ABSTRACT
BACKGROUND: Surgical extraction of third molars is associated with postoperative pain and swelling at the extraction site. Pain is commonly managed using non-steroidal anti-inflammatory drugs (NSAIDs). Postoperative pain is usually moderate to severe in the first 12 h postoperatively and lasts for 3-5 days. However, with NSAIDs, these symptoms usually subside within 24 h. Diclofenac sodium and etodolac are NSAIDs, more selectively cyclooxygenase-2 inhibitors, with good analgesic efficacies. METHODS: We compared the safety and analgesic efficacy of diclofenac sodium with etodolac peroral after surgical extraction of third molars in a double-blind, double-dummy, parallel-group study. The subjective pain improvement and pain relief after 2, 6, 24, 48, and 72 h using the visual analogue scale were measured as the study outcome. RESULTS: Etodolac was equivalent to diclofenac sodium in pain alleviation at all postoperative time periods. No significant differences were found between diclofenac sodium and etodolac groups (P > 0.05). Both study medications were well tolerated and safe with mild adverse effects in only a few participants. CONCLUSION: Diclofenac sodium and etodolac are comparable in terms of analgesic efficacy and safety after surgical removal of third molars.
ABSTRACT
Systemic lupus erythematosus (SLE) can be induced by various medications, such as hydralazine, procainamide, isoniazid, methyldopa, chlorpromazine, quinidine, and minocycline. A patient was admitted complaining of fever with chills and rigor. After being diagnosed with tuberculous meningitis, the patient was given antituberculosis treatment. As the patient did not improve, detailed investigations were conducted, and elevated antinuclear antibody levels were found. The consulting physician diagnosed that the patient was suffering from SLE. As isoniazid is associated with an increased risk of developing SLE, it was suspected as the culprit drug. After withdrawing isoniazid from the antituberculosis treatment regimen, the patient improved and was discharged. Based on the WHO-UMC and Naranjo's causality assessment criteria, an association between the reaction and isoniazid was deemed probable. The reaction was moderately severe (level 4b) according to the modified Hartwig and Siegel scale.
ABSTRACT
Fixed drug eruption (FDE) was caused by fixed-dose combination (FDC) of antituberculosis drugs in the form of tablet Forecox® (rifampicin [rifampin] 225 mg + isoniazid 150 mg + pyrazinamide 750 mg + ethambutol 400 mg) in a 40-year-old male patient with a history of drug allergy. The patient developed FDE after taking the third dose of tablet Forecox® for pulmonary tuberculosis. Tablet Forecox® was withdrawn and the patient recovered from the reaction after 15 days of treatment for FDE. As per World Health Organization-Uppsala Monitoring Centre (WHO-UMC) and Naranjo causality assessment criteria, the association between the reaction and tablet Forecox® was possible and probable, respectively. The reaction was moderately (Level 4b) severe according to the Modified Hartwig and Siegel scale. As there is an increased risk of allergic reaction in patients with a history of drug allergy, FDCs should not be used in order to avoid complexity in identifying the culprit drug.
