    Prednisolone structure


    Prednisolone's anti-inflammatory effects can be mediated by reducing cellular adhesion molecule (CAM) expression. Prednisolone (0.75 mg/kg) reduces macrophages (-59%, -57%), CD4( ) T-cells (-50%, -60%), CD8( ) T-cells (-58%, -48%), and eosinophils (-36%, -25%) in quadriceps and soleus muscles, respectively. Prednisolone-treated mice also exhibits decreased vascular P-selectin (-82%) and ICAM-1 (-52%) expression and fewer L-selectin (-79%) and ICAM-1 (-57%) expressing mononuclear cells in quadriceps. Prednisolone reduces sarcolemmal damage and degeneration as well in Dystrophin-deficient, mdx mice. Prednisolone (5 mg/kg) causes alterations in diaphragmatic contractile properties and histological changes without fiber atrophy in rats. Prednisolone results in an increased number of diaphragmatic bundles in rats. Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. , R′ = H; Depo-Medrol) are poorly water-soluble corticosteroid drugs. To permit aqueous injection or ophthalmic delivery of these drugs, they must be converted into water-soluble forms, such as one of the ionic esters described in Section . However, there are two considerations in the choice of a solubilizing group: the ester must be stable enough in aqueous solution so that a ready-to-inject solution has a reasonably long shelf life (greater than 2 years; half-life about 13 years), but it must be hydrolyzed in vivo with a reasonably short half-life after administration (less than 10 min). For this optimal situation to occur, the in vivo Na; Solu-Medrol). However, the in vitro stability is low, probably because of intramolecular catalysis; consequently, it is distributed as a lyophilized (freeze-dried) powder that must be reconstituted with water and then used within 48 h. The lyophilization process adds to the cost of the drug and makes its use less convenient. On the basis of physical-organic chemical rationalizations, a series of more stable water-soluble methylprednisolone esters was synthesized, and several of the analogs were shown to have shelf lives in solution of greater than 2 years at room temperature.

    The difference between prednisone and prednisolone is that one is the precursor to the other. Prednisone is activated by enzymes in the liver to turn into prednisolone. They do have similar uses but prednisolone is more readily absorbed by the body. Prednisolone is usually used when there is liver toxicity or liver failure involved. Although they have many similarities, there are some differences between these two substances. For one, the do have a different chemical structure and molecular weight. Also, prednisone is administered only orally, whereas prednisolone can be given orally or topically or even injected if necessary. Adrenal cortical atrophy develops during prolonged therapy and may persist for years after stopping treatment. Withdrawal of corticosteroids after prolonged therapy must therefore always be gradual to avoid acute adrenal insufficiency, being tapered off over weeks or months according to the dose and duration of treatment. During prolonged therapy any intercurrent illness, trauma or surgical procedure will require temporary increase in dosage; if corticosteroids have been stopped following prolonged therapy they may need to be temporarily re-introduced.3. Undesirable effects may be minimised by using the lowest effective dose for the minimum period and by administering the daily requirement as a single morning dose or whenever possible as a single morning dose on alternative days. Frequent patient review is required to appropriately titrate the dose against disease activity.4. Care and frequent patient monitoring is necessary in patients with the following complaints: diabetes mellitus (or a family history of diabetes), osteoporosis (post-menopausal women are particularly at risk), hypertension, congestive heart failure, patients with a history of severe or pre-existing affective disorders (especially a history of steroid psychosis), glaucoma or a family history of glaucoma, previous corticosteroid induces myopathy, epilepsy, liver failure, renal insufficiency or peptic ulceration.5. Suppression of the inflammatory response and immune function increases the susceptibility to infections and their severity.

Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. The relative potency of corticosteroids depends on the molecular structure, concentration, and release from the vehicle. INDICATIONS AND USAGE
