Investigation of Oral Contraceptives
Investigation of ad-lib Contraceptives ad-lib ContraceptivesMade byLAB GROUP C2Lab Instructors A.L/ Ahmed Refaat abjure 2015Oral ContraceptionContraception can be defined as the method of barroom of pregnancy also referred to as Birth bear medication. Mainly contraceptives be composed of hormones thus, referred to as hormonal contraceptives they consist of artificial sex hormones female based hormones much(prenominal) as estrogen or progestin. Their mechanism of action is to block the process of ovulation hence, nixing pregnancy.Methods of contraception in that respect ar a lot of contraception methods theyre mainly divided into physical-mechanical or chemic methods. Physical-mechanical methods includeCaps it is a thin soft silicone prevents sperm keenness by cove promise the cervix.Male and female condomsContraceptive Implants flexible and slight forty mm long tube. A trained professional commonly inserts the implant it stops the release of eggs from the ovary.Diaphrag ms placed indoors the vagina in the lead intercourse, it covers the cervix as well.IUD T-shaped intrauterine device placed interior the womb by a specialized professional it terminates sperms and eggs in the fallopian tube or womb.IUS plastic T-shaped intrauterine system placed within the womb by a physician, it releases progestogen (steroid) that thickens the mucus in the cervix making it impossible for a sperm to penetrate it.Vaginal ring a plastic soft and ring shaped placed internal the vagina, releases as well progestogen with the same cause as the IUS. inseparable family planningChemical methods includeCombined lozengesContraceptive patchesProgestogen pillContraceptive injectionThere are permanent methods of contraception such asVasectomy in malesSterilization or sealing of the fallopian tube in femalesClassification of doses is mainly based on the type of chemical or active ingredient. Oral contraceptives are classified into 3 categoriesCombination (estrogen/progestin ) spontaneous contraceptivesProgestin only based spontaneous contraceptivesEffects of different ad-lib contraceptivesOral contraceptive DrugsOrtho Micronor (Norethindrone)Drug classIt is a First propagation Progestin. It is less androgenic than second generation progestin such as levonorgestrel.Mechanism of actionOrtho Micronor is a progestin-only contraceptive oral pill. It is designed for the prevention of pregnancy by suppressing ovulation in nearly half of the users, thickening the cervical mucus to prevent sperm penetration, and the reduction of LH midcycle tops FSH, it slows the front of the ovum altering the endometrium and the fallopian tubes.Pharmacological actionProgestin oral contraceptives are used for the prevention of pregnancy.Pharmacokineticsserum progesterone levels peak later oral administration in active two hours, then through distribution and rapid elimination. In 24 hours after drug intake, serum levels are close to the base line, which sacks the effic iency depends on rigid adherence to the dosage. There are wide variations between individual users in serum levels. The results of the progestin administration lower the levels of serum progesterone balance and a shorter half life of the concomitant administration with estrogens.ContraindicationsCarcinoma of the chestsuspected pregnancyHypersensitivity to any factor of this productliver diseaseDrug interactions Thyroxine concentrations inevitably descend eventually, because there is a decrease in main binding thyroidal globulinThe efficacy of pills that are progestin based only is suppressd by the (HEID) or hepatic enzyme-inducing drugs for example carbamazepine, anticonvulsants phenytoin, and the antiatomic number 65 drug rifampin and barbiturates. positioning-effectsVomiting, malady, bloating, Vaginal bleeding, troublePlan B (levonorgestrel)Drug class Second Generation progestin. apply worldwide and FDA approves as plan B. It has high androgenic effects.PharmacokineticsNo finical examination of irrefutably for the bioavailability of plan B (levonorgestrel) in people has been directed. Be that as it may, writing demonstrates that levonorgestrel is quickly and totally assimilated after oral organization (bioavailability somewhat 100%) and is not subject to first pass digestion system. After a solitary measurements of Arrangement plan B (levonorgestrel) (0.75 mg) regulated to 16 ladies tweakstairs fasting conditions, greatest serum centralizations of levonorgestrel are 14.1 7.7 ng/mL (mean SD) at a normal of 1.6 0.7 hours.Pharmacological action Plan B is proposed to exclude pregnancy after known or suspected prophylactic mortification or unprotected intercourse.Mechanism of actionCrisis contraceptives are not roaring if the lady is now pregnant. Plan B (levonorgestrel) is accepted to go about as a crisis prophylactic essentially by avoiding ovulation or cookery (by modifying tubal transport of sperm and/or ova). Whats more, it may hinder imp lantation (by modifying the endometrium). It is not successful once the methodology of implantation has started.Side effectsNauseaHeadacheBreast tendernessFatigueVomiting abdominal muscle painDiarrheaContraindicationsIt is not prescribed for utilization in the come with conditionsKnown or suspected pregnancyHypersensitivity to any segment of the drugDrug interactionsHypothetically, the adequacy of low-measurement progestin-just pills is diminished by hepatic catalyst instigating medications, for example, the anticonvulsants carbamazepine, phenytoin, anti- tuberculosis and barbiturates.Yasmin (drospirenone/ethinyl oestradiol)Drug class Third generation oral contraceptive. It is mostly disliked due to dangerous side effects.PharmacokineticsIrrefutably the bioavailability of DRSP from a solitary element contraceptive pill is around 76%. Unquestionably the bioavailability of EE is pretty nearly 40% as a consequence of presystemic conjugation and first-pass digestion system. Indisputa bly the bioavailability of Yasmin, which is a mix pill of EE and DRSP, it has not been assessed. Serum convergances of DRSP and EE arrived at top levels inside 1-2 hours after organization of Yasmin.PharmacodynamicsPharmacodynamic studies were not conducted specifically with Yasmin.Therapeutic useYasmin is demonstrate for utilization by ladies to avert pregnancy.Mechanism of actionCOCs bring down the risk of getting to be pregnant basically by surround ovulation. Other conceivable components may incorporate cervical bodily bland changes that restrain sperm entrance and endometrial changes that decrease the probability of implantation.Side effectsIrregular uterus bleedingHeadacheNausea coloured diseaseBreast tendernessContraindicationsDont endorse Yasmin to ladies who are known to take the accompanyingRenal impedanceAdrenal deficiencyHypertension concord breast cancer form coronary vein illnessHave thrombogenicvalvular or thrombogenic mood illnesses of the heart (for instance, s ubacute bacterial endocarditis with valvular malady, or atrial fibrillation)Have Diabetes mellitusDrug interactionsSubstances reducing the viability of COCs Medications or home big items that incite certain chemicals, including cytochrome P450 3A4 (CYP3A4), may diminish the adequacy of COCs or mannequin achievement dying.Effects of Joined Oral Contraceptives on Different Medications COCs containing EE may hinder the digestion system of different mixes.Potential to Build Serum Potassium Focus There is a potential for an increment in serum potassium fixation in ladies bringing Yasmin with different medications.Mircette (desogestrel/ethinyl estradiol and ethinyl estradiol) Second generation Mechanism of actionThe mechanism of action of it full treatment over four directionssuppression of the gonadotropinsalteration changes in the mucus which make it hard and difficult to the sperm to entire the uterusThe endometrial changes that reduce the likelihood of the implantation processinhib ition of ovulation from happeningPharmacokineticsThe substance desogestrel is all in all and fast absorbed then converted to the active form which is etonogestrel after taking the oral route of administration the bioavailability was measured and found close to 100% by taking serum levels of etonogestrel . Therapeutic usesIt is used to prevent the pregnancy.Side effectsVomitingGastrointestinal symptoms (such as abdominal cramps and bloating)Nauseaproblems in menstruation processBreast changes, enlargement, tenderness , and secretionContraindications old problems concerning deep vein Thrombophlebitisor thromboembolic disordersIf there is any predication for breast carcinoma or current oneDrug interactions gain in factors ix ,vii,viii,x and prothrombin levels this will cause increase in nor adrenline induced platelets accruementIncrease in other binding proteins in serum levelsIncrease in the levels of thyroid binding globulinReferencesContraceptives.
