, within the next 3 to 5 years, to comply with the World Health Orga- nization’s Model Quality Assurance System for procurement agencies and work to remove any barriers to compliance. The regulator can only confrm that the producer is unknown and turn the case over to law enforcement. The police and detectives who inherit these cases have a diffcult job gathering suffcient evidence for a prosecution there is usually little if anything to tie the falsifed drug in the market to the culprit. Criminals run lucrative businesses making and traffcking fake medi- cines, and these crimes are mostly opportunistic, emerging where regulatory systems are weakest. When criminals target the products of multinational, innovator pharmaceutical companies, the companies’ security staff build evidence for a conviction. Police are also investigating more pharmaceuti- cal crimes, but most police action is limited to brief raids. It is diffcult for police to keep up momentum for sustained action on pharmaceutical crime, especially given the immediate pressure to investigate murders and other violent crimes. The high demand and erratic supply of drugs, weak regulatory systems, and un- even awareness contribute to the trade in both falsifed and substandard drugs. Medicines are what economists describe as an inelastic good; changes in the unit price of the medicine have proportionately little effect on the demand. Price inelasticity, combined with a high relative price, make medi- cines a major expense for patients around the world. Drug shortages drive up the price of medicines and push consumers to unregulated markets. Reducing the costs and increasing the availability of medicines would help prevent drug scarcity. For generic manufacturers, companies that generally run on low margins, the costs of proving bio- equivalence and preparing a manufacturer’s dossier for regulatory review can be prohibitive to market entry. Different regulatory authorities have different, often widely divergent, requirements. To complicate the problem, many small regulatory authorities lack the technical depth to evaluate the bioequivalence data that generics manufacturers submit. The high cost of market authorization impedes the development of a strong generics industry in poor countries. A more robust generic drug mar- ket could help prevent the drug shortages and price spikes that encourage the sale of poor-quality products. Regulatory authorities can work to better harmonize their procedures, thereby improving their own effciency and reducing barriers to market entry for good-quality generics manufacturers. The use of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use Com- mon Technical Document format for registration would ease the regulatory burden on generics companies. Regulators also reap a spillover beneft of more convergent regulatory systems without negotiating cumbersome mu- tual recognition agreements.

In women who have predisposing factors such as a personal or family history of deep venous thrombosis or pulmonary embolism cheap phenazopyridine 200mg without prescription, severe varicose veins, obesity, surgery, trauma or prolonged bed- rest, the overall risk may outweigh the beneft. Ethinylestradiol* Pregnancy Category-X Schedule H Indicatons Hormone replacement for menopausal symp- toms; osteoporosis prophylaxis; palliaton in breast cancer in men and postmenopausal women; contracepton in combinaton with a progestogen; dysfunctonal uterine bleeding, prostatc carcinoma.

Anovulatory infertlity: Adult- 20 mg daily on second- ffh day of the menstrual cycle. Contraindicatons Hypersensitvity, deep vein thrombosis, pulmonary embolism, pregnancy (Appendix 7c) (exclude before treatment and advise non-hormonal contracepton if appropriate), lactaton (Appendix 7b). Precautons If patent experiences swelling around ankles or legs, decrease salt intake, cystc ovarian swellings in premenopausal woman. Hot fushes, nausea, vomitng; vaginal discharge and bleeding, menstrual irregularites, increased risk of venous thromboembolism; distaste of food; depression; hair thinning; hypercalcaemia; peripheral oedema; decreased platelet count; increased pain and hypercalcaemia with bony maetastasis; tumor fare; liver enzyme changes (rarely, cholestasis); hepatts; hepatc necrosis; hypertriglyceridaemia (sometmes with pancreatts). The adrenal cortex normally secretes hydrocortsone which has glucocortcoid actvity and weak mineralocortcoid actvity. Fludrocort- sone has glucocortcoid propertes but it has potent mineralocor- tcoid propertes and is used for its mineralocortcoid efects. In pharmacological (high) doses, glucocortcoids decrease infammaton and suppress the immune response. If suppressive doses are given for prolonged periods, the adrenal cortex may undergo atrophy and this leads to a defciency on sudden withdrawal or dosage reducton or situatons such as stress or trauma where cort- costeroid requirements are increased. Afer high dosage or prolonged therapy, withdrawal should be gradual, the rate depending on various factors including patent response, cortcosteroid dose, duraton of treatment and disease state. The suppressive acton of a cortcosteroid on cortsol secre- ton is least when given in the morning. Cortcosteroids should normally be given in a single morning dose to atempt to mini- mize pituitary-adrenal suppression. Because the therapeutc efects of cortcosteroids are of longer duraton than the metabolic efects, intermitent therapy may allow the body’s normal metabolic rhythm and the therapeutc efects to be maintained. Alternate day dosing is, however, suitable only in certain disease states and with cortcosteroids with small mineralocortcoid efects and a relatvely short duraton of acton. Hydrocortsone is used in adrenal replacement therapy and on a short-term basis by intravenous injecton for the emer- gency management of some conditons. Its mineralocortcoid actvity is too high for it to be used on a long-term basis for disease suppression. The mineralocortcoid actvity of fudro- cortsone is also high and its ant-infammatory actvity is of no clinical relevance. It is the actve metabolite of prednisone, conversion of which is vari- able and prednisone should not be used interchangeably with prednisolone. Dexamethasone has very high glucocortcoid actvity in conjuncton with insignifcant mineralocortcoid actvity making it partcularly suitable for high-dose therapy in conditons where water retenton would be a disadvantage such as cerebral oedema. It also has a long duraton of acton and this, together with its lack of mineralocortcoid actvity makes it partcularly suitable for conditons requiring suppres- sion of cortcotrophin secreton such as congenital adrenal hyperplasia. Adverse Efects of Cortcosteroids: Overdosage or prolonged use may exaggerate some of the normal physiological actons of cortcosteroids leading to mineralocortcoid and glucocortcoid adverse efects. Mineralocortcoid adverse efects include hypertension, sodium and water retenton and potassium loss. These efects are most marked with fudrocortsone but are signifcant with hydrocortsone, occur slightly with prednisolone and are negligible with dexamethasone. Glucocortcoid adverse efects include diabetes mellitus and osteoporosis which is of partcular importance in the elderly since it may result in osteoporotc fractures of the hip or vertebrae. Mental distur- bances can occur, including serious paranoid state or depres- sion with risk of suicide, partcularly in patents with a history of mental disorders; euphoria is also common. High doses may cause Cushing syndrome (typical moon face, striae and acne), which is usually reversible on withdrawal of treatment, but this should always be tapered gradually to avoid symp- toms of acute adrenal insufciency (see also Withdrawal). In children, cortcosteroids may result in suppression of growth and cortcosteroids administered during pregnancy can afect adrenal development in the fetus. Any adrenal suppression in the neonate following prenatal exposure usually resolves spontaneously afer birth and is rarely, clinically important. Healing of wounds may be impaired and infectons and thin- ning of the skin may occur; spread of infectons may result from modifcaton of tssue reactons. Abrupt withdrawal afer a prolonged period may lead to acute adrenal insufciency, hypotension or death (see Withdrawal of Systemic Cort- costeroids, below).

Manufacturers should ensure that qualification and validation are performed; all necessary resources are provided, including appropriately qualified and trained personnel; adequate premises and space; suitable equipment and services; appropriate materials, containers and labels; approved procedures and instructions; suitable storage and transport; adequate personnel, laboratories and equipment for in process controls; instructions and procedures are written in clear and unambiguous language, specifically applicable to the facilities provided; operators are trained to carry out procedures correctly; records are made (manually and/or by recording instruments) during manufacture to show that all the steps required by the defined procedures and instructions have in fact been taken and that the quantity and quality of the product are as expected; any significant deviations are fully recorded and investigated; records covering manufacture and distribution, which enable the complete history of a batch to be traced, are retained in a comprehensible and accessible form; the proper storage and distribution of the products minimizes any risk to their quality; a system is available to recall any batch of product from sale or supply; complaints about marketed products are examined, the causes of quality defects investigated, and appropriate measures taken in respect of the defective products to prevent recurrence. Used clothes, if reusable, should be stored in separate closed containers until properly laundered and, if necessary, disinfected or sterilized. The key elements of a qualification and validation programme of a company should be clearly defined and documented in a validation master plan. Any aspect of operation, including significant changes to the premises, facilities, equipment or processes, which may affect the quality of the product, directly or indirectly, should be qualified and validated. An on-going programme should follow their first implementation and should be based on an annual review. The commitment to maintain continued validation status should be stated in the relevant company documentation, such as the quality manual or validation master plan. A written report summarizing the results recorded and the conclusions reached should be prepared and stored. Processes and procedures should be established on the basis of the results of the validation performed. It is of critical importance that particular attention is paid to the validation of analytical test methods and automated systems. If a product defect is discovered or suspected in a batch, consideration should be given to whether other batches should be 138 checked in order to determine whether they are also affected. In particular, other batches that may contain reprocessed product from the defective batch should be investigated. Complaints records should be regularly reviewed for any indication of specific or recurring problems that require attention and might justify the recall of marketed products. The authorized person should be responsible for the execution and coordination of recalls. He/she should have sufficient staff to handle all aspects of the recalls with the appropriate degree of urgency. All licensing authorities of all states to which a given product has been distributed should be promptly informed of any intention to recall the product because it is, or is suspected of being, defective. The report should include; (a) Self-inspection observations; (b) Evaluation and conclusions; (c) Recommended corrective actions. The company management should evaluate both the self-inspection report and the corrective actions as necessary. The duties of responsible staff may be delegated to designated deputies of a satisfactory qualification level. Key personnel include the head of production, the head of quality control and the authorized person. In large organizations, it may be necessary to delegate some of the functions; however, the responsibility cannot be delegated. Their education should include the study of an appropriate combination of: (a) Chemistry (analytical or organic) or biochemistry; (b) Chemical engineering; (c) Microbiology; (d) Pharmaceutical sciences and technology; (e) Pharmacology and toxicology; (f) Physiology; (g) Other related sciences. They should also have adequate practical experience in the manufacture and quality assurance of pharmaceutical products. In order to gain such experience, a preparatory period may be required, during which they should exercise their duties under professional guidance. The scientific education and practical experience of experts should be such as to enable them to exercise independent professional judgement, based on the application of scientific principles and understanding to the practical problems encountered in the manufacture and quality control or pharmaceutical products. The heads of the production and quality control generally have some shared, or jointly exercised, responsibilities relating to quality. The head of the production generally has the following responsibilities: (a) to ensure that products are produced and stored according to the appropriate documentation in order to obtain the required quality; (b) to approve the instructions relating to production operations, including the in-process controls, and to ensure their strict implementation; (c) to ensure that the production records are evaluated and signed by a designated person; (d) to check the maintenance of the department, premises, and equipment; (e) to ensure that the appropriate process validations and calibrations of control equipment are performed and recorded and the reports made available; (f) To ensure that the required initial and continuing training of production personnel is carried out and adapted according to need. The head of the quality control generally has the following responsibilities; (a) to approve or reject starting materials, packaging materials and intermediate, bulk and finished products in relation with their specification; (b) to evaluate batch records; (c) to ensure that all necessary testing is carried out; (d) to approve sampling instructions, specifications, test methods and other quality control procedures; (e) to approve and monitor analyses carried out under contract; (f) to check the maintenance of the department, premises and equipment; (g) to ensure that the appropriate validations, including those of analytical procedures, and calibrations of control equipment are carried out; (h) to ensure that the required initial and continuing training of quality control personnel is carried out and adapted according to need. The authorized person from Quality Assurance is responsible for compliance with technical or regulatory requirements related to the quality of finished products and the approval of the release of the finished product for sale. The authorized person will also be involved in other activities, including the following; (a) implementation (and, when needed, establishment) of the 141 quality system; (b) participation in the development of the company’s quality manual; (c) supervision of the regular internal audits or self –inspections; (d) oversight of the quality control department; (e) participation in external audit (vendor audit) (f) Participation in validation programmes.
