About Viagra

Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH). It was originally developed by British scientists and then brought to market by the US-based pharmaceutical company Pfizer. It acts by inhibiting cGMP-specific phosphodiesterase type 5, an enzyme that delays degradation of cGMP, which regulates blood flow in the penis. Since becoming available in 1998, sildenafil has been the prime treatment for erectile dysfunction; its primary competitors on the market are tadalafil (Cialis) and vardenafil (Levitra).

The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now standard treatment for erectile dysfunction in all settings, including diabetes. People on antidepressants may experience sexual dysfunction, either as a result of their illness or as a result of their treatment. A 2003 study showed that sildenafil improved sexual function in men in this situation. Following up to earlier reports from 1999, the same researchers found that sildenafil was able to improve sexual function in female patients on antidepressants as well.

  • Drug Name

    Retin-A (Tretinoin) 

    Drug Uses

    Retin-A is often used to improve the appearance and texture of the skin. It produces a mild, superficial peel of the epidermis. Retin-A has effects on the both the superficial (epidermis) and the deep (dermis) parts of the skin. The major benefit is to decrease the effects of sunlight caused aging by increasing the speed with which the surface cells are replaced. 

    How to use

    Apply a thin layer to affected area once a day at bedtime. Use a gauze pad or cotton swab to apply the liquid. Wash your hands immediately after use. Using this medication more frequently or in excessive amounts does not improve the results, but may increase side effects. Avoid applying near the eyes, mouth, or open cuts since this medication can irritate sensitive skin. Acne may appear to worsen when the medication is first used; continue therapy. It may take three to six weeks before the full benefits of this medication are seen. Use mild soap when washing your face. Do not wash face excessively. Abrasive soaps, cleansers, medicated creams or lotions can increase skin irritation. Consult your doctor or pharmacist about their use. Use other acne preparations with caution while using this medication. 


    Drug Class and Mechanism

    Tretinoin is a derivative of vitamin A. Topical Tretinoin is used in the treatment of mild to moderate acne and on skin that has been damaged by excessive exposure to the sun. Tretinoin irritates the skin and causes the cells of the skin to grow (divide) and die more rapidly, that is, it increases the turnover of cells. The number of layers of cells in the skin actually is reduced. In patients with acne, new cells replace the cells of existing pimples, and the rapid turnover of cells prevents new pimples from forming. By a similar mechanism, Tretinoin can reduce some wrinkles, areas of darkened skin, and rough areas of skin, all of which occur in sun-damaged skin. In patients with sun-damaged skin, improvements in the skin usually are seen within the first 3 to 4 weeks of treatment. Brown spots begin to fade after six to eight weeks. Wrinkles decrease or disappear after three to six months. Following application to the skin, a minimal amount of drug is absorbed into the body. 


    Missed Dose

    If you miss a dose, use it as soon as remembered; do not use if it is almost time for the next dose, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up. 


    Storage

    Store at room temperature away from sunlight. Keep this and all medications out of the reach of children.

  • Warnings/Precautions

    This medication can increase sensitivity to sunlight, wind and cold. Avoid prolonged exposure to the sun and sunlamps. Wear protective clothing and use an effective sunscreen. This medication should be used during pregnancy only if clearly needed. It is not known if Retin-A appears in breast milk. Consult your doctor before breast-feeding.

  • Possible Side Effects

    Due to the possibility of irritation, it is advisable to begin treatment on a small area of skin. Exposure to the sun or to ultraviolet rays causes additional irritation. During treatment, such exposure should be avoided as much as possible or a sun block should be used. During the first weeks of treatment there may be an apparent worsening of the problem. Such a reaction is perfectly normal because small cysts deep within the skin are being eliminated at an accelerated rate. This medication can increase sensitivity wind and cold. Avoid prolonged exposure to the sun and sunlamps. Wear protective clothing and use an effective sunscreen. If any ingredient should cause hypersensitivity, discontinue use.
