Description

Cialis, containing the active ingredient tadalafil, is primarily used to treat two conditions in men: Erectile Dysfunction (ED) and Benign Prostatic Hyperplasia (BPH). The specific product in question is a 6-count card of 20 mg tadalafil tablets, which is a common dosage for these treatments.

Purpose

• Erectile Dysfunction (ED): Tadalafil enhances blood flow to the penis, facilitating firmer and longer-lasting erections. Its effects can last up to 36 hours after ingestion, making it suitable for use as needed or in a daily low-dose regimen.
• Benign Prostatic Hyperplasia (BPH): Tadalafil can alleviate urinary symptoms associated with an enlarged prostate by relaxing muscles in the prostate and bladder, improving urine flow.

Dosage and Administration

• Tadalafil is available in several strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg. For ED, it can be taken:
  • As needed: Typically, 10 mg before sexual activity, adjustable to a maximum of 20 mg.
  • Daily: Starting at 2.5 mg or 5 mg, taken at the same time each day.
• For BPH, the recommended dosage is usually 5 mg daily.

• Key Benefits

  1. Erectile Dysfunction Treatment:
     • Cialis enhances blood flow to the penis, facilitating firmer and longer-lasting erections. Its effects can last up to 36 hours, making it suitable for use as needed or in a daily low-dose regimen.
  2. Benign Prostatic Hyperplasia Relief:
     • It helps relax the muscles in the prostate and bladder, improving urinary flow and reducing symptoms related to BPH, such as frequent urination and difficulty emptying the bladder.
  3. Convenient Dosing Options:
     • Available as an “as-needed” medication or a daily low-dose option, allowing flexibility based on individual needs.
  4. Long Duration of Action:
     • Tadalafil’s longer half-life compared to other PDE5 inhibitors means fewer doses are needed throughout the week.

             • Mechanism of Action

               1. Role of Nitric Oxide (NO):
                  • During sexual stimulation, nitric oxide is released in the corpus cavernosum of the penis. This release is crucial for initiating the erection process.
               2. Production of Cyclic Guanosine Monophosphate (cGMP):
                  • Nitric oxide stimulates guanylate cyclase, which converts guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP). cGMP is a key signaling molecule that promotes smooth muscle relaxation.
               3. Smooth Muscle Relaxation:
                  • Increased levels of cGMP lead to relaxation of the smooth muscles in the corpus cavernosum. This relaxation allows for increased blood flow into the penis, resulting in an erection.
               4. Inhibition of PDE5:
                  • Tadalafil selectively inhibits PDE5, the enzyme responsible for breaking down cGMP. By blocking this enzyme, tadalafil increases the concentration of cGMP in the corpus cavernosum, thereby enhancing and prolonging erectile function during sexual arousal.
               5. Effects on Other Conditions:
                  • In addition to treating erectile dysfunction, tadalafil is also used for conditions like Benign Prostatic Hyperplasia (BPH) and Pulmonary Arterial Hypertension (PAH).
                    • For BPH, tadalafil may help relax smooth muscle in the prostate and bladder, improving urinary flow.
                    • In PAH, it relaxes the pulmonary vasculature by increasing cGMP levels, leading to vasodilation and reduced pulmonary artery pressure.
               6. Dependence on Sexual Stimulation:
                  • It’s important to note that tadalafil does not cause an erection without sexual stimulation; it enhances the natural erectile response by increasing cGMP levels only when nitric oxide is present due to sexual arousal.                           
                    

                    When Not to Take Tadalafil Sandoz

                    1. Heart and Blood Vessel Issues:
                       • Do not use Tadalafil Sandoz if you have heart problems, such as:
                         • Angina
                         • Arrhythmias
                         • Heart failure
                         • A history of heart attack (within the last 3 months)
                         • A history of stroke (within the last 6 months)
                       • Sexual activity can put extra strain on the heart, posing risks for individuals with these conditions.
                    2. Blood Pressure Concerns:
                       • Avoid if you have unusually high or low blood pressure that is not effectively treated.
                    3. Vision Loss:
                       • Do not take if you have experienced vision loss in one eye due to non-arteritic anterior ischemic optic neuropathy (NAION).
                    4. Drug Interactions:
                       • Avoid using Tadalafil Sandoz if you are currently taking:
                         • Nitrates (e.g., nitroglycerin) for chest pain, as this combination can cause a severe drop in blood pressure.
                         • Recreational drugs known as “poppers” (amyl nitrite).
                         • Guanylate cyclase stimulators like riociguat, used for pulmonary arterial hypertension.
                    5. Allergic Reactions:
                       • Do not take if you are allergic to tadalafil or any of its inactive ingredients.
