Erectile dysfunction problems worry millions of men around the world. However, the pharmaceutical industry has developed many types of drugs that are aimed at improving the quality of sexual life. Each of these drugs has its own unique characteristics.
Most erectile function improving drugs are taken orally in the form of tablets. Nevertheless, there are also drug formulations, which are intended to be used as an injection, and even sprays. However, in most cases, drugs dispensed as tablets are much more convenient because injections cannot always be administered immediately prior to sexual intercourse.
For many years, Viagra has been considered the most powerful stimulant of male erection. It should be taken 30–40 minutes before the planned sexual intercourse. Valid for 7–10 hours.
This medicine has its drawbacks. First of all, it has an impressive list of contraindications. Blue tablets for erectile functionality cannot be taken on an empty stomach or in case of an ulcer because the drug is capable of provoking gastrointestinal diseases (gastritis, erosion). You cannot take the erection stimulant with alcohol, as it threatens a strong increase in blood pressure and, as a result, impaired cardiac function.
Just like Viagra, Cialis needs to be taken half an hour before the planned sex. But in this case, the medicine’s effect lasts much longer than the famous blue pill. Men will observe an improvement of erectile function after Cialis for 36 hours.
Of course, there are some contraindications. The most important prohibitions on the use of Cialis are problems with the cardiovascular system (since the drug for erectile dysfunction contributes to increased blood pressure).
Levitra is the third drug considered to be the best medicine for male erectile dysfunction. Unlike its competitors, Levitra begins to act much faster. Only 20 minutes after taking the pill, a man can experience a powerful erection. But here, the duration of the effect is slightly lower, so improvement will be observed for about 4 hours.
Kamagra is the most popular analog of Viagra, as it costs less for the same quality. The drug allows males to achieve an erection and then keep it much longer than usual, which is necessary for full sexual intercourse. For maximum effectiveness, sexual arousal is required.
Kamagra is produced in the form of diamond-shaped tablets with a dosage of 100 mg. The medication should be taken 30 minutes before possible sexual intercourse. The effect of the drug persists for several hours. The recommended first dose for men is 50 mg. The maximum daily dose of the drug is one tablet per day.
Differences between generic Viagra and the original drug are nominal. The effectiveness of generic compared with original Viagra does not differ. Generic Viagra is available to consumers in dosages of 25, 50, or 100 mg to which tablets contain the same active ingredient, sildenafil, as the original.
