Are erectile dysfunction pills safe for men with heart disease?
Samples of about 1.0 g were weighed using a balance (Precisa, Switzerland) and were placed into individual beakers.
8.4 Pediatric Use
It may exacerbate conditions in people who already have an existing illness and also may cause drug–drug interactions in people who are taking pharmaceutical drugs concurrently. The Malaysian laws on poisons and sale of drugs [5] are gazetted to convict peoples who offend these laws to protect the Malaysian society from becoming victims of irresponsible persons. Most of the traditional medicines and dietary supplements available in the Malaysia market are imported from other countries either by legal or illegal channel. Some of them are being manufactured locally. Enforcement officers can raid any premises that are suspected of selling or manufacturing adulterated products and seize any suspected products found there.

At the custom point of entry, the enforcement officers need to approve and ensure that all imported drugs comply with the Malaysian Drug Control Authority requirement before being released to the market. One of the requirements is that any unregistered or registered traditional or dietary supplement products which consist of any undeclared poisons or substances that may be harmful to consumers should be seized. Under section 4, regulation 3 of Sales of Drug Act 1952, it clearly stated that the owner of premises, consignor, consignee or agent of the owner of products seized may redeem their product after 48 h if it has been confirmed that seized products are free from adulteration. Through our literature search, we found studies using differential scanning calorimetry (DSC) to detect drug in pharmaceutical products [6] as well as to analyse the stability of active ingredients in formulations [7, 8]. DSC method is also used to detect adulteration in foods materials such as honey to ensure its authenticity [9]. About 20 mL of deionised water was poured into the beakers, and the mixtures were sonicated for 15 min.

4.2 Hypersensitivity Reactions
This medicine increases the time it takes to ejaculate and improves control over ejaculation. This helps to relieve the anxiety or frustration about fast ejaculation. Sildenafil is used to treat men who have erectile dysfunction (also called sexual impotence). DR .SIDDHARTH (CEO & TREATMENT ADVISOR) K T Agencies4th Floor, Ganjipeth, Shop No 412, R Sandesh Dawa Bazaar Haj House, Central Avenue, Ganjipeth, Berar, Trading Company Nagpur - 440018, Maharashtra, India Adulteration of drugs is a serious issue and can have a great impact on human health. It is mainly done with the intention of boosting the effects of products.
What should I do if I miss a dose of sildenafil?
For many years, the enforcement officers in Malaysia have had difficulty deciding whether some products should be confiscated as they have not been able to produce fast reliable evidence of adulteration. For that reason, we explored the use of differential scanning calorimetry (DSC) as a potential fast detection method of commercial products marketed in Malaysia that may be adulterated. We confirmed the outcomes qualitatively with high pressure liquid chromatography. DSC was set at a heating rate of 10 °C min−1 and within a temperature range of 100–250 °C with nitrogen as a purge gas at a flow rate of 20 mL min−1 to analyse a sildenafil reference standard (RS), sildenafil tablets and sildenafil adulterated commercial products. Four sildenafil adulterated commercial products were analysed. LLE using a chloroform solution was performed twice on the sample solutions.
- Sildenafil tablets LP 100 mg helps maintain an erection during sexual activity.
- Its effectiveness varies among individuals; some may need different doses.
- Regular exhaustion or health issues could affect medication results.
The extracts were filtered through filter papers grade 480 (Sartorius Stedim, USA) and were collected in individual evaporating dishes. The extracts were allowed to evaporate until dry at ambient temperature.
| Drug Class or Name | Effect on Sildenafil | Possible Outcome |
|---|---|---|
| Nitrates | Potentiate vasodilation | Risk of severe hypotension |
| Alpha-blockers | Enhanced blood pressure lowering | Caution advised, dose adjustments needed |
| CYP3A4 inhibitors (e.g., Ketoconazole) | Decrease sildenafil metabolism | Increased risk of side effects |
| Blood pressure medications | Additive effects | Monitor blood pressure closely |
Each dried samples was diluted in about 5 mL of diluents and filtered
2. Revatio
The thermal behaviour of pure honey and pure syrups were determined and any differences of the thermal peak due to adulteration was detected and studied. In addition, DSC technique had also been used in other adulteration studies such as detection of adulteration in olive and virgin coconut oils [10, 11] and also detection of water adulteration in butter [12]. However, we could not find any article on the use of DSC in adulteration of pharmaceutical products. In this study, DSC will be used as a fast method of detecting adulteration of sildenafil in commercial product samples so that, decisions on confiscation of adulterated commercial product can be made within 48 h. A qualitative high pressure liquid chromatography (HPLC) analysis will also be carried out on the same samples for comparison.
What does VIAGRA (Brand for SILDENAFIL CITRATE) look like?
Reference standard of sildenafil citrate (Sildenafil RS) was purchased from Sigma Aldrich, USA. Lactose monohydrate was purchased from Aplab Saintifik, Malaysia whilst commercial products that were suspected of adulteration were obtained through the Malaysian National Pharmaceutical Control Bureau (NPCB). A coding system was used to identify and recognise samples for analysis. All sildenafil pricing samples were coded as in Table 1. Perkin Elmer DSC 6000 (USA) used in this study was calibrated with zinc and indium. using a membrane filter with a pore size 0.45 μm before HPLC analysis.
8.5 Geriatric Use
Samples were weighed using microbalance (Mettler Torledo, Switzerland) in the range of 0.5–1.0 mg and 40-μL standard aluminium pans with lids were used. The DSC was programmed through the Pyris software (Perkin Elmer, USA) to heat the samples from 100 to 250 °C at a heating rate of 10 °C with nitrogen as a purge gas at a flow rate of 20 mL min−1. Adulterated commercial products were also used as a base and were spiked with about 30 and 50 % w/w sildenafil RS to confirm the presence of sildenafil in the mixture. A qualitative HPLC analysis was performed using the NPCB in-house method for screening of sildenafil. A rapid resolution liquid chromatography (RRLC) 1200 series (Agilent, USA) with a photo-diode array detector (Agilent, USA) and an Agilent reversed-phase column of Zorbax Eclipse XDB-C8 with dimensions of 4.6 mm × 150 mm and a particle size of 5 μm for separation were involved in this experiment.
Revatio for Oral Suspension
The mobile phase was prepared using acetonitrile HPLC grade (Fisher Scientific) and deionised water (1:1) to which 1 mL of trifluoroacetic acid HPLC grade (Fisher Scientific) was added. The chromatographic condition was designed with a flow rate of 0.8 mL min−1, back pressure of 54 bar and the wavelength of photo-diode array detector was 254 nm at a temperature of 25 °C. Data analysis was done using Agilent Lab Adviser software. Sildenafil RS (Sigma Aldrich, USA) was diluted with the diluents to a concentration of 0.03 mg mL−1 and was filtered through a membrane filter with a pore size of 0.45 μm into a vial for HPLC analysis. All the adulterated commercial products were extracted using the liquid–liquid extraction method (LLE) to remove any debris that may be present in the sample mixtures. The thermal characteristic of the sildenafil RS (sample A1) obtained was found to be almost
Results and discussion
Since the melting point of sildenafil in the mixture tended to shift, the presence of sildenafil in three of these adulterated commercial products was confirmed using the spiking method and was re-analysed using DSC. The re-analysed results indicated that the enthalphy oral sildenafil of fusion (∆H) and the resolution peak of sildenafil increased accordingly depending upon the amount of spiked sildenafil RS. Apart from these results, the DSC curves also showed different patterns for sildenafil RS and the mixtures. Therefore, we concluded that DSC can potentially be used to detect sildenafil in adulterated commercial products. Currently, there are many commercial products such as herbal preparations, health foods and dietary supplements available in the market.
What are the most common side effects of sildenafil?
Most of these preparations seem to be popular among people who believe that products sourced from nature may give better health outcomes without any serious side effects as compared to modern pharmaceutical preparations [1]. They also believe dietary supplements are necessary as an additional element required by the body to enhance body functions and health. Unfortunately, these were only assumptions that natural products are safe. A number of studies done proved that these herbal preparations, health foods and dietary supplements were adulterated by other active pharmaceutical ingredients and synthetic drugs such as anti-obesity and sex stimulant agent [2–4]. Adulteration of drugs is an illegal practice, since it may be dangerous for the health of consumers as the ingredients and the dosage of drugs are unknown. the same as in a previous study [13] with a melting onset (T m) of
- Sildenafil LP 100 mg may interact with nitrate medications.
- Do not use sildenafil tablets LP 100 mg if allergic to sildenafil.
- Report any severe side effects such as prolonged erection immediately.
