ABSTRACT
OBJECTIVE: To evaluate the effect of a new oral contraception formulation with drospirenone (Yasmin) on vital signs, complete blood count, glucose, electrolytes, and renal and liver function. MATERIAL AND METHOD: An open-label non-comparative clinical trial was conducted. One hundred women who were planning to use oral contraception for at least six months were recruited. The subjects received a blister pack which contained 21 tablets of 3 mg drospirenone /30 tg ethinyl estradiol for the first four cycles (1 cycle = 28 days). Cycle 5 and 6 blister packs were dispensed during the visit in cycle 4. Heart rate and blood pressure of each subject were checked at baseline and each visit. Serum from each subject was collected and sent for complete blood count, glucose, electrolytes, and renal and liver function tests at baseline and at cycle 6. Mean differences in these tests at cycle 6 compared to baseline were assessed. RESULTS: Ninety-two of the 100 subjects (92%) completed the present study. There was no significant change in heart rate, blood pressure, complete blood count, glucose, electrolytes, and renal and liver function tests at cycle 6 when compared to baseline. CONCLUSION: Oral contraception formulation with drospirenone (Yasmin) is well tolerated and has good contraceptive efficacy. It is safe, as it has no effect on heart rate, blood pressure, complete blood count, glucose, electrolytes, and renal and liver function.

BACKGROUND: Oral contraceptive is the most commonly used method of fertility control. Yasmin is a combination of a novel progestogen with anti-androgenic and anti-mineralcorticoid activities (3 mg Drospirenone (DRSP) and 30 microg ethinylestradiol (EE)). It has been shown in many clinical trials that Yasmin is an efficacious oral contraceptive, lacking undesired effects as with other oral contraceptives such as weight gain. However the effects of Yasmin on sexual desire and libido have not been intensively investigated so far OBJECTIVE: Investigate the effects of Yasmin on sexual desire, libido and changes in the free androgen index (FAI) compare to Meliane (75 microg gestodene + 20 microg ethinylestradiol). MATERIAL AND METHOD: The authors' report the results of a double blind randomized controlled study using a translated version of the Female Sexual Function Index questionnaire (FSFI) for the assessment of the sexual function. The free androgen index was calculated from measurements of testosterone and sexual hormone binding globulin. RESULT: The result shows statistically significant improvements regarding sexual desire, arousal and overall satisfaction in the Yasmin group. Additionally, an increased frequency of orgasms in the Meliane group was reported. Statistically significant differences between the two treatments regarding changes in the FSFI score and changes in the free androgen index have not been observed. CONCLUSION: The novel oral contraceptive containing drospirenone (Yasmin) and the non-anti-androgenic progestin containing oral contraceptive (Meliane) do not show unfavorable effects on sexual response and libido.

Decrease in cholesterol was observed in precataractous, cataractous, advance nuclear cataractous and non-cataractous lenses when 3 beta-(2-diethylaminoethoxy)-androst-5-en-17- oneHCl (U18666A) was injected, sc, to rats. Significant increase in lipid peroxidation was observed before the onset of any apparent lenticular opacity in U18666A treated rats. The results suggest that decrease in cholesterol is capable of altering the structural integrity of lens fibers. However, 12.5% decrease in cholesterol and 5% increase in lipid peroxidation observed in non-cataractous lenses indicated that these changes are not sufficient for any apparent opacification.

The effect of chandonium iodide (as a non-depolarising muscle relaxant) was studied in 50 patients of ASA grade I or II who were scheduled for surgery. The patients were divided into 2 groups according to the dose of chandonium iodide (0.2 and 0.25 mg/kg respectively). The onset and duration of action was found to be dose dependent. Intubation characteristics were good to fair in all the patients, the reaction to intubation being either absent or mild. There was mild and transient rise in pulse and blood pressure. No allergic reaction was observed in any patient and reversal characteristics were good in all the cases.
