The rules on medicines for human use come from Decree-Law 176/2006 of 30 August 2006, while the rules on medical devices come from Decree-Law 189/2000 of 12 August, Decree-Law 145/2009 of 17 June, Decree-Law 29/2024 of 5 April, Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 (the Medical Devices Regulation – MDR) and Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 (In Vitro Medical Devices Regulation – IVMDR). There are also several sets of regulations that implement decree laws in different matters.

The regulatory body responsible for applying and enforcing pharmaceutical and medical device regulations is INFARMED (the National Authority of Medicines and Health Products, IP), which is part of the State’s indirect administration and is endowed with administrative and financial autonomy. It is responsible for carrying out the Ministry of Health’s responsibilities under the supervision and guidance of the Minister of Health.

As a rule, the Minister of Health makes decisions regarding public funding for medicines and medical devices, which may delegate these decisions to Infarmed.

INFARMED’s decisions regarding medicines and medical devices may be challenged through administrative and/or judicial channels within a given period.

Individuals and companies affected by these decisions can challenge them, mainly on the grounds of:

• breach of the law;
• errors of fact;
• errors of law; and
• breach of procedural requirements.

These means of reaction are common to decisions that affect other products (eg, food supplements and cosmetics), although there may be specific details.

Certain categories of medicines and medical devices are subject to specific regulations. For example, medicines containing psychotropic and narcotic substances are regulated by:

• Decree-Law 15/93 of 22 January 2022;
• Decree-Regulation 61/94 of 12 October 1994;
• Law 33/2018 of 18 July 2018; and
• Decree-Law 8/2019 of 15 January.

In addition, some medicines, in addition to being prescription-only, are subject to further restrictions, such as those for hospital use only.

Medical devices and IVMD are also subject to different classifications depending on their risk and the need for monitoring by healthcare professionals.

Different pieces of legislation regulate clinical trials of medicines and clinical studies of medical devices.

Medicines

Regulation regulates clinical trials of medicines (EU) 536/2014 of the European Parliament and of the Council of 16 April 2014 (“Clinical Trials Regulation”) and Law 21/2014 of 16 April 2014 (“Clinical Trials Law”).

The entry into force of the Clinical Trials Regulation on 31 January 2022 also introduced the Clinical Trials Information System (CTIS), through which all clinical trial submission, assessment and supervision processes in the EU are to be submitted. The three-year transition period under the Clinical Trials Regulation has elapsed on 31 January 2025, after which all ongoing trials must be transferred to the CTIS.

Medical Devices

The rules regarding clinical studies of medical devices are found in the MDR, as implemented in Decree-Law 29/2024 in Portugal.

In addition, Law 71/2025 of December 22 introduced a set of provisions into Portuguese law to implement MDR for clinical investigations and performance studies of medical devices.

In Vitro Medical Devices

The legal rules applicable to clinical studies of in vitro medical devices are established in IVMDR and in the Clinical Trials Law.

In addition, Law 71/2025 of December 22 introduced a set of provisions into Portuguese law to implement IVMDR, including provisions on clinical investigations and performance studies of IVMD.

Medicines

Since 31 January 2025, authorisation to conduct a clinical trial of medicine needs to be obtained through the CTIS, pursuant to the Clinical Trials Regulation.

Applications for clinical trials in the EU and the European Economic Area must be submitted under the CTIS, under the terms provided by Regulation (EU) 536/2014 of the European Parliament and of the Council of 16 April 2014 on clinical trials of medicinal products for human use. In this case, applications must be submitted through the CTIS, and the sponsor should propose a reporting member state responsible for analysing the application.

Medical Devices

Applications to conduct clinical investigations as defined in the MDR must be submitted by the sponsor to the member state(s) where the clinical investigation will be conducted. The application must be submitted through the electronic system referred to in the MDR, accompanied by the documents referred to in Chapter II of Annex XV of the MDR.

Clinical trials of medicines and clinical studies of medical devices are available on the National Clinical Trials Register website at www.rnec.pt. The results of clinical trials and clinical studies of medical devices are not available in publicly accessible databases.

Access to clinical trials of medicines is also available on CTIS, where results from completed trials are already available (www.euclinicaltrials.eu).

The recruitment methods for clinical trials of medicines and clinical studies of medical devices must follow the legally prescribed rules. In addition to physical advertising methods, digital means can be used for this purpose. These means may also be used for monitoring purposes, provided they do not jeopardise the trial’s purpose and safety.

Data from clinical trials of medicines and clinical studies of medical devices may qualify as sensitive personal data. However, if the data is fully anonymised (and not merely pseudonymised), it is no longer personal data and therefore does not fall within the category of sensitive data. Anonymisation implies that the data subject’s identity is unobtainable, which makes the data anonymous.

If the data resulting from processing is still classified as personal data, it may be shared with third parties or affiliates. However, this transfer must adhere to the requirements of the General Data Protection Regulation (GDPR). This includes obtaining consent, fulfilling information obligations, ensuring the security of the processing, establishing joint controllership or sub-processing agreements, and complying with regulations regarding international data transfers. If the resulting data is anonymised, then those GDPR requirements do not apply.

The GDPR requirements regarding the processing of health data apply to the grounds for lawfulness, transparency and security measures.

Products are classified through the definition of medicine (function and/or presentation) and the definition of medical device provided in the applicable legal provisions. In the case of borderline products, the purpose intended by the manufacturer of the product in question and the mechanism through which the main desired effect is achieved are considered.

Regarding other borderline situations (medicines and cosmetics, or medicines and food supplements), the function and/or presentation are also considered.

Medicines developed by means of one of the following biotechnological processes must be subjected to the centralised community procedure:

• recombinant DNA technology.
• controlled expression of genes coding for biologically active proteins in prokaryotes and eukaryotes, including transformed mammalian cells.
• hybridoma and monoclonal antibody methods.

The following medicines are also subject to centralised procedures:

• advanced therapy medicinal products; and
• medicinal products for human use containing a new active substance for which the therapeutic indication is the treatment of any of the following diseases: AIDS, cancer, neurodegenerative disorder, diabetes, autoimmune diseases and other immune dysfunctions and viral diseases.

Medicines

For medicines, the MA is valid for five years; after the first renewal, it is valid indefinitely or, if deemed necessary, for a second five-year period. The renewal of the MA is subject to a specific renewal procedure.

MA may be revoked, suspended or amended whenever there is non-compliance with the applicable legal and regulatory provisions or with the conditions of the MA in question. This includes when it is concluded that the risk-benefit balance is unfavourable, the medicine is harmful or the manufacturing process does not comply with the applicable good practices.

Medical Devices

No authorisation is required to place medical devices on the market. The manufacturer must submit the medical device to a conformity assessment and notify the competent authority that the medical device has been made available on the market. INFARMED may withdraw a product from the market or may suspend, restrict or subject to certain conditions the placing on the market and putting into service of a device or group of medical devices under certain conditions – namely when the use of medical devices could compromise the health and safety of patients or other persons, or for public health reasons.

The marketing of a medicine may follow one of these procedures:

• a national procedure, if the medicine is intended to be approved only for placing on the Portuguese market;
• a mutual recognition procedure, in which an authorisation obtained in a Member State is used to apply for authorisation in a new Member State;
• a decentralised procedure, when the application is submitted in several Member States simultaneously and when the medicine does not have an MA in any Member State; and
• a centralised procedure managed by the European Medicines Agency (EMA), leading to an MA valid in all member states.

Any change in the terms of an MA must be subject to an application for a variation of the MA, including changes to the summary of product characteristics and any conditions, obligations or restrictions affecting the MA or changes to the labelling or package leaflet in connection with changes to the summary of product characteristics.

An MA may be transferred to a new holder by submitting a transfer application by the current MA holder.

The placement of a medical device on the market does not require authorisation (see 3.3 Period of Validity for Marketing Authorisation for Pharmaceutical or Medical Devices).

Medicines without an MA, or with an MA that is valid in Portugal, may be made available to patients through the exceptional use authorisation, under which patients can access them and/or through early access programmes, which are subject to specific regulations issued by INFARMED.

Regarding medical devices, INFARMED may authorise the placing on the market or putting into service of a medical device for which no conformity assessment procedures have been carried out, but the use of which is in the interest of public health, patient safety or health.

Compassionate use also takes place in the context of clinical trials.

The MA for a medicine may be granted subject to the subsequent conduct of additional studies or compliance with special rules regarding safety and the reporting of all incidents associated with the use of the medicine and the measures to be taken, the conduct of a post-authorisation safety or efficacy study, or the fulfilment of other obligations established by INFARMED.

After granting an MA, INFARMED may require its holder to conduct a post-authorisation safety study if:

• there are doubts about the risks of the authorised medicine; or
• knowledge of the disease or clinical methodology indicates that previous efficacy evaluations may need to be significantly revised.

The holder of an MA is required to comply with the obligations provided for by law – namely, to comply with pharmacovigilance obligations and to make this or other data proving that the benefit-risk relationship of the medicine remains favourable available to INFARMED.

Manufacturers of medical devices other than investigational devices must report any field safety corrective action to INFARMED, as well as any serious incident or any statistically significant increase in the frequency or severity of incidents that are not serious incidents or that are expected to have undesirable side effects that could have a significant impact on the benefit-risk analysis and which have led or may lead to unacceptable risks to the health or safety of patients, users or other persons.

INFARMED publishes information on the status of an MA application and its assessment report on its website. It suppresses any commercially confidential information and allows access to the summary of product characteristics, the package leaflet and information on the medical devices placed on the market.

Fast-track procedures for the registration of medicines and medical devices may be established and applied in very specific circumstances, such as those arising from the COVID-19 pandemic. However, the Portuguese regulatory framework does not generally provide for a specific fast-track mechanism for the registration of medicines and medical devices.

In the case of medicines, the applicant may submit a reasoned request for the accelerated assessment procedure, which reduces the assessment period of the application, based on a major public health interest, from the perspective of therapeutic innovation, as provided for in Regulation (EC) 726/2004 of the European Parliament and of the Council of 31 March 2004.

INFARMED has not issued authorisations based on specific Portuguese regulatory reliance rules. Nevertheless, as an EU member, Portugal is covered by the mutual recognition agreements between EU and third-country authorities concerning the conformity assessment of regulated products. Such agreements contain a sectoral annex on the mutual recognition of good manufacturing practice inspections and batch certification of human and veterinary medicines.

The manufacture of medicines, experimental medicines and medical devices requires authorisation from INFARMED.

Facilities used to manufacture medicines must be specifically licensed for that purpose and are required to comply with good manufacturing practices. The facilities are subject to periodic inspections by INFARMED, which certifies their compliance and issues a certificate of good manufacturing practices, valid for three years.

For medical devices, facilities must obtain an industrial activity licence in accordance with the applicable legislation and have an industrial activity code associated with the categories of medical devices produced in conjunction with the respective manufacturing activities performed.

INFARMED issues authorisation for the wholesale of medicines. It covers supplying, holding, storing, or delivering medicines for processing, resale, or use in medical services, healthcare facilities, and pharmacies, excluding the supply to the public. It specifies the facilities from which distribution is carried out and is subject to the validity of the certificate of good distribution practices, which must be renewed every five years.

The wholesale of medical devices is subject to prior notification to INFARMED. It covers supplying, holding, storing or supplying medical devices for resale or use in medical services, healthcare facilities, pharmacies and other points of sale to the public, excluding supply to the public.

MA Holders can be granted a simplified registration to distribute their own medicines through authorised third-party logistics operators.

For dispensing to the public, medicines are classified into prescription-only medicines (MSRMs) and non-prescription medicines (MNSRMs). The former can also be classified as renewable, special or for restricted use in specialised monitored conditions and the latter as MNSRMs for dispensing only in pharmacies.

The import and export of medicines is regulated by Decree-Law 176/2006 of 30 August 2006 and by related legislation on good practice in transportation and distribution. The MDR and Decree-Law 29/2024 apply to medical devices.

INFARMED is the entity responsible for monitoring compliance with these regulations.

Any natural or legal person can be an importer of medicines and medical devices if they are duly authorised and licensed for that purpose by INFARMED.

The import and export of medicines and medical devices require the economic operator to be licensed by INFARMED for that purpose. For personal use, medicines can be transported only for the necessary period, provided that they are accompanied by a medical prescription when necessary. In the case of emergencies or donations, INFARMED will assess each case individually.

The following regulations are to be considered upon the importation of any products into the Portuguese territory, which is part of the customs territory of the European Union:

• Regulation (EU) 952/2013 of the European Parliament and of the Council of 9 October 2013, which approves the Union Customs Code;
• Commission Delegated Regulation (EU) 2015/2446 of 28 July 2015; and
• Commission Implementing Regulation (EU) 2015/2447 of 24 November 2015.

Portugal is part of the EU and a single European market. It applies the principle of free movement of goods and services and has harmonised regulatory rules for medicines and medical devices.

Price Control for Medicines

Non-reimbursed medicines have free pricing arrangements, whereas all other medicines are regulated and subject to maximum or notified price rules. They cannot be sold unless the MA holder obtains a retail price (RP).

The RP of the medicine is composed of:

• the ex-factory price (EFP), which is the maximum price at the stage of production or import and has fixed rules for its determination;
• the wholesalers’ and retailers’ selling margins, as fixed by ministerial order;
• the tax on the sale of medicines; and
• value-added tax (VAT).

MSRMs intended for use in National Health Service (NHS) establishments are also subject to maximum price rules. Their final price is composed of:

• the EFP;
• the sales tax; and
• the VAT.

The prices of medicines subject to the maximum price rules are reviewed annually. The pricing rules for medicines are set out in Decree-Law 97/2015 of 1 June 2015 and regulated by several Ministerial Orders, in particular:

• Ministerial Order 195-C/2015 of 30 June 2015; and
• Ministerial Order 154/2016 of 27 May 2016.

Requests for price authorisation and price revision communications follow their own procedures and are submitted to INFARMED by the MA holder.

Price Control for Medical Devices

As a rule, State-financed medical devices have fixed maximum prices. Medical devices not financed by the State have free pricing.

The pricing rules for medical devices are set out in Decree-Law 97/2015 of 1 June 2015, and there are Ministerial Orders that define the maximum prices applicable to certain devices or groups of medical devices, which usually include the marketing margins and VAT. In these cases, the RP proposed is indicated by the manufacturer at the time of the request for reimbursement to INFARMED, which follows its own procedure.

Medicines

The prices of medicines are generally set and reviewed based on the prices in reference countries with comparable GDP per capita or the lowest price level, as defined annually among EU countries.

Ministerial Order 394/2025/1 of 14 November has designated Spain, France, Italy and Belgium as reference countries for 2026.

Medical Devices

Medical device prices do not depend on the prices applied in other countries.

Public funding of medicines and medical devices depends on an application to INFARMED by the MA holder or the manufacturer, respectively (Health Technology Assessment). This public financing may be full or partial and differs according to various factors, such as pathologies or special groups of patients, therapeutic indications, the prevalence of certain diseases in the population, etc (see 8.4 Cost-Benefit Analyses for Pharmaceuticals and Medical Devices).

Medicines

As a rule, State funding of medicines is cumulatively subject to prior scientific demonstration of therapeutic innovation or equivalence for the therapeutic indications claimed, as well as demonstration of the economic advantage of the medicine. These factors are not decisive in setting the prices of medicines, given that prices tend to be fixed, taking into account those in the reference countries (see 8.1 Price Control for Pharmaceuticals and Medical Devices and 8.2 Price Levels of Pharmaceuticals or Medical Devices). In the case of the acquisition of medicines for use in the NHS, additional negotiation/commercial conditions may also apply.

Medical Devices

A cost-benefit analysis is also carried out in the State’s funding of medical devices, considering the therapeutic innovation demonstrated for the clinical purposes claimed and the demonstration of an economic advantage (see 8.1 Price Control for Pharmaceuticals and Medical Devices).

In the case of the acquisition of medical devices for use in the NHS, additional negotiation/commercial conditions may also apply.

To support the financial sustainability of the NHS, reimbursed medicines must be prescribed using the international non-proprietary name. The commercial name may only be used in the exceptional circumstances expressly provided for by law. Pharmacies must inform the patient about the medicine that, in compliance with the prescription, has the lowest price. These rules apply to reimbursed medical devices with the necessary adaptations.
