BACKGROUND: Antihypertensive agents are selected primarily for their ability to prevent morbidity and mortality related to hypertension. METHODS AND RESULTS: Prescribing trends and the cost of antihypertensive drugs were studied in 300 patients attending an internal medicine clinic. Beta-blockers were the most frequently used group of drugs (46.7%), followed by calcium-channel antagonists (34.3%) and angiotensin-converting enzyme inhibitors (30%). Diuretics were used in only 13.2% of the prescriptions. Atenolol (36%), amlodipine (29.3%) and enalapril (19%) were the most frequently used individual drugs. Propranolol, furosemide, amlodipine and atenolol were the least expensive drugs used, with annual drug acquisition costs of Rs 80, 102, 182 and 318, respectively. Benazepril (Rs 1778), diltiazem SR (Rs 1777), lisinopril (Rs 1660), prazosin (Rs 1416) and losartan (Rs 1365) were the most expensive drugs in terms of annual drug acquisition costs. CONCLUSIONS: The results of our study emphasize the need to encourage frequent use of diuretics. Since the costs of different antihypertensives vary considerably, newer and relatively expensive antihypertensives should be prescribed only when clearly indicated.

BACKGROUND: Monitoring spontaneous adverse drug reactions is one of the epidemiological methods for assessing the safety of drugs in a hospital setting. METHODS: Data on adverse drug reactions (ADRs) were collected over a 3-year period among inpatients in a north Indian referral hospital using the spontaneous ADR monitoring system. RESULTS: A total of 317 ADRs were reported. Cutaneous reactions (38.8%) and gastrointestinal disturbances (28.4%) made up a large proportion of reported ADRs. Antimicrobial agents, including those used for antituberculosis therapy, were responsible for 47.3% of the events. Radiocontrast dyes, and antineoplastic and psychoactive agents were the other important drugs causing ADRs. No age- or sex-related differences were found in the overall rate of ADRs, though toxic epidermal necrolysis was more frequent in the elderly. CONCLUSION: The pattern of ADRs and drugs involved were largely similar to those reported in the western literature.

Use of fluoroquinolones has increased considerably in the last 5-6 years in our hospitals. With a view to ascertain their safety and the type of adverse drug reactions (ADRs) in our population, spontaneous reports were collected and analysed to ciprofloxacin (the most prescribed fluoroquinolone in our hospital) over a period of three and a half years. The pattern of reactions were rash in 18, severe reactions like Steven Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in 4, gastritis and diarrhoea in 3, shivering and rigors in 2, hemorrhagic purpuric spots in 2 and oedema of eye and lids with topical application in 1 patient. Most cases recovered on stoppage of the drug and symptomatic treatment. However, one case of SJS and one of TEN proved fatal. Care needs to be exercised in their use and they do not appear to be innocuous to severe and disturbing ADRs.
