• Tadalafil 20mg Tablets (8s)

  • Tadalafil 20mg
  • Cialis tablets contain the active ingredient tadalafil, which is a type of medicine called a phosphodiesterase type 5 inhibitor. It is used to help men with erectile dysfunction to acheive and maintain an erection, and can also be used to relieve the symptoms of an enlarged prostate gland.

    Tadalafil works by preventing the action of a chemical in the body called phosphodiesterase type 5.

    An erection is produced via a complex chain of events, involving signals from the nervous system and the release of chemical messengers within the tissues of the penis. One of these chemical messengers is called cyclic GMP.

    Cyclic GMP causes the blood vessels in the penis to widen by relaxing a thin layer of muscle found in the blood vessel walls. This allows more blood to enter the penis, which ultimately results in the penis becoming rigid and erect. Cyclic GMP is normally broken down by another chemical in the body called phosphodiesterase type 5.

    Tadalafil works by preventing the action of phosphodiesterase type 5, thus stopping the breakdown of cyclic GMP. This means that the blood vessels are kept dilated for longer, which improves blood flow to the penis and helps maintain an erection.

    As tadalafil only enhances the actions of the chemical messengers responsible for producing an erection, it will only work once these messengers are released in the penis. This means that sexual stimulation is required for it to produce and maintain an erection.

    Tadalafil's effect on the blood vessels also improves blood flow to the prostate gland. The prostate gland lies at the top of the tube connecting the bladder to the outside (urethra). The prostate gland often enlarges with advancing age, pressing on the urethra and obstructing the flow of urine from the bladder. This condition, called benign prostatic hyperplasia, can cause various urinary symptoms, such as weak urine flow, difficulty passing urine and frequently needing to pass urine.

    By improving the blood flow to the prostate, and also relaxing the muscle in the prostate gland and the bladder, tadalafil helps to relieve these urinary symptoms.

    Cialis tablets may be taken with or without food. The tablets should be swallowed whole with a drink of water.

    Cialis 10mg and 20mg tablets are intended for use on an 'as needed' basis for erectile dysfunction. With these strength tablets the dose should be taken at least 30 minutes before intended sex. One dose can produce an erection in response to sexual stimulation for up to 36 hours. These tablets should be taken no more than once a day, and should not be taken every day on a continuous basis.

    If Cialis 10mg or 20mg tablets work for you, but you anticipate taking Cialis on a regular basis (to have sexual activity at least twice a week), Cialis once-a-day tablets may be an appropriate option for you. These tablets contain a lower dose of tadalafil (2.5mg or 5mg) and are designed to be taken once a day, every day, allowing you to get an erection and have sex whenever you wish. Cialis 2.5mg and 5mg tablets should not be taken more than once a day.

    If you are taking Cialis 5mg tablets for an enlarged prostate gland, or erectile dysfunction and an enlarged prostate gland, you should take one tablet once a day, at the same time each day.
